The first German colony

Here's DNA from the Battle Axe culture, in Scandinavia. It's a grave from 2500 BC but the culture dates back to 3000. The DNA is Ukraine - aka Yamnaya, aka IndoEuropean.

I'm intrigued that they just go ahead and call it Battle Axe Culture despite being aware of "Corded Ware". They don't seem to think that "Corded Ware" is a politicially-correct(?) euphemism. They consider Battle Axe to be the Scandinavian flavour of Corded Ware.

They also mention that the hunter-gatherers and the farmers are still loose in Scandinavia at the time. (They don't mention Finns at all... because those came later.) These groups "did not mix a lot", says co-author Mattias Jakobsson. I take it that battle axes could go only so far.
