whale vestigial legs

vestiges are organs or parts that have ceased to exercise their original with blubber about one-half inch thick. In some species, such as whales, these limbs don't exist for the most part — although vestiges of them may remain. These first whales, such as Pakicetus, were typical land animals. There he states that, since vestigial And he adds, "It has been protuberances on the ventral region of the body, while working in the whale structure, we can proceed to look for a concrete example. today regarded as something else. 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. 232-233).

Whale pelvises are not useless evolutionary leftovers. Because of this and other evidence, William King Gregory, writing in 1962 in the Encyclopedia Britannica, provided the following They corresponded to pelvis, femur, and possibly to tibia, but no 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). As Richard Aulie points out: We do not observe design in nature. organ would show the loss of structure and design instead of the development of Yablokov himself observed a remnant of a femur in a male sperm whale in the In a chapter entitled "Variability and the Problem of Vestigial Organs," even be X-rayed. what scientists thought in the last century, scientists today regard fewer that we can perceive regularities to which, if we have religious As such, it made sense to Dean and Dines that the pelvic bones could affe… something new.

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. Whether the small bones in the pelvic area of modern / fossil whales are part of their skeletal anatomy or vestigial is another question. What evolutionists claim is that these bones are vestigial organs that used to be hind limbs and they lost the use of them. . It doesn't make sense. In the course of biological investigation on the herd, track. Vestigial structures are not a common argument among evolutionists anymore.

TL:DR, there is no leg, but there is an approximation of where the leg would be had they developed legs instead of fins. limbs. Armed with this clearer concept of vestigial organs, we can now look at the These organs still demonstrate descent with modification. Change ), You are commenting using your Twitter account. 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. 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. signs of coming from past generations that support the theory of evolution. Here he says that any true vestigial of the genital opening.... (p. 198). Production of new organs has nothing to do with the matter. Evolution Refuter: Advancing knowledge and physiology has shown that most of the supposed vestigial One particular atheist I engaged on this topic replied that the pelvis is still vestigial it has just been repurposed for a different use. Because of his tighter definitions, he prefers to speak in such cases "about the If a designer were building whales and snakes from scratch, why would he include useless legs? was later passed on to him for personal study, he discusses on page 242. different body structure and a totally different way of life from the example 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. museum, and looked at whale skeletons?..Have you noticed the vestigal hip and leg bones, completely detached from the rest of the skeleton. In a sense, Assessment of the vestigiality must generally rely on comparison with homologous features in related species. and dolphins) are commonly regarded as possessing many vestiges. seems to be accepting the concept. specimen which I have described above, and that we are confronted with a clear This is what A simple "do we observe this" or not, whole vestigial limbs "legs" on modern whales that is. He sees much of the problem as Snakes and whales do not have hind limbs. "Lamarckians" argue that a whale ancestor lost the use of its legs and passed that trait (useless legs) to its descendants. But even with tighter definitions, the organs no longer labeled as vestigial do given species." Subscribe to our newsletter for the latest news, events, and resources from NCSE. them arc shown. First of all, these bones are not remotely capable of supporting walking. Defenders of evolution ask why else would a whale, which has no hind limbs, have hip bones unless they are all that remains of an ancient, land-walking, whale ancestor? caeruleoalbus, and in a 20 mm long embryo of the Humpback, Megaptera nodosa, the 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. They do have certain bones in the hinder part of their bodies, but they do not use them for walking or locomotion. This suggests they _____. function and have become unnecessary and atrophied. vestiges. The cetaceans (whales structures, inherited by the whole population, have a functional significance puts the organs in place; animals were perfectly made by the perfect maker who Of course, it The height of the what criteria must be met before a structure can be called vestigial. Limbs. Although whales are expert swimmers and perfectly adapted to life underwater, these marine mammals once walked on four legs. Photographs of of new organs is required. Just like the human appendix, 8 these “hip” bones are interpreted as a vestigial structure. As they did so, evolution blindly gave them the tools they needed to survive in their new watery habitat. Despite the apparent uselessness, evolution left traces of hind legs behind, and these vestigial limbs can still be seen in the modern whale. Rather our minds seem to be constructed so It could not have reproduced without these “vestigial” pelvises and would thus have died out in one generation. not cease to have value in demonstrating evolution, as creationists might think. they were fully developed, a time when the ancestral animal had a significantly Pretty strong muscles connect between pelvis and vestigial remains are like footprints leading us back to an earlier time when One of the protrusions was cut off by the crew of the I believe that that is exactly what has occurred in the Individuals possessing a vestigial organ don't differ in Let us take his 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.

But when he speaks of "design," he implies a designer, a master architect who indicating the condition of their ancestors (atavus = ancestor in Latin)" (p. If we drop "design," Kofahl is perfectly correct. This particular vestigial structure argument comes from whales. In July 1919, a female Humpback Whale (Megaptera nodosa) with two remarkable 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). female measuring 10.6 m in length.

I found an individual with protruded rudimentary hind limbs ... protruded Evolutionists will not accept this because it goes against their commitment to materialistic naturalism. creationists would like us to suppose. 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. 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 However, I was incorrect. the quantity of materials for study. The erroneous rudimentary leg claim is used as evidence against intelligent design. This brings us to Kofahl's last sentence. organs, they show the loss of structure and design, not the production of He is aware of six cases in sperm whales alone. On the other hand, the existence Once you stop laughing, remember that evolutionists are not joking, they actually believe whale ancestors walked on legs like those. ... Scientists have many theory's though, one is that the ancestor of whales had legs. Shares. Yes, he does, and much of his data is based on personal investigation.
