FOXNews.com is reporting on a study conducted by Cornell University that found that White Americans are genetically weaker and less diverse than their Black counterparts.
The study, “Genotype, hapoltype and copy-number variation in worldwide human populations,” was conducted to provide data for uncovering the history of migration, range expansion, and adaption of human beings.
After testing 10,000 genes and analyzing the genetic makeup of 15 Americans of African descent and 20 Americans of European decent, researchers found that the Euro-Americans showed less variation than their African American counterparts.
Carlos Bustamante, senior co-author of the study and an assistant professor of biological statistic and computational biology at Cornell stated, “Since we tend to think of European populations as quite large, we did not expect to see a significant difference in the distribution of neutral and deleterious variation between the two populations.”
The study also found that Europeans had more harmful mutations than Africans did, due to their race being “diluted” twice over 30,000 years ago which caused “bad” mutations to build up in the European population. Bustamante calls this a “genetic echo.” Most Non-Africans descended from a small group of migrants who left the African continent 50,000 to 100,000 years ago.
The study also revealed that Native Americas showed less genetic diversity than Europeans. Its proof that the part of the world they lived in was the last to be settled. They are descendents of the Yakruts of Eastern Siberia who entered North America about 10,000 years ago.
The researchers study proved that life did start in Africa with Africans having the greatest amount of genetic diversity, followed by Middle Easterners, then Europeans, South Asians and finally East Asians.
More studies will be conducted by the Cornell team to explore other population groups.
