|"Jan van Oostwoud" The Earliest Beaker Skeleton 575 (Fred Gijbels)|
One thing they comment on is that houses of the Beakers Complex continue in the traditions of those regions. Even when the genetic turnover was nearly total, such as in Britain, houses continue to be constructed as before.
I imagine this means that efficiency, building materials, and proven designs have a lot to do with house architecture rather than who builds them. Also, well built houses can survive hundreds of years, so it's not as if the wheel needs to be constantly reinvented.
Three more Beaker papers in the queue concerning population movements. Should have at least one tomorrow morning.
