the Macedonians lead the southern balkans in both the 'european' gene (HG I) and the 'balkan' gene (mutation I1b*), and have TWICE as much of the 'balkan' gene as do the greeks.
I1b* - THE BALKAN GENE - is also the single highest part of Macedonian HG I, making up 60%.
what this means is this gene was present since over 20,000 years ago in the north balkans. the greeks, as newcomers 4,000 years ago, have low levels of the BALKAN GENE. And the 20,000-year-old BALKAN GENE is DOMINATED by BALKAN 'slav-speakers'.
semino et al. excerpt:
A different scenario has to be envisioned for subhaplogroup
I1b*, which is the most frequent clade in eastern
Europe and the Balkans. It reaches its highest incidences
in Croatia (31%) and Bosnia (40%), encompassing almost
80%–90% of I (table 1). In western Europe, its
subclade I1b2 (M26) (fig. 1F) (Semino et al. 2000; Bosch
et al. 2001; Capelli et al. 2003; Maca-Meyer et al. 2003)
is found at a very low frequency (!5%), except in Sardinia
(41%), Castile (19%) (Flores et al., in press), Bearnais
(8%), and in the Basques (6%). Although subclade
I1b2 and the paragroup I1b* (the latter present at marginal
frequencies) co-occur west of the Italian Apennines,
only I1b* is present east of the Adriatic.
I1b* Y chromosomes
rapidly dissipate west of the Balkans—they are
virtually absent among Italians, Germans, French, and
Swiss (table 1; fig. 1E)—but extend eastward at notable
frequencies among Slavic-speaking populations. This
finding suggests that, similar to I1a, I1b* also may have
expanded from a glacial refuge area. However, this area
was most likely located in eastern Europe or the Balkans.
The high STR diversity of the I1b* lineages in Bosnia
supports the view that the P37 SNP might have been
present in the Balkan area before the LGM, as previously
proposed by Semino et al. (2000). Diversity h values
based on STR haplotypes for I1a are highest near Iberia
but vary substantially in different populations (table 2).
For I1b*, conversely, the highest h values are in the Balkan
populations—among Bosnians (0.93) and Croats
(0.85)—coinciding with the area of its frequency peak,
but equally high values were also observed for Czechs
and Slovaks (0.90). The lowest h values of I1b* were
detected among Turks (0.76) and in our Moldavian sample
(0.41).
...the I1a data in Scandinavia are consistent with
a post-LGM recolonization of northwestern Europe
from Franco-Cantabria, whereas the expansion of I1b*
in the east Adriatic–North Pontic continuum probably
reflects demographic processes that began in a refuge
area located in that region.
