Y-DNA Haplogroup Distributions

[Erik]

In internet I read a lot of articles about the origin of the haplogroup R1b.
Does anybody read the website: peoplingeurope?
Some years it was thought that haplogroup R1b has
its origin in southwest France, because most Basks, inhabitants
of the Iberian peninsula and of the British Islands have R1b.

Now it has been discovered that R1b has an origin in Anatolia
about 20.000 years. About 5000 BC it dispersed from north of
the Kaukasus to West-Europe. Especially the Celts have the
haplogroup R1b.

Many thanks for your information. But I cannot understand why most
of R1b live in Spain and Portugal and have very dark hair! And see
fair and red haired Dutch and Danes.

Another questions: do you know something about the haplogroup of I,
very frequent in original Germanic ares such south Sweden, Denmark,
North Germany and Frisia?

First all, Y-DNA of course does not define ethnicity as a whole. But if all your ancestors come from a same region (Sweden or Denmark), knowing the Y-DNA frequency in that region might give you important clues about a part your own genetic history.

The study of Y-DNA is highly important for our understanding or history and migrations, or even linguistics.

The most recent common ancestor (MRCA) of I1 lived from 4,000 to 6,000 years ago somewhere in the far northern part of Europe, perhaps Denmark, according to Nordtvedt.

His descendants are primarily found among the Germanic populations of northern Europe and the bordering Uralic and Celtic populations, although even in traditionally German demographics I1 is overshadowed by the more prevalent Haplogroup R.

It has to do for the high density area where it originated, the Proto-Germanic culture, during the last period of Nordic Bronze age.

@Branvinn what is the source of that I1 map? East-Scotland is as dark as Denmark and Norway, and it is very different than the one from Genetic Atlas?

I would caution against either tide right now. The pendulums on these things always swing. The Peopling of Europe site is over-hyped in my opinion and I see it as unwise to make sweeping proclamations in any direction.

As fas as I know, none of the major population geneticists have announced any change in their tunes regarding the age of R1b.

In other words, let's wait & see.

My money is on a late European Paleolithic or Mesolithic origin of R1b.

This one seems to be much better, also showing the I1(a) influence in Russia, presumably from Varangians, the other map looks rather faulty:

Yours is the one based upon Rootsi et al. Anyway it is still one of the best maps, nicely shaded per 5%:

Hg I1a from Rootsi et al (2004).

I did a little search and found what seems to be the latest I1 map of Europe (Balanovsky et al 2008):

Concerning Branvinn's map, here is the comment of the creator of that map. Though it seems to be based upon Rootsi and Balanovski, it is still strange that Scotland and Ireland are so dark?.

Please note that this image is an artistic interpretation of scientific data.

I created this map using information from genetic testing results from various companies. I used Photoshop and the GIMP.

Among the studies I used as reference were:

From the Wikipedia, I think that is from the study of professor Ken Nordtvedt.

Another one above, distribution of I1 and I2, Sweden and Norway have both, the high concentration of I1 while Croatia and Bosnia of I2.

I don't get this map either?

It is created by a someone named Hxseek (:rolleyes:)
He seems to have completely left out the 30-40% range if I see his legenda on that map....:p

This is the original from Rootsi et al (http://evolutsioon.ut.ee/publications/Rootsi2004.pdf), were he says this example is based upon (:p):

What are the main differences (rhetorical)?

[Agrippa]

I know it might be purely coincidal, but I always wondered how close I1(a) can be related to Skandonordid and I2 to Dinaroid in Europe. Its really fascinating and in this paper mentioned too (I know its not about the racial type, yet the centres and distribution are pretty close to what can be said about the Dinarid type):


The phylogeography and high associated variance of I-M170
is consistent with an in situ European origin of M170 in
the Balkans (Semino et al. 2000a), possibly near the Dinaric
Mountain chain in Croatia where it has been observed
at the highest frequency known so far (Barac et al.
2003). I-M170 lineages radiated both towards north central
Europe and into western Turkey. Comparison of STR
haplotypes indicates that the Dinaric modal haplotype is
associated with the I-P37 lineages observed in Turkey.

It just doesnt overlap further West, in the German areas - probably due to Germanic male dominance if there would be a correlation of some kind? Such correlations, and be it by chance, make me speculate...

For who is interested more about, here a nice source;

Those maps are not very accurate. Western Finland has on average 40% I1a, in Satakunta over 50%. And in Eastern Finland it's still around 20%.

This thread title is not very accurate either.. :p
