Well i think the two parts are pretty mixed now in most of Britain hence the confusion. It's only the edges: North Wales, the east coast of England and Scotland where it's easy to see the physical distinction.
Also it's probably more accurate to replace:
German -> North Sea
Welsh -> Atlantic Coastal (kinda Iberian but not precisely so)
so
North Wales = 1/4 North Sea + 3/4 Atlantic Coastal
England, South Wales, parts of Scotland = 1/2 North Sea + 1/2 Atlantic Coastal
Scotland = 3/4 North Sea + 1/4 Atlantic Coastal
not exactly or anything but something along those lines
(i think views are skewed by thinking of the "Celts" (Welsh, Irish, part the Scots) as all one group separate from the "Germanics" (English and part of the Scots) when it's obvious the Welsh are different.)
not so: as awhole England is more North-Sea I suppose, than Scotland
and as England, Scotland is (or WERE) variated according to regions - Scots (roughly said) have more Vikings imput but very less Anglo-Saxon-Frisian imput -
and when I spoke of Wales, even in Wales subregions were seen, wtih more blond hairs in central-eastern Wales (and as an hazard: more Y-I1! so surely more Y-R1b-U106)
Y-E1b in some points of North Wales is an exception we have yet to explain
I think precise studies of East Anglia and Centra England would show some autosomals differences too -
Belgae were not Germans, it's shown by their skeletons and the relative rupture in the Netherlands in the SNPs and STRs within Y-R1b South or North Rhine river - the less "germanic" qality of Southerners is evident - they have maybe a little bit more of 'north-sea' but not too much I suppose -
concerning autosomals of the 5 Hinxton people, analysis are not concordant for every small components and we are obligad to "translate" polings to polings but a sa whole
it is easy enough to tell between the 3 first ones: 389795/96/97 from the 2 last ones: 389798/99 (last: "celtic")
more North Sea or very more North Euro among "Saxons", more West-Euro, more Meds among "Celts"
what is a problem is the Eurogenes showing more Baltic among "Celts" (13,90 / 16,17 >< 6,42 / 3,38 / 7,00) AND less EastEuro (5,70 / 7,47 >< 12,73 / 8,57 / 12,41) but a total Baltic+East Euro equivalent (roughly said) when dv3 shows very less East-Euro among "Celts" -
but it's true 'baltic' is not 'eastern-euro': more ancient, more Hrs-Grs I think, 'eastern-euro' would have been reinforced by Indo-Europeans of later waves in Germanics AND/OR less erazed by Western autochtones... the 'baltic' (IF CORRECT) could have been picked up by first Y-R1b coming through North, or found in original Britain among females, by the Celt males? uneasy to tell - by the way, the "Atlantic" population was more a 'cromagnoid'-'capelloid' (mesolithic) + 'mediterranean' (not so heavy by Cardial agricultors, rather by maritime Megalithers) mix than a pure 'mediterranean' - but the Abglo-Saxons of subsequent centuries were maybe no more the "pure" Anglo-Saxons -
Coon shew some cemetaries in East England had more Anglo-Saxon males but a good hint of Breton females, and these Bretons at this times maybe too had some taste of other Europeans components after Roma Empire?
it is very exciting but we need more and more old DNA (as all of us know)
have a good Sunday
