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.
