Humans were originally Neanderthals and before that, we were all hunter-gatherers. But even before we started becoming bipedal creatures we were a part of the ape species, where hair covered our bodies and we crawled on all fours. But biology has altered us and we split from our cousins; the primates. We began to hunt, use tools and walk on two feet whereas monkeys and primates more or less just stayed the same.
But there are some traits that we have inherited from our very first ancestors that may no longer be useful to us nowadays.
In the future, some of these traits may not be present in the human body.
1. Body hair. Body hair played a significant role not only in producing warmth (since Neanderthals didn’t wear clothes back then) but also for males to attract a potential mate.
2. Paranasal sinuses were designed in order to make our heads lighter. This might have something to do with humans switching from walking on four feet to walking on two.
But nowadays scientists are not sure why we still have them.
3. Most humans can’t wiggle their ears. Despite the fact that we have the auricular ear muscles that cats and dogs have to wiggle their ears, most of us are unable to use them and they really serve no purpose in the modern age.
4. Wisdom teeth used to play a vital role in the consumption of plants, but in 5 percent of the population, wisdom teeth serve absolutely no purpose aside from a mounting dentist’s bill and some horrific pain.
5. The neck or the cervical rib. This rib is thought to be left over from the age of reptiles. Some humans still have this rib but it is notorious for causing nerve and artery problems.
6. Palmaris muscle. The palmaris muscle was extremely important for climbing back in the day but now it is missing in almost 11 percent of the population.
7. Nipples. The nipple has long been known as the spot on a female for lactation but the purpose of nipples on a male has yet to be discovered.
8. The goosebumps muscle or arrector pili muscle. This muscle is used by animals for intimidation or for warmth but since humans have little to no fur, the act of getting goosebumps is really pointless.
9. Appendix. The appendix is a muscular tube that is attached to our large intestine. It used to be an integral part of digestion for plants but nowadays, with most people eating fewer vegetables, it has become more prone to infections.
10. Thirteenth rib. The thirteenth rib originates from chimps and gorillas who all have that extra set of ribs. However, only about 8 percent of humans nowadays have that thirteenth rib.
11. Studies have shown that humans mostly balance on the midline of their feet and not so much with their toes. What is just as interesting is that the human center of balance is still shifting to this day. Meaning that toes could no longer be present in future humans.
12. Coccyx. Also known as the tailbone, the coccyx is exactly what its name denotes. Scientists believe that this used to be the spot where our tails were attached but no one is quite sure why we still have one now.
13. Third eyelid. The third fold in our eye is our third eyelid but biologists have shown that the modern human has no need for it.
14. Darwin’s point refers to that small part of the folded skin on the corner of your ear. The purpose for this folded skin was so that the larger shape could help capture more distant sounds.
15. Subclavius. The subclavius is a muscle that the modern human has but it used to be a vital role in helping the first humans walk on all fours.
