““Using a 500,000 snip chip, researchers at Stanford University have found a strong correspondence between the genetics and geographical origins of Europeans. In fact, 90% of people can be located to within 700 kilometers (435 miles) of where they were born, and 50% to within 310 kilometers (193 miles). Europeans are fairly homogeneous at the genetic level, so it is quite surprising that enough genetic differences exist among them to infer a person’s origin so precisely.””
