Northern Europeans Differ from Southern Europeans

[Anthropologique]

Only 5,700 SNP's ? Sorry but that's crap. Dodecad or Eurogenes use hundred of thousands of SNP's. In the last v3 run used 166.000 SNP's.

I started to laugh when I saw the tiny number of SNPs utilized. And they call themselves scientists?

Seems us armchair internet anthropologists already know more than these scientists. Europe's genetic origins are much more complex than a mere north-south cut - the majority of populations contain little minorities of the others, except for Scandinavia which doesn't seem to have any SE - but then again they have other inputs like Baltic and Eastern European.

Maybe because the text is from 2006?

There are a few Norwegians who have 20% Mediterranean admixture on Dodecad.

Isn't this topic a little outdated...moving on

Yeah, unfortunately the tools we have available right now don't have a sufficiently large sample population. Things will become more clear when that increases over time.

[South Europa]

5,000 SNPs is plenty to give a solid picture of genetic structure. It was more than enough obviously just being able to seperate an extremely homogenous continent like Europe. Just 6 years ago that kind of data was not even available.

However, newer studies are being based on hundreds of thousands of SNPS..which can further separate the North and South of Europe..genetically.

In the Seldin et al study the original topic starter brought up, it shows North and Central Europeans forming one major genetic block, and Southern Europeans and Ashkenazi Jews forming the other one.

In this newer study by Tian et al. from 2008 based 300,000 SNPs showed that we can distinguish even those two genetic blocks.

European population genetic substructure was examined in a diverse set of >1,000 individuals of European descent, each genotyped with >300 K SNPs. Both STRUCTURE and principal component analyses (PCA) showed the largest division/principal component (PC) differentiated northern from southern European ancestry. A second PC further separated Italian, Spanish, and Greek individuals from those of Ashkenazi Jewish ancestry as well as distinguishing among northern European populations. In separate analyses of northern European participants other substructure relationships were discerned showing a west to east gradient.

Because that study didn't have French people, who are a bridge between southerns and germanics. There is not a separation between south and North, what there is a continuum.

— ... And as usual, the French are left in the middle of nowhere

It all has to do with France's geographical location.
