Vestigial organs

Question

Vestigial organs

Quizplus · Accepted Answer

Vestigial organs are remnants of structures that were functional in ancestral organisms but have lost their function over time. The human appendix and wisdom teeth are examples of vestigial organs in humans, as they are remnants of structures that were functional in the ancestors of humans but have no known function in modern humans. Similarly, a snake's hipbones are vestigial structures, as snakes evolved from ancestors that had legs, but have lost their legs over time. While vestigial organs may be similar in different organisms, they do not have to have evolved individually in each organism.
