Срећна слава свима који данас славе!

Чини ми се да ови резултати одговарају онима из Српског ДНК пројекта.

У Херцеговини фасцинантних 63.83% I2a хаплогрупе. Ова хаплогрупа је такође присутна у високом проценту међу Херцеговцима у Српском днк пројекту.

R1a је код Херцеговаца заступљена са 12.06%, што није мало, али је ипак осетно мање него код Хрвата или нпр. Словенаца.

Срби генерално имају више R1a (15.9%) од "Херцеговаца", али мање од Бошњака и Хрвата.

Интересантно да код грчких Македонаца постоји висок проценат R1a.

Проценат I1 такође одговара оном из нашег днк пројекта. Код Херцеговаца и Срба око 5, 6%. Занимљив је и висок проценат ове групе код косовских Албанаца (5.31%) и Македонаца (5.06%).

Видели смо да ова хг заиста постоји код неких родова из албанског днк пројекта и са 23andMe.

E1b је прилично заступљена код Албанаца са Косова. Код Срба релативно висок проценат - 19%. Слично је и у днк пројекту.

R1b се најчешће јавља код косовских Албанаца, чак 21.10% ("балканска" грана) и код Хрвата 15.70% ("западна" грана?).

О блаканском R1b знамо већ доста и стога не чуди висок проценат код Албанаца. Чини се да се резлутати R1b Хрвата не косе се онима из днк пројекта, зато што на западу Хрватске постоји велики број R1b родова.

J2b-M241 постоји у већем проценту једино код косовских Албанаца (16.70%).

J2b, која није M241, може бити само M205, или евентуално J2b која није ни M241, ни M205 (али она је веома ретка).

Судећи по резултатима, J2b-M205 је заступљена код Срба са 4.40%. Код Хрвата и Бошњака не постоји, али је зато има код Македонаца (2.50%), што се на основу досадашњих резултата није могло закључити.

М205 се и у српском днк пројекту креће око 5%.

--- Цитат ---We generated new genome-wide data from 204 ancient humans, from the Balkan Peninsula, the Carpathian Basin, the North Pontic Steppe, and neighboring regions mostly dated to between 12,000 and 1000 BCE.

Results
Hunter-gatherers from central Europe have both western and eastern European hunter-gatherer ancestry (WHG and EHG)

From present-day Ukraine, our study reports new genome-wide data from 31 hunter- gatherers: five Mesolithic individuals dating from 9500-6000 BCE, and 26 Neolithic and Copper Age  individuals dating from ~6000-3500 BCE. On the cline from western to eastern hunter-gatherer ancestry the Ukrainian Mesolithic individuals fall towards the eastern end, intermediate between EHG and hunter-gatherers from Sweden7. The Ukrainian Neolithic population has significant differences in ancestry compared to the Ukrainian Mesolithic population; ANE ancestry decreases and WHG ancestry increases.

Individuals associated with the Bronze Age Yamnaya Complex from Ukraine, have little evidence of WHG  ancestry, but do have a third source of ancestry related to hunter-gatherers from the Caucasus (CHG) and early Iranian farmers .

Two Yamnaya individuals – one from Ozera in Ukraine and one from Bulgaria ( both dated to ~3000 BCE) – in addition have evidence of early European farmer related admixture, which is the first evidence of such ancestry in Yamnaya individuals. Similarly, one Copper Age individual dated to ~3600-3400 BCE from Dereivka in Ukraine has both CHG and farmer ancestry. This is by far the earliest appearance of farmer ancestry this far East in Eurasia, which was previously not known on the Steppe until the Srubnaya Complex after ~1800 BCE.

In the Baltic States  we find that Mesolithic and Early Neolithic individuals associated with the Kunda and Narva cultures had ancestry that was genetically intermediate between western and eastern hunter-gatherers (we estimate 70% WHG and 30% EHG). However, there is a dramatic shift between the Early Neolithic and the Middle Neolithic Comb Wear Complex,  who are almost entirely EHG in ancestry (we estimate 73% EHG, but two out of four individuals appear almost 100% EHG in PCA space).

The Sicilian and Croatian individuals dating to 12,000 and 6100 BCE cluster closely with western hunter-gatherers. These results demonstrate that the “western hunter-gatherer” population was widely distributed from the Atlantic seaboard of Europe in the West, to Sicily in the South, to the Balkan Peninsula in the Southeast, for at least six thousand years, strengthening the evidence that the western hunter- gatherers represent a population that expanded from a southeastern European refugium following the last Ice Age around 15,000 years ago–in the process displacing or admixing with the existing population of western Europe.

A particularly important hunter-gatherer population that we newly report in this study is from the Iron Gates region that straddles the border of present-day Romania and Serbia. This region is close to the route taken by farmer migrants on their way from the Balkans to central Europe, and the population is represented in our study by 35 individuals from the Iron Gates sites of Hajdučka Vodenica, Ostrovul Corbului, Padina, Schela Cladovei and Vlasac, one individual with similar (but more EHG) ancestry from the Early Neolithic site of Măgura Buduiasca , and two individuals with farmer ancestry from the Mesolithic-Neolithic site of Lepenski Vir. Modeling Iron Gates hunter-gatherers as a mixture of WHG and EHG shows that they are – as expected given their geographic location and the hunter-gatherer ancestry cline  – intermediate between WHG (87%) and EHG (13%). However, this qpAdm model does not fit well  and we note that the Iron Gates hunter-gatherers  carry mitochondrial haplogroups K1 (8/36) as well as other subclades of haplogroup U (27/36) and haplogroup H (1/36). This contrasts with WHG, EHG and Scandinavian hunter- gatherers who almost all carry haplogroup U5 or U2. Therefore the Iron Gates hunter- gatherers have ancestry that is not present in WHG or EHG. This suggests either genetic contact between the ancestors of the Iron Gates population and hunter-gatherers from Anatolia, or that the Iron Gates population is related to the source population from which the WHG split off during a post-LGM re-expansion into Europe.

Neolithic populations from present-day Bulgaria, Croatia, Macedonia, Serbia and Romania cluster closely with the Neolithic populations of northwestern Anatolia. Modeling Balkan Neolithic populations as a mixture of Anatolia Neolithic, western hunter-gatherer and Ukraine Mesolithic, we estimate that Balkan Neolithic populations derive 98% of their ancestry from populations related to those of the northwestern Anatolian Neolithic. A striking exception to the pattern of limited hunter-gatherer admixture in Balkan Neolithic populations is evident in 8 out of 9 individuals from Malak Preslavets, a site in present-day Bulgaria close to the Danube river. These individuals likely lived in the mid-6th millennium BCE and have significantly more hunter-gatherer ancestry than other Balkan Neolithic individuals.
