 Before extensive studies of the distribution of R1b Y-DNA subclades, some previously maintained that native Britons were displaced by the invaders.This idea has been discarded in the face of evidence that much of the population has, at the latest, Hallstatt era origins, but probably late Neolithic, or at earliest Mesolithic origins with little contribution from Anglo-Saxon source areas.However, by AD 500, the land that would become Wales had divided into a number of kingdoms free from Anglo-Saxon rule.
