The Degree and European Antiquity of the African Ancestry of the Present Ones
Sunday, May 13th, 2012David Reich, Priya Moorjani and Alkes Price – people from Harvard University – make use of the modern genetics as a tool for tracking down one’s origin instead of just merely using it for predicting the tendency of each person to certain health problems. This new study contributes to revealing data about the migration of European, African population, and Middle East in ancient times.
The instrument of the three researchers identified a proportion of Sub-Saharan African ancestry existing in a particular population of Eurasia, the geographic area that includes modern Europe and the Middle East. Unlike the previous studies of this mixed ancestry, they quantified the percentage of African ancestry present among the European and Middle Easterners.
The researchers did not find any African genetic tracks in the Northern European population. However, they detected the presence of Sub-Saharan African ancestry among the Southern Europeans, Middle Easterners and the Jewish population.
The researchers said that Southern Europeans can attribute 1 to 3 percent of their genetic track to African ancestry and that they can date their Sub-Saharan African ancestry back to 55 generations or about 1,600 years ago. The population in the Middle East acquired 4 to 15 percent of African ancestry with the mixing of populations dating 32 generations ago. While, in a vast range of Jewish population, it was identified that its Sub-Saharan African ancestry goes back to 72 generations and that they constitute 3 to 5 percent African genetic composition.
These findings address the enduring debate over African multi-cultural influences in Europe. The dates of population mixtures agree with the documented historical events. For example, the blending of Southern European and African populations corresponds with the events that happened during the Roman Empire and Arab migrations that succeeded. Even the mixture dates among the Jewish and African populations are correlated with the Biblical events. However, Reich emphasized that they are not claiming that the African ancestry is connected with migrations associated with the events in the bible. Nonetheless, he defines it as interesting to speculate.
Thanks to the modern genetics for providing us information regarding the DNA linkage of Europeans, Middle Easterners to the Sub-Saharan Africans. Definitely, population boundaries that most people think as impermeable are, in fact, not that way.
