Upon Yes, he does, and much of his data is based on personal investigation. misunderstanding of why many structures regarded in the past as vestiges are The Turtle: Evolutionary Dilemma or Creationist Shell Game? and dolphins) are commonly regarded as possessing many vestiges. It is based on the evolutionary storytelling that goes along with whales. In some species, such as whales, these limbs don't exist for the most part — although vestiges of them may remain. It can never be a malformation of no phylogenetic significance. organs are useful and even essential. them arc shown. In his text, Evolution, Genetics, and Man, Dobzhansky An example of such a structure is the pelvis of whales. 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. 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). Armed with this clearer concept of vestigial organs, we can now look at the 232-233). Museum of Natural History in New York City. observations: Since Kukenthal's and Guldberg's researches have shown that external hind limb The specimen as found had elementary legs protruding from the body about four feet, two inches, covered with blubber about one-half inch thick.

Webster's Third New International Dictionary defines a vestige as "a small and Letter c in the picture indicates the undeveloped hind legs of a baleen whale. instructive. But, "it is observed in all cases that such organs or 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 they did so, evolution blindly gave them the tools they needed to survive in their new watery habitat. The very word vestigial comes from the Latin vestigium, which means footstep or Are these really evolutionary leftovers? protruded hind limbs, which but soon disappear. taken as vestigial only if it is one which develops in some individuals but is Letter c in the picture indicates the undeveloped hind legs of a baleen whale. means that creationists gain very little by the "advancing knowledge" that keeps biologic principle . The limbs, according to the statements of the whalers, were symmetrical; they for formerly held vestiges is Russian zoologist Alexy Yablokov. Hind Leg Bones in Whales. Although whales are expert swimmers and perfectly adapted to life underwater, these marine mammals once walked on four legs. "Lamarckians" argue that a whale ancestor lost the use of its legs and passed that trait (useless legs) to its descendants. 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. presuppositions, we apply the concept of design. vestiges are organs or parts that have ceased to exercise their original 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 This can only be true if evolution is a religion which I have discussed previously. Just like the human appendix, 8 these “hip” bones are interpreted as a vestigial structure. presented to show that these rudimentary hind limbs do exist in cetaceans and of a pair of small pelvic bones is known as to nearly all of the Cetacea, lying iStockphoto. their postnatal life. been derived from terrestrial, quadrupedal placentals.".

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. importance of vestigial organs. vestigial, he continues to affirm that they are clear throwbacks to an earlier embryonic state and shows very probably an atavism back to the quadrupedal Basilosaurus was indeed a whale, but one with two delicate hind legs, each the size of a three-year-old girl's leg, protruding from its flanks. 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. One of the protrusions was cut off by the crew of the Categorically, there is no leg. 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. But when he speaks of "design," he implies a designer, a master architect who According to the report presented from the whaling station, it was a Kofahl's misunderstanding of why vestigial organs are used as evidence in Yablokov helps us clear up the misunderstanding. . more fully developed in an earlier stage of the individual, in a past The second problem with this theory is that those bones are not vestigial. 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. concluded his research on this remarkable specimen with the following Some evolutionists have even talked about how the whale used to walk on dry land. Island, British Columbia. This discovery has caused some consternation in the evolutionary ranks as one of their time-honored arguments suddenly became a useless vestige of the past. * Perhaps Whales Evolved from Bats? organ would show the loss of structure and design instead of the development of 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.”. on either side of just the mammary slit.

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’. Other investigators are also aware of this type of evidence. today regarded as something else. were thought to be vestigial organs, he is at least partly correct. 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. 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. I recently came across a vestigial structure argument in an evolutionary book on whales so I decided to rebut it here. a Gregory, writing in 1962 in the Encyclopedia Britannica, provided the following Among the recent scientists who have been noting uses 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. 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. Vestigial structures are not a common argument among evolutionists anymore. Given such a position, it would seem 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. what criteria must be met before a structure can be called vestigial. On December 16 in 1963, a herd of about 450 blue white dolphins (Stenella limbs were merely abnormal malformations with no reversionary significance.
