Another human being became extinct because of the 'marriage of death' with our ancestors

A team of scientists from Stanford University (USA) has analyzed many archaeological evidence related to Neanderthals and discovered that the interference with humans, with many aberrant love affair, may be humanity makes this ancient man wonderfully on Earth.

As many studies have shown, the humans on earth have previously had many different species. For many reasons, all other species are extinct, the only surviving species called Homo sapiens - the wise or the modern, is us.

The Neanderthals are the other human species dating back to us. According to the study, more than 130,000 years ago, when Homo sapiens left Africa, they met Eurasian Neanderthals in an area called the Levant in the Eastern Mediterranean.

Here, two humans live in peace and many heterosexual marriages have occurred. The encounter of two species also means that each species will have to deal with countless strange pathogens that the remaining species.

Usually when a disease persists long enough in the community, the next generation will possess the genes that help them better immunize it. Therefore, tropical diseases that are familiar and do not cause much harm to Homo sapiens can kill Neanderthals, and vice versa.

Unfortunately, the tropical disease brought back by Homo sapiens was more complex and more severe than the temperate diseases of the Neanderthals, so they turned into the damaged community.

Heterosexual marriages are the last death: a hybrid generation with genes that help fight the disease of the two born species. These strong crossbreds continue to spread their bloodline in both communities, helping them to gradually fight off the diseases of both.

Luck again belongs to us Homo sapiens. They were soon immune to Neanderthals diseases before the other could. Homo sapiens gradually invaded the living areas, increasing the population, while the Neanderthals community gradually shrunk to become completely extinct in the disease.

All of the aforementioned problems have been revealed through the remains, objects and other evidence of the time the two species lived together in the Levant - Cyprus, Israel, Jordan, Syria, Egypt and Iraq today. The authors believe that other human species also went missing after a period of living with Homo sapiens for that reason."That may even be the main reason why modern humans are now the only group of people left on the planet," said lead researcher Gilli Greenbaum.

The work has just been published in the scientific journal Nature Communications.
