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]
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.

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]
The Yamnaya culture or the Yamna culture, also known as the Pit Grave culture or Ochre Grave culture, is 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 BCE. It was discovered by Vasily Gorodtsov following his archaeological excavations near the Donets River in 1901–1903. Its name derives from its characteristic burial tradition: Я́мная is a Russian adjective that means 'related to pits ', as these people used to bury their dead in tumuli (kurgans) containing simple pit chambers.
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).
Haplogroup R, or R-M207, is a Y-chromosome DNA haplogroup. It is both numerous and widespread amongst modern populations.
The genetic history of Europe includes information around the formation, ethnogenesis, and other DNA-specific information about populations indigenous, or living in Europe.
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 42,000 and 37,000 years old, have been found.
Ectodysplasin A receptor (EDAR) is a protein that in humans is encoded by the EDAR gene. EDAR is a cell surface receptor for ectodysplasin A which plays an important role in the development of ectodermal tissues such as the skin. It is structurally related to members of the TNF receptor superfamily.
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.
The genetic history of the Middle East is the subject of research within the fields of human population genomics, archaeogenetics and Middle Eastern studies. Researchers use Y-DNA, mtDNA, and other autosomal DNAs to identify the genetic history of ancient and modern populations of Egypt, Persia, Mesopotamia, Anatolia, Arabia, the Levant, and other areas.
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 Central Asia, southern Siberia and South Asia.
The Mal'ta–Buret' culture is an archaeological culture of the Upper Paleolithic. It is located roughly northwest of Lake Baikal, about 90km to the northwest of Irkutsk, on the banks of the upper Angara River.
The genetic history of the Indigenous peoples of the Americas is divided into two distinct periods: the initial peopling of the Americas during about 20,000 to 14,000 years ago, and European contact, after about 500 years ago. The first period of the genetic history of Indigenous Americans is the determinant factor for the number of genetic lineages, zygosity mutations, and founding haplotypes present in today's Indigenous American populations.
Afontova Gora is a Late Upper Paleolithic and Mesolithic Siberian complex of archaeological sites located on the left bank of the Yenisey River near the city of Krasnoyarsk, Russia. Afontova Gora has cultural and genetic links to the people from Mal'ta–Buret'. The complex was first excavated in 1884 by Ivan Savenkov.
In archaeogenetics, the term Ancient North Eurasian (ANE) is the name given 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). The Ancient North Eurasians are deeply related to Paleolithic and Mesolithic European hunter-gatherers, but also derive a significant amount of their ancestry from a deep East Eurasian source, which they received in Siberia.
In archaeogenetics, western hunter-gatherer is a distinct ancestral component of modern Europeans, representing descent from a population of Mesolithic hunter-gatherers who scattered over western, southern and central Europe, from the British Isles in the west to the Carpathians in the east, following the retreat of the ice sheet of the Last Glacial Maximum. It is closely associated and sometimes considered synonymous with the concept of the Villabruna cluster, named after Ripari Villabruna cave in Italy, known from the terminal Pleistocene of Europe, which is largely ancestral to later WHG populations.
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 populations.
In archaeogenetics, eastern hunter-gatherer (EHG), sometimes east European hunter-gatherer or eastern European hunter-gatherer, is a distinct ancestral component that represents Mesolithic hunter-gatherers of Eastern Europe.
Basal Eurasian is a proposed lineage of anatomically modern humans with reduced, or zero, archaic hominin (Neanderthal) admixture 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 to with East Eurasians, although alternatives without the need of such Basal admixture exist as well.
In archaeogenetics, the term Scandinavian hunter-gatherer (SHG) is the name given to a distinct ancestral component that represents descent from Mesolithic hunter-gatherers of Scandinavia. Genetic studies suggest that the SHGs were a mix of western hunter-gatherers (WHGs) initially populating Scandinavia from the south during the Holocene, and eastern hunter-gatherers (EHGs), who later entered Scandinavia from the north along the Norwegian coast. During the Neolithic, they admixed further with Early European Farmers (EEFs) and Western Steppe Herders (WSHs). Genetic continuity has been detected between the SHGs and members of the Pitted Ware culture (PWC), and to a certain degree, between SHGs and modern northern Europeans. The Sámi, on the other hand, have been found to be completely unrelated to the PWC.
