All humans are different in all aspects, from the physical to the most personal, but one of the most varied characteristics among us is the nose, there being so many forms of this part of our face, and this is worldwide, not just in our country, but have you ever wondered where the shapes of our nose come from?

It is something quite curious, to tell the truth, but here we will give you an explanation for this unknown.

Everything comes from a publication made by one of the most prestigious scientific magazines in the world, Nature en Communications Biology.

And it is that scientists from various parts of the world have started discovering something that really leaves us speechless. It is nothing more and nothing less than news that has to do with our ancestors, since the Neanderthals gave us the structure of the nose as an inheritance.

As you read it, the Neanderthals, in case you know us, was a species of Homos that existed almost 200,000 years ago, and its extinction was about 40,000 years ago, shortly after Homo sapiens appeared.

Since you know this, we continue with the news. So, to come up with this result that has caused a stir, we tell you that more than 6,000 Latin Americans were studied for this research, the genome of each person’s facial skin was taken into account.

One of the most important points is that, according to National GeographicOne of the functions of the nose is to adjust the air that we are breathing, keeping both the temperature and the humidity in favorable conditions for our nose.

Therefore, it is believed that the different types of noses of the Neanderthals were due to the place where they were, since their noses adapted to the environment.

33 regions of genomes were obtained according to face shape, and 26 were subsequently compared with other ethnicities (people from Africa, Asia, and Europe).

The result was that Americans and East Asians carried the gene that Neanderthals inherited, resulting in a larger nose.

Another important finding that mentions the Global University of London of these researchers is that the DNA of the archaic (not Homo sapiens) was seen in our face, affecting it with different features, and that the shape of our lips was also influenced by the Denisova man. The latter is a species that existed at least 100,000 years ago, and although very little is known about its appearance and its way of being, it is known that it had a large jaw and a slightly wider head than normal.

All this turns out to be quite interesting, because if you have ever looked in the mirror, trying to know where the shape of your nose, lips, among others, comes from, then we tell you that the answer lies in our ancestors.

Share science, share knowledge.
