Are cat whiskers a vestigial structure?
A vestigial structure is a structure that an organism still has but no longer serves any real definite purpose. In this case, the whiskers on a cat serve a vital purpose, so they are not vestigial structures.
What is the difference between homologous analogous and vestigial structures?
pickles :3
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.
What causes the difference between the ancestor and modern koalas?
a. the presence of homologous structures b. the presence of vestigial organs
Why are vestigial structures evidence of evolution?
Because of the morphological homologies they display with similar structures in other extant and extinct lifeforms, following, like virtually every other morphological or anatomical feature of life, the nested hierarchies of biology.
What is the term for structure that has no use in an organism?
Vestigial StructureA vestigial structure is a structure that appears to no longer have a use in the body.
Would vestigial structures make any sense if organisms did not evolve?
No, because the use now would be the use then which is not really vestigial.
How do vestigial structures work?
They don't, vestigial structures are biological structures with no known function that evolved from structures in distant ancestors that used to have a function that is no longer needed.

How do you define vestigial structure?
Vestigial structure is used in application to structures that are determined genetically but do not have the ancestral function.
What Organs that are so reduced in size that they are just vestiges of homologous organs in other species are called?
Vestigial Organs
Vestigial structures in humans?
