So
there are several threads, all recently active, where the focus of the conversation has turned to (often passionate) discussions about how I2a1b1a-Din, the most common Haplogroup I subclade in the Balkans, got to the Balkans. But we seem far from reaching consensus on this forum, so here's a poll to at least put our finger to the wind regarding the direction this forum is leaning.
I've included as options several different possibilities I've read:
Paleolithic continuity: I2a-Din has been in the Balkans since the Paleolithic, and present distribution outside of the Balkans is the result of migrations out of it. There is direct geographic continuity for this clade from Gravettian culture and/or the Balkans Ice Age refuge. Proponents point out the age of Haplogroup I and the frequency distribution of I2a-Din. I've read Maciamo articulate this view, but I'm not sure if he still holds it.
The Early Indo-Europeans: I2a-Din was brought to the Balkans by the Indo-European migrations. It was part of the "original" collection of Y-DNA of Indo-Europeans. Proponents point out that everywhere that Haplogroup I is dominant nowadays speaks an IE language. How yes no was fond of this theory for a while.
Sea Peoples: I2a-Din was brought to the Balkans by seafaring groups not otherwise mentioned in this poll. The migration happened before history or early in history. Proponents point to the frequency distribution and the lack of historical verification for later migrations. How yes no explored this idea, and recently Pyrub has advocated it.
The Sarmatians: I2a-Din was brought to the Balkans by the Sarmatians. Proponents of this view cite the STR dating estimate for the clade, the apparent Asian spillover of it, and the historical attestation to Sarmatians (but not Slavs) in the Balkans. Bodin has been the most vocal advocate of this theory here.
The Slavs: I2a-Din was brought to the Balkans by expanding Slavs in the 1st millennium CE. Proponents cite the age of the clade, expert STR diversity analysis by people like Nordtvedt and Verenich, and dispute that history doesn't verify the Slavic expansions. I have supported this view, as have a few other posters.
If you believe that multiple expansions resulted in the current I2a-Din distribution in the Balkans, indicate which you feel brought most or had the greatest impact. If you feel that the data is deficient, make your best educated guess.
let me explain why sea people are listed there
all we know is this map:
http://knordtvedt.home.bresnan.net/Tree and Map for Hg I.pdf
I2a-Din is estimated to spread from Poland towards Ukraine, Russia and Balkan...
Balkan was settled with movement of Serbs and Croats.... and I2a-Din being common factor for all south Slavs that distinguish them from surrounding while other haplogroups widely differ is clearly speaking that much of it came with south Slavs, probably with Serbs and Croats.... there are some historical data that list tribes with names such as Serbs and Croats among Sarmatians.....
in my opinion, I2a-Din was already in Danube basin before Roman spread to north...
Russian primary chronicle speaks of Danubian Slavs pushed out of Danube basin towards their relatives Liakhs on north by Vlakhs (Romans)....
Over a long period the Slavs settled beside the Danube, where the Hungarian and Bulgarian lands now lie. From among these Slavs, parties scattered throughout the country and were known
by appropriate names, according to the places where they settled. Thus some came and settled by
the river Morava, and were named Moravians, while others were called Czechs. Among these
same Slavs are included the White Croats, the Serbs, and the Carinthians. For when the Vlakhs
attacked the Danubian Slavs, settled among them, and did them violence, the latter came and
made their homes by the Vistula, and were then called Lyakhs. Of these same Lyakhs some were
called Polyanians, some Lutichians, some Mazovians, and still others Pomorians.

http://www.utoronto.ca/elul/English/218/PVL-selections.pdf
Lyakhs are no other than Lechs or Poles of today...
this Danubian Slavs were based on description of their location given in russian primary chronicle in fact same people as Celtic Scordisci...
Morava is Celtic river name, and it exist in Serbia where Scordisci lived and in Czech republic which is roughly area where Danubian Slavs settled... Serb related toponyms we find in west part of Czech republic
(
http://en.wikipedia.org/wiki/Srby_(Domažlice_District) http://en.wikipedia.org/wiki/Srby_(Plzeň-South_District) http://en.wikipedia.org/wiki/Srbská_Kamenice and in west part of neigbouring Bavaria as Sorviodurum
http://en.wikipedia.org/wiki/Straubing) and small nation of Sorbs (who call themselves Serbya on northwest of Chezh republic)
worth noting is that Sorviodurum was one of the town of Raetia
http://en.wikipedia.org/wiki/Raetia and that alternative name of Serbs was Rascians
Rascians (Serbian: Raci or Раци, also Rascijani or Расцијани; Hungarian: Rác, (pl.) Rácok; German: Ratzen, Raize, (pl.) Raizen; also Ratzians, Rasciani and Natio Rasciana) was a name used to designate Serbs, or sometimes, in a wider perspective, all South Slavs
http://en.wikipedia.org/wiki/Rascians
I do not say that Serbs were Raetians... I think they were partly living in Raetia (e.g. in Sorviodurum) and we know that
At first Raetia formed a distinct province, but towards the end of the 1st century AD Vindelicia was added to it; hence Tacitus (Germania, 41) could speak of Augusta Vindelicorum (Augsburg) as "a colony of the province of Raetia".
Vindelici... = white
for Serbs we know that they came to Balkan from land of Boiki where they were (same as Croats) called "white"
http://books.google.nl/books?id=3al...do imperio&hl=nl&pg=PA153#v=onepage&q&f=false
worth noting is that white is designation for west, e.g. Belarus = bela (white) + Rus = white Russians = west Russians
now why Scordisci....
because they lived in Danube basin prior to Roman conquest... note both the Danube and Morava river being in their area....
note that from area of Scordisci, a tribe named Serdi entered Thrace and was Thracanized...
in fact in my opinion Serdi and Scordisci are just Celtic and Thracian versions of same tribal name...
http://en.wikipedia.org/wiki/Serdi
I believe Scordisci were I2a-Din, and that their ancestors were Sherdana sea peoples...let me explain...
Shar mountain (Shar Dagh in turkish) on border of FYR Macedonia and break away Serbia province of Kosovo...
In Antiquity, the mountains were known as Scardus, Scodrus, or Scordus
http://en.wikipedia.org/wiki/Šar_Mountains
Their tribal name may be connected to the name of the Scordus[4] mountain (Šar mountain) which was located between the regions of Illyriaand Paionia.
http://en.wikipedia.org/wiki/Scordisci
Scordisci have tribal name preserved in Scordus mountain, which is Shar Dagh in turkish...
I argue that Scordisci were further in past known as Sherdana sea peoples and were I2a-Din
why I argue that?
Sherdana who came from north and via seas (Black sea according to my interpretation of what is written about order of conquest of sea peoples - for more details see
http://www.eupedia.com/forum/showthread.php?26076-sea-peoples) settled in their conquest the area that is matching exactly the areas where Kurds live now.... and Kurds carry I2a-Din that by all means must have originated in Europe
Kurdi is name derived from Sherdana, same as Scord on Balkan, which with Celtic ending gave Scordisci and with Thracian ending gave Serdi...
I2a-Din is not spread only along Balkan, among Kurds, and in west Slavs... in fact, it is also widely spread in Ukraine and south Russia...this can indeed perhaps be related to Sarmatians.....
if you look at Nordvedt map, from Poland I2a-Din has spread in tri directions: northeast, east and southeast...
except south and west Balkan which was settled by I2a-Din only with early Slavs, this is Danube basin and area on north and east shores of Black sea.... and according to my projections this is where Sherdana started conquest.... from Danube basin and north shores of Black sea....
note that cultures and languages of tribes change at much faster pace than genetics.... but tribal names are often following genetics...
