Question

Sequencing of the the human genome has revealed a startling fact that most of us contain small but identifiable amounts of DNA that came from Neanderthals. It is now quite clear that early human populations interacted with - and interbred with - Neanderthals. As a result, many modern human populations around the globe carry a small percentage (0 to 5%) Neanderthal DNA in their genomes. This fact became clear when Neanderthal genomes were sequenced and the person primarily responsible for that was Dr. Svante Pääbo, a Swedish geneticist now directing the Laboratory of Human Evolution in @the Max Plank Institute in Germany.  "A Neanderthal Perspective on Human Origins with Dr. Svante Pääbo - 2018."

Answer 1

The presence of the Neanderthals DNA in the modern humans indicates that the Neanderthals and modern humans must have interbred at some point. It means that the Neanderthals and the modern humns co-existed, possibly in Eurasia. The interbreeding evidence between the Neanderthals and the modern humans support the hypothesis that the modern humans evolved in Africa and then expanded out of there. The Neanderthals lived mostly in Eurasia, and the modern humans must have expanded out of Africa to Eurasia, where they interbreeded. It is a result of this interbreeding that the humans today have the Neanderthals genome (0-5%)..
