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 ...
The results show that haplogroup D introgressed 37,000 years ago (based on the coalescence age of derived D alleles) into modern humans from an archaic human population that separated 1.1 million years ago (based on the separation time between D and non-D alleles), consistent with the period when Neanderthals and modern humans co-existed and ...
H. sapiens interbred with archaic humans both in Africa and in Eurasia, in Eurasia notably with Neanderthals and Denisovans. [46] [102] The Toba catastrophe theory, which postulates a population bottleneck for H. sapiens about 70,000 years ago, [118] was controversial from its first proposal in the 1990s and by the 2010s had very little support ...
Human taxonomy. is the classification of the human species (systematic name Homo sapiens, Latin: "wise man") within zoological taxonomy. The systematic genus, Homo, is designed to include both anatomically modern humans and extinct varieties of archaic humans. Current humans have been designated as subspecies Homo sapiens sapiens ...
ISBN. 978-0-19-882125-0. Who We Are and How We Got Here is a 2018 book on the contribution of genome -wide ancient DNA research to human population genetics by the geneticist David Reich. He describes discoveries made by his group and others, based on analysis and comparison of ancient and modern DNA from human populations around the world.
Denisovan. 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 ...
Brown et al., 2004. Flores in Indonesia, shown highlighted in red. Homo floresiensis ( / flɔːrˈɛziːˌɛn.sɪs / also known as " Flores Man " or " Hobbit " after the fictional species) is an extinct species of small archaic human that inhabited the island of Flores, Indonesia, until the arrival of modern humans about 50,000 years ago.
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 ...
