Human vestigiality
Human traits which lost their original function through evolution / From Wikipedia, the free encyclopedia
In the context of human evolution, human vestigiality involves those traits occurring in humans that have lost all or most of their original function through evolution. Although structures called vestigial often appear functionless, a vestigial structure may retain lesser functions or develop minor new ones. In some cases, structures once identified as vestigial simply had an unrecognized function. Vestigial organs are sometimes called rudimentary organs.[1] Many human characteristics are also vestigial in other primates and related animals.
