Which statements describe homologous structures? Select three options.

Homologous structures share an underlying anatomical pattern inherited from a common ancestor, even if they serve different functions. The forelimbs of whales, humans, and dogs have related bone structures, so B is correct, and D describes the same pattern. Homology is evidence of common ancestry, making E correct. A bird’s wing and an insect’s wing have similar functions but different underlying structures, so they are not homologous.
