What they failed to find was the presence of human DNA samples in the other Western European
MADRID, February 18 2016.- The world was very different then. Several human species is divided continent. Neanderthals inhabited Europe and parts of Asia. The Homo sapiens in Africa dominated. And other species, such as Homo erectus or Homo floresiensis, lived in the East. No less than 150,000 years ago much of that, a sigh in evolutionary or geological terms, but a whole world if we close the focus to the history of the most recent human evolution.
Those Taifa kingdoms were not watertight and different populations migrate in search of better lands pushed by the harsh climate. During the Ice Age, when the Arctic ice down to the latitude of the Iberian peninsula, the various Eurasian species sought refuge in warmer southern areas, detailing the World.
But the Sahara became more arid during these periods but not as much as the Sahara we know today-, which incited the populations which inhabited him to try his luck further north. The meeting was served.
And that is exactly what happened 120,000 years ago, during the onset of the last ice age Europe, known as Würm. At that time Neanderthals and modern humans shared territory in Southeast Asia, and sometimes intimate relationships.
Since the publication of the first draft of the Neanderthal genome in 2010, researchers already knew that the two species interbred and that, in fact, part of the genetic information of the current European and Asian contains just under 3% of Neanderthal DNA.
But it was thought that these sexual encounters were not produced until 47,000 and 65,000 years. Now, thanks to a newly published research in the journal Nature, we know that there were also crosses between two species at the glacial world 100,000 years ago, about 40,000 years earlier than previously thought. In addition, the study documents for the first time the presence of DNA of Homo sapiens Neanderthals.
