BBC reports that researchers have kicked off a project aiming "to link the migration of men in the Bronze Age to the discovery of copper" -- for which they'll need DNA samples to help trace the predicted trail of Mediterranean people to northwest Wales some 4,000 years ago. "The researchers are building on previous work carried out in the area which found a much higher-than-average presence of a DNA marker that is commonly found in people from the Balkans and Spain," the article says. The scientists are looking for hundreds of men born around the region in Wales whose paternal grandfathers came from the same area.
