Sirenian Evolution
(Manatee, Sea Cow, Dugong)
Sirenians and Elephants are evolved from a common ancestor. Like whales, sirenians returned to the water. Though hind limbs on whales may be rare and difficult to witness, many sirenians (not all) still retain vestigial toenails like their elephant cousins, and share other traits in common with modern elephants.

    Dolphin Hind Limbs

    TOKYO Nov 5, 2006 (AP), Japanese scientists reported a bottlenose dolphin, has an extra set of fins that could be the remains of hind limbs. The dolphin was captured alive in western Japan on Oct. 28, by Fishermen. "I believe the fins may be remains from the time when dolphins' ancient ancestors lived on land," said Seiji Osumi, of Tokyo's Institute of Cetacean Research. The hind fins are much smaller than the front fins and are about the size of human hands, protruding near the tail. The dolphin measured approx 9 feet in length.

VERY interesting! THANKS very much for remembering to send me a copy! What a fine new article on how Cetacean embryo hind limbs develop in the womb and then disappear. Handy photos too! Now how can we get such photos shown to every creationist on earth, especially the folks at "Answers in Genesis?"

I think that perhaps the folks at Talk Origins Archive, The Panda's Thumb website/blog and also the editor of Discover magazine and his Corante blog might like to see those photos and read the article as well, since they keep up with the latest evidence there and debate creationists. Not to mention the "No Answers in Genesis" website.

Will your article soon be on your whale evolution website soon so people can read it, view the photos and link to it? It needs to be. The world needs to know, and to see!

Wikipedia features links to your whale evolution website, but I do not see a link to Gingerich's university website.
See: http://en.wikipedia.org/wiki/Evolution_of_cetaceans

I seem to recall Wikipedia as linking to the photos of hind limbs of modern day cetaceans that are at edwardtbabinski.us but I no longer see the link listed.

Great!!!!! Send photos!

Don't whale embryos also have hair that is reabsorbed later during development? I don't have any photos of that.

And Baleen whale embryos have teeth that later are reabsorbed and then baleen develops, right? Would love to have some photos of that too!

And if you hear (or rather see) any new photos of adult whales or dolphins with hind limb rudiments, please let me know! Or I guess I should stay posted to your website. The public is tremendously ignorant of such evidence. Though it's a good sign that creationists once used to cite the evolution of whales in their debates as the supreme example of something for which evolution could NEVER account. Today the example they cite the most are bats, since the fossil record remains sparse there.

Ed, you are right about all your statements about cetaceans.
At this point, I only have embryos for one species, Pantropical Spotted Dolphin. Those have about 10 hairs on either side of the face as an early fetus. Baleen whales have many more (even as newborns), and I am getting fetuses for those, but don't have them yet. Yes, you are right that (some?) baleen whales also have teeth that do not erupt, I have never seen good photographs of them, but there are some drawings in old papers. That too, I hope to get good ones when I get the mysticete embryos.
Attached are a couple of figures which you may post on your website or share with others. I do want to retain the copyright to them, so please say that in the caption, and eventually will also post them on mine or publish them in print.

Hind Limb Rudiments on Modern Whales Example Five

HIND LIMB RUDIMENTS FOUND ON MODERN DAY WHALES

EXAMPLE #5

Here are some interesting facts concerning the pelvic anatomy of the majority of modern day whales, rather than the rare exceptions already noted above:

"The existence of a pair of small pelvic bones is known to exist in nearly all of the Cetacea, lying far apart from the vertebral column on both sides of the genital opening. However, in the Fin Whale, the Blue Whale, and the Humpback, the femur too is present near the pelvis. [Even in the Sperm Whale the femur is sometimes present (in the form of a small round-shaped bone near the pelvis). - E.T.B.] And in the Right Whale not only the femur but also the tibia exists. Of course these bones are buried deeply under the skin, causing no protuberance on the body surface." [Ogawa]

Whale Evolution Graphic - Right Whale
Right whale picture 1
the Femur and Tibia of the Right Whale
This goes with EXAMPLE #5
F = Femur (thigh bone)
T = Tibia (lower leg bone)

SEE THE TWO DIAGRAMS OF THE RIGHT WHALE'S PELVIS, FEMUR AND TIBIA (based on dissections by Struthers)

"Nothing can be imagined more useless to the animal than rudiments of hind legs entirely buried beneath the skin of a whale, so that one is inclined to suspect that these structures must admit of some other interpretation. Yet, approaching the inquiry with the most skeptical determination, one cannot help being convinced, as the dissection goes on, that these rudiments [in the Right Whale] really are femur and tibia. The synovial capsule representing the knee-joint was too evident to be overlooked. An acetabular cartilage, synovial cavity, and head of femur, together represent the hip-joint. Attached to this femur is an apparatus of constant and strong ligaments, permitting and restraining movements in certain directions; and muscles are present, some passing to the femur from distant parts, some proceeding immediately from the pelvic bone to the femur, by which movements of the thigh-bone are performed; and these ligaments and muscles present abundant instances of exact and interesting adaptation. But the movements of the femur are extremely limited, and in two of these whales the hip-joint as firmly anchylosed, in one of them on one side, in the other on both sides, without trace of disease, showing that these movements may be dispensed with. The function point of view fails to account for the presence of a femur in addition to processes from the pelvic bone. Altogether, these hind legs in this whale present for contemplation a most interesting instance of those significant parts in an animal -- rudimentary structures." [Struthers, p. 142-143]

The hind-limb bones that Struthers dissected from the right whale are still on display in the Zoology Museum at Aberdeen.

Whales have a number of vestigial structures that would have been fully functional in their land-living ancestors, including the pelvic girdle, the hind limbs and the finger muscles. The forelimbs of whales, which are used for steering, are stiff and paddle like and the muscles of the fingers, although still present, are much reduced, largely non-contractile and act more in the fashion of ligaments.

What's especially interesting about the Right Whale is the fact that Carl Wieland at Answers in Genesis in his article, "The Strange Tale of the Leg on The Whale," featured a photo of "the skeleton of a Greenland Right whale, with bony disease." Well, here are diagrams of a dissection of a perfectly healthy Right Whale, showing its pelvis, femur and tibia. Sure look like "rudimentary hind legs to me," there's the hip bone connected to the leg bone, and the leg bone connected to the shin bone. All hidden inside the body of the Right Whale. Struthers' dissections were performed over a century ago, and revealed them plain as day.

Hind Limb Rudiments on Modern Whales Example Four

HIND LIMB RUDIMENTS FOUND ON MODERN DAY WHALES

EXAMPLE #4

1956 -- Sperm whale caught by Japanese whaling operation, July 5th, 1956, protrusions on either side of the anus.

1954-1961 -- Japanese whaling operations catch 12,761 sperm whales, “so the percentage of the occurrence of the sperm whale with rudimentary hind limbs may be about 0.02 for the total catch in the Bering sea and the northern part of the north Pacific…But I suspect that protruded hind limbs in sperm whales would show a higher percentage if more strict examination were made on all whales caught especially in the land whaling stations flensing many sperm whale in the waters adjacent to Japan.”

1959 -- Sperm whale with protruded rudimentary hind limbs is reported by A. P. Kyodo in the Japanese newspaper, The Mainichi dated May 18, 1959 (based on broadcast from Moscow). “In the legs, there exist bones by examination using X ray.”

1960 -- Sperm whale caught July 16, 1960 by Japanese whaling operation in the north Pacific, a pair of protrusions, each clearly elevated like a dome on either side of the anal groove, white circular spot (cartilage) in the center of the cut protrusions extends as far as half of the dome. (See Fig. 8)

1962 -- Sperm whale with protruberances caught in Kuril waters. Protruberances contain undeveloped thigh bones. (Soviet news published by Soviet embassy in London on May 22, 1962.)

Hind Limb Rudiments on Modern Whales Example Three

HIND LIMB RUDIMENTS FOUND ON MODERN DAY WHALES

EXAMPLE #3

1956 -- Female Sperm Whale caught by Japanese whaling operation, Nov. 8th, 1956, “protuberances on both sides of the genital opening. … The height of the protuberance was 5.35 centimeters on the right side, 6.56 centimeters on the left side.” (SEE PHOTOS OF THE PROTRUSIONS FROM SIX DIFFERENT ANGLES, Fig. 5)

“Upon examining the interior of the left limb three partially cartilaginous bones were found. They correspond to pelvis, femur, and possibly to tibia, but no joints exist between them. Pretty strong muscles connect between femur and tibia. The tibia is 13 centimeters long for the greater part cartilaginous, and only partly ossified stick-like body with its distal end inserted into the skin of the hind-limb protuberance. (SEE THE SCHEMATIC DIAGRAM BASED ON THE DISSECTION [Fig. 6] AND ALSO SEE THE PHOTOGRAPH OF THE DISSECTED HIND LIMB RUDIMENTS [Fig. 7]) A number of arteries and nerves run parallel to this tibia distalward. … The veins are not easily visible by the naked eye, but they are found attached intimately to the wall of arteries. This case can be understood by assuming abnormal retention of the early embryonic state, and show very probably an atavism back to the quadripedal condition of the whale’s remote ancestors. It can never be a malformation of no phylogenetic significance.” “We searched into the interior of the left limb. The pelvic bone was found there. … In the neighborhood of the pelvis, nearly at the middle part of this bone, the femur covered with cartilage is present taking the form of a small ball with the diameter ca. 3 centimeters. … 4.8 centimeters distant from the femur a mostly cartilaginous stick of the length 13 centimeters is present. It is only partially ossified. ... It is difficult to determine whether this stick corresponds either to tibia, fibula, or both of them fused together, or rather to an isolated distal portion of femur. But we take it provisionally for tibia in view of two slender muscles coming from the femur, and inserting to the anterior surface of the bony part of the stick. … The distal end [of the tibia] lies in the central part of the hind limb protrusion.” (SEE THE SCHEMATIC DIAGRAM BASED ON THE DISSECTION [Fig. 6] AND ALSO SEE THE PHOTOGRAPH OF THE DISSECTED HIND LIMB RUDIMENTS [Fig. 7]) “Two weak muscles (M5 and M6 in Fig. 6) are attached to the osseous tibia by intercalation of tendons. For the time being we take these muscles for the rudimentary mm. vast. … Our attention was further given to the richness of nerves and arteries pertaining to the limb. All of them run nearly parallel to the tibia in the proximal-distal direction … As to large arteries we have counted six of them (A1, A2, A3, A4, A5, A6 in Fig. 6) at the proximal end of the tibia. It is noteworthy that most of them reach the interior of the protruded limb. … All of the nerves destined to the hind limb are continuous from a thick trunk (N1+2) passing through the triangular space between pelvis and femur mentioned above (S). … Nerves and arteries run at first ventral to the pelvis, then dorsal to the femur, to reach further the tibial region.”

Hind Limb Rudiments on Modern Whales

HIND LIMB RUDIMENTS FOUND ON MODERN DAY WHALES

EXAMPLE #2

In July 1919, a female Humpback Whale with two remarkable protrusions on the ventral side of the body, posteriorly, was captured by a ship operating from the whaling station at Kyuquot, on the west coast of Vancouver Island, British Columbia [Canada]. One of the protrusions was cut off by the crew of the vessel but the other was photographed in situ by the superintendent of the Station. (Figure #3) Mr. Sidney Ruck and Mr. Lawson, officials of the Consolidated Whaling Company, appreciated the importance of the discovery and presented the skeletal remains of the attachment to the Provincial Museum, Victoria, B.C. [Canada]. At my request, Mr. Francis Kermode, Director of the Provincial Museum, very courteously submitted the bones to me with permission to publish upon the result of my examination.

Under date of March 4, 1920, Mr. Ruck writes to Kermode as follows: “I enclose herewith three photographs showing the unusual development of the pelvic Rudiments in a whale captured at the Kyuquot Station last July, of which you have the bones. It is to be regretted that better pictures in evidence of this unprecedented development were not obtained. I have been connected with the Whaling Industry for 22 years and during my time have come in contact with prominent Naturalists such a Professor True of the Smithsonian Institute, Professor Lucas of the Natural History Museum, New York, and neither in their experience or mine have the protrusion of the pelvic bones beyond the body ever been seen or heard of. This particular whale was a female Humpback of the average length with elementary legs protruding from the body about 4 feet 2 inches, covered with blubber about one-half an inch thick. As shown in the best photograph these legs protruded on either side of the genital opening; the left leg was cut off by the crew of the vessel and lost, and the point at which it was cut off is clearly shown in the photograph. The end of the leg seen in the picture terminated in a kind of round know like a man’s clenched fist. The two bones of the leg which you have are connected by cartilage which I was informed had shrunk about 10 inches, and possibly more by this time. At any rate the total length of the leg before it was cleaned of the blubber and flesh was, as before stated, about 4 feet, 2 inches, from the body.”…

Hind Limb Rudiments Found on Modern Day Whales

The skeletal remains in my possession consist of two bones and two heavy cartilages. When placed in position (see Figure #4), the total length is 31 inches.

Hind Limb Rudiments Found on Modern Day Whales - Figure 4

FEMUR (a long cartilage) -- The larger bone is deeply concave proximally and to it is attached a massive cartilage which, in its present shrunken condition, is 5 ¼ inches in length and 1 5/8 inches wide. I estimate that this cartilage was at least 15 inches long and 3 inches wide when fresh. I believe that this cartilage represents the femur. It probably lay entirely within the body, its proximal end being attached to the pelvic vestiges. Such a massive cartilage much necessarily have had a firm support and leads me to believe that the pelvic elements in this individual were of extraordinary size. …

TIBIA (the longer of the two bones) -- The larger of the two bones I identify as the tibia. It is 14 ¼ inches in greatest length, is well developed, and has a hard, smooth outer surface. At the proximal end its greatest width is 3 ¾ inches, it narrows gradually for three-fourths of its length, and then suddenly expands at the distal extremity, where it is 2 ½ inches wide.

TARSUS (another cartilage) -- The distal end of the tibia is convex and gives attachment to a cartilage which in its shrunken state is 4 ¾ inches long and 1 ¾ inches wide. This cartilage, I believe, represents the tarsus. That it presents not ossifications is by no mean surprising as the carpal bones in the forelimbs of cetaceans are sometimes entirely absent and often in a more or less rudimentary condition. Mr. Ruck says “the two bones of the leg which you have are connected by cartilage which I was informed had shrunk about 10 inches and possibly more by this time.” This would give the tarsal cartilage a lengthy of nearly 15 inches. METATARSAL (the shorter of the two bones) -- The distal element in the leg is a hard, well-developed bone which I identify as a metatarsal. It has the characteristic shape of the metacarpals in the fore limbs of cetaceans except that it is more slender. It is 6 1/8 inches long. 1 7/8 inches in distal width; its least width is 15/16 of an inch. To the distal end of the metatarsal is attached a heavy cartilage of which only 3/4/ of an inch remains intact. This cartilage probably formed the extremity of the hind limb skeleton.

EXTERNAL APPEARANCE OF THE LIMB -- In reference to the limb as it appeared in the fresh condition, Mr. Ruck says that the end terminated in a “kind of round knob like a man’s clenched fist,” that the total length was about four feet and two inches, and that it was covered with blubber about one-half inch thick. I infer from Mr. Ruck’s description that the connective tissue and blubber were essentially the same as in the flipper, or fore limb, of cetaceans. The photograph of the limb in situ show that there are two prominent, truncated tuberosities on the distal half. The proximal “bunch” evidently indicates the distal end of the tibia and the other is at the extremity of the metatarsal. These tuberosities may very properly be homologized with those on the other, or anterior, edge of the flipper in the Megaptera (Humpback Whale) which indicate the extremities of the radius and the second digit. This is, I believe, a point which has considerable significance.

Hind Limb Rudiments Found on Modern Day Whales
Figure 5
This photo goes with the following example, EXAMPLE #3

Since the stalk-like cartilaginous femur probably lay entirely within the body and the remainder of the limb entirely outside, there was undoubtedly a certain flexibility at the point of junction with the body.

In 1914 Professor W. Kikenthal described external rudimentary hind limbs in three early embryos of Megaptera (Humpback Whale). These appear as two more or less caudally directed papillae on either side of the genital organ in the same relative position as the himb limbs which I have described in this paper. In Kukenthal’s Stage 1 (an embryo 32 mm. In length) the rudiments are best developed and are 1.2 mm. Long. In Stage II the rudiments are somewhat less distinct…In Stage III (an embryo 30 mm. Long) the hind-limb rudiments have still more decreased in size and appear as minute papillae. Kukenthal and Guldberg have also discovered hind-limb rudiments in embryos of other cetacean species. Since Kukenthal’s and Guldenberg’s researches have shown that external hind-limb rudiments are still present in some cases [actually in “all” cases -- E.T.B.] in embryonic life, it is by no means impossible that, these vestigial organs should continue their growth and persist until the adult stage. I believe that that is exactly what has occurred in the specimen which I have described above, and that we are confronted with a clear case of partial reversion to a primitive quadripedal condition. The limbs, according to the statements of the whalers, were symmetrical; they are in the exact position in which hind-limb rudiments have been found in embryonic Megaptera (Humpback Whales); there are strong indications that the cartilaginous femur was attached to the pelvic elements; they are homologous in many respects to the flippers, or fore limbs, and, were this a teratological case [say, due to a rare biological monstrosity or malformation], it is doubtful if these homologies would exist. Unwilling as are many evolutionists to accept reported cases of reversion, I can see no other explanation for the facts presented here. That this condition is extremely rare must certainly be true for, so far as I am aware, this is the only recorded case among cetaceans.

Andrews, “then of the National Museum, now of the American Museum of Natural History,” was writing in 1921. No whales with hind limb rudiments as long as those he described have since been found, except perhaps for one catch in the Gulf of Alaska by Soviet whalers in 1964 of a Sperm Whale with hind limb rudiments not covered by skin and similar to those described by Andrews -- the authors who mentioned this other find also mentioned “no detailed description and no illustrations are available” of that catch. Which is not to say that further examples of hind limb rudiments of shorter lengths have not been discovered. They have. See further examples below. -- E.T.B.]

Hind Limb Rudiments on Modern Whales Example One

HIND LIMB RUDIMENTS FOUND ON MODERN DAY WHALES

EXAMPLE #1
In 1958 we examined a male Sperm Whale 11.6 meters long caught in the Bering Sea, with unusual protrusions in the pelvic region and along the sides of the genital fold (see Figure #1) with a total length of 28 and 34 centimeters, pigmented like the rest of the body. The section of the left protrusion that extended from the body had the appearance of the rounded blade of a propeller, while the right one looked like a fin with finger-shaped processes. The bones were enclosed in dense connective tissue. Judging from an X-ray photograph (see Figure #2) of the skeleton of the protrusions in this specimen, the section of the protrusions that lay inside the body corresponded to the femur, and the middle section to the tibia and the fibula. The section of the protrusions that extended from the body corresponded to the step of the hind limb, and the elements composing it are probably phalanges of the digits. According to the number of phalanges visible in the X-ray photograph, these are the fifth and fourth digits. The skeleton of these limbs is distinguished from the typical structure of the skeleton of the pentadactyl limb of mammals by the absence of tarsal elements. It may be, however, that they were simply not found due to their small size, weak ossification, and the abundance of connective tissue.

Review of Strange Tale of the Leg on the Whale

Cetacean Evolution (Whales, Dolphins, Porpoises)
Evidence of Common Ancestry of Cetaceans and Certain Species of Land Mammals
by Edward T. Babinski

(Reviews of several creationist articles that deny such evidence exists.)

REVIEW OF "The Strange Tale of the Leg on the Whale" by Carl Wieland

The author of the above article denies that the vestigial pelvic bones in modern day whales (which are also found in other cetaceans like dolphins and porpoises) is a vestigial pelvis. He writes: "They [evolutionists] believe this even though these strips of bone have a known function [to anchor the male reproductive organ], differ in males and females, and are not even attached to the vertebral column." The author apparently does not consider that vestigial organs can also be put to new and different uses which is one of the hallmarks of nature's jury-rigged ways. And the fossil record of early whales includes one with a tiny pelvis and tiny rear legs (Basilosaurus) possibly used to aid in copulation, so the adaptation of the vestigial pelvis bones in modern whales (as an anchor for the penis) seems to have an evolutionary pedigree. The fossil record of whales eventually includes critters with a pelvis that no longer articulates with the vertebral column. So the identification of those small bones in whales / dolphins / porpoises as a "vestigial pelvis" suggests itself rather neatly. (Interestingly, outside of the whale family, snakes have puny vestigial pelvis bones too, where the pelvises of their ancestors used to be.) The author denies that "vestigial femurs" which are found where a femur would normally be located (near, or attached to the whale pelvis and pointing downward on both sides of the pelvis) are "vestigial femurs." He says these are perhaps DNA malfunctions or signs of bone disease. The author includes a section titled, "Myth Tracked Down," concerning the story in a Danish science textbook (E.J.Slijper, Whales) about a bump identified as a "tibia" on a Sperm whale. The author calls the "tibia" identification a "myth." Actually such "myths" have been documented with X-Rays according to A. V. Yablokov, Variability of Mammals (1974) who examined a number of such discoveries personally after they were discovered at whale factories in Russia. There were different varieties of such "bumps" that were found to contain remnants of a femur, remnants of a femur and the metatarsus, and, in some cases even remnants of a femur, metatarsus and phalanges [toe bones]. As for Yablokov's first hand testimony, it is not the only one: "There are many cases where whales have been found with rudimentary hindlimbs in the wild (for reviews see Berzin 1972, pp. 65-67 and Hall 1984, pp. 90-93). Hindlimbs have been found in baleen whales (Sleptsov 1939), humpback whales (Andrews 1921) and in many specimens of sperm whales (Abel 1908; Berzin 1972, p. 66; Nemoto 1963; Ogawa and Kamiya 1957; Zembskii and Berzin 1961). Most of these examples are of whales with femurs, tibia, and fibulae; however, some even include feet with complete digits."

Nor does the author mention whale embryology : "Modern adult whales, dolphins, and porpoises have no hind legs. Even so, hind legs, complete with various leg bones, nerves, and blood vessels, temporarily appear in the cetacean fetus and subsequently degenerate before birth."

The Evolution of Whales

Dolphin Hind Limbs


TOKYO Nov 5, 2006 (AP), Japanese scientists reported a bottlenose dolphin, has an extra set of fins that could be the remains of hind limbs. The dolphin was captured alive in western Japan on Oct. 28, by Fishermen. "I believe the fins may be remains from the time when dolphins' ancient ancestors lived on land," said Seiji Osumi, of Tokyo's Institute of Cetacean Research. The hind fins are much smaller than the front fins and are about the size of human hands, protruding near the tail. The dolphin measured approx 9 feet in length.

REVIEW OF The strange tale of the leg on the whale
by Carl Wieland
(Continued)
The author states, "Pakicetus was claimed to be a 'walking whale' ? yet the type specimen consisted only of jaw and skull fragments." The author's statement is dated. More bones of Pakicetii have been found, and it appears to have been a walking relative of whales.

Also, a lot can be learned from "only jaw and skull fragments." Here's the rest of the story of those fragments: "One particularly baffling fossil was the back part of a 50-million-year-old skull. It was about the size of a coyote's and had a high ridge running like a mohawk over the top of its head, where muscles could attach and give the mammal a powerful bite. When Gingerich looked underneath the skull, he saw ear bones. They were two shells shaped like a pair of grapes and were anchored to the skull by bones in the shape of an S. For a paleontologist like Gingrich, these ear bones were a shock. Only the ear bones of whales have such a structure; no other vertebrate possesses them."

- Carl Zimmer, "Forward Into The Past: The Origin of Whales," a section in Evolution: The Triumph of an Idea "The position of the inner ear bones in Pakicetus are a perfect intermediate between those of land mammals and the rotated ones of cetaceans (Thewissen & Hussain, 1993), not to mention the fact that the tympanic bullae are composed of dense bone as those of cetaceans (Gingerich, et al, 1983)."
"Pakicetids were the first cetaceans, and they are more primitive than other whales in most respects. In fact, they did not look like whales at all, and did not live in the sea. . .Although . . . it is clear that they are related to whales and dolphins based on a number of specializations of the ear, relating to hearing.

Hind Limbs on Whales: Gingrich

In an article from February 1991, National Geographic Magazine reports a scientific team partly funded by National Geographic, and lead by Philip Gingerich (University of Michigan) discover fossilized bones and feet from a whale that lived forty million years ago, in what is now a desert, located southwest of Cairo, Egypt. N.G. asks, "Since the limbs were so tiny, what purpose did they serve?" The team uncovered remains of 243 archaic whales.
"The legs were weak and the feet too small for walking or swimming or to support the whale," says Gingerich. He feels since they're attached to the pelvic region, perhaps they were used to help guide the male during mating, while other experts remain skeptical.

"Ichthyolestes. . . and Pakicetus. . . had meat eaters' teeth, but were not genuine canines, having longer, more powerful tails, longer snouts and smaller eyes than dogs. . .The two also have "several strange bones in their ears that occur only in whales," says Hans Thewissen, of Northeastern Ohio Universities College of Medicine in Rootstown, Ohio, one of the fossils' finders."

"The ear of modern whales and dolphins is specialized to listen to sounds underwater. . . The hearing organ of Eocene whales was not specialized as that of modern cetaceans. Instead it represents a compromise of adaptations relating to underwater sound reception and hold-overs of a hearing system used for listening to sounds in air. The eardrum of these cetaceans is more flat than that of their modern relatives, and the external auditory meatus is still present." Scientists have found a lot of fossils that show what the ear was like in Eocene whales."

[The adaptation of the ear bones of these land mammals (for increased hearing and sense of balance under water) preceded the diminution of limbs and other skeletal changes that eventually adapted such critters to the sea.

See Nature, May 9, 2002 -- E.T.B]

And here is a bit of information on the teeth found in these "jaw and skull fragments" of early whales: "The skulls of Eocene whales bear unmistakable resemblances to those of primitive terrestrial mammals of the early Cenozoic. Early [whale] genera retain a primitive tooth count with distinct incisors, canines, premolars, and multirooted molar teeth. Although the snout is elongate, the skull shape resembles that of the mesonychids, especially Hapalodectes. . . Pakicetus (early-mid Eocene, 52 mya), the oldest fossil whale known, had the same skull features as Hapalodectes . . . Molars still have very mesonychid-like cusps, but other teeth are like those of later whales. . .Whale-like skull crests and elongate jaws." [Skipping past Pakicetus and other early whales and going right to Eocetus of the late Eocene, even those whales] which have lost their hind legs entirely, still retained a 'primitive whale' skull and teeth, with unfused nostrils . . . This stage of aquatic adaptation was attained about 15 million years after the first terrestrial mesonychids."

"Living whales have either no teeth or simple pegs. But the teeth of the oldest known whales looked particularly like the teeth of an extinct line of mammals called mesonychids. These animals were hoofed mammals. . . but they had powerful teeth and strong necks adapted for a life of eating meat. . .The teeth of the oldest known whales still resembled those of mesonychids in their general outline, but they were already changing. . . long gouges run along the outward sides of the lower molars. These gouges formed as the whales scraped their molars with their upper teeth. The whales had to have been making only vertical bites, not side-to-side chewing, to form them. There's fossil evidence that later whales, which also had these gouges, fed on fish. That has led to the view that Pakicetus and its contemporaries had already started eating fish or other aquatic animals."
- Carl Zimmer, "Forward Into The Past: The Origin of Whales," a section in Evolution: The Triumph of an Idea

Since the late 1970s professor Phil Gingerich has collected fossil specimens of early whales from remote digs in Egypt and Pakistan. Professor Hans Thewissen, another cetacean evolution paleontologist, is a former student of Gingerich. According to Gingerich, "I grew up in a conservative church in the Midwest and was not taught anything about evolution. The subject was clearly skirted. That helps me understand the people who are skeptical about it. Because I come from that tradition myself." He shares the same skeptical instinct. Tell him that there's an ancestral connection between land animals and whales, and his reaction is: Fine, maybe, but show me the intermediate stages. Like Charles Darwin, the onetime divinity student, who joined that round-the-world voyage aboard the Beagle instead of becoming a country parson, and whose grand view of life on Earth was shaped by close attention to small facts, Phil Gingerich is a reverent empiricist. He's not satisfied until he sees solid data. That's what excites him so much about pulling whale fossils out of the ground. In 30 years he has seen enough to be satisfied. For him, Gingerich said, it's "a spiritual experience." "The evidence is there," he added. "It's buried in the rocks of ages."

Pelvic Bones on Whales, Ambulocetus

Cetacean Evolution (Whales, Dolphins, Porpoises)
Evidence Of Common Ancestry of Cetaceans and Certain Species of Land Mammals
by Edward T. Babinski

ANSWERS IN GENESIS: AMBULOCETUS' MISSING PELVIC GIRDLE? ...BACKBONE? LEG BONES?

Ed Babinski's Reply to Answers in Genesis

The question of "who said what, and when," will be forgotten as time goes on, and hence it is not quite as important as the question of what the evidence for cetcean evolution means. If Sarfati can't even acknowledge that evidence for evolution exists, then pointing out dates to him of what he said and when he said it, isn't going to change his mind on evolution. And even though he spoke hastily about the pelvis not being there in that fossil, he can always write a new article about the latest evidence and include mention of the pelvis but deny that it means anything in his opinion, hence, denial after denial. Fact is, AiG is horrible at seeking out information. After being told about scientists discovering hind leg rudiments on modern day whales, they failed to seek for the original scientific articles, even after exact references were given to them, instead posting a pic of a diseased whale skeleton. They didn't even want to obtain the articles about whale hind-leg rudiments from Interlibrary loan, because the references for such article were posted on a site run by "talk origins," and they categorize everything at that site as lies. And when I obtained the actual articles and posted the pics and info online, Sarfati continued to deny that such sources meant anything, and he mocked me and my website. I'm not sure he even looked at the info. He is a preacher damning other people eternally for not agreeing with him. He truly fears evolution more than I fear his "hell for non-born agains."

AiG's website "A Whale of a Tale, Addendum" 2 (4 January 2002)") admits that the original article in which they criticized the fossil evidence for cetacean evolution was merely based on discoveries reported at the time the original AiG article was written. And AiG questioned whether the latest cetacean fossil discoveries had been peer reviewed, or whether the new evidence was anything more than a jumble of bones. For young-earth creationists it's the same method of denial in every case, harkening back to the days of Gish at ICR. Take primate evolution. We have primate skulls with cranial capacities lying between higher apes and human beings, skulls whose pedigrees even creationists can't agree on, are they the skulls of "apes or men?" Creationists can't agree which skulls belong to which category. How inspiring! Still, they are not going to admit that ANY evidence for the transformation of living organisms over time is the least bit "clear." Perhaps if you could point a young-earth creationist to a geological deposit in which one species of animal died directly on top of its daddy/mommy, and that pattern continued indefinitely so you could catalog evolutionary changes without a single "gap," they would take note. Though some would probably assert instead instead that the Flood had miraculous sorting properties. What they neglect is a sense of proportion regarding geology and paleontology. Cetacean fossils are not found everywhere in the fossil record, but only in specific places. In fact the geological records as a whole exhibits sorting to a far greater degree than "Flood geology" can account for. Fossils (from the most microscopic fossils to large plant fossils to fossil fragments to "trace" fossils to large complete fossilized organisms) are found in astonishingly accurate relative orders around the world, and exhibit a degree of relative sorting such that geologists before Darwin's day were doubtful any "Flood" could sort things in such a fashion. Young-earth creationists are still only beginning to come to grips with their own "Piltdown and Nebraska man" type errors of enthusiasm, and yet they have uncovered no new startling evidence to replace the formerly enshrined "Paluxy mantracks" or the "sightings of Noah's Ark" (the mountain on which Noah's Ark searchers have concentrated their past searches is a mountain that was formed volcanically! Mustta been pretty hot when Noah got there, and its elevation hard to breath, and sides steep and dangerous). Snelling at AiG even despairs of finding the ark on Ararat and despairs that any unequivocal evidence of "pre-Flood man" or his dwellings or tools or other creations may ever be discovered in the geological record, though we do find plenty of what he calls "pre-Flood" animal and plant remains.

Of course if young-earth creationists took the time, they might learn to recognize why geologists are not wowed by "evidences of a young-earth," and might even learn to recognize the distinguishing differences displayed in earlier forms of fossilized organisms when compared with later ones, and see for themselves that various specializations did not all occur early on, and in fact the earlier species of cetaceans resembled land animals more than later cetaceans did, and the ealier forms of cetaceans were less well adapted to living their entire lives at sea than the more recent forms are. But since they can't even get past the fact that the geological layers are not as mixed up as their "Flood geology hypotheses" assumes, how do you intend for them to also recognize the telltale differences between early, mid, and modern cetacean species, and notice the lack of specialization of the earlier species compared with later ones?

Neither do they see any need to understand such matters, since they "understand" Genesis just fine, and they are certain that is all they really need to know, i.e., how to count up to "six days."

Image based on the image located on AiG, as is on Dec. 02, 2004 compared to image based on a photo image (below) featured in a November 2001 copy of National Geographic, "The Evolution of Whales".


The author explains the three images:
1) Top: Ambulocetus skeleton, as drawn in Miller’s book
2) Middle: Ambulocetus reconstruction, as drawn in Miller‘s book
3) Bottom: Actual bones found (Yellow). Note missing pelvic girdle.

The question that comes to mind is if this was a deliberate attempt to mislead AiG readers, or simply an oversight due to negligence on behalf of Dr. Jonathan Sarfati? The fossil certainly does include backbone, leg bones, and pelvic bones. As is noted in the paraphrased excerpt below from National Geographic, Professor Hans Thewissen was discussing the spine of Ambulocetus as early as 1994, it would seem Answers in Genesis would be aware of this fact, ten years later.

Dr. Jonathan Sarfati:
On p. 265, Miller claimed, ‘the animal could move easily both on land and in water’, and contained a drawing of a complete skeleton and a reconstructed animal. But this is misleading, bordering on deceitful, and indicative of Miller’s unreliability, because there was no indication of the fact that far fewer bones were actually found than appear in his diagram. Crucially, the all-important pelvic girdle was not found (see diagram, right). Without this, it’s presumptuous for Miller to make that proclamation.

Below is an image based upon an actual photograph of an Ambulocetus fossil.
Note the presence of a pelvic region, including spine and leg bones which were all ommitted from Answers in Genesis sketch.

Ambulocetus

Ambulocetus natans as it is called, is currently the eldest known saltwater cetacean, according to National Geographic, page 72, November 2001 "The Evolution of Whales". Professor Hans Thewissen is quoted as saying, "With long hind legs and hands, but the teeth and ears of a more modern whale, this animal was on the fence between land and sea."

In a May 1994 issue of National Geographic, it reports the find of Ambulocetus in a former inland sea of Pakistan. Thewissen dubbed the ancient whale fossil Ambulocetus natans for "swimming, walking whale". He explains, on land it would lumber like a sea lion, and "it would look clumsy, but it could still get around." His team recovered much of the fossil including a skull which identified the fossil as a cetacean. The spine indicates the creature moved in similar fashion to modern whales, using its lower back in an up and down motion, while using its hind limbs for propulsion. It's forelimbs are believed to have been used for steering.

Judging excerpts from the article, one can safely deduce Jonathan Sarfati had never actually seen the fossil for himself[?]
Dr. Sarfati really should update his information on occasion.

How long has the information been available to scientists on the fossilized pelvis bones of Ambulocetus?
I was in question why Dr. Jonathan Sarfati does not have current information available on the Answers in Genesis website. I contacted Professor Hans Thewissen to verify exactly when the pelvis bones were discovered and knowledge about them dispersed to scientific circles? Should not have Jonathan Sarfati known about these pelvis bones earlier than the year 2004? If he has had knowledge, then I ask why has he neglected to update his web page?

Question on Ambulocetus Discovery

Dear Professor Thewissen,

When exactly was the spine, the leg bones, the pelvic girdle discovered of Ambulocetus?

This morning I decided to take a look at Answers In Genesis where Dr. Jonathan Sarfati is arguing against the PBS Special #2 "Evolution:Great Transformations".


Dr. Sarfati is saying there is no spine, no pelvic bones, no leg bones -- and you were discussing the spine of Ambulocetus as early as 1994, and I have a reconstructed photo image of the Ambulocetus -- which appear to be very much complete! Where he got his information is questionable -- and I suspect he has never seen this fossil.

Thank you sincerely for your time

Re: Question on Ambulocetus Discovery

The specimen was dug up in two phases, results from the first were published in 1994, results from the second in 1996. In 1994, we described some vertebrae, most leg bones, but no pelvis. In 1996, we described many more vertebrae, as well as the pelvis. So inferences about the spine in 1994 were based on the vertebrae we had then. The figure we published in 1994 shows, in stippling, what was known and not-known for the specimen at that time. So there is really no reason why anyone should be misled (as long as they take the trouble to go back to the original publication).

The reason for the delay between the two publications sounds like somewhat from a police movie. We tried to go back and collect the rest of the specimen before the publication in 1994. However, the region had turned in a haven for outlaws. On the day that we were going to start to work there, a man had been kidnapped and a large number of policemen was stopped along the road there to confront the kidnappers. They told us to keep on driving and not stop on that road where the action was happening. At that point, I decided that there was no point waiting to collect more material, because it was not obvious that we would ever be allowed (able) to go back to the site.

Hans Thewissen

This explains why Sarfati was referencing a journal from 1994 in his article, although he should have known the information was updated and changed in 1996 with the new discoveries by Thewissen's team:

fellow evolutionist Annalisa Berta pointed out: ‘ … since the pelvic girdle is not preserved, there is no direct evidence in Ambulocetus for a connection between the hind limbs and the axial skeleton. This hinders interpretations of locomotion in this animal, since many of the muscles that support and move the hindlimb originate on the pelvis.
Berta, A., What is a Whale? Science 263(5144):180–181, 1994; perspective on Thewissen, J.G.M., Hussain, S.T. and Arif, M., Fossil evidence for the origin of aquatic locomotion in Archeocete whales, same issue, pp. 210—212.
http://www.answersingenesis.org/.../0926ep2.asp

Knowing using an out-of-date scientific journal from 1994, when updated (changed) information was available in 1996, for a "refuting" a documentary in 2001.

THAT'S NOT SCIENCE

I contacted Answers in Genesis about their misleading Ambulocetus information. Rather unethical of AiG to write a web page in the year 2001, and using out of date (now, erroneous) information to "back up the claims"[?]

You still have misleading, deceitful and slanderous information located at:

Miller gave an accurate portrait of Ambulocetus. The person responsible for an inaccurate portrayal of the fossil is Jonathan Sarfati, not Miller.

Is it AiG's primary goal to misinform the public?

The inaccurate non-science by Sarfati, is still there at the URL I wrote in about. This is unfair to those Sarfati is rudely attacking (ironically with inaccurate out-of-date, now non-science) and unethical, to both Thewissen's team and Mr. Miller who you are slandering.

Out of context, obsolete information is not science.

If Jonathan Sarfati, PhD cares anything about accuracy, [now having been given information directly from Thewissen himself, saying nobody needed to be mislead, as obviously Sarfati was from the 1994 publication] -- he would change the page now, since he knows better.

It looks like they [Answers in Genesis] left out some of the fossil, doesn't it? Like the pelvis, and many of the vertebra. I wonder why they would do that.


It's misleading people, and misrepresenting the truth. There is no argument. They should remove that awful section from the web before somebody believes they're actually a scientific authority... and goes to debate that false information with people who know better.

You don't put a link to another page and say "Ooops, we deliberately and knowingly made an error, but we're not going to address or correct it."

A lie is a lie. (Link explaining it or not).

Explain it right on the page if you're going to put false information on the web.

The problem with the so-called explanation Answers in Genesis returned is that AiG is attempting to mislead people to believe these articles were written back in 1994.

Addendum 2 (4 January 2002)
Some evolutionists have tried to counter this paper by charging me with faking the information presented. There is no deceit (faking), or contradiction, in the article. As stated at the beginning of the article, the article on the web was originally
published in Creation Ex Nihilo Technical Journal (now simply [home/area/magazines/technical.asp ]TJ) in 1994,

What Sarfati is neglecting to tell people, is that in 2001, when he wrote the article:
http://www.answersingenesis.org/pbs_nova/0926ep2.asp he knew Ambulocetus' spine, leg and pelvis bones had been recovered five years before!

So, what does out of date information from way back in 1994 have to do with the information that was available to Sarfati in 2001, when he wrote this article addressing Evolution: Great Transformations a program which aired in 2001. Sarfati may very well have known about the recovery of Ambulocetus' pelvis, leg and backbones in 1996, but he rejected the information out of hand, and continued to refer to a journal from 1994, on purpose and that was to deceive visitors to their website. Answers in Genesis / Jonathan Sarfati would like to freeze the year 1994 in a bottle, and continue to reject the fossil recoveries made by Thewissen in 1996.

That sums up the problem.

Answers in Genesis deals with the issue by sending a URL which has nothing to do with the article located at:
http://www.answersingenesis.org/pbs_nova/0926ep2.asp

The problem I have with what AiG has done, is about ethics and standards in the scientific community.


Webmaster note:

Joe: "Is there a photograph available (not "an approximate computerised reconstruction, based on the fossil remains that do exist" as per image label) of a single complete Ambulocetus fossil in-situ? i.e. A complete fossil skeleton recovered from a single, non vertically or horizontally dispersed locus. This would end conjecture on the correct morphology.

Webmaster: How very sad that you have became confused by the image. Yes, it should have been made more clear.

Actually, this photograph is what you are viewing:

The REAL Photo :

What you are looking at, is in fact, the complete skeleton (at least theoretically using computer technology, in the "approximate computerised reconstruction, based on the fossil remains that do exist"). Emphasizing: the remains that DO EXIST. Utilizing Photoshop, and erasing all pixels of the Professor and laboratory and leaving ONLY the Ambulocetus natans fossil. Then, to provide a symmetrical reconstruction of what ambulocetus *should look like* by filling in, with a mirror image of the leg and arm bones that already exist.

Cetacean Evolution (Whales, Dolphins, Porpoises)

Evidence Of Common Ancestry of Cetaceans and Certain Species of Land Mammals

by Edward T. Babinski

(Reviews of several creationist articles that deny such evidence exists.)

REVIEW OF A Whale of a Tale? (Ambulocetus) Don BattenThe author states, ". ..there is no evidence [in Ambulocetus] of the development of the horizontal tail flukes so characteristic of whales." Evolutionists don't expect Ambulocetus to have had tail flukes: "Unlike modern cetaceans, Ambulocetus had a long tail and thus probably lacked a tail fluke."
(Thewissen, Science, January 1994, p. 211)
See this link.

(Neither does the cartilage which constitutes the tail flukes of whales preserve as well as bone does.)
Since we are talking about the tail of Ambulocetus let me add a "review within a review" of another creationist article whose author stated, "The tail movements [of the earliest whales] would begin to crush its reproductive apparatus against its pelvis. This would have a tendency to lower the animal's sexual urges somewhat and it would soon lose interest in reproduction -- not a very positive evolutionary step. Taken to extremes, this new tail movement would simply crush the whole pelvis. The selective pressures of the environment, or natural selection, would work against any such change of tail on a land-dwelling mammal."

This "tail swinging" argument is from 1984 when Gish used to show his slides of a cow evolving into a whale, calling it an "udder failure" (Gish, 1985). But even back in 1984 biologists knew that " . . . the giant river otter Pteronura) of South America possesses a horizontally widened tail that produces thrust, even though the caudal vertebrae are of a typical terrestrial form (Fish, 1998)." And the river otter hasn't become extinct yet. "Furthermore, the swimming method of these otters (dorso-ventral undulation of the vertebral column) makes a very good analogy for the swimming method of Ambulocetus. (Thewissen, 1998)."

"It is known from the fossil record that in Ambulocetus, the toes are elongated and the femur is short. The other skeletal elements are no different than other land mammals (Thewissen, et al, 1994) . . . .In the earliest known protocetid, Rodhocetus, there are . . . a further reduction of the femoral length, the rearward migration of the nares (nasal bones), to above the canine teeth (this is true of Rodhocetus, but in Ambulocetus, the narial region is still unknown), the sacral vertebrae are unfused, although they still articulate fully with the pelvis, a shortening of the cervical (neck vertebrae), and probably the most important, are the changes in the caudal (tail) vertebrae. In Rodhocetus the tail vertebrae are relatively shorter, thicker, and more massive than those of land mammals, allowing for better attachment for the muscles involved in powering the, very likely, recently evolved flukes (Gingerich, et al, 1994)."

REVIEW OF A Whale of a Tale? (Ambulocetus) Don Batten(Continued) The author states, "There is no evidence of. . . the unique hearing system of whales (i.e. with no opening to the exterior)." But "Ambulocetus had whalelike skull characteristics that are found in the Archaeocetes ["early whales"], including an ectotympanic with a large sygmoid process, a reduced zygomatic arch, a wide supraorbital process and a narrow muzzle. While these characteristics may also be present in the terrestrial Mesonychids, Ambulocetus also possessed the small protocones and large accessory cusps which distinguish the whales from the Mesochynids."
See this link.

(Apparently the author is unaware of the fossil data and research concerning the earbones of Pakicetus and other early whales.) The author states, "There is no evidence of. . . the blow-hole." No evolutionist expects Ambulocetus to have had a blowhole. The earliest known whale, Pakicetus, had nostrils near the tip of its snout. Ambulocetus we don't know about, but wouldn't expect it to have had a blowhole because even Rodhocetus (more adapted for the water) had no blowhole, though it did have nostrils that were moved back from the front to a place above the canine teeth. Later on we see that Basilosaurus's nostrils were in the middle of its snout, still only halfway toward its head. Even Eocetus and similar "archeocete whales" of the late Eocene that have lost their hind legs entirely, still retained a "primitive" whale's skull and teeth, and unfused nostrils.

REVIEW: A Whale of a Tale? (Ambulocetus) Don Batten
(Continued) The author states, "The robustness of the femur, and presence of hooves confirm the creature as a land animal." "Land animal?" Look at the pic and consider the size of the creature in relation to the length of its arms and legs, especially its shortened forearms, and the way its femur is relatively short compared with that of land animals. And notice how long its fingers and toes were! Seems more adapted to swimming than walking/running on land, though it probably spent time on land. Even crocodiles with their short arms and legs spend time on land, but I wouldn't call them strictly "land animals." As for Ambulocetus's "hooves," it is true that it had long fingers that ended with tiny hooves on each one but that confirms yet another link between the earliest whale-like mammals and the Family Mesonychidae which was the same Family that Pakicetus belonged to.

Zimmer and Gingerich are talking about the tympanic. (below) Both are earbones, but they are different.

"One particularly baffling fossil was the back part of a 50-million-year-old skull. It was about the size of a coyote's and had a high ridge running like a mohawk over the top of its head, where muscles could attach and give the mammal a powerful bite. When Gingerich looked underneath the skull, he saw ear bones. They were two shells shaped like a pair of grapes and were anchored to the skull by bones in the shape of an S. For a paleontologist like Gingrich, these ear bones were a shock. Only the ear bones of whales have such a structure; no other vertebrate possesses them."

REVIEW OF The Overselling of Whale Evolution
by Ashby L. Camp
The author complains about the dating scheme of the Archaeocetes (early whales): "In the standard scheme, Pakicetus inachus is dated to the late Ypresian, but several experts acknowledge that it may date to the early Lutetian. [18] If the younger date (early Lutetian) is accepted, then Pakicetus is nearly, if not actually, contemporaneous with Rodhocetus, an early Lutetian fossil from another formation in Pakistan.[19] Moreover, the date of Ambulocetus, which was found in the same formation as Pakicetus but 120 meters higher, would have to be adjusted upward the same amount as Pakicetus.[20] This would make Ambulocetus younger than Rodhocetus and possibly younger than Indocetus and even Protocetus.[21] In the standard scheme, Protocetus is dated to the middle Lutetian, but some experts have dated it in the early Lutetian.[22] If the older date (early Lutetian) is accepted, then Protocetus is contemporaneous with Rodhocetus and Indocetus. In that case, what is believed to have been a fully marine archaeocete was already on the scene at or near the time archaeocetes first appear in the fossil record. [23] "The fact that all of the above critters are clustered together in geologic time with similarly shaped skulls and intermediary earbones unlike modern day whales, and that they were all mammals adapted in varying degrees to a water habitat, and that they all preceded modern cetaceans, speaks louder than the author's reliance on dating haggles to make a case for creationism. Reminds me of the old joke about two men looking up at a tall skyscraper and arguing vehemently over whether it was exactly one hundred stories tall or one-hundred-and-one stories tall by each of their careful reckonings. Then a third man comes over, in this case the author of the above article, and argues that their disagreements prove that his hypothesis -- that the building is really only a SINGLE storey tall -- makes more sense.)

"It's tempting to build this story like a totem pole, with trotting Pakicetus at the base, Ambulocetus laying its humming jaw on top of it, and Rodhocetus, the earliest whale to swim like a whale, sitting above the two. It seems like such a smooth progression toward today's cetaceans that it must be right. But such a version would only be a vertical slice of the story. Life doesn't proceed from one point to another -- it forks and radiates like the cladograms that represent it. Paleontologists have found many other whale bones in Eocene rocks of Pakistan and India. Mostly they are teeth -- the rock surrenders a few skulls as well -- but even teeth clearly show that their owners were not clones of Pakicetus or the other better-known whales. Ambulocetus kept to brackish deltas and coastal water, but Thewissen has found whale teeth from about the same age in what at the time was the open ocean. Gingerich has found at least three contemporaries of Rodhocetus a few million years younger than Ambulocetus: Takracetus, with a wide, flat head; Gavinocetus, with a slender skull and loose hips; and Dalanistes, a whale with a head as long and narrows as a heron's set on a long neck, with hips cemented firmly enough to its spine to walk on land. If this is a confusing picture, it should be. As time passed, certain whale species emerged that were more and more adapted to life in the water, but other species simultaneoulsy branched away in many directions. Walking and swimming whales lived side by side, or in some cases traded homes as the buckling birth of the Himalayas shuffled their habitats. Some were only a minor variation on a theme that would carry through to modern whales, but others -- heron-headed Dalamistes, for example -- belonged to strange branches unilke anything alive today. "-- Carl Zimmer, At the Water's Edge

QUESTION: How did the whales's eco-location system evolve?
ANSWER: There is a fascinating discussion of what is presently known about the evolution of whale skulls and of cetacean eco-location in Carl Zimmer's book, By the Water's Edge.

QUESTION: How did whales evolve a process whereby the young whale could ingest milk from the mother through a water-tight sealed apparatus with the milk being pumped into the young whale instead of them having to suck by some type of random, evolutionary process?
ANSWER: "Randomness" does not phase atheistic evolutionists (who view natural selection as non-random), nor does it phase theistic evolutionists nor Intelligent Design advocates (for whom the evolutionary process is not random), yet who all agree that evidence for common ancestry exists. The fact that female whales birth their young and feed them via mammary glands reminds evolutionists that whales share their ancestry with mammals.

Ambulocetus as a Fossil Transitional by Lenny Flank (a response to Gish's analysis of Ambulocetus)

Introduction to the Cetacea (with links to Cetacean evolution sites at the bottom of the page)

The Evolution of Large Complex Brains Over Geological Time is Not Unique to the Human Species. It Has Now Been Documented in the Evolutionary Line of the Cetacea As Well
A new Emory University study (Release date: Oct. 22, 2004) maps how brain size changed in dolphins and their relatives the past 47 million years, and helps to provide some answers to how cetacean species evolved increasing encephalization (just as the primate line leading to human beings also evolved increasing encepahlization). Increasing encephalization over time is not a phenomenon unique to the human species and lineage.
Marino and her colleagues spent four years gathering the data and tracking down fossils at The Smithsonian Institution and other museums. A total of 66 cetaean fossil crania were scanned and measured. This subset was added to brain and body weight data from 144 modern cetacean specimens for a total sample of 210 specimens representing 37 families and 62 species. Their work produced the first description and statistical tests of the pattern of change in brain size relative to body size in cetaceans over 47 million years. They found that encephalization level increased significantly in two critical phases in the evolution of odontocetes. "[Modern] dolphin brains are four to five times larger for their body size when compared to another animal of similar size. In humans, the measure is seven times larger -- not a huge difference. Essentially, the brains of primates and cetaceans arrived at the same cognitive space while evolving along quite different paths" Marino says. "What the data say to me is that we, as humans, are not that special. Although we are highly encephalized, it's not by much or for that long compared with odontocetes." "A description of the pattern of encephalization in toothed whales has enormous potential to yield new insights into odontocete evolution, whether there are shared features with hominoid brain evolution, and more generally how large brains evolve," Marino says. Marino's previous research has shown how dolphins have the capacity for mirror self-recognition, a feat of intelligence previously thought to be reserved only for Homo sapiens and their closest primate cousins.
