Dienekes alerts us to a new study about Paleolithic and Mesolithic Europeans:
http://www.dienekes.blogspot.com/2015/03/ice-age-europeans-on-brink-of-extinction.html
"In some cases, small bands of potentially as few as 20 to 30 people could have been moving over very large areas, over the whole of Europe as a single territory, according to Professor Ron Pinhasi, principal investigator on the EU-funded ADNABIOARC project.
Prof. Pinhasi’s team has found that the genomes sequenced from hunter-gatherers from Hungary and Switzerland between 14 000 to 7 500 years ago are very close to specimens from Denmark or Sweden from the same period.
These findings suggest that genetic diversity between inhabitants of most of western and central Europe after the ice age was very limited, indicating a major demographic bottleneck triggered by human isolation and extinction during the ice age. "
Also, "
This demographic model is based on new evidence that suggests populations were much smaller than is generally thought to be a stable size for healthy reproduction, usually around 500 people. Such small groupings may have led to reduced fitness and even extinctions. "
Was it in Loschbour that they found some real problems in terms of fitness?
Isn't there a major issue in the fact that there are no results from southeastern Europe? I know the Bean project was supposed to be doing this, but the only paper of which I'm aware is the Sandra Wilde paper on pigmentation. Do they have dibs on that area? Couldn't Reich and co get their hands on some specimens?
