The autosomal make-up of Europe after the 2015 study

[curupira]

With the sequence of studies on ancient European remains, our understanding of the peopling of Europe has increased substantially. Initially Europe had Hunter Gatherers, on a West to East Axis (Mesolithic and before). Then came the Neolithic, which meant a pull towards the Near East. What exactly was this component is something still to be more investigated. We already know there was significant mtDNA and yDNA change, as well as autosomal change. The autosomal meant a pull towards the Near East. Then came the steppe invasion, which also brought R1b/R1a and the autosomal make-up of the Yamnayans (Eastern Hunter Gatherer + Neolithic, their own type of Near Eastern pull, Armenians being a proxy for that). With the steppe invasion, the WHG+EEF population of Europe was pulled, depending on the degree of Yamnaya input, towards the East. There are many more observations one can make. What else have you noticed?

I would really like DNA evidence from the pre historic Aegean, as well as from the megalith builders in Britain. We also need more ancient DNA from the near east. Im skeptical that R1a and R1b represent pure Northern lineages and only diffused Southward and Westward after 5000 BC. I know they were found in pure HGs from Eastern Europre dated to about 5500 BC but nearly all ancient DNA weve got now is from cold climates. The prehistoric Caucuses and Fertile crescent remain unstudied genetically.
