"The intra-population structuring of Belarusians
The watershed between the Baltic Sea and the Black Sea divides Belarus roughly into north-eastern (rivers descending towards the Baltic Sea basin) and south-western (rivers descending towards the Black Sea) regions. The latter, known as Polesie, is vast lowland rich in swamps and forests, and differs markedly from the northern region of Belarus. Rural populations all over Belarus, non-uniform in physical characteristics, speak numerous dialects, as an outcome of a long-lasting sedentary agricultural lifestyle [63]–[65]. Yet the pattern of their genetic variation does not follow only isolation-by-distance differentiation caused by random genetic drift. As it was pointed above, these largely latitudinal gradients within the Belarus people, reflect likely ancient movements of Y-chr
omosomes (males) from north to south, as testified by the spread pattern of N1c(Tat)-chromosomes with their frequency peak around 50–70% in eastern Fennoscandia [26], [27], [58], and, secondly, the northward movements of the carriers of NRY haplogroup I2a(P37), that have likely originated from north-western Balkans [57], [60]. The longitudinal Y-chromosomal intra-Belarus variation is less pronounced (Table S4) likely because the present-day Belarus area lies within the very epicenter of the initial spread of the dominant R1a (among the Belarus population haplogroup), including its R1a1a7(M458) limb, around the Pleistocene-Holocene boundary [55]. Because the spread of I2a(P37) Y-chromosomes from the Balkans, as well as the expansion of N1c(Tat) in East Europe, have been dated to early Holocene [26], [60], one may conclude that the core of the Belarusian patrilineal pool, comprising about three quarters of its present-day variation, may have been formed during the post-Younger Dryas - early Holocene period."
