genetic variation in Africa is structured geographically, and to a lesser extent, linguistically. The findings are consistent with the notion that populations in close geographic proximity that speak linguistically similar languages are more likely to exchange genes.
Furthermore, genetic variation in Africa appears consistent with the natural, geographic barriers that limit gene flow. In particular, there are geographic, and therefore genetic, distinctions between northern African and sub-Saharan African populations due to the vast desert that limited migration.
"Focusing on particular exceptions to these broad patterns will enable us to discern and fully appreciate the complex population histories that have contributed to extant patterns of genetic variation," said Tishkoff, the David and Lyn Silfen University Associate Professor. "Disentangling past population histories is a formidably complicated task that benefits from the synthesis of archaeological, linguistic and genetic data."
