Caucasus Hunter-Gatherer
Caucasus hunter-gatherer (CHG), also called Satsurblia cluster, is an anatomically modern human genetic lineage, first identified in a 2015 study, based on the population genetics of several modern Western Eurasian (European, Caucasian and Near Eastern) populations. It represents an ancestry maximised in some Upper Paleolithic and Mesolithic hunter-gatherer groups in the Caucasus. These groups are also very closely related to Mesolithic hunter-gatherers and Neolithic farmers and pastoralists in the Iranian Plateau ( Iranian hunter-gatherer cluster), who are sometimes included within the CHG group. Ancestry that is closely related to CHG-Iranian hunter gatherers and farmers is also known from further east, including from the Bactria–Margiana Archaeological Complex and the Harappan/Indus Valley Civilisation. Caucasus hunter-gatherers and Eastern hunter-gatherers are ancestral in roughly equal proportions to the Western Steppe Herders (WSH), who were widely spread across Eur ...

Caucasus
The Caucasus () or Caucasia (), is a region spanning Eastern Europe and Western Asia. It is situated between the Black Sea and the Caspian Sea, comprising parts of Southern Russia, Georgia, Armenia, and Azerbaijan. The Caucasus Mountains, including the Greater Caucasus range, have conventionally been considered as a natural barrier between Europe and Asia, bisecting the Eurasian landmass. Mount Elbrus, Europe's highest mountain, is situated in the Western Caucasus area of Russia. On the southern side, the Lesser Caucasus includes the Javakheti Plateau and the Armenian highlands. The Caucasus is divided into the North Caucasus and South Caucasus, although the Western Caucasus also exists as a distinct geographic space within the North Caucasus. The Greater Caucasus mountain range in the north is mostly shared by Russia and Georgia as well as the northernmost parts of Azerbaijan. The Lesser Caucasus mountain range in the south is mostly located on the territory of sout ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ancient East Eurasians
The term Ancient East Eurasian, alternatively also known as East Eurasian or Eastern Eurasian, is used in population genomics to describe the genetic ancestry and phylogenetic relationship of diverse populations primarily living in the Asia-Pacific region, belonging to the "Eastern Eurasian clade" of human genetic diversity, and which can be associated with the Initial Upper Paleolithic (IUP) wave, following the Out of Africa migration at least 60,000 years ago. Early dispersals Ancient East Eurasians, modern humans of the Initial Upper Paleolithic (IUP) wave, are suggested to have diverged from Ancient West Eurasians around 48,000 years ago from a population hub likely on the Persian plateau, and expanded across Eurasia through a star-like expansion pattern at least 45,000 years ago. Ancient East Eurasians started to diversify among themselves as early as 45,000 years ago. This diversification may possibly be related to the development of two major IUP-affiliated types of ...

Ancient North Eurasian
In archaeogenetics, the term Ancient North Eurasian (ANE) refers to an ancestral component that represents the lineage of the people of the Mal'ta–Buret' culture () and populations closely related to them, such as the Upper Paleolithic individuals from Afontova Gora in Siberia. Genetic studies also revealed that the ANE are closely related to the remains of the preceding Yana culture (), which were dubbed as Ancient North Siberians (ANS), and which either are directly ancestral to the ANE, or both being closely related sister lineages. The ANE/ANS lineages both derive their ancestry from an admixture event between 'Ancient West Eurasians' (best represented by Upper Paleolithic Europeans such as Kostenki-14, c. 38,000 BP) and 'Ancient East Eurasians' (best represented by the Tianyuan man, c. 39,000 BP) during the Upper Paleolithic period. Around 20,000 to 25,000 years ago, a branch of Ancient North Eurasian people mixed with Ancient East Asians, which led to the emerge ...

Basal Eurasian
Basal Eurasian is a proposed lineage of anatomically modern humans with reduced, or zero, Neanderthal admixture (ancestry) compared to other ancient non-Africans. Basal Eurasians represent a sister lineage to other Eurasians and may have originated from the Southern Middle East, specifically the Arabian Peninsula, or North Africa, and are said to have contributed ancestry to various West Eurasian, South Asian, and Central Asian as well as African groups. This Basal Eurasian component is also proposed to explain the lower archaic admixture among modern West Eurasians compared with East Eurasians, although alternative explanations without need of such Basal admixture exist as well. Basal Eurasian ancestry had likely admixed into West Eurasian groups present in West Asia as early as 26,000 years ago, prior to the Last Glacial Maximum, with this ancestry being subsequently spread by later migrations, such as those of the Anatolian Neolithic Farmers into Europe during the Holocene.

Ganj Dareh
Ganj Dareh ( Persian: تپه گنج دره; "Treasure Valley" in Persian, or "Treasure Valley Hill" if tepe/tappeh (hill) is appended to the name) is a Neolithic settlement in western Iran. It is located in the Harsin County in east of Kermanshah Province, in the central Zagros Mountains. Research history First discovered in 1965, it was excavated by Canadian archaeologist Philip Smith during the 1960s and 1970s, for four field seasons. In 2017 or 2018, the site was revisited by an Iranian-Danish team of archaeologists under direction of Hojjat Darabi and Tobias Richter. The oldest settlement remains on the site date back to c. 8200 BC, and have yielded the earliest evidence for goat domestication in the world.What's Bred in the Bone '' |
Anatolian Hunter-gatherers
Anatolian hunter-gatherer (AHG) is a distinct anatomically modern human archaeogenetic lineage, first identified in a 2019 study based on the remains of a single Epipaleolithic individual found in central Anatolia, radiocarbon dated to around 13,500 BCE. A population related to this individual was the main source of the ancestry of later Anatolian Neolithic Farmers (also known as Early European Farmers), who along with Western Hunter Gatherers (WHG), Eastern Hunter Gatherers (EHG) and Western Steppe Herders (WSH) are one of the currently known ancestral genetic contributors to present-day Europeans. Introduction The existence of this ancient population has been inferred through the genetic analysis of the remains of a man from the site of Pınarbaşı (37 ° 29'N, 33 ° 02'E), in central Anatolia, which has been dated at 13,642-13,073 cal BCE. This population is genetically differentiated from the rest of the known Pleistocene populations. It has been discovered that popu ...

Last Glacial Maximum
The Last Glacial Maximum (LGM), also referred to as the Last Glacial Coldest Period, was the most recent time during the Last Glacial Period where ice sheets were at their greatest extent between 26,000 and 20,000 years ago. Ice sheets covered much of Northern North America, Northern Europe, and Asia and profoundly affected Earth's climate by causing a major expansion of deserts, along with a large drop in sea levels. Based on changes in position of ice sheet margins dated via cosmogenic nuclide, terrestrial cosmogenic nuclides and radiocarbon dating, growth of ice sheets in the southern hemisphere commenced 33,000 years ago and maximum coverage has been estimated to have occurred sometime between 26,500 years ago and 20,000 years ago. After this, deglaciation caused an abrupt rise in sea level. Decline of the West Antarctica ice sheet occurred between 14,000 and 15,000 years ago, consistent with evidence for another abrupt rise in the sea level about 14,500 years ago. Glacier fl ...
