New genetic analysis showed that some of the human X chromosome derived from the Neanderthals, according to "Fox News". The ancestors of Neanderthals have left Africa before 400,000 to 800,000 years, and most of them settled in the area of today's France, Spain, Germany and Russia. They are about 30,000 years ago died out or have joined the population of modern humans. The ancestors of modern humans left Africa prior to about 50,000 to 80,000 years.
They found, however, that some X chromosomes come from Neanderthals and considered that these two types of mutually intersected.
Scientists believe that the crossing, probably happened in the Middle East.
Neanderthals, since they had a gene for speech, they were skilled at making weapons and tools as they had a sense for music, you probably were not averse to modern man. Experts say that these two species almost certainly intersected, but that should still make additional research to reveal more details.
