Not surprisingly, the first four components (North Sea, Atlantic, Baltic, Eastern Euro) appear to form a cluster (their correlations are all positive). And the West Asian, East Med, and Red Sea components appear to form another cluster.

The highest correlations are as follows:

North Sea with Atlantic - 0.82907
East Med with Red Sea - 0.738665
North Sea with Baltic - 0.685673
Eastern Euro with Baltic - 0.658021
Atlantic with West Med - 0.613203

With the ancient dna results I've seen, the North Sea with Atlantic mixing would seem to have occurred relatively recently, while the East Med with Red Sea correlation might have been there for a longer time. Most of the Neolithic Farmers were highest in the West Med component, with the Atlantic and East Med components also being high, along with smaller amounts of Red Sea. While the Western Eurasian HGs seem to have been overwhelmingly from the first four components, with often some Amerindian and traces of others such as South Asian and Oceanian. And of those Western Eurasian HGs, the Atlantic component tended to be smaller, especially for the non-Western European ones - although strangely, the oldest ones (Ust'-Ishim and Kostenki 14) had a good share of the Atlantic component.

Part, what is now Atlantic component, came from East with Bronze Age migration.

Part, what is now Atlantic component, came from East with Bronze Age migration.

So what you're saying is the Atlantic component could be broken down into two parts, with one part coming from the East during the Bronze age?

If so, I suspect the Bell Beakers had both of those components. The average of the Atlantic component for the 7 Bell Beaker samples is 27.08% from this spreadsheet: https://docs.google.com/spreadsheets...#gid=917906623 That's nearly as high as what it is now in the Atlantic coast countries.

What cultures could've the Atlantic Haplotype been involved with?

[MOESAN]

i think the most typical ancient 'atlantic' was made of some WHGs DNA + the double of early people closer to West-Med (neolithic part of EEF) - a small part only came from East, later, mediated by the some bearers of dominant 'north-sea' -
the proximity 'atlantic' to 'north sea' could be a symetric flood of two directions osmosis not erasing the first great enough distances, but diminshing it, WITHOUT FORGET the common original WHG (we find too in 'baltic' -
the little part common between today 'atlantic' and ancient skeletons DNA of Eurasia and Siberia is AN OLD INHERITAGE (ancient >> young, of course!)
almost ALL the today componants we pooled are heirs of these previous men, at some level or another so we find nowaday parts of this ancient DNA inequally legated, but we LABELL IT 'atlantic' or 'south-asian' or 'X' according to the geographic populations where we find them concentrated today -
