Ton grand-papa néandertalien

De récentes études en génétique indiquent que nos ancêtre homo sapiens se sont reproduits avec des Néandertaliens et ce, jusqu'à tout récemment. Certains de leurs gènes sont d'ailleurs encore avec nous aujourd'hui!

Extrait de la fascinante nouvelle:


The last sex between Neanderthals and modern humans likely occurred as recently as 47,000 years ago, the researchers added.

(...) In 2010, scientists completed the first sequence of the Neanderthal genome using DNA extracted from fossils, and an examination of the genetic material suggested that modern humans' ancestors occasionally successfully interbred with Neanderthals. Recent estimates reveal that Neanderthal DNA makes up 1 percent to 4 percent of modern Eurasian genomes, perhaps endowing some people with the robust immune systems they enjoy today.

The Neanderthal genome revealed that people outside Africa share more genetic variants with Neanderthals than Africans do. One possible explanation is that modern humans mixed with Neanderthals after the modern lineage began appearing outside Africa at least 100,000 years ago.
