Question

How are wisdom tooth, appendix, body hair, coccyx useful in other animal?​

Answer 1

Answer:

In the context of human evolution, human vestigiality involves those traits (such as organs or behaviors) 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. Vestigal organs are sometimes called rudimentary organs.[1]

Answer:

Anthropologists believe wisdom teeth were especially helpful for our prehistoric ancestors, who needed serious chewing power to grind through the rough plants, seeds, nuts and foliage which made up the bulk of their diets. As teeth wore down or fell out, wisdom teeth could step in and provide a much-needed replacement.
