The forelimbs of mammals are examples of homologous structures.

Homologous structures are anatomical features that are similar in different species because they were inherited from a common ancestor. For example, the forelimbs of humans, whales, and bats. Is a clear example of ___________________ homology, which indicates a common evolutionary origin. Question 8Answera.vestigialb.molecular c.anatomicald.embryological
