It is known that the species of Homo sapiens, which includes today’s humans, lived between 100,000 and 200,000 years ago. neanderthals It is a known fact that they met and some of them were together. It was even revealed that the Neanderthals’ sexual relations with homo sapiens may have brought the end.

So, what remains of Neanderthals today, with the combination of the two species? A new study has provided yet another answer to this question. Some people have Big noses may be based on Neanderthal DNA revealed.

The size of our noses may be due to a gene passed from Neanderthals to humans:

Scientists have examined the DNA of more than 6,000 people in Latin America. He then compared the facial features of the people with this genetic information. In the equation, determine the facial features of the people 33 genomic regions noted.

Of these 33 sites, 26 also seemed to be paralleled in other peoples in Europe, Africa and Asia. In other words, the regions of the genome that determine the facial features of people around the world. were repeating each other.

Our connection to the Neanderthals was seen in one area in particular:

When scientists focused on the region called “1q32.3,” they found traces of Neanderthals. This part of the genome is a cross between Neanderthals and Homo sapiens. determine the height of the nose (Z-axis) was the region.

So why did Neanderthals have a big nose? The answer to this question was provided by the gene known as ATF3, which is located in the same region. Neanderthals, especially in cold conditions, where the gene evolved through natural selection to ensure their survival It was revealed that it caused the nose to grow big.

The function of the gene that is transferred to Homo sapiens was basically the same in us. Gen aimed to help people adapt and survive the cold conditions of the time.
