We have six body parts that we no longer use. Why are they needed?
We have six body parts that we no longer use. Why are they needed? Wiggling ears, and a third eyelid — millions of years ago our ancestors found a use for them. Despite the fact that some human bodies have ceased to function, people still are born and live with the “evolutionary remnants”. Some distinctive features of organisms persist for many generations even after the appropriate authority has ceased to perform the allotted function. These evolutionary remnants, or vestigial features, there are people. “Your body is, in fact, the natural history Museum!” — wrote in “Twitter” evolutionary anthropologist Dorsa Amir. So why are these properties or organs are not lost, despite the fact that they, apparently, have lost their function? Because evolution is a gradual process.
