What does modern Genetics have to say?
High quality genetic analysis is expanding at a record rate today and from it we might expect to find out much about peoples of the past. New information is being added too quickly to declare any one set of data or analysis "established fact" or "the final word".
This dogmatic article appears comprehensive and authoritative, but without an extensive and detailed bibliography it is impossible to determine what is fact and what is wishful thinking. With that caveat, it is interesting reading. When solid scientific genetic research appears it can then be compared.
