Being vestigial, they point to an earlier stage of concluded that: ... in my opinion the disappearance of the paired hind limbs in the Cetacea It can never be a malformation of no phylogenetic significance. joints exist between them. From the outside, they don't look much like whales at all. The very word vestigial comes from the Latin vestigium, which means footstep or These vestigial structures disprove Paley's theory of Natural Theology. protuberances on the ventral region of the body, while working in the whale The protuberances were present on both sides Whether the small bones in the pelvic area of modern / fossil whales are part of their skeletal anatomy or vestigial is another question. Hind Leg Bones in Whales. Even assuming that they are vestigial legs, that tells us nothing about what those legs were used for (if anything); that doesn't tell us that whales once walked (or jumped, or kick-boxed, or rode bicycles). Baleen whales can have streamlined or large bodies, depending on the feeding behavior, and two limbs that are modified into flippers. Even if a structure currently has an unknown function, much like the appendix or the whale pelvis once did, that does not imply it is a vestige. The limbs, according to the statements of the whalers, were symmetrical; they I’m confident that eventually, science will find a use for any few remaining vestigial structures left, only deepening the evolutionists hole they have dug for themselves. Just try to imagine the whale walking on them. Whales have vestigial legs.

Categorically, there is no leg. They have a definite function. That is what we have discovered in the case of the cetaceans. . They were considered vestigial leftovers, like our tailbones and appendices. From the beginning, creationists have disputed either the existence or The emergence of vestigiality occurs by … concept that has no usefulness in science. specimen which I have described above, and that we are confronted with a clear are truly vestigial. flukes in the cetacean embryos. Often, seemingly minor features provide critical evidence to link animals that are highly … Limbs. What evolutionists claim is that these bones are vestigial organs that used to be hind limbs and they lost the use of them. Just try to imagine the whale walking on them. Although whales are expert swimmers and perfectly adapted to life underwater, these marine mammals once walked on four legs. been derived from terrestrial, quadrupedal placentals.". fitness from those without it. An Email Exchange Regarding “Vestigial Legs” Pelvic Bones in Whales by Jim Pamplin Excerpt: The pelvic bones (supposed Vestigial Legs) of whales serve as attachments for the musculature associated with the penis in males and its homologue, the clitoris, in females. their postnatal life. were thought to be vestigial organs, he is at least partly correct.

Assessment of the vestigiality must generally rely on comparison with homologous features in related species. puts the organs in place; animals were perfectly made by the perfect maker who A: Not all textbooks cite the same vestigial structures, but let’s take a look at all of them together, and then analyze each one separately. Yes, he does, and much of his data is based on personal investigation. Their rescuing device of choice for the “vestigial” whale pelvis is particularly curious. But to support the theory of evolution, evidence for the production If indeed the whale pelvis is a repurposed vestige, evolution has a problem. Variability of Mammals, discusses the important functions played by the pelvic organ present in the works of Darwin ..." (pp. According to the evolution story, whales were originally land animals. indicating the condition of their ancestors (atavus = ancestor in Latin)" (p. does Yablokov find any evidence for true vestigial structures in the cetaceans? Webster's Third New International Dictionary defines a vestige as "a small and operating from the whaling station at Kyuquot, on the west coast of Vancouver REVIEW OF "The Strange Tale of the Leg on the Whale" by Carl Wieland. (p. 207). And he adds, "It has been This can only be true if evolution is a religion which I have discussed previously. Jerry Coyne from the University of Chicago sums up the evolutionary position nicely: Whales are treasure troves of vestigial organs. Whale," was published in June 1921. These bones The whale had to have been designed the way we find it. Oakland, CA 94612. The muscles most frequently claimed to be vestigial in man are the auricular muscles of the ear, the erector pili muscles of hair follicles, and the plantaris muscle of the calf of the leg. of the genital opening....

As Richard Aulie points out: We do not observe design in nature. Predictably, rather than abandon their dogma, they lept at a rescuing device. Those Amazing Animals: The Whales and the Dolphins. deeply buried under the skin, causing no protuberance on the body surface. A simple "do we observe this" or not, whole vestigial limbs "legs" on modern whales that is. Because of this and other evidence, William King The difference between the two cases is never essential but rather a problem of In the course of biological investigation on the herd, known for a long time that such organs exist in animals.". for formerly held vestiges is Russian zoologist Alexy Yablokov. protuberance was 5.35 cm on the right side and 6.56 cm on the left side. alive today. Does this signify that, given enough time, scientists will soon find uses for Of course, it Just like the human appendix, 8 these “hip” bones are interpreted as a vestigial structure. evolutionary development. The tail-powered swimming of modern baleen (Mysticeti) and toothed (Odontoceti) whales evolved from the … Evolutionists love the vestigial structure argument. The evolutionist position is at once simple and perfectly logical: modern whales have vestigial legs and pelvic girdles precisely because they evolved from land animals with legs (most likely artiodactyls, an ungulate mammal of which hippos are perhaps the best modern example). 1904 Franklin Street, Suite 600 knew exactly what was to be done. is to reduce the need to interpret biologic processes * Perhaps Whales Evolved from Bats? . 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. track. But when he speaks of "design," he implies a designer, a master architect who Other investigators are also aware of this type of evidence. In fact, the peer-reviewed journal Evolution published an article in 2014 which emphatically stated that the “vestigial pelvis” of whales is actually the anchor point for some very important reproductive muscles. Despite the apparent uselessness, evolution left traces of hind legs behind, and these vestigial limbs can still be seen in the modern whale… requires "evidence for the production of new organs...." This sentence shows something new. The height of the Upon ( Log Out /  As he states on page 240, "The structure of these organs was A: Not all textbooks cite the same vestigial structures, but let’s take a look at all of them together, and then analyze each one … So we must ask, However, according to evolutionary dogma, because evolution is a blind unguided process, it missed a few things, leaving behind a pair of vestigial pelvises in whales. In a sense, There's no question that some whales have these structures. Many living species have a vestigial pelvis and leg bones, testifying…to their descent from four-legged ancestors. The picture below on the left shows the central ankle bones (called astragali) of three artiodactyls, and you can see they have double pulley joints and hooked processes pointing up toward the leg-bones. Gregory, writing in 1962 in the Encyclopedia Britannica, provided the following station. Shares. First of all, these bones are not remotely capable of supporting walking. Evolution Refuter: Advancing knowledge and physiology has shown that most of the supposed vestigial TL:DR, there is no leg, but there is an approximation of where the leg would be had they developed legs instead of fins. on either side of just the mammary slit. This suggests they _____. The pelvis would have needed to immediately transform into an anchor for reproductive muscles in the first generation of whales that went into the water. were found. Figure \(\PageIndex{1}\): Whale Skeleton: The pelvic bones in whales are also a good example of vestigial evolution (whales evolved from four-legged land mammals and secondarily lost their hind legs). However, as science advanced, vestigial organs were slowly all discovered to have a function. They corresponded to pelvis, femur, and possibly to tibia, but no All tetrapods (including whales) have pelvic bones. It is based on the evolutionary storytelling that goes along with whales. If a designer were building whales and snakes from scratch, why would he include useless legs? 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. Yet evolutionists insist the whales transitioned gradually into water animals from land animals. In July 1919, a female Humpback Whale (Megaptera nodosa) with two remarkable Museum of Natural History in New York City. Of course, these bones are generation, or in closely related forms." To Yablokov, an organ should be Whales have vestigial legs. Gregory concluded in his Encyclopedia Britannica article, "that the Cetacea have Their land-dwelling ancestors lived about 50 million years ago. having been caused by "vague definitions of the concept of vestigial organs," embryonic state and shows very probably an atavism back to the quadrupedal Are these really evolutionary leftovers? The specimen as found had elementary legs protruding from the body about four feet, two inches, covered with blubber about one-half inch thick. It has vestigial organ is indeed an organ that has lost its original structure. ", Needless to say, no protrusion of the hind limb is seen in all the Cetacea in Armed with this clearer concept of vestigial organs, we can now look at the are in the exact position in which the hind limb rudiments have been found in iStockphoto. What Is a Vestigial Structure? examples of atavism, "organs appearing in the development of present forms and Borisov observed a sperm whale with well-developed what scientists thought in the last century, scientists today regard fewer Change ), Another “Return to Water” Story – In His Image, Resource Review: The Greatest Hoax on Earth – In His Image. not characteristic of the whole population (p. 241). protrusions on the ventral side of the body, posteriorly, was captured by a ship Only in the early embryonic stage they show a pair of legs protruding from the body about four feet, two inches, covered To speak to the statement by Kofahl, then, seems to be in order. and logically cannot be named as vestigial." protruded hind limbs, which but soon disappear. organs, they show the loss of structure and design, not the production of seems to be accepting the concept. I believe that that is exactly what has occurred in the come to the conclusion that the protrusions actually do represent vestigial hind Japan, a pair of budlike vestigial hind limbs were present. entirely separate evolutionary issue. But "design" is a For example, when Yablokov denies that pelves and whiskers in whales are truly far apart from the vertebral column on both sides of the genital opening. Do whales have leg ‘genes’ Published: 27 June 2020 (GMT+10) Joshua S. wrote to us asking if it is true that whales have ‘leg genes’.

In June 1962, V. 1. limbs and show a remarkable reversion to the primitive quadrupedal condition. Compared to Essentially it allows them to argue that there is no Creator because the vestigial structures are junk and a good God would not create junk. Below on the right is a … These are sometimes claimed to be vestigial legs, but according to whale expert Philip Gingerich, the “Hind limbs of Basilosaurus are most plausibly interpreted as accessories facilitating reproduction. Some evolutionists have even talked about how the whale used to walk on dry land. His purpose is to A simple "do we observe this" or not, whole vestigial limbs "legs" on modern whales that is. Vestigiality is the retention during the process of evolution of genetically determined structures or attributes that have lost some or all of the ancestral function in a given species. Once you stop laughing, remember that evolutionists are not joking, they actually believe whale ancestors walked on legs like those. nonfunctional as well as uncharacteristic of the whole population. The argument usually is framed as follows: “Vestigial structures, such as the rudimentary pelvis of snakes and whales … are extremely puzzling if organisms are rationally designed” by an intelligent designer. On the other hand, leading scientists, such as the late zoologist and Hind Leg Bones in Whales. Vestigial structures are not a common argument among evolutionists anymore. impossible that these vestigial organs should continue their growth and persist The specimen as found had elementary up the vestigial-organ argument as a case that is doomed? Furthermore, to make of design vestigial organs is that they were organs "present in all the individuals of a . museum, and looked at whale skeletons?..Have you noticed the vestigal hip and leg bones, completely detached from the rest of the skeleton.

Given such a position, it would seem until the adult stage. He It simply means there is research yet to be done. In the catalogue of purported vestigial parts, whale hips are "the marquee example," writes Stephanie Keep at the absurdly named "Science League of America" blog populated by our Darwin-lobbying friends at the National Center for Science Education. In Yablokov's view, the problem with most of the previously held examples of pelvis, and in the right whale even the tibia exists. flukes of them. This is an 244). Q: Biology textbooks say there are vestigial structures like…(a) human tail bones, (b) whale pelvis, (c) snake hind legs, (d) the appendix, and (e) gill slits on embryos. means that creationists gain very little by the "advancing knowledge" that keeps seems to have an intimate causal nexus with the appearance of the paired caudal presented to show that these rudimentary hind limbs do exist in cetaceans and In some species, such as whales, these limbs don't exist for the most part — although vestiges of them may remain. $\endgroup$ – John May 17 '12 at 15:47 embryonic Megaptera; there are strong indications that the cartilaginous femur At the request of Roy Chapman Andrews, the skeletal remains, which consisted What is questionable is the interpretation of what, exactly, they are. and metatarsal, the cartileges as femur and tarsus, and published his findings: After studying the material and discussing it with various scientists, I have misunderstanding of why many structures regarded in the past as vestiges are (p. 131), In 1957, Tezio Ogawa and Toshiro Kamiya, writing in the same journal, reported condition of the whale's remote ancestors. These examples of rudimentary hind limbs meet Yablokov's criteria of being This This is flatly absurd. I recently came across a vestigial structure argument in an evolutionary book on whales so I decided to rebut it here. Hats off to your work in showing the flaws of evolution!

Among the recent scientists who have been noting uses (p. 135), Other vestigial reports on sea mammals could be cited, but enough has been disappearance of the hind limb elevation with the first appearance of the caudal femur, while two weak muscles are extended between femur and tibia... . organ would show the loss of structure and design instead of the development of Because of his tighter definitions, he prefers to speak in such cases "about the This could not have happened gradually. Yablokov considers them caeruleoalba) was caught by fishermen at Kawana Beach in the eastern coast Assessment of the vestigiality must generally rely on comparison with homologous features in related species. The cetaceans (whales I found it bitingly ironic that the same atheist who stated that the whale pelvis is a vestigial structure ended our conversation by saying I was “living in denial.”. Vestigial organs are traces of organs previously functional. different body structure and a totally different way of life from the example with blubber about one-half inch thick. function and have become unnecessary and atrophied. Without the presence of those useless leftovers, whales would be totally unable to reproduce.

The second problem with this theory is that those bones are not vestigial. One of these protuberances could In the limbs were merely abnormal malformations with no reversionary significance. The fin whale is the fastest baleen whale, recorded swimming at 10 m/s (36 km/h; 22 mph). was attached to the pelvic elements. To illustrate, there is an image below with the bones that are purportedly vestigial legs circled. These first whales, such as Pakicetus, were typical land animals. Unfortunately whale hips have now gone the way of appendix. If it had not done so, the first whales could not have reproduced and would have gone extinct in one generation. This particular vestigial structure argument comes from whales. Now, how would a creationist explain this.. Andrews identified the bones as tibia instructive. Pretty strong muscles connect between pelvis and organs as truly vestigial. "Lamarckians" argue that a whale ancestor lost the use of its legs and passed that trait (useless legs) to its descendants. One of the protrusions was cut off by the crew of the These organs still demonstrate descent with modification. of new organs is required. The report, entitled "Remarkable Case of External Hind Limbs in a Humpback importance of vestigial organs. Promiscuous Whales Make Good Use of Their Pelvises Hips don’t lie: Whale pelvic bones are not vestigial but instead evolved to help the marine mammals maneuver better during sex structures, inherited by the whole population, have a functional significance vestiges. It could not have reproduced without these “vestigial” pelvises and would thus have died out in one generation. This brings us to Kofahl's last sentence. (p. It doesn't make sense. Vestigiality is the retention during the process of evolution of genetically determined structures or attributes that have lost some or all of the ancestral function in a given species. When Kofahl says that advancing knowledge has discovered uses for most of what Professor Andrews had sufficient anatomical reasons to reject the idea that the was later passed on to him for personal study, he discusses on page 242. Now, how would a creationist explain this.. His book, Baleen whales use their baleen plates to filter out food from the water by either lunge-feeding or skim-feeding An example of such a structure is the pelvis of whales. the quantity of materials for study. Vestigial Structure: deff: A rudimentary or degenerate, usually non functioning, structure that is the remnant of an organ or part that was fully developed or functioning in a preceding generation or an earlier stage of development. proclaim the fact of evolution.". Speaking of vestigial features, one of my favorite examples with whales and snakes is the manatee / sea cow / dugong. factory at Skalistii (Central Kuril Islands). Far more significant than the best evidence claimed for the famed Indohyus to be the land-dwelling ancestor of the whale, i.e, it's "thickened knob of bone in its middle ear", is the identical echolocation sequences in bats and whales (see Li, et al., 2010, Current Biology)!One wonders … Island, British Columbia. 232-233).

Kofahl's misunderstanding of why vestigial organs are used as evidence in not cease to have value in demonstrating evolution, as creationists might think. I wanted to ask: Is there any truth to the claim that whales possess genes for hind legs but are not expressed or are dormant in whales. It is those vestigial organs that show second sentence in Kofahl's statement. modified by a significant change in function at some time in their evolution." Limb in the Cetacean Embryos" in The Scientific Report on Whales Research, However, their skulls particularly in the ear region, which is surrounded by a bony wall strongly resemble those of living whales and are unlike those of any other mammal.

Most evolutionists have abandoned the human vestigial structure argument and I was under the impression that vestigial structures had pretty much become a vestige of evolutionary past. vessel but the other was photographed in situ by the superintendent of the Extinct whales do not evolve. Whether the small bones in the pelvic area of modern / fossil whales are part of their skeletal anatomy or vestigial is another question. Like a lot of evolutionary arguments, this one falls apart upon closer inspection. The Turtle: Evolutionary Dilemma or Creationist Shell Game? William King organs show a loss of structure, they don't help evolution, since evolution Letter c in the picture indicates the undeveloped hind legs of a baleen whale.
