Some other interesting bits:
"Comparison of British Mesolithic samples to different Mesolithic WHGs (Loschbour -Luxembourg, La Brana - Spain, KO1 - Hungary; Supplementary Figures S5-S6) indicatesthat they all resemble Loschbour most closely (i.e. the geographically most proximateMesolithic genome available)."
"The majority (~75%) of ancestry in all British Neolithic individualscould be attributed to ANFs."
"individuals from Wales retain the lowest levels of WHG admixture, followed bythose from South-West and Central England. South East England and Scotland show thehighest WHG admixture proportions. These proportions remain stable for over a millennium,from the Early into the Middle/Late Neolithic."
"For all of our BritishNeolithic individuals we inferred more shared drift with Early Neolithic Iberians; for themajority of comparisons this was significant (Figure 4A, Supplementary Figure S9). To inferlevels of WHG introgression occurring between Iberian Early Neolithic populations – theclosest currently available attributable source of farmer ancestry in British Early Neolithicgenomes – and early British farmers, we estimated f4 admixture proportions. We detectedlittle excess (~10%) WHG ancestry beyond what was already present in Iberian EarlyNeolithic populations, suggesting small proportions of admixture, particularly in Wales wherewe detected no excess WHG ancestry (Figure 4B)."
Based on the correspondence we saw, the results are slightly different than stated below, aren't they? Did they waffle because of the controversy?
"here we integrate 36 rather than 2 SNPs allowing more preciseprediction26. Cheddar Man is predicted to have had dark or dark to black skin, blue/greeneyes and dark brown possibly black hair, whereas Sven most likely had intermediate to darkskin pigmentation, brown eyes and black possibly dark brown hair (see Pigmentation sectionin the Supplementary Materials for a detailed discussion of the results). This is in line withthe current hypothesis that alleles commonly associated with lighter skin were introduced inWestern Europe by ANFs19."
"We also analysed two previously-published WHGs, and find potential temporal and/orgeographical variation in pigmentation characteristics. Loschbour22 from Luxembourg is~2000 years younger than Cheddar Man, and is predicted to have had intermediate skinpigmentation. Furthermore, the Loschbour individual most likely had blue/green eyes. Incontrast, La Braña18 from northern Spain who is slightly later than Loschbour is predicted tohave had dark to dark to black skin and hazel/green eye colour. Both La Braña andLoschbour were predicted to have had black, possibly dark brown hair. These results implythat quite different skin pigmentation levels coexisted in WHGs at least by around 6000 BC."
"British farmers were substantially descended from Iberian Neolithicrelatedpopulations whose ancestors had expanded along a Mediterranean route2,7,14,although our analyses cannot rule out the possibility that they also inherited a minorityportion of their ancestry from the Danubian route expansion through Central Europe. Indeed,a recent study that investigated continental Neolithic farmer-related ancestry components inNeolithic Britain estimated ⅔ Mediterranean and ⅓ Danubian route8, which may beconsistent with the association between Britain’s more easterly-distributed Carinated Bowltradition14 and the Nord-Pas-de-Calais region of France, as Neolithic people in these regionsof mainland Europe are thought to have interacted with populations of Central EuropeanNeolithic ancestry."
We have pointed out the following on this site:
"We caution that our results should not be interpreted as showing the Iberian Neolithic-relatedancestry in British Neolithic people derives from migrants whose ancestors lived in Iberia, aswe do not have ancient DNA data from yet unidentified source populations — possiblylocated in southern France — that were ancestral to both Iberian and British farmers."
I thought prior British Neolithic samples were closer to Italians than anyone else, yes?
"The limited regional variation in WHG ancestry we see in the British Neolithic samples couldreflect subtle but differing degrees of regional admixture between farmers and foragers,and/or multiple continental source populations carrying varying levels of WHG ancestrycolonising different regions of Britain. What is clear is that across Britain all of our estimatesfor admixture between hunter-gatherers and farmers are very small, and that we find noevidence of WHG ancestry increasing as the British Neolithic progressed over time."
