Many species have vestigial structures, especially in the animal kingdom. Two good examples are the vestigial legs in whales and some snakes. This is clear evidence that whales and snakes are descended from creatures that had functional legs. This is strong evidence of evolution, since there is no other plausible explanation, religious or scientific, for vestigial structures.
