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. 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. It can never be a malformation of no phylogenetic significance. discovering useful, but altered, functions for organs formerly defined as That is what we have discovered in the case of the cetaceans. To illustrate, there is an image below with the bones that are purportedly vestigial legs circled.

Despite the apparent uselessness, evolution left traces of hind legs behind, and these vestigial limbs can still be seen in the modern whale. These vestigial structures disprove Paley's theory of Natural Theology. Shares. limbs were merely abnormal malformations with no reversionary significance. entirely separate evolutionary issue. embryonic state and shows very probably an atavism back to the quadrupedal seems to be accepting the concept. Baleen whales can have streamlined or large bodies, depending on the feeding behavior, and two limbs that are modified into flippers. 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. If a designer were building whales and snakes from scratch, why would he include useless legs? organs show a loss of structure, they don't help evolution, since evolution I found an individual with protruded rudimentary hind limbs ... protruded What evolutionists claim is that these bones are vestigial organs that used to be hind limbs and they lost the use of them. 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.
