Describe evidence that supports the hypothesis that whales evolved from land-dwelling mammals.

There is a vestigial pelvic bone in whales which makes some people believe that their ancestors walked. Bones in the flippers have the same bones as land mammals arms and birds wings do which indicates divergence from the same ancestors.

Whales have evolved from land-dwelling mammals, with evidence supporting this hypothesis found in fossil records, vestigial structures like pelvic bones, homologous anatomy with land mammals, genetic links to hippos, and similarities in embryonic development. This collective evidence illustrates a clear evolutionary transition from land to aquatic life. Together, they reinforce the understanding of whales' ancestry and adaptations.
