7 parts of the human body have become useless over time that you may not know you have

7 parts of the human body have become useless over time that you may not know you have

I know we should treat our bodies like a temple, but some parts of our temples are no longer needed.

Humans first appeared about 2.8 million years ago, and it’s safe to say they did terribly different from how they are now.

From using rocks to start fires to hunting for food, I’m sure we can all agree that despite the shortcomings of modern society, we have it a lot better than our ancestors.

But as society has developed, so have our needs; and apparently there are some parts of our bodies that are now quite redundant with this in mind…

Ear muscles

We have muscles inside and outside our ears, but it’s unlikely you actually use them.

Our ancestors would have been able to move their ears because this helped localize sound, but as the sides of human heads have grown over the centuries, we no longer need them to move.

So if you can wiggle your ears, it’s really nothing more than an entertaining party trick.

Chins

The jury is still out on this one, but some have argued that we don’t really need our chins (but admittedly, we’d look pretty weird without them).

Dan Lieberman, Ph.D., professor of human evolutionary biology at Harvard University, told Women’s Health that it could be possible that we only have chins because we find them beautiful and because they are the result of sexual selection.

Some experts have suggested that the chin is there to help us control our jaws while chewing, as well as other certain so-called mechanical stresses.

Body hair

Once needed for warmth, many people (particularly women) now choose to have no hair on their bodies at all, aside from their heads.

Tina Lasisi, a biological anthropologist at the University of Southern California, previously explained to BBC News: “Technically we have hair all over our bodies, they’re just miniaturized hair follicles.

“But it has been so miniaturized that it no longer functionally isolates us.”

Pink toes

Feet may be one of the most important parts of the body, but the same cannot be said for our pinky toes.

Pinky toes used to be useful for our ancestors when they wanted to climb things, but now they’re just there to rub the inside of your Converse.

Wisdom tooth

There’s a reason why so many of us end up having our wisdom teeth removed, and that’s because we don’t need them.

Paul Sereno, professor of paleontology at the University of Chicago, says, ‘Evolutionarily, humans needed more teeth to support a diet of coarse foods.

“But as our jaws have become smaller and our diets more refined, these teeth have become redundant.”

Tailbone

As the name implies, the coccyx (also called coccyx) is believed to be the remnant of a rudimentary tail.

But according to CNN, humans stopped having such “tails” about 25 million years ago.

“The loss has long been associated with our transition to bipedalism, but little was known about the genetic factors that caused primate taillessness,” the news outlet wrote.

Appendix

Another part of the body that is commonly removed is the appendix, proving that we can live just fine without it.

“Traditionally, medicine assumed that the appendix served no purpose,” says Professor Sereno.

Although we can survive without an appendix, the appendix can have some benefits, such as helping our immune system.

Some scientists and doctors have suggested that the appendix may be a place where our bodies can store certain healthy types of gut bacteria.
