A subclade of I2a1 called I2a1b2a1, defined by SNP CTS10228, shows a very strong correlation with the distribution of Slavic peoples. Moreover, the time of most recent common ancestor (TMRCA) for males carrying this subclade, is estimated by YFull as just 2200 years ago (ybp), shortly before Christ:

I'm not sure what percent of entire I2a1 in Europe belongs to I2a1b2a1 - but surely in Slavic and neighbouring countries it is the majority. I guess, that at over a dozen million males carry this subclade (while in total all subclades of I2a1 are carried in Slavic countries by an estimated 20 million males and in neighbouring countries by another close to 6 million). Some of the most basal subclades of CTS10228 as well as CTS4002 were found in Polish people.

This sample (Y-Full number YF03513) is from Świętokrzyskie Voivodeship (SK) in Poland (PL):

I-CTS4002* - id:YF03513 POL [PL-SK]

In FTDNA this kit has identification number N113464, it belongs to a male from Moskorzew:

Another basal sample from Poland is from Subcarpathian (Podkarpackie = PK) Voivodeship:

The route from haplogroup I2, via I2a, I2a1 (P37), I2a1b2 (L621) up to this very young but very numerous I2a1b2a1 (CTS10228):

Here a map showing the distribution of I2a1b2 (L621):

Vast majority of L621 is also under CTS10228, while men with more basal subclades of L621 are relatively few:

Here an alternative map of I2a1b, but a very old one (from O. Balanovsky 2008):

At that time I1b was the name for what is today known as I2a1b (M423):

In Ukraine about 20.5% - 22% of all males are carriers of I2a1 - probably great majority of them belong to subclade I2a1b2a1:

According to Kushnierevich 2013, in the region of Polesia (Belarus-Ukraine borderland), 26% of males (56 out of 217) carry I2a1.

In Russia over 1/10 of men carry I2a1. In Slovakia - ca. 1/6. In Czech Rep. - ca. 1/10. In Slovenia - as many as in Ukraine (over 1/5). In Macedonia - up to 1/4. In Serbia - ca. 1/3. This marker correlates with Slavic people just as strongly as R1a, in some regions even more strongly:

According to Y-Full, this subclade formed already 5500 years ago, but existed in very marginal numbers throughout the next 3300 years (ca. 130 generations) - starting a more serious demographical expansion only around 2200 years ago (TMRCA according to Y-Full). I suppose, that between 5500 ybp and 2200 ybp, carriers of this clade lived as a small group of people in the region of Polesia (also known as the Pripet Marshes), which most likely was a kind of refugium for them. Only around year 200 BC they probably started moving out of Polesia, and started to increase in numbers, mixing with neighbouring R1a groups and forming the Proto-Slavic community (who then started their famous expansion several centuries later).

Today frequency of I2a1 is still higher in Polesia (ca. 26%) than in neighbouring regions of Belarus (ca. 17%) or Ukraine (ca. 20%).
 
Here is a current rendering of my genetics that are located in the heart of the geographical area you describe. FTDNA has cts10228 as my terminal clade. YFull S17250+ and Y4882*

It doesn't look particularly West Slavis. Either West Slavs come from a different tribe, with very low level of L621 or West Slavs are Slavicized locals.

Great and informative website / blog Singingfalls, thank you!

Probably from a different branch / tribe of Slavs, with less I2a.

But all Slavic groups assimilated (Slavicized) some locals as well.
 
I've just a modest theory: Y-I2a1b was present in all Balkans and Carpathians and it bearers for the most were pushed or retrated at first Neolithic people arrival into mountainous regions. In West (Dalmatia, Dinaric Alps, for the most) they lived longer at the mergins of newcomers, staying in little numbers. in East, they were progressively acculturated (when?) and took some profit of the Tripolye Cucuteniculture before being incorporated in the Slavs culture,underrunning a strong demographic development after sedentization of these Slavs. I think they could have worked in the separation of Slavs and Balts. Czechs and Yugoslavs (and Bulgarians) are "less" slavic in origin, spite showing distinct history one from another.
 
FTDNA data base has confirmed my terminal SNP to be I-A7358. Updates here: http://www.singingfalls.com/dna.html#ydna_updates There are three individuals in the database currently with this SNP. It is also listed in the Slovakia-DNA and carpatho-rusyn groups.
 
See my post #137 at "I2a-Din came to the Balkans and Dinaric Alps with the Thracians, Dacians & Illyrians" or #1189 at "How did I2a-Din get to the Balkans?" where argued that the age of formation and TMRCA of I-CTS10228 and I-S17250 does not correlate with consideration that it survived since the Chalcolithic only in area of Poland- Belarus-Ukraine, the ethnogenesis of the Slavic people, Slavic expansion in Eastern Europe i.e. migration from Eastern Europe toward Balkan between 550-750 CE.

The L621 map suggests that the origin was in the Dnepr-Dnestr-Pontos area, from where it spread in all directions. When a part of it came to the Adria as a bareer, this clade accumulated there by means of continued immigration of this tribe. If the map is 'right' STR data should be able to prove a cline of L621 diversity between south-western Ukraine and the west balkan.

West-Slavs are genetically only to a smaller degree real Slavs. Being dominantly of the M458 clade they were slavisized during the expansion in the first millenium AD.
 
What do you think caused this lineage to expand so rapidly after 3000 years of insignificance ? I had a theory but was immediately ridiculed for it in some other thread I started, which is Elite dominance, whoever this guy was that most modern I2a1b2a1 descend from, He had a lot of male offspring, and his descendants had a lot of male offspring themselves, they probably practised polygamy for this rapid expansion to become possible, they were not your average simple peasant, he was definitely a king of some sort, someone important, maybe ruling a majority R1a tribe that spoke proto-Slavic, this lineage would have been the forefather for many Slavic dynasties in their future expansions.

This, and keep in mind that Balkans were quite depopulated in Dark Ages, so it was easier for a small group to experience unrestricted and fast growth, when better times presented themselves.

Do you have a genetic sample of proto-Slav to be so sure of your conclusion?

Well, I mislaid my time-travelling machine, so I can't fetch you the proto-slav sample (if such people even ever existed...), but as an educated guess the R1a-makeup of peoples/nations with westslavic languages may suffice.

In this table you have
...the Poles (Поляки) with 26.2% (= 17.2% L260 and 9.4% M458xL260) of M458 vs. the whole Z280 clade of 26.8%
...the Czech (Чехи) with 22.3% (= 11.7+10.6) of M458 vs. 15.0% Z280
...the Sorbs (Лужичане) with 56.9% (= 33.3+23.6) of M458 vs. 8.3% Z280.
I don't have data for Slovaks, but the Family Tree site lists about the same amount of M458 to CTS1211, not a strong evidence with such biased data, but at least a hint on the direction.

Not sure where you came to that conclusion considering R1a m458 is pretty distinctively more common in Slavic populations and not in non Slavic nations. Auch eine lustige Bemerkung von einem Österreicher . Ihr habt so viele slawische Herkunft, dass manchmal frage ich mich wie ihr nicht eine slawische Sprache spricht. R1a erreicht fast 40 Prozent der Bevölkerung in Steiermark und die Hälfte von Wien haben alle tchechische Nachnamen.
 
Slovakia has pretty high rates of I2a and besides Ukrainians probably has the highest rates from all north slavs. Eastern Slovakia especially. My guess is there were two sort of Slavic groups living next to eachother one going from north western Ukraine into Belarus and another south of it going from west/central Ukraine into east Slovakia and Romania . The former having much higher rates of R1a and the the latter being dominated by I2a

I don't deny that. There is just one thing - language is not the same as genetics. Slavic languages were born about 2000 years ago and there is not much dispute among linguists that it originated in the Balkan region, genetically most likely in the Z280>CTS1211>CTS3402(>Y33) subgroup.

Maybe this image gives you the picture. The 'West-Slavs' (in pink) as an M458 group are genetically distinct from the Balto-Slav group (in green), but Balts are not Slavs, and they are closer to the Slavs than the 'West-Slavs', which means that the latter cannot be Slavs in the strict sense of the word. The age of the slavic language family is about 2000-2500 years, while the separation between the M458 and the whole Z280 branch is about 4700 years take or leave 5-10%. The most convenient explanation is that the 'West-Slavic' M458 branch was slavisized and had not spoken a slavic language initially.

Haha, that's just a matter of time! As Austrians have unlearned to make babies and slavic naturalized citizens even that out, there is no doubt that Austria sooner or later will become a balkan province. Sorry to tell you, but the Slovak citizens in Eastern Austria aren't doing the baby job either, so no South-Slovakia in future!

Your argument makes zero sense. Poland is dominated by M458 and they genetically cluster extremely close to Belarusians, south Russians, and Ukrainians. Slovaks cluster closest to south eastern poles and western ukrainians. Slovaks aren't even completely m458 but share more R1a in common with eastern slavs and Slovenians. Also it's no surprise that Baltic people share common ancestry with slavs as the supposed ancestral group from both linguistic groups was Balto-Slavic and they have had a lot of contact historically from Eastern slavs. If western slavs weren't slavs originally then why does R1a-m458 drop drastically among non Slavic nations?

From seeing your comment you must be Yugoslavian living in Austria, also steirmark having 40 percent R1a is not from recent Slavic immigrants the nations ancestry is heavily Slavic. Keep dreaming about Slavic languages starting in the Balkans.

Your comments are very emotionally charged, and pivot around Balkano-Slavic nationalism. I find you more romantic than realist. I don't think we can have any rational discussion with you.
