Tianyuan Man
Tianyuan man ( zh, t=田園洞人, s=田园洞人, p=Tiányuándòng Rén) are the remains of one of the earliest modern humans to inhabit East Asia. In 2007, researchers found 34 bone fragments belonging to a single individual at the Tianyuan Cave near Beijing, China. Radiocarbon dating shows the bones to be between 42,000 and 39,000 years old, which may be slightly younger than the only other finds of bones of a similar age at the Niah Caves in Sarawak on the South-east Asian island of Borneo. Isotope analysis suggests that a substantial part of the diet of these individuals came from freshwater fish. Tianyuan man is considered an early modern homo sapiens. He lacks several mandibular features common among Western or Southern Eurasian late archaic humans, showing its divergence. Based on the rate of dental occlusal attrition, it is estimated he died in his 40s or 50s. DNA tests published in 2013 revealed that Tianyuan man is related "to many present-day Asians and Native Ame ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anatomically Modern Humans
Early modern human (EMH) or anatomically modern human (AMH) are terms used to distinguish ''Homo sapiens'' (the only extant Hominina species) that are anatomically consistent with the range of phenotypes seen in contemporary humans from extinct archaic human species. This distinction is useful especially for times and regions where anatomically modern and archaic humans co-existed, for example, in Paleolithic Europe. Among the oldest known remains of ''Homo sapiens'' are those found at the Omo-Kibish I archaeological site in south-western Ethiopia, dating to about 233,000 to 196,000 years ago, the Florisbad site in South Africa, dating to about 259,000 years ago, and the Jebel Irhoud site in Morocco, dated about 315,000 years ago. Extinct species of the genus ''Homo'' include ''Homo erectus'' (extant from roughly 2 to 0.1 million years ago) and a number of other species (by some authors considered subspecies of either ''H. sapiens'' or ''H. erectus''). The divergence of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haplogroup
A haplotype is a group of alleles in an organism that are inherited together from a single parent, and a haplogroup (haploid from the el, ἁπλοῦς, ''haploûs'', "onefold, simple" and en, group) is a group of similar haplotypes that share a common ancestor with a single-nucleotide polymorphism mutation. More specifically, a haplogroup is a combination of alleles at different chromosomal regions that are closely linked and that tend to be inherited together. As a haplogroup consists of similar haplotypes, it is usually possible to predict a haplogroup from haplotypes. Haplogroups pertain to a single line of descent. As such, membership of a haplogroup, by any individual, relies on a relatively small proportion of the genetic material possessed by that individual. Each haplogroup originates from, and remains part of, a preceding single haplogroup (or paragroup). As such, any related group of haplogroups may be precisely modelled as a nested hierarchy, in which each set (hap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hoabinhian
Hoabinhian is a lithic techno-complex of archaeological sites associated with assemblages in Southeast Asia from late Pleistocene to Holocene, dated to c.10,000–2000 BCE. It is attributed to hunter-gatherer societies of the region and their technological variability over time is poorly understood. In 2016 a rockshelter was identified in Yunnan (China), where artifacts belonging to the Hoabinhian technocomplex were recognized. These artifacts date from 41,500 BCE. Bacsonian is often regarded as a variation of the Hoabinhian industry characterized by a higher frequency of edge-grounded cobble artifacts compared to earlier Hoabinhian artifacts, dated to c. 8000–4000 BCE. Definition The term Hòa Bình culture ( vi, Văn hóa Hòa Bình, in French ''culture de Hoà Bình'') was first used by French archaeologists working in Northern Vietnam to describe Holocene period archaeological assemblages excavated from rock shelters. The related English adjective Hoabinhian (Frenc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indigenous Peoples Of Siberia
Siberia, including the Russian Far East, is a vast region spanning the northern part of the Asian continent, and forming the Asiatic portion of Russia. As a result of the Russian conquest of Siberia (17th to 19th centuries) and of the subsequent population movements during the Soviet era (1917-1991), the modern-day demographics of Siberia is dominated by ethnic Russians ( Siberiaks) and other Slavs. However, there remains a slowly increasing number of indigenous groups, between them, accounting for about 10% of the total Siberian population (about 4,500,000), some of which are closely genetically related to indigenous peoples of the Americas. History In Kamchatka, the Itelmens' uprisings against Russian rule in 1706, 1731, and 1741, were crushed. During the first uprising the Itelmen were armed with only stone weapons, but in later uprisings they used gunpowder weapons. The Russian Cossacks faced tougher resistance from the Koryaks, who revolted with bows and guns from 1745 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
East Asian People
East Asian people (East Asians) are the people from East Asia, which consists of China, Taiwan, Japan, Mongolia, North Korea, and South Korea. The total population of all countries within this region is estimated to be 1.677 billion and 21% of the world's population in 2020. However, large East Asian diasporas, such as the Chinese, Japanese, Korean, and Mongolian diasporas, as well as diasporas of other East Asian ethnic groups, mean that the 1.677 billion does not necessarily represent an accurate figure for the numbers of East Asian people worldwide. The major ethnic groups that form the core of East Asia are the Chinese, Koreans, and Japanese. Other ethnic groups of East Asia include the Ainu, Bai, Manchus, Mongols and other Mongolic peoples, Nivkh, Qiang, Ryukyuans, Tibetans, and Yakuts. Culture The major East Asian language families are the Sinitic, Japonic, and Koreanic families. Other language families include the Tibeto-Burman, Ainu languages, Mongolic, Tungusic, ...

Mainland Southeast Asia
Mainland Southeast Asia, also known as the Indochinese Peninsula or Indochina, is the continental portion of Southeast Asia. It lies east of the Indian subcontinent and south of Mainland China and is bordered by the Indian Ocean to the west and the Pacific Ocean to the east. It includes the countries of Cambodia, Laos, Myanmar, Thailand and Vietnam, with peninsular Malaysia sometimes also being included. The term Indochina (originally Indo-China) was coined in the early nineteenth century, emphasizing the historical cultural influence of Indian and Chinese civilizations on the area. The term was later adopted as the name of the colony of French Indochina (today's Cambodia, Laos, and Vietnam). Today, the term, Mainland Southeast Asia, in contrast to Maritime Southeast Asia, is more commonly referenced. Terminology The origins of the name Indo-China are usually attributed jointly to the Danish-French geographer Conrad Malte-Brun, who referred to the area as in 1804, and the ...

Genetic History Of East Asians
This article explains the genetic makeup and population history of East Asian peoples and closely related populations (i.e. Southeast Asians, Siberians, Polynesians, and Native Americans, as well as Oceanians, and, partly, Central Asians and South Asians), which are collectively referred to as "East-Eurasians" in population genomics. Overview Population genomic studies have studied the origin and formation of modern East Asians. Ancestors of East Asians split from other human populations between 50,000 and 70,000 years ago. Possible routes into East Asia by the ancestors of East Asian-related populations include a northern route model from Central Asia, and a southern route model from Southeast Asia. A third route into Northern Siberia was used by a distinct population, represented by the Ancient North Eurasians, which however did not contribute ancestry to modern East Asians, but were deeply related to European hunter-gatherers. These Ancient North Eurasians however rec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indigenous Peoples Of The Americas
The Indigenous peoples of the Americas are the inhabitants of the Americas before the arrival of the European settlers in the 15th century, and the ethnic groups who now identify themselves with those peoples. Many Indigenous peoples of the Americas were traditionally hunter-gatherers and many, especially in the Amazon basin, still are, but many groups practiced aquaculture and agriculture. While some societies depended heavily on agriculture, others practiced a mix of farming, hunting, and gathering. In some regions, the Indigenous peoples created monumental architecture, large-scale organized cities, city-states, chiefdoms, states, kingdoms, republics, confederacies, and empires. Some had varying degrees of knowledge of engineering, architecture, mathematics, astronomy, writing, physics, medicine, planting and irrigation, geology, mining, metallurgy, sculpture, and gold smithing. Many parts of the Americas are still populated by Indigenous peoples; some countries have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. 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. The same newspaper report claimed that furthe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paiter
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. Language The Paiter speak the Suruí-Paíter language, which belongs to the Tupi-Guarani language family. Portions of the Bible were translated into Suruí-Paíter in 1991. Origins A 2015 genetic study reached a surprising conclusion about the origins of the Surui people. Unlike other Native American peoples, the Surui, Karitiana, and Xavante have an ancestry partially related to indigenous populations of the Andaman Islands, New Guinea, and Australia. Scientists speculate that the relationship derives from an earlier people, called "Population Y", in East Asia from whence both groups diverged 15,000 to 30,000 years ago, the future Australasians migrating south and the remote ancestors of the Surui northward, finding their way to the New World and to the inte ...
