Genetic Research for Croatia

Continuing to gather scientific research material about DNA origins of the people of the Balkans area, here are the results for Croatia. Published in magazine Nature - link.
"High frequency of haplogroup I in Croatian populations and the phylogeographic pattern in its background STR diversity over Europe make Adriatic coast one likely source of the recolonization of Europe following the Last Glacial Maximum."
This points that Adriatic coast may have been the only shelter from the last Ice Age, from which the colonization spread before the migration of nations from the East.

It is also interesting to see an interview with dr. Dragan Primorac, who participated in the study mentioned in the previous posts: http://www.nacional.hr/clanak/13956/hrvati-su-geneticki-najblizi-njemcima.

Map of Human Journey

Apart from well-known Atlas of Human Journey at National Geopraphic, here is one that is easier to follow and more graphically pleasing. From Bradshaw Foundation. See here.

More on Haplogroup "I"

Here is more information on haplogroup I, specifically I2 (link), that is the most concentrated group in the region covering today's Bosnia, Croatia, and Serbia.

Here you can see an overview of all haplogroups in Europe (link).

Genetic Study, continues

Here is more information about the HapMap project, mapping the genes of the world population:

SEE: http://slobodnadrina.blogspot.com/2011/03/haplogrupe-y-dnk-zastupljene-kod-tri.html
The most significant insight from these studies is, in my opinion (in Bosnian):

"Nedavno je objavljena najnovija studija kojom je dokazano da su nosioci grupe I zapravo autohtono evropsko stanovnistvo koje se prije oko 20.000 godina tokom posljednjeg ledenog doba bjezeci pred nadiranjem leda u sjevernoj i srednjoj Evropi, u najvecem broju povuklo u Bosnu i Hercegovinu i Dalmaciju
Podgrupa I1b sa mutacijom P37,2 zapravo predstavlja vecinu postojece grupe I. Ova grupa prisutna je u BiH sa prosjecno 52,4% prema rezultatu dobivenom tokom regionalnog istrazivanja. Slijedeci najzastupljeni nosioci ove grupe su stanivnici Hrvatske sa 32,4% i Srbije sa 29,2%. Udaljavajuci se od BiH kao epicentra izvora I1b haplotipa nalazimo ga i u Sloveniji 20%, Makedoniji 34,7%, Grckoj 8,4% i Kosovu 7,9%. Van naseg regiona druge linije grupe I takoder se u znacajnoj mjeri pojavljuju u Norveskoj, na Sardiniji i oko Crnog mora."
and
"Relativno niska zastupljenost slavenskog genotipa u BiH zapravo je najvece iznanadenje ovog istrazivanja."

A Response to a Video on Genetic Origins of Croats, on YouTube

This is a response to a video "PORIJEKLO HRVATA(najnovija genetička istraživanja) !" on YouTube. Since the reply box there does not allow as much text, I decided to write a response here.

I can't find any links to relevant studies that support what you state here. If we are to believe the genetic research from the past several years (that's what is said in the video) then why list so many books when you, yourself, have said that books are not to be trusted?
Also, why was it easier to assimilate to tens of thousands of words from Slavic vocabulary than to keep more than one thousand of those of German origin?
These things make no sense and I see no link to a relevant study that would support different point of view.
Another dubious statement is that all the I haplogroup in Bosnia comes from Herzegovinian Croats. In 1991 census, about 17% of Bosnian population were Croats. How is it possible that genetic studies (http://mbe.oxfordjournals.org/content/22/10/1964.full) show that circa 60% of Bosnian population has I haplogroup?
I, personally, can't accept posts from public wiki where authors are "Istrazivac", "CHM8318", "Dadas", "Hu1", "Yoshamya", "Cesljugar", etc. While these people may have background knowledge, the material should have references to scientific texts, of which there is none on the linked page.
Just my $0.02 on the topic.

More on Genetics - iGenea Forum

There are more studies on genetics of the people in the Balkans peninsula. Too bad I can't find the results of DNA tests on iGenea site anymore. Seems it is not available there.
However, there is a discussion at iGenea Forum - Bosnia,
and also another study - "The peopling of modern Bosnia-Herzegovina: Y-chromosome haplogroups in the three main ethnic groups" - from U.S. National Library of Medicine, National Institutes of Health.
What these results show is quite interesting. Today's nations in the Balkans region (and probably most other places on Earth) are based on religion, mostly, as well as some characteristics of societies from 19th century, like language, customs, appearance, history, etc.

Illyrian Identity

A very interesting way to look at the identity of Illyrians, below. Seems quite similar to how most nations in the Balkans area feel about themselves today.
In general, the Illyrians have tended to be recognized from a negative standpoint in that they were manifestly not Celts, Dacians or Thracians or Greek or Macedonians, their neighbours on the north, east and south respectively. (John Wilkes, The Illyrians, p3)

Phylogenetic Analysis of Southeastern Europe

The results of a phylogenetic analysis from 2005 display the paternal gene flow among Balkans population. Shed interesting light on the origins and the relations between population.
