The Denisovans or Denisova hominins ( / dəˈniːsəvə / də-NEE-sə-və) are an extinct species or subspecies of archaic human that ranged across Asia during the Lower and Middle Paleolithic, and lived, based on current evidence, from 285 to 25 thousand years ago. [1] Denisovans are known from few physical remains; consequently, most of what ...
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 or possibly all contemporary populations, varying noticeably by region.
Archaic humans. Archaic humans[a] is a broad category denoting all species of the genus Homo that are not Homo sapiens (which are known as modern humans). Among the earliest modern human remains are those from Jebel Irhoud in Morocco (about 315 ka), Florisbad in South Africa (259 ka), [1][2][3][4][5][6], Omo-Kibish I (Omo I) in southern ...
Denisova Cave. Denisova Cave (Russian: Денисова пещера, romanized:Denísova peshchéra, lit. 'the cave of Denis'; Altay: Аю-Таш, romanized:Ayu Tash, lit. 'Bear Rock' [ 2 ]) is a cave in the Bashelaksky Range of the Altai Mountains, Siberian Federal District, Russia. The cave has provided items of great paleoarchaeological and ...
Early human migrations. Putative migration waves out of Africa and back migrations into the continent, as well as the locations of major ancient human remains and archeological sites (López et al., 2015). Early human migrations are the earliest migrations and expansions of archaic and modern humans across continents.
Multiregional origin of modern humans. The multiregional hypothesis, multiregional evolution (MRE), or polycentric hypothesis, is a scientific model that provides an alternative explanation to the more widely accepted "Out of Africa" model of monogenesis for the pattern of human evolution. Multiregional evolution holds that the human species ...
The Toba eruption (sometimes called the Toba supereruption or the Youngest Toba eruption) was a supervolcanic eruption that occurred about 74,000 years ago during the Late Pleistocene [2] at the site of present-day Lake Toba in Sumatra, Indonesia. It was the last in a series of at least four caldera -forming eruptions at this location, with the ...
Neanderthal genetics. Genetic studies on Neanderthal ancient DNA became possible in the late 1990s. [1] The Neanderthal genome project, established in 2006, presented the first fully sequenced Neanderthal genome in 2013. Since 2005, evidence for substantial admixture of Neanderthal DNA in modern populations is accumulating. [2][3][4]
