Vermiform appendix

Vedclass · Answer

(D) The $Vermiform$ appendix is a vestigial organ in humans. It is a narrow, worm-shaped tube that is a remnant of the cecum, which was functional in our herbivorous ancestors for the digestion of cellulose. Over time, as human dietary habits shifted toward cooked and easily digestible food, the need for a large cecum for cellulose digestion decreased, leading to the appendix becoming vestigial.
