I love studying human migration - and our DNA is a very helpful tool in mapping out our own history. That said, it is only one tool among many and any good theory will be upheld through the application of diverse methods. In this context, genetic studies should in no way be read as indisputable or definitive proof of anything, they are simply one piece to the puzzle.
Yes. That.Also, something that no one has been able to explain to me so far is this.... Why would Gildas have lied and why didn't anyone call him on it if he was making it all up? And Bede writing 200 years later would have had access to the oral histories, so if it didn't happen why did he write it and why didn't anyone call him a liar? And if he was recording oral histories about the Anglo Saxon invasion that were actually around, but those histories were made up, why on earth would the Brits invent an myth about getting their asses handed to them by the Anglo Saxons for more than a generation?It just doesn't make any sense to me.
