Just a gut feeling, Mike. I know the Celtic groups occupied bands in
Ireland that stretched across the country, and the "Eoganacht" band
even went across to Wales. Behaviour tells me that there might have
been a similar human pattern even earlier. I think they may have used
the ice or the edge of the ice to travel across bodies of water giving
them a e-w or w-e migration along the north, and then slowly moved
south. We see a greater density all along the northern areas and less
as we go south. As the ice retreaed, there would have been ample
water, game and areas glacially cleared of trees for agriculture and
grazing. Sounds ideal to me.
