Karitiana

The Karitiana or Caritiana are an indigenous people of Brazil, whose reservation is located in the western Amazon. They count 320 members, and the leader of their tribal association is Renato Caritiana. They subsist by farming, fishing and hunting, and have almost no contact with the outside world. Their tongue, the Karitiâna language, is an Arikém language of Brazil.

Studies of population genetics often use the Karitiana as a reference population for Native Americans, using DNA samples made available through the Human Genome Diversity Project and other sources. [2] [3] DNA from Karitiana individuals was collected in 1987 by Francis Black and in 2007 it was reported that this sampling was undertaken unbeknownst to FUNAI, the Brazilian agency that regulates contact between the indigenous tribes and the outside world, and that the samples were being distributed for a fee with no benefit to the Karitiana, giving rise to claims of biopiracy. [4] The same newspaper report claimed that further samples were taken in 1996 by Dr. Hilton Pereira da Silva, a doctor on a documentary film crew, on the promise of medicinal supplies that were never fulfilled. [5] A response from Dr. Silva suggests that the news story was faulty and the medicinal samples he took were never used for any commercial purpose. [6]

Origins

A 2015 genetic study reached a surprising conclusion about the origins of the Karitiana people. While the Karitiana people are closely related to other Native Americans, they share closer relations to Southeast Asians & Polynesians compared with other Native Americans which are closest to Siberians and Northeast Asians. [7] [8]

A study by Iosif Lazaridis (2014) found Karitiana to carry Mal'ta MA1 (41%) admixture while the other geneflow in Karitiana appears to have an Eastern Eurasian origin. [9] A study by Kanazawa-Kiriyama et al. (2017) detected gene flow from Karitiana to Mal'ta MA1 (21%) which is in the reverse direction of what was reported in previous studies such as Raghavan et al. 2014 who used a much larger sequence data. The authors speculate that the inverse flow could be due to Ancient Beringian migration in a westward migration into Eurasia. [10]

Yamnaya culture Archaeological culture from the Pontic steppe

The Yamnaya culture also known as the Yamnaya Horizon, Yamna culture, Pit Grave culture or Ochre Grave culture, was a late Copper Age to early Bronze Age archaeological culture of the region between the Southern Bug, Dniester, and Ural rivers, dating to 3300–2600 BC. Its name derives from its characteristic burial tradition: Я́мная is a Russian adjective that means 'related to pits (yama)', and these people used to bury their dead in tumuli (kurgans) containing simple pit chambers. The people of the Yamnaya culture were likely the result of a genetic admixture between the descendants of Eastern European Hunter-Gatherers and people related to hunter-gatherers from the Caucasus, an ancestral component which is often named "Steppe ancestry", with additional admixture of up to 18% from Early European Farmers. Their material culture was very similar to the Afanasevo culture, and the populations of both cultures are genetically indistinguishable. They lived primarily as nomads, with a chiefdom system and wheeled carts and wagons that allowed them to manage large herds.

Haplogroup I is a human mitochondrial DNA (mtDNA) haplogroup. It is believed to have originated about 21,000 years ago, during the Last Glacial Maximum (LGM) period in West Asia. The haplogroup is unusual in that it is now widely distributed geographically, but is common in only a few small areas of East Africa, West Asia and Europe. It is especially common among the El Molo and Rendille peoples of Kenya, various regions of Iran, the Lemko people of Slovakia, Poland and Ukraine, the island of Krk in Croatia, the department of Finistère in France and some parts of Scotland and Ireland.

Haplogroup R1, or R-M173, is a Y-chromosome DNA haplogroup. A primary subclade of Haplogroup R (R-M207), it is defined by the SNP M173. The other primary subclade of Haplogroup R is Haplogroup R2 (R-M479).

Genetic history of Europe Aspect of history

The most significant recent dispersal of modern humans from Africa gave rise to an undifferentiated "non-African" lineage by some 70-50 ka. By about 50-40 ka a basal West Eurasian lineage had emerged, as had a separate East Asian lineage. Both basal East and West Eurasians acquired Neanderthal admixture in Europe and Asia.

Peștera cu Oase is a system of 12 karstic galleries and chambers located near the city Anina, in the Caraș-Severin county, southwestern Romania, where some of the oldest European early modern human (EEMH) remains, between 37,000 and 42,000 years old, have been found.

The Paiter, also known as Suruí, Suruí do Jiparaná, and Suruí de Rondônia, are an indigenous people of Brazil, who live in ten villages near the Mato Grosso–Rondônia border. They are farmers, who cultivate coffee.

Genetic history of the Middle East

The genetic history of the Middle East is the subject of research within the fields of human population genetics, archaeogenetics and Middle Eastern studies. Researchers use Y-DNA, mtDNA, and other autosomal DNAs to identify haplogroups and haplotypes in ancient populations of Egypt, Persia, Mesopotamia, Anatolia, Arabia, the Levant, and other areas.

The genetic history of the British Isles is the subject of research within the larger field of human population genetics. It has developed in parallel with DNA testing technologies capable of identifying genetic similarities and differences between both modern and ancient populations. The conclusions of population genetics regarding the British Isles in turn draw upon and contribute to the larger field of understanding the history of the human occupation of the area, complementing work in linguistics, archaeology, history and genealogy.

Haplogroup R1a, or haplogroup R-M420, is a human Y-chromosome DNA haplogroup which is distributed in a large region in Eurasia, extending from Scandinavia and Central Europe to southern Siberia and South Asia.

African admixture in Europe

African admixture in Europe refers to the presence of admixture events attributable to dispersal of populations inhabiting Africa in the genetic history of Europe. Certain Y-DNA and mtDNA lineages are thought to have spread from Northeastern Africa to the Near East during the later Pleistocene, and from there to Europe with the Neolithic Revolution. More recent, direct African admixture – primarily Berber admixture from North Africa – is associated with the Carthaginian period as well as Muslim conquests of the Early Middle Ages, and is primarily concentrated in the Iberian peninsula, averaging from ~11% in the west and south to ~3% in the northeast, dropping to close to 0% in the Basque region. North African admixture has also been detected in the island of Sicily.

Malta–Buret culture Paleolithic archeological culture

The Mal'ta–Buret' culture is an archaeological culture of c. 24,000 to 15,000 BP / 22'050 to 13'050 BC in the Upper Paleolithic on the upper Angara River in the area west of Lake Baikal in the Irkutsk Oblast, Siberia, Russian Federation. The type sites are named for the villages of Mal'ta (Мальта́), Usolsky District and Buret' (Буре́ть), Bokhansky District.

Western Steppe Herders Archaeogenetic name for an ancestral genetic component

In archaeogenetics, the term Western Steppe Herders (WSH), or Western Steppe Pastoralists, is the name given to a distinct ancestral component first identified in individuals from the Eneolithic steppe around the turn of the 5th millennium BCE, subsequently detected in several genetically similar or directly related ancient populations including the Khvalynsk, Sredny Stog, and Yamnaya cultures, and found in substantial levels in contemporary European and South Asian populations. This ancestry is often referred to as Yamnaya Ancestry, Yamnaya-Related Ancestry, Steppe Ancestry or Steppe-Related Ancestry.
