Ево шта кажу у уводу:
"Ancient genomes from Eurasia have revealed three ancestral populations that contributed to contemporary Europeans in varying degrees. Mesolithic individuals, sampled from Spain all the way to Hungary, belong to a relatively homogenous group, termed
western hunter-gatherers (
WHG). The expansion of
early farmers (
EF) out of the Levant during the Neolithic transition led to major changes in the European gene pool, with
almost complete replacement in the south and
increased mixing with local WHG further north. Finally, a later wave originating with the Early Bronze Age Yamnaya from the Pontic steppe, carrying partial ancestry from ancient
North Eurasians (
ANE) and ancestry from a
second,
undetermined source, arrived from the east, profoundly changing populations and leaving a cline of admixture in Eastern and Central Europe. This view, which was initially based on a handful of genomes, was recently confirmed by extensive surveys of Eurasian samples from the Holocene.
Here, we extend our view of the genetic makeup of early Europeans by both looking further back in time and sampling from the crossroads between the European and Asian continents. We sequenced a Late Upper Palaeolithic (
‘Satsurblia’ from Satsurblia cave,
13,300 years old, 1.4-fold coverage) and a Mesolithic genome (
‘Kotias’ from Kotias Klde cave,
9,700 years old, 15.4-fold) from
Western Georgia, at the very eastern boundary of Europe. We term these two individuals
Caucasus hunter-gatherers (
CHG). To extend our overview of WHG to a time depth similar to the one available for our samples from the Caucasus, we also sequenced a western European Late Upper Palaeolithic genome,
‘Bichon’ (
13,700 years old, 9.5-fold) from
Grotte du Bichon,
Switzerland. These new genomes, together with already published data, provide us with a much improved geographic and temporal coverage of genetic diversity across Europe after the Last Glacial Maximum (LGM).
We show that CHG belong to a new, distinct ancient clade that split from WHG ~45 kya and from Neolithic farmer ancestors ~25 kya.
This clade represents the previously undetermined source of ancestry to the Yamnaya, and contributed directly to modern populations from the Caucasus all the way to Central Asia."
Иначе, на еупедији се може наћи податак да овај узорак из Швајцарске припада Y-DNA хаплогрупи
I2a1a2a-L1286 (негативна на M423 и M26), што би значило да је то најстарији Y-DNA хаплотип пронађен у Европи (не рачунајући Русију). Узорци из Грузије су
