Race not reflected in genes

“There is wide agreement among anthropologists and human geneticists that, from a biological standpoint, human races do not exist,” Sergio Pena and colleagues at the Universidade Federal de Minas Gerias in Brazil and the University of Porto in Portugal wrote in their report, published in the Proceedings of the National Academy of Sciences.

“Yet races do exist as social constructs,” they said. They found 10 gene variations that could reliably tell apart, genetically, 20 men from northern Portugal and 20 men from Sao Tome island on the west coast of Africa. But the genetic differences did not have anything to do with physical characteristics such as skin or hair color, the researchers found.
