The human body is an amazing organism, to say the least.
To watch an athlete dunk a basketball or a ballerina turn a pirouette is to witness an extraordinary machine at work. But the human body is also a biological junkyard of useless ideas it has yet to ditch as we evolve.
There are many organs, tissues, and cells that make up the human body that, though they once had an evolutionary purpose for our survival, are now obsolete. Think about your tonsils or wisdom when they get inflamed to the point of needing surgical removal. These and all other “useless” body parts are known as vestigial organs and every species from humans to birds to felines to fish have them.
The video below goes over just a few of the vestigial organs we can locate on our bodies if we know where to look.
