Detailed explanation-1: -Anatomical similarities, such as those that characterize tetrapod limbs, are used as evidence for common ancestry. In other words, these similarities suggest that pterodactyls, bats, hawks, whales, and humans all share a common ancestor somewhere in their distant past.
Detailed explanation-2: -A common example of comparative anatomy is the similar bone structures in forelimbs of cats, whales, bats, and humans. All of these appendages consist of the same basic parts; yet, they serve completely different functions.
Detailed explanation-3: -Darwin made extensive use of comparative anatomy in advancing his theory, and it in turn revolutionized the field by explaining the structural differences between species as arising out of their evolutionary descent by natural selection from a common ancestor.
Detailed explanation-4: -Embryology Evolution Examples Examples found in comparative anatomy include the forelimbs of humans and the flippers of a whale, which supports the idea of common descent. Although a human arm and bat wing look different, the process of embryonic development is similar.
