The evidence for evolution in whales can be seen in their skeletal structure, particularly in the remnants of hind leg bones found within the body. These vestigial bones indicate a shared evolutionary history with land-dwelling mammals and suggest that whales evolved from terrestrial ancestors.

Humans: the appendix, wisdom teeth, and ear muscles are examples of vestigial structures. Whales: hip bones and hind limb remnants are vestigial structures in whales. Pythons: pelvic spurs, remnants of hind limbs, are vestigial structures in pythons.
