Quizplus · Accepted Answer

Homologies are indeed similarities that are inherited from a common ancestor. This can be seen in traits such as the pentadactyl limb, which is found in mammals, birds, reptiles, and amphibians, and is believed to have originated in a common ancestor that lived millions of years ago. Other examples of homologies include the similar bone structure in the forelimbs of humans, bats, whales, and cats, which suggests that these species all evolved from a common ancestor with forelimbs that had a similar bone structure.
