Named the main reason for the extinction of Neanderthals

A group of archaeologists representing the University of Colorado in boulder, said that she managed to find the cause of the disappearance of the Neanderthals. As it turned out, the ancient hominids were ruined by the cold and hunger that it brought. Earlier, a similar version of the extinction of Neanderthals have been disputed because they were considered more adapted to cold than the “principal” ancestors of modern humans.

As is today, Neanderthals first appeared in Europe about 280 thousand years ago and colonized the greater part of this continent, as well as some areas in Asia. After more than two millennia later in Europe also were the CRO-magnons. For a long time, both species coexisted and even interbred, a reminder than serve a few percent of Neanderthal DNA in the genome of any modern person of European or Asian origin.

However, about 40 thousand years the Neanderthals were gone forever, and there’s no scientific consensus on that, were they replaced by modern humans, or the main reason for their disappearance were any other factors. According to the researchers it is considered one of the main mysteries of the prehistoric times, writes the Daily Mail.

The experts, who published their study in the scientific Journal Journal of Human Evolution, suggested that the cause of the extinction of CRO-magnon, though, was climate change, provoked by the eruption of the volcano. Although the body of the Neanderthals, seems to have been better adapted to the cold than Homo sapiens, they were unable to cope with another problem, which cold brought with it the reduction of the number game. In a result in order to obtain enough nutrients, hominids had more diligently to gnaw the bones and suck even the marrow of the hunted animals. As a result, the ratio of energy required to produce food and energy that the body gets the result, it became increasingly unprofitable.
