Genetic testing backs theory that Stone Age farmers spread widely in prehistoric times
Otzi the Iceman, an astonishingly well-preserved Neolithic mummy found in the Italian Alps in 1991, was a native of Central Europe, not a first-generation émigré from Sardinia, new research shows. And genetically, he looked a lot like other Stone Age farmers throughout Europe.
The new findings, reported Thursday here at the American Society of Human Genetics conference, support the theory that farmers, and not just the technology of farming, spread during prehistoric times from the Middle East all the way to Finland.
"The idea is that the spread of farming and agriculture, right now we have good evidence that it was also associated with a movement of people and not only technology," said study co-author Martin Sikora, a geneticist at Stanford University.
In what may be the world's oldest cold case, Otzi was pierced by an arrow and bled to death on a glacier in the Alps between Austria and Italy more than 5,000 years ago [...] MSNBC
Actualización 13-11-12. Los lazos genéticos de Ötzi con la población sarda (Cerdeña) ofrece indicios sobre la propagación de la agricultura en Europa
Ötzi, el "Hombre de hielo", una momia neolítica, sorprendentemente bien conservada, encontrada en los Alpes italianos en 1991, era natural de Europa Central, no un emigrante de primera generación procedente de Cerdeña, según un nuevo estudio. Y genéticamente se parecía mucho a otros agricultores de la Edad de Piedra en Europa.
Los nuevos hallazgos, proporcionados el pasado jueves en la conferencia de la Sociedad Americana de Genética Humana, apoyan la teoría de que los agricultores, y no sólo la tecnología de la agricultura, se extendieron durante los tiempos prehistóricos desde el Medio Oriente hasta Finlandia...

The "hunter-gatherers" from Götland and León are not even clearly hunter-gatherers.
La Braña (treated as composite of two very fragmented genomes) is borderline with Neolithic by date and the flexed burial is anything but typical "hunter-gatherer". It's dubious at the very least.
The Götland pig herders and fishermen of the Pitted Ware culture were Neolithic, even if from a regressive branch (because of their "frontier" lifestyle in the Far North), even Chalcolithic by time. Their likely ascendancy in Eastern European Neolithic however does make them likely related with Eastern European Paleolithic peoples because it would seem that Dniepr-Don and other less important Eastern European Neolithic cultures evolved locally with minor contact influences from outside. That would also make them closer with the Indoeuropean invaders of the Kurgan complex most likely and explain their relatedness to modern Northern Europeans.
As for Ötzi, I don't understand how they reached to such conclusions.
