Humans continue to evolve and adapt to the world around us, we can expect to see some changes in the evolutionary design of the human body. We’ve already started to see some of these changes happening with human body parts.

Research shows that modern humans retain a lot of vestigial organs and evolution is going easy on the pink-slips. Here are the seven organs that scientists think will disappear from the human body

Body Hair

Did you know that eye brows help keep sweat from our eyes? And male facial hair can play a part in attracting the opposite sex? But besides that, the rest of the hair on the body could be deemed practically useless. Over time, you’ll see people with less and less of it.


Some people don’t have extrinsic ear muscles, but those who do can move their ear independently of their head. It’s useless unless you are hunting and need to hear what’s around you.

In the days of the yore, ear muscles were crucial in moving our ears and hearing predators in the wild more clearly. Bunnies still retain these requirements and hence these muscles continue to thrive in them. Over time, humans are bound to lose their ear-flapping abilities because we have outgrown their functionality.

Male Nipples

Essentially, men only have nipples because they could have been female. Males and females develop in exactly the same way for the first 60 days in the womb. For those with a Y chromosome testosterone will then kick in, which will cause male sex organs to develop instead of female ones.
By this point, though, you’re already going to get nipples. But because having nipples doesn’t actually do any harm, they have never been weeded out by natural selection - and so pretty much everyone still has them.


People are moving toward a more centered style of walking, making it less important to have toes. Our center of gravity is based from the middle of our bodies and research is showing that toes might not be necessary to help us walk or run in the future.

Tail Bone

Humans no longer need tails. We’re perfectly good at balancing without them. However, most mammals will have a tail at some point in their lives, even if they lose it by the time they leave the womb. Between weeks five to eight after conception, human embryos seem to develop what looks like a tail forming in the womb but, by the time they are born, it has been absorbed into the vertebrae.

A Third eyelid

At the very corner of your eye, next to your nose, there’s a little flap of skin that doesn’t really need to be there. This is called the plica semilunaris, or the nictitating membrane. Birds and reptiles have these extra translucent eyelids which they can put across their eyes for protection or moisture while still being able to see.

Wisdom Teeth

These big teeth were used to crush food for digestion, but these days, we’ve got forks and knives for that. Most people don’t ever get their wisdom teeth, are born without them or they never erupt.
