They are examples of vestigial structures: structures that appear to be useless but once most probably had a function
The hind leg bones shown in whales are vestigial structures, remnants of ancestors that once had fully developed hind limbs. These bones provide evidence of the evolutionary transition from land-dwelling mammals to aquatic life. Despite their reduced size and function, they reflect the whale's evolutionary history and adaptation to a marine environment.
Bones of whale ancestors showed that whales had hip bones along with legs and hind feet.

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.
A kangaroo's powerful hind legs can easily break bones.
Tarsal bones are found in the hind legs of an animal. They form the ankle region and connect the lower leg bones to the bones of the foot. In quadrupedal animals, the tarsals play a crucial role in locomotion and support.
A horse's hind end, or hindquarters, contains a pelvic bone, sacrum, and tailbone. The exact number of bones can vary depending on individual variation, but typically a horse's hind end contains around 20 bones.
