Study: The Neandertaler is in our skin and psyche

The genes of the Neanderthals are in our hair and our skin. This results in a recent study.

Sleeping and smoking like a Neandertaler
Neanderthal genes still influence the color of our skin and hair, as well as different aspects such as the mood, the tendency to smoking and the awake sleep rhythm.

Circa 2%
of our DNA comes from Neandertaler and affects our skin
and hairfabe.

Adaptation to Eurasia
The reason for these tendencies could be the adjustment of the Neandertals to the solar radiation of Eurasia. The Neanderthals, which is equipped with strong bones in comparison to Homo Sapiens, is regarded as a form of man, set in a cold climate.

In the modern human being the genes were transferred
Janet Kelso from the German Max Planck Institute for Evolutionary Research says: "We speculate that the identification of neandertal genes in our study indicates that exposure to the sun formed this part of the DNA and that these"

Two Percent Neanderthals
An estimated 2% of our DNA in non-Africans comes from Neanderthals, who gave birth to children with our ancestors.

Study on 112,000 people
The scientists studied the genetic information of 112,000 people in the British biobank pilot study and found the evidence that the Neanderthal DNA affected the appearance of human skin and hair.

link 100,000 years ago
Kelso says modern humans from Africa would have hit Neanderthals about 100,000 years ago in Eurasia.

Neandertals were there
The solar irradiation in the region, where both kinds of humans met, in the evolution probably supposedly shaped how the Neandertals developed specific physical adaptations to the UV rays of the sun, she explains.

Research is at the beginning
Kelso's team is planning systematically to research the influence of Neanderthals on modern humans.

Significantly earlier mixing
The Max Planck Institute had already demonstrated in 2016 that Neandertaler and modern humans were genetically mixed 100,000 years ago. Sergi Castellano, a scientist working there, said: "Since the deciphering of the Neandertaler genome, we know that the genetic material of today's non-Africans contains Neandertaler DNA and Neandertaler and modern humans have intermixed.(...) Now we have found human genome in the Neanderthal genome, possibly as a result of much earlier mixing. "

How did the researchers go?
Martin Kuhlwilm from the Institute explains the method: "Because non-Africans living today have Neanderthal traces in the genome, their data were not suitable for our study. Instead, we used the genomes of people living in Africa today to identify those mutations that most of them have in common. Some of these mutations occur in the same regions in Neandertal genome from the Altai mountains, suggesting a mixture. "

Neanderthal Genes in the Immune System
As early as 2016, researchers explained: Neandertaler genes enhance our immune system.

Mixing 40,000 years ago
Already in 2015 scientists examined a 37,000 to 42,000-year-old mandible of a modern man from Romania and found in it up to nine percent Neandertaler DNA.They concluded that he had a Neanderthal ancestor four to six generations before.

No primitive man
The Neandertaler was regarded as a primitive preform of man for a long time. Today, we know that he was physically different from modern man, but not "stupid".He developed culture as well as medicine and religion.
