Question

human tail bone is said to be vestigial organ .......give reasons .......please answer....its really urgent....

Answer 1

Ans. Vestigial organs are those which do not have any use in present form. The coccyx is a remnant of the tail bone of our ancestors who used to have a tail. That means it was part of the tail, which hopefully, you don't have (otherwise you'd be a case of atavism, but let's leave that for another day). And hence the coccyx is a vestigial organ.

human tail has no use now thats why it is said to be vestigial organ
