Whales have vestigial legs This suggests they?
That they evolved from land animals.
How are scientists able to explain vestigial structures found in whales and some snakes?
These vestigial structure, hip bones and leg bones, attest to the land dwelling ancestor of whales and the leg bearing ancestor of snakes. The inference is rather simple in whales. How else could a water swimming animal posses vestigial legs. For light amusement read some of the creationist non explanations for these vestigial markers. talkorigins.org
Does sperm whales have limbs?
They have the tail and their flippers. Some whales have vestigial(undeveloped) leg bones embedded in their tails.
What is the function of a whales forelimb?
Although it is a vestigial remnant from when whales were land mammals, now it is used to provide some help in steering. Whales have also been observed to 'slap' the water with them.
What is a vestigial structure on modern whales?
Some still have embedded pelvises under a good bit of blubber.
What are the release dates for Vegas Whales Tales - 2005 TV?
Vegas Whales Tales - 2005 TV was released on: USA: 13 January 2005
The pelvic bones of modern whales no longer function like the pelvis of a land animal and are an example of?
vestigial structures.
Whales snakes and dolphins all have vestigial bones that indicate they once had hind limbs Living whales snakes and dolphins do not have hind limbs This is an ex?
There is no answer for this question because it does not make any sense.
Modern whales have a vestigial perlvis and femur what does this evidence suggest about ancestors of modern whales?
Evidence of a vestigial pelvis and femur suggests about the ancestors of modern whales walked on land and thus, also breathed air. Many other marine life is believed to have been land based before massive climate change and perhaps floods.
Why are vestigial structures considered critical evidence of evolution?
Vestigial structures are considered evidence, but no more critical than any other line of evidence in Biology and palaeontology. They're considered evidence, not because of their function, but because of the way their morphologies follow the nested hierarchies of biology: the vestigial legs of whales, for instance, have exactly the kind of shape we would have expected them to have if whales had descended from land mammals. The same goes for human tailbones and embryonic branchial ridges, the wings of emus, and so on.
Do dolphins have hip bones?
Yes! They are vestigial (not serving a purpose biologically), and are remnant from a time when early early ancestors of whales were land based animals.
Why is a whales hind legs a vestigial organ?
Yes they do. They are detached from the vertebral column and float free though.
