Science has now proven that although our ancestors, i.e. the first members of the human species called Homo sapiens, and another human species, Homo neanderthaliensis, lived on Earth at the same time until the former replaced and virtually destroyed the former (along with many other species). human species together). Meanwhile, Neanderthals and our ancestors were not so different that they were unable to produce reproductive offspring. The result is that many Neanderthal traits are still present in us today, to which we owe our lives.
An important trait of our Neanderthal ancestors
The two human species lived side by side for thousands of years, we can say so peacefully, but perhaps not, at least that is what archaeological finds show, which prove, for example, that in some cases Homo sapiens hunted To Neanderthals. Since they were always outnumbered by their relatives, they won.
But there were also romantic moments between the two human species, which led to the mixing of genes and the transfer or change of certain traits in the Homo sapiens gene pool. An example of this is Pain Tolerance, an article from iflscience.com according to It could be a savior for our ancestors.

The Indians’ ancestors would have interbred with most Neanderthals
According to data from a new study that examined 7,000 people, individuals living today who carry three Neanderthal gene variations are more sensitive to effects on the skin. The three genetic variants – M932L, V991L, and D1908G – were transferred from Neanderthals into our genetic pool. In 1623, they found that those with these three variants in their genes were more sensitive to mustard oil (an irritant), but not to heat or pressure. If all three variables are present, this sensitivity is greater.
Interestingly, the study was conducted on another 5,971 citizens of Brazil, Chile, Colombia, Mexico and Peru. There, they found that the prevalence of these three variants was higher in people of Native American descent. This was highest in Peru, because the percentage of people of Indian origin (i.e. the percentage of people of Indian origin) is highest there, 66%.
Pierre Vaux is the author of the study To the science of lice In this regard, he said that it appears that the ancestors of Homo sapiens who arrived in America mostly interbred with Neanderthals.
The aim of further research might be whether Neanderthals also had a lower pain tolerance. By the way, the literature describes these Neanderthals as powerful hunters, because they had to survive in the colder Eurasian regions at that time. Meanwhile, feeling pain is not necessarily bad, as it can be life-saving in certain situations (a zombie that does not feel pain will attack anything without further ado). A low pain threshold may have provided our ancestors with an evolutionary advantage.
In addition, we may have inherited it from Neanderthals The shape of our nose, Our sensitivity to Covid-19 And what is called For Viking disease Our tendency.
