Question

appendix and ceacum are non functional in all the human beings why?

Answer 1

Appendix is a vestigial organ in modern humans and was functional only in our ancestors. Although it acts as a storehouse for good bacteria. But in ancestral forms it served the purpose of digesting leaves and some other functions also.
Caecum digest plant based food material. It harbours bacteria which help in digestion of cellulose. The herbivores entirely dependent on plant material for nutrition have caecum. In case of human we don't rely entirely on plant material for our food, so it is poorly developed or non-functional in humans.
