    Eastern Baltic's first farmers and hunter-gatherers lived together, but apart

    It was not in all places where agriculture appeared, that local populations quickly noticed its benefits. In the areas from today's Lithuania to Finland, for about half a millennium, hunter-fishermen-gatherers lived alongside the first farmers, and these worlds merged very slowly, scientists' analyses show.
