Modern Europeans’ DNA is Mixture of three populations: Study
In order to know more about the ancestral roots of modern Europeans, scientists analyzed the strands of DNA taken from ancient corpses. The findings showed that the first Homo sapiens arrived in Europe almost 45,000 years ago, and were later replaced by early farmers who brought agriculture to the continent more than 7,000 years ago from Anatolia and the Levant region in the near east.
Researchers believed that these two groups contributed significantly to make up the most of the European gene pool. Further, genetic study by researchers disclosed that some part of it was still missing, which indicated that these two groups were not wholly responsible to make up the entire European gene pool and some European DNA came from somewhere else.
To solve the puzzle, researchers in Germany and the US sequenced the complete genetic code of nine ancient humans. This included a 7,000-year-old farmer from Germany and 7,000 to 8,000-year-old hunter-gatherers from Luxembourg and Sweden. Scientists then compared these genomes with the DNA taken from approximately 2,000 modern-day people from various parts of the world and with other ancient genomes.
The findings of the comparison showed that the DNA of almost all modern Europeans was a mixture of western European hunter-gatherer and early European farmer DNA, including a mix of north Eurasian.
Johannes Krause, at the University of Tübingen's Institute for Archaeological Sciences, said, “It became very clear that all Europeans have hunter-gatherer as well as early farmer DNA to varying degrees, but it was also very clear that something was missing here in the makeup of modern Europeans”.
Researchers stated that it is very clear from the study that modern Europeans DNA is a mix of three populations. They said that Sardinians are more than 80% early European farmer, with less than 1% of their genetic makeup coming from the ancient north Eurasians.
In addition, the modern English inherited almost 50% of their genes from early European farmers, 36% from western Europeans hunter-gatherers, and 14% from the ancient north Eurasians.
