With the recent papers about BB, Balkans and Portugal, a more clear picture about the people that spread the Megalithic culture in the Late Neolithic / Chalcolithic could be displayed.
The old Anatolian EEF wave linked to G2a seems passed away, and I2a clades take over Western Europe from Portugal or Britanny, delivering a 25% WHG to such pops.
It's quite interesting the possibility to link also GAC (Globular Amphora Culture) with such I2a wave: they were not using so much megaliths but instead pits and cists, but as their territory (RDA, Poland, west Ukraine) coincides greatly with that of the Funnelbeaker culture (TRB), and such culture provided the megalithism in north Europe, it could be though that the GAC pop had it's origin in such culture. By the way the collpase of GAC coincides with the apparition of the CWC and the R1a clades by 2900 BC.
