quoting further:
"This type of genetic make-up is usually found in the eastern Mediterranean which made us think that there might have been strong connections between north-east Wales and this part of Europe somewhere in the past.But this appears not to be the case, so we're still looking to find out why it's happened and what it reveals about the history of the region."
The article gives no explanation for why their original assumptions of 4,000 year old, Bronze Age -- think Stone Henge -- connections are now rejected.
Careful DNA analysis might suggest when those connections were first made, and this in turn provide the beginnings of understanding.
I would suggest that, without some solid evidence to the contrary, researchers should not automatically rule out Bronze Age.
There was more going on in those times than we really understand today.
