Within a few million years, those leg bones were pretty much gone, too. But a popular image of a surfacing beluga has for years created the curious illusion of a whale with legs and knees. Also, there's a theory about whales being evolved from wolf-like creatures. The skeleton inside a whale's flipper looks like a version of a human hand; containing a shoulder, upper arm bone, lower arm bones, wrist bones and phalanges, or finger-type bones. Whales have real bones. iStockphoto. That's because evolutionary accounts of function are historical. By Tim Marcin On 6/7/18 at 1:47 PM EDT. But lacking legs, whales have no use for hip bones, rendering these structures without function in the present. The closest is some small bones that serve as anchorage points for the reproductive organs and on the basis of evolutionary theory these are interpreted as remains of the pelvis and hind limbs. Beluga whales aren't hiding legs under their thick, rubbery skin. Scientists believe these are vestigial remnants of what were once hind legs. 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. The whales with big hip bones also tended to have big testicles and big penises. This is a problem for evolutionary accounts of function. Snakes and whales do not have hind limbs. What evolutionists claim is that these bones are vestigial organs that used to be hind limbs and they lost the use of them. [edit] Whales do not have leg bones. 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’. Scientists have proven that these animals walked the earth as land mammals about 175 million years ago. When their weight became too heavy for them to run and catch animals for food they gradually started drifting towards the ocean in search of fish for food and as time went on permanently became sea mammals. Why do whales have leg bones? If they didn't they would've been ginormous jellyfish. Anyway, the song was right. Beluga Whale 'Knees' Are Going Viral but, Of Course, Whales Don't Have Legs. But unlike fish, they have large ribs around their lungs, and the bones inside their flippers have five fingers exactly as do human hands. 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? The image, which excites the web from time to time, has recently turned up again. Hats off to your work in showing the flaws of evolution! Maybe the person that was thinking cartilage was thinking about sharks.) Whales also contain several small bones floating down toward their tails. (Shark skeletons are mostly cartilage. Few animal traits are trotted out as illustrations of evolution as often as the whale’s supposed vestigial hip bones. Real bones made with real calcium. The fact that whales have pelvic and leg bones indicates that: A. they probably evolved from fish B. ancestral whales had legs C. whales should have functional legs D. having a pelvis is advantageous E. whales did not evolve by natural selection Whale bones are on display in many museums and can be found on many beaches where a dead whale washed ashore or maybe where a beached whale died. They do have certain bones in the hinder part of their bodies, but they do not use them for walking or locomotion. On these accounts, the function of the whale's hip bones is something like connecting up with the whale's leg bones.
