The study itself is quite impressive, conducted with 160,000 people who agreed to allow their data to be used anonymously for research purposes when they submitted their DNA for analysis with 23andMe. Such huge sample numbers, which are “an order of magnitude bigger” according to an author of the study, allows for a much more thorough analysis than ever before, helping the authors produce a detailed geographical map of ancestry in the United States. Three major population groups considered in the study: African-Americans, European Americans and Latinos. Broadly, the genomic analysis found that on an average the African American genome was 73.2 percent African, 24 percent European and 0.8 percent Native American. Latinos as expected had significantly more Native American ancestry with the average Latino genome being 18 percent Native American, 65.1 percent European and 6.2 percent African. European American genomes is 98.6 percent European, 0.19 percent African and 0.18 percent Native American.….
