The human body has been a work in progress for about the last six million years, so it’s understandable if over that time we’ve outgrown some of our components. Our tonsils, once intended to be the all-natural wall nasty pathogens need to penetrate in order to call our bodies home, are now usually infection culprits themselves. When was the last time you heard tonsils being name-dropped if it wasn’t in reference to having them removed? Much like the appendix, which humans did at one point rely on to help digest a diet much heavier on the greenery, tonsils are now something that have become a cottage industry for surgeons. When in doubt, grab a scalpel and start slicing.
Evolution has given the human body some odd parting gifts, like the appendix. People just don't eat as much tree bark as they used to.
