1. Scandinavian data - Karlsson et al (2006) Eur.J.Hum.Genet. 14, 963-970.
We have: GOTLAND (2/40 = 5%), UPPSALA (1/55 = 2%), BLEKINGE (1/41 = 2%), VASTERBOTTEN (1/41 = 2%). This is based on the (reasonable) assumption that K*(xN,P) is all T & the contribution from any haplo L folks is small.
Earlier Jorgensen et al (2004) Hum. Genet. 115, 19-28 is where the Faroes and Danish data comes from: We find from their distribution map: FAROE ISLANDS (2/89 = 2%), DENMARK (3/62 = 5%). Also NORWAY (4/157 = 3%), ICELAND (2/181 = 1%), average for SWEDEN (9/110 = 8%), again based on that assumption. The results for Gotland and Sweden seem to reinforce the other data Wiki quotes for Malmo (1/29 = 3%) and Orebo (1/32 = 3%). Couldn't find the source of the Shetlands data but it does ties in with the Faroes.
2. The data showing very high levels in SOUTH GERMANY/BAVARIA looks genuine (4/17 = 24% - this extremely high level must be due to drift), from Pichler et al (2006) Human Biology, 441–464, and reinforces the data for Alsace (4/80 = 5%) and other data quoted in the region. I've not yet been able to find the source of Wiki's northern German data based on BERLIN (4/103 = 4%) or the HOLLAND (1/18 = 6%) and FLEMISH data (1/42 = 2% and 2/119 = 2%) but hope to hear from the moderators about that. I've been shown data from a Kurdistan led study showing significant levels of L299 in northern Europe (including Holland, Denmark and Lithuania) but that has not been published yet. And according to the Geno2 report I was given for L299 it describes significant levels also in Holland and England. So in all, the distribution map shown by Wiki seems reasonable. Our own subclade in England (based on the distributions of the surnames of folks we know who belong to our group) seem to follow an East to north west cline. In short, I think the Wiki map is OK, at least from a North European perspective.
Whatever, I think the otherwise excellent map on this page should be revised to take into proper account us Northerners.
To me, it seems from the evidence so far that the T's came into Europe via Anatolia, and one group headed through Greece and onto Germany and northwards to Scandinavia and Eastern Britain and northern isles, another group headed through Italy, Southern France (the proportions there seem overestimated) and Iberia. A further group headed from SW Asia northwards through the Crimea. Speculative at the moment but we await the full findings from Geno 2 with interest.
Of course I maybe just another old Northern European having a grumble!
