Oh and btw. your "mother of all Slavs" theory is crap as the scientists found out.
Searching of the "proto-Slavs homeland" they found genetic evidence that TWO distinct groups of Slavs exist....that makes for at least two mothers! ;)

Although referred to as 'Slavs' and speaking a Slavic language, modern South Slavic peoples' genetic roots actually stem from a wide variety of genetic backgrounds, attesting the complexity of the ethno-genetic processes in Eastern Europe.
The second group comprises most southern Slavic populations: Bulgarians, most of the Croats, Bosniaks, Macedonians and Serbs, who have a significantly lower frequency of R1a (~15%).
According to the authors, this phenomenon is explained by "...contribution to the Y chromosomes of peoples who settled in the Balkan region before the Slavic expansion to the genetic heritage of Southern Slavs..."[28]
So, Poland is definitely NOT the cradle of the Serbs (or the other way around), you belong definitely not to the same mythic Über-Slavs who according to you once ruled all of Europe and they are in no way responsible for your idiocies....and their IQ is definitely higher than yours, they are much more successfull too....there is not much connection to you at all!
Better start searching for your own mom, she isn't polish...
Finally the testing results suggest a common ancestry of all Balkan populations, with a lack of correlation between genetic differentiation and language or ethnicity, stressing that no major migration barriers have existed in the making of the complex Balkan human puzzle.[39][40] The genetic homogeneity among Balkan populations suggests either a most recent common ancestor of all southeastern European populations or strong gene flow between them, which eliminated any initial differences.
Taking into account that the region has had a relatively high population density since the Neolithic period and that this region represents a crossroads of routes connecting the cultural centers of Middle East with different European areas.[41]
In short, a Serb is more Middle Eastern and Albanian than connected to a Pole! ROFL
