What do you think is the useless body organs? That was the question. I think it’s appendix (my class too) is the useless body organs. Appendix is not useful anymore since we stopped eating uncooked or low-quality food like grass. In the same way, wisdom teeth are no longer useful. The appendix as the wisdom teeth lost most of its ancestral function. Since we eat soft food they lost their utility. Thirdly, tonsil is one of them that we ask why we have it. It’s not completely useless but it creates a lot of problem to some person when it gets inflamed and infected.
