Discover common ancestors of modern people and extinct people

An unknown ancient species gave birth to both modern humans and extinct Neanderthals, in a miraculous evolution of 800,000 years ago.

The group of scientists headed by anthropologist Aida Gómez-Robles, from University College London (University of London, UK) analyzed nearly 1,000 tooth samples belonging to at least 122 individuals belonging to 8 groups of ancient people , including the Homo Sapiens ancestors - also known as the wise or modern , are us.

Some teeth have revealed the appearance of an ancient ancestor between us and the Neanderthals warrior - (photo provided by the team).

As many other studies have demonstrated, our Homo Sapiens are just one of many species of the genus of humans in Earth's evolutionary history. However, our relatives became extinct and tens of thousands of years ago, Homo Sapiens dominated the entire human world.

This new study partially deciphered the big question "Where do we come from?" When found the chain is missing 800,000 years ago - a very long time with human life but only a relatively short paragraph in the evolutionary history of his genus. They discovered that we share the same bloodline as the Neaderthals, an extinct human being that can even be said to be more beautiful and muscular than modern humans, skilled warriors of mammoth hunters and last brothers. leave the human world together (about 30,000-50,000 years ago).

The trace on teeth with similarities, evidently evolved from a source that manifested the appearance of a mysterious common ancestor between us and the Neanderthals and not Homo heidelbergensis as previous studies suggest see.

"Homo heidelbergensis cannot take that evolutionary position because it delays the difference between Neanderthals and modern people," Gómez-Robles told Live Science . According to him, this common ancestor was older than we thought and before 800,000, their children had actually evolved into two different species of humans, Neanderthals and Homo Sapiens.

The study also explains some earlier findings that modern humans have nearly 3% of the Neaderthals DNA. Researcher Gómez-Robles stressed: "Nearly 1 million years of evolution is not enough to establish genetic, endocrine and behavioral barriers . to decisively separate these two species".
