Early modern human interbred with Neanderthals

The DNA analysis pointed out that Neanderthals and modern humans undergone interbreeding in Europe. The scientists analyzed 40,000 year old DNA to reach this conclusion. Early Homo sapiens migrants in the Europe included a Neanderthal member few hundred years ago in the family. The interbreeding took place somewhere in the Middle East with Neanderthals around 55,000 years ago. 

Modern humans letter went northwards in the Europe and there they went through another interbreeding phase.  Analysis of the ancient European genome was published in the reputed ‘the Nature’ journal. The researchers across the globe collaborated for the study. Genetic material was extracted and sequenced as per the patterns from a jawbone. 

The fossil was found in south-west Romania’s Peștera cu Oase cave system in 2002.  The jaw was more close to the Neanderthal than any modern species of human, according to the data. 6 % to 9% genome was derived from the Neanderthal’s DNA, very large amount as compared to 2 to 4 percent in present day Europeans. 

The generations pass DNA to the next one through reproduction but the DNA is not entirely copied. It gets reproduced, altered and segmented. The broken material then may get passed to next member of family line through other ancestors with alterations. The fossil suggests that the sample had Neanderthal ancestor around six generations ago. 

Harvard Medical School’s Prof David Reich informed that these are extraordinary findings. The co-author of the paper explained about the implications of the research in the domain of anthropology.
