Yeah we are obviously westerners and genetics show it.
Also...
It is possible... not too sure. I do know that the Atlantic admixture appears to be a hybrid of Mesolithic hunter-gatherers and Neolithic farmers. All Mesolithic and Neolithic samples from Western Europe had about 25% of it.
Prehistoric samples Atlantic admixture:
Mesolithic La Braņa (Asturias, Spain) 27.3%
Mesolithic Loscbour (Luxembourg) 29.5%
Neolithic farmer from Stuttgart (LBK culture) 23.2%
Ötzi the Iceman (Chalcolithic farmer from the Alps) 25.5%
Gökhem2 (Swedish Neolithic farmer) 27.7%
Motala12 (Mesolithic HG from Sweden) 10.1%
You can see the so-called Atlantic fusion peaks in the Basque and neighboring communities, accompanied by the Irish, Welsh and Scottish. But apart from that, it's really not centered on the Atlantic. The Galicians have less of this than the Danes and North Germans. High frequency in Sardinia, but much lower frequency in southern Italy and the Balkans, indicates a Mesolithic Western European ancestry.
