Denisovans
The Denisovans or Denisova hominins ( ) are an extinct species or subspecies of archaic human that ranged across Asia during the Lower Paleolithic, Lower and Middle Paleolithic, and lived, based on current evidence, from 285 thousand to 25 thousand years ago. Denisovans are known from few physical remains; consequently, most of what is known about them comes from DNA evidence. No formal species name has been established pending more complete fossil material. The first identification of a Denisovan individual occurred in 2010, based on mitochondrial DNA (mtDNA) extracted from a Juvenile (organism), juvenile finger bone excavated from the Siberian Denisova Cave in the Altai Mountains in 2008. Nuclear DNA indicates close affinities with Neanderthals. The cave was also periodically inhabited by Neanderthals, but it is unclear whether Neanderthals and Denisovans ever cohabited in the cave. Additional specimens from Denisova Cave were subsequently identified, as was a single specimen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Interbreeding Between Archaic And Modern Humans
Interbreeding between archaic and modern humans occurred during the Middle Paleolithic and early Upper Paleolithic. The interbreeding happened in several independent events that included Neanderthals and Denisovans, as well as several unidentified hominins. In Europe, Asia and North Africa, interbreeding between archaic humans and Early modern human, modern humans took place several times. The introgression events into modern humans are estimated to have happened about 47,000–65,000 years ago with Neanderthals and about 44,000–54,000 years ago with Denisovans. Neanderthal-derived DNA has been found in the genomes of most contemporary populations, varying noticeably by region. It accounts for 1–4% of modern genomes for people outside Sub-Saharan Africa, although estimates vary, and either none or up to 0.3% for those in Sub-Saharan Africa. Cushitic-speaking peoples, Cushitic and Semitic languages, Semitic speaking populations from the Horn of Africa (such as Ethiopians), wh ...

Human Evolution
''Homo sapiens'' is a distinct species of the hominid family of primates, which also includes all the great apes. Over their evolutionary history, humans gradually developed traits such as Human skeletal changes due to bipedalism, bipedalism, dexterity, and complex language, as well as interbreeding with other hominins (a tribe of the Homininae, African hominid subfamily), indicating that human evolution was not linear but weblike. The study of the origins of humans involves Interdisciplinary, several scientific disciplines, including Biological anthropology, physical and evolutionary anthropology, paleontology, and genetics; the field is also known by the terms anthropogeny, anthropogenesis, and anthropogony—with the latter two sometimes used to refer to the related subject of hominization. Primate evolution, Primates diverged from other mammals about (Myr, mya), in the Late Cretaceous period, with their earliest fossils appearing over 55 mya, during the Paleocene. Prima ...

Denisova Cave
Denisova Cave () is a cave in the Altai Mountains, Bashelaksky Range of the Altai Mountains in Siberia, Russia. It is widely known for having provided items of great archaeology, paleoarchaeological and paleontology, paleontological interest. In particular, the 2008 discovery of bone fragments that in 2010 have been conclusively established to have belonged to a separate early human species - the Denisova hominin - which is named after the cave. Other items including artifacts dated to around 40,000 Before Present, BP. Remains of a 32,000-year-old prehistoric species of Equus (genus), horse have also been found in the cave. The cave is located in a region thought to have been inhabited concurrently in the past by Neanderthals and by modern humans. A bone needle dated to 50,000 years ago was discovered at the archaeological site in 2016 and has been described as the most ancient needle known (though another possible needle dates to about 10,000 years earlier from South Africa f ...

Archaic Human
''Homo'' () is a genus of great ape (family Hominidae) that emerged from the genus ''Australopithecus'' and encompasses only a single extant species, ''Homo sapiens'' (modern humans), along with a number of extinct species (collectively called archaic humans) classified as either ancestral or closely related to modern humans; these include ''Homo erectus'' and ''Homo neanderthalensis''. The oldest member of the genus is ''Homo habilis'', with records of just over 2 million years ago. ''Homo'', together with the genus ''Paranthropus'', is probably most closely related to the species ''Australopithecus africanus'' within ''Australopithecus''.'''' The closest living relatives of ''Homo'' are of the genus ''Pan (genus), Pan'' (chimpanzees and bonobos), with the ancestors of ''Pan'' and ''Homo'' estimated to have diverged around 5.7–11 million years ago during the Late Miocene. ''H. erectus'' appeared about 2 million years ago and spread throughout Africa (deba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neanderthal
Neanderthals ( ; ''Homo neanderthalensis'' or sometimes ''H. sapiens neanderthalensis'') are an extinction, extinct group of archaic humans who inhabited Europe and Western and Central Asia during the Middle Pleistocene, Middle to Late Pleistocene. Neanderthal extinction occurred roughly 40,000 years ago with the immigration of modern humans (Cro-Magnons), but Neanderthals in Gibraltar may have persisted for thousands of years longer. The first recognised Neanderthal fossil, Neanderthal 1, was discovered in 1856 in the Neander Valley, Germany. At first, Neanderthal 1 was considered to be one of the racial hierarchy, lower races in accord with historical race concepts. As more fossils were discovered through the early 20th century, Neanderthals became characterised most especially by Marcellin Boule as a unique species of underdeveloped human. By the mid-20th century, human evolution was described as progressing from an apelike ancestor, through a "Neanderthal phase", ending ...

Dali (fossil)
Dali man () is the remains of a late ''Homo erectus'' or archaic ''Homo sapiens'' who lived in the Calabrian (stage), late-mid Pleistocene epoch. The remains comprise a complete fossilized skull, which was discovered by Liu Shuntang in 1978 in Dali County, Shaanxi Province, China. Dating the skull is a matter of debate. While uranium-series dating of ox teeth from the same site in 1994 obtained a date of , it is unclear whether the hominid cranium and the ox teeth date from a similar era.P. BrowDali archaic ''Homo sapiens''University of New England, Australia (2002) A new analysis performed in 2017 used a variety of methods, arriving at an age estimate of about . The fossil is considered to be the most complete skull of that time period found in China. Access to Dali Man is restricted. The cranium is currently housed in the Institute of Vertebrate Paleontology and Paleoanthropology in Beijing, China. Characteristics of the skull The Dali cranium is interesting to modern anth ...

Melanesians
Melanesians are the predominant and Indigenous peoples of Oceania, indigenous inhabitants of Melanesia, in an area stretching from New Guinea to the Fiji Islands. Most speak one of the many languages of the Austronesian languages, Austronesian language family (especially ones in the Oceanic languages, Oceanic branch) or one of the many unrelated families of Papuan languages. There are several creoles of the region, such as Tok Pisin, Hiri Motu, Pijin language, Solomon Islands Pijin, Bislama, and Papuan Malay. Origin and genetics The origin of Melanesians is generally associated with the first settlement of Australasia by a lineage dubbed 'Australasians' or 'Australo-Papuans' during the Initial Upper Paleolithic, which is "ascribed to a population movement with uniform genetic features and material culture" (Ancient East Eurasians), and sharing deep ancestry with modern East Asian people, East Asian peoples and other Asia-Pacific groups. It is estimated that people reached Austral ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baishiya Karst Cave
Baishiya Karst Cave () is a high-altitude paleoanthropological site and a Tibetan Buddhist sanctuary located on the northeastern edge of the Tibetan Plateau in Xiahe County, Gansu, China. This karst cave is the site of the discovery of the earliest hominin fossil found on the Tibetan Plateau, the Xiahe mandible. The mandible, by way of palaeoproteomic analysis, is the first confirmed discovery of a Denisovan fossil outside of Denisova Cave. This fossil discovery shows that archaic hominins were present in a high-altitude, low-oxygen environment by around 160,000 years ago. Geography Baishiya Karst Cave is located in Ganjia (), Xiahe County, Gannan Tibetan Autonomous Prefecture, Gansu, China, on the northeastern edge of the Tibetan Plateau. It lies on the southern side of Dalijiashan Mountain, at the foot of a white cliff. The cave is situated in the Ganjia Basin, at the mouth of the Jiangla River, a tributary of the Yangqu River. The cave is over in length. Within from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aboriginal Australians
Aboriginal Australians are the various indigenous peoples of the Mainland Australia, Australian mainland and many of its islands, excluding the ethnically distinct people of the Torres Strait Islands. Humans first migrated to Australia (continent), Australia 50,000 to 65,000 years ago, and over time formed as many as 500 List of Aboriginal Australian group names, language-based groups. In the past, Aboriginal people lived over large sections of the continental shelf. They were isolated on many of the smaller offshore islands and Tasmania when the land was inundated at the start of the Holocene Interglacial, inter-glacial period, about 11,700 years ago. Despite this, Aboriginal people maintained extensive networks within the continent and certain groups maintained relationships with Torres Strait Islanders and the Makassar people, Makassar people of modern-day Indonesia. Over the millennia, Aboriginal people developed complex trade networks, inter-cultural relationships, law ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
