A fascinating new study whose online component has an interactive DNA map has provided a dramatic visual overview of the racial history of selected groups around the world—and has confirmed the essential thesis of March of the Titans.
The new study, titled “A Genetic Atlas of Human Admixture History,” published in Science 14 February 2014: Vol. 343 no. 6172 pp. 747-751 (DOI: 10.1126/science.1243518) says the following in its abstract summary:
“Modern genetic data combined with appropriate statistical methods have the potential to contribute substantially to our understanding of human history.
“We have developed an approach that exploits the genomic structure of admixed populations to date and characterize historical mixture events at fine scales.
“We used this to produce an atlas of worldwide human admixture history, constructed by using genetic data alone and encompassing over 100 events occurring over the past 4000 years.
“We identified events whose dates and participants suggest they describe genetic impacts of the Mongol empire, Arab slave trade, Bantu expansion, first millennium CE migrations in Eastern Europe, and European colonialism, as well as unrecorded events, revealing admixture to be an almost universal force shaping human populations.”
This remarkable study’s online element can be found here, or by clicking on the graphic below.
By clicking on a population group on the map, an automatic display comes up showing the broad genetic compositions of each sample group.
It is important to note that the results are, of course, only based on the returns provided by each sample group, and should not automatically be presumed to be representative of every single individual in that particular group.
Nonetheless, the map essentially proves once again the accuracy of the historical account of racial demographic population shifts, as outlined in March of the Titans.
