More on migration and genetics

1 Jun 2020

At ... the early farmers that moved through the Balkans into eastern and central Europe did not mix with the local hunter gatherers it is thought. This could be as a result of rapid migration over long distances, moving  through the Danube valley into the northern European plain, However, in western Europe, when they  came up against a big obstacle, the sea, things seem to have changed. This is an interesting study as in France the hunter gatherers were faced by a two pronged assault by farmers. One that arrived from the east and another that was expanding along the coastline - particularly in southern France, and via Spain to as far north as Brittany. Here they have found considerable admixture with hunter gatherers. In southern France, as much as 30% of hunter gatherer genes were preserved. Admixture was also high in Spain, Britain and Ireland.
