Caucasus hunter-gatherer (CHG), also called Satsurblia cluster, [1] [2] is an anatomically modern human genetic lineage, first identified in a 2015 study, [3] [1] based on the population genetics of several modern Western Eurasian (European, Caucasian and Near Eastern) populations.
A genetic study in 2015 by Jones et al. identified a previously unidentified lineage, which was dubbed Caucasian Hunter-Gatherer (CHG). [3] The study detected a split between CHG and so-called "Western European Hunter-Gatherer" (WHG) lineages, about 45,000 years ago, the presumed time of the original peopling of Europe.
They analysed genomes from two hunter-gatherers from Georgia which were 13,300 and 9,700 years old, and found that these Caucasus hunter-gatherers were probably the source of the farmer-like DNA in the Yamnaya.
Historically, ethnographic studies on hunter-gatherer subsistence strategies have long placed emphasis on sexual division of labour and most especially the hunting of big game by men. This culminated in the 1966 book Man the Hunter, which focuses almost entirely on the importance of male contributions of food to the group. As this was published ...
The West Eurasian ancestry, which is closely related to Mesolithic hunter-gatherers and Neolithic farmers who lived on the Iranian Plateau (who are also closely related to Caucasus hunter-gatherers), forms the major source of the South Asian genetic makeup, and combined with varying degrees of AASI ancestry, formed the Indus Periphery Cline ...
Most Yamnaya genomes studied to date exhibit admixed EHG (Eastern Hunter Gatherer) & CHG (Caucasus Hunter Gatherer) ancestry with each in robust proportions, often with CHG ancestry higher than 50%... the Maikop culture (3600-3000 BC) is regarded in many scenarios as the likely source of the CHG that mixed with steppe EHG mating networks to ...
Researchers excavated five unmarked graves at the cemetery in 1999 in an effort to find Samuel Washington’s resting place. They recovered small bones and teeth from three burials, but DNA ...
[3] [14] Furthermore, more recent studies have found that the Y-DNA of Early European Farmers is typically haplogroup G2a. [15] According to a 2015 study, [5] a hunter-gatherer from Samara (dated 5640-5555 cal BCE) belonging to haplogroup R1b1(*) was ancestral for both haplogroups R-M269 and R-M478. According to the authors, the occurrence of ...
