Millions of years ago, humans, like monkeys, had a dense coat of hair. In men, dense hair may appear on the chest. We see that men, especially in countries with a Mediterranean coast, have a lot of chest hair. We can easily see this ratio by looking at the chest hair ratio in our country.

So why are men still? chest hair and especially these hairy people are in the Mediterranean and its environs? Today we are going to explain to you why some people kept their chest hair during the evolution process.

First, let’s see what they are: what is chest hair, also called chest hair in the people?

One of the types of body hair, chest hair or popularly known as chest hair, is located between the neck and the abdomen. These hairs that start growing after puberty It develops with androgenic hair types. These hairs, which usually occur in men, can also grow in women in some cases. These hairs, which develop depending on the level of androgen, can also be seen as sexual characteristics.

So why do men get chest hair?

Human evolution has been going on for a very long time. Many years ago, like our other primate cousins, so did we There were dense fur-quality hairs. Standing on two legs, perhaps humanity’s greatest evolutionary leap, changed the structure of hair growth and many other things. Standing on two legs, man over time realized that hunting did not just meet his food needs. The need for a fur to cover the bodies of people who used the skins of the animals they hunted to protect themselves from the cold began to disappear. Over time, more hairless people began to emerge through natural selection.

The main reason why people still have facial and chest hair today sexual selection considered to be. The moment people lost body hair, women liked men with chest hair more, and that’s how men evolved. Men, on the other hand, preferred women who had no hair on their bodies.

Moving on to the main topic: why do men in the Mediterranean and the region have more chest hair?

First the card you see above in native human populations shows the average body hair of men. As you can see on the map, we see that people in and around the Mediterranean have more hair. Native Americans have less hair.

Sexual selection, arguably the most important building block of evolution, also played an important role in chest hair. secure sexual selection proceeded differently in different ethnic groups. For example, Native American women found hairless men more attractive than men with chest hair. As a result, people who evolved in this region became less hairy.

The reverse of this situation has occurred in the Mediterranean and its region. among men of Mediterranean descent men with more chest hair could pass on their genetics to future generations. Men without chest hair could not pass on their genetics during natural selection. The same isn’t just true for chest hair. The fact that men in and around the Mediterranean have more hair and beards is due to similar sexual selection. We can also add that men are generally beardless in regions such as China and Korea.

Today we explained to you why people in and around the Mediterranean have more chest hair. If you want more of this kind of content, please write it in the comments section.
