Our great big European family

Great Britain and continental Europe are just one, big family - at least genetically - according to a new study by Graham Coop, a professor of evolution and ecology at the University of California, Davis in PLoS Biology.

In The Geography of Recent Genetic Ancestry across Europe, Graham Coop writes that DNA studies show that, for the past 1,000 years, "everyone in Europe traces back to nearly the same set of ancestors."

"The overall picture is that everybody is related, and we are looking at only subtle differences between regions," said Coop who, with his co-author Peter Ralph, used the Population Reference Sample (POPRES) database, a resource for population and genetics research, to study 2,000 individuals for their paper.
