But no fruitful Techtelmechtel?
The current results of Eriksson and Manica are based on computer models suggesting that the genetic similarities are due to the development of both human forms from a geographically defined population. The early humans, who developed into Neanderthals in Europe and Asia, could have emigrated from a population in northern Africa. Then, on the black continent, the modern human developed, parallel to the Neanderthal in Europe. In northern Africa, genetically speaking, this new human form was still closer to the Neanderthal than to the rest of the continent. From the north, 60, 000 to 70, 000 years ago, modern people set out to settle the world. According to Eriksson and Manica, they shared their common heritage with the Neanderthals.
"We can not prove that there have never been any hybridizations, but all the study results so far do not show that it had to be that way, " says Andrea Manica. However, that could change soon, say Svante Pääbo and David Reich of Harvard University opposite the science magazine? New Scientist ?. New investigations into the traces in the genetic material therefore indicate a cross again 47, 000 to 65, 000 years ago. The corresponding study results should be published soon. It would therefore be premature to already write off the crossing theory. displayAnders Eriksson and Andrea Manica of the University of Cambridge: PNAS, doi: 10.1073 / pnas.1200567109 © science.de?
