They are the opinions or best guesses of the authors and should be independently verified by serious researchers. Placing of individuals into a color-coded group does NOT mean that their lineage to a certain ancestor has been verified or that our placement is absolutely correct. It means that the person tested has a verified DNA match with another person with the same color code.
