Answer 1

Vestigial organ appendix present in human body is proof of evolution.

Explanation:

The appendix, which is useless to humans, is a useful and fully functional organ in ruminants. Similarly, muscles of the ear pinna, which are useless to humans, are useful in monkeys for the movement of the ear pinna. Various vestigial organs like the tailbone (coccyx), wisdom teeth, and body hairs are present in the body of a human being.
