This is the blog for GW students taking Human Evolutionary Genetics. This site is for posting interesting tidbits on: the patterns and processes of human genetic variation;human origins and migration; molecular adaptations to environment, lifestyle and disease; ancient and forensic DNA analyses; and genealogical reconstructions.

The Genetics of Staying in School

The article “The Genetics of Staying in School” from The Atlantic discusses a GWAS study done on 294,000 individuals from different areas of the world. The study found 74 gene variants that are associated with educational attainment. In other words, the people who have the variants, on average compete more formal schooling than individuals who do not have the variants. The Manhattan plot showed that there were big statistical differences on chromosomes 2, 3, 6, 9, 13, and 15, as well as some smaller differences on a few others. These kinds of studies can create a lot of public backlash, which is exactly what happened. Thus, the researchers also published a “Frequently Asked Questions” article discussing what the GWAS study really meant. The researchers explained that the 74 gene variants only accounted for 3 percent of the differences in education levels across the whole population. Thus, there are many other factors that affect educational attainment, and that nurture and nature go hand in hand when discussing educational success. However, this study will be helpful to social scientists who want to do educational studies about different styles of schooling in different populations.
