Please keep in mind that these are just theories and it’s a possible way of evolution!
According to Darwin’s theory of evolution humans evolved from apes. Before evolving our bodies were all covered by hair and we were crawling on our fours. While the apes stayed almost the same, we changed and started walking on two feet. We have inherited some traits that are useless nowadays.
It’s considered that our bodies are constantly evolving. Here is a small list on how we are going change in the next a couple hundred years.
1. Body hair
In the past, the whole body was covered with hair, which, except for warming, used to attract a partner.
2. Paranasal sinuses
They are designed to make the head lighter and some scientists believe that this have something to do with started walking on two feet. There are different opinions if we need the paranasal sinuses now or not.
3. Auricular ear muscles
You have seen how the cats and the dogs can wiggle their ears. Well, this is thanks to their ear muscles. We also have these muscles, but since we don’t need them (and nobody can really moves his/her ears like that) they are useless.
4. Wisdom teeth
In the past the wisdom teeth were useful while eating plants, but nowadays in most people they are causing just pain. So we just remove them (which is very expensive by the way).
5. Cervical rib (the neck)
It’s considered that it’s left over from the reptile ages. Nowadays there are people who still inherit this rib, but it only cause problems (artery or nerve problems).
6. Palmaris muscle
This muscle used to be essential for climbing, but now it is missing in over 10% of the population.
While female nipples have always been associated with lactation, men do have nipples, because in the first few weeks male and female embryos have the same blueprints. Anyway, the man’s nipples are completely useless.
8. The goosebumps muscle
After we almost have no fur, goosebumps may be pointless, because animals use it for when endangered or cold.
The appendix used to be an important part of the digestive system when humans used to eat a lot of plants. Nowadays, people eat fewer vegetables and the muscular tube that connects our large intestine is vulnerable to infections.
10. Thirteenth rib
The gorillas and chimps have an extra set of ribs, including the 13th rib, but only 8 percent of the population do having one.
According to a recent research humans balance on the midline of their feet and we no longer need our toes. So, basically we are shifting out balance every single day and in a couple hundred years most of them will be completely useless.
It is already proven that people without toes can live healthy and normal life. They just use the rest of their foot and muscles as a compensation.
It’s quite possible, because the horse for example used to have more than just 2 toes.
