His history is bunk – the Anglo-Saxons have only been here for some 1500yrs, the original hunter-gatherers only arrived circa 11'000-10'000yrs ago.
Muddy Dwarf- your history is also 'bunk'
the original hunter gatherers arrived c500,000 BC (boxgrove)
And there is a fair arguement that suggests the anglo-saxon invasion' was not quite the invasion we imagine. Certainly not really enough to change our ethnicity. For example less than 2% of graves in early 'anglo saxon' burial grounds contain people from Germany (tooth anaysis) and of this 2% a sigificant number are female.
My point is that we are already a genetic mix even DNA (currently) cannot even tell northern europeans apart.
Also if the celts 'arrived' who was here before..?
