Denisova 4, a molar. The Denisovans or Denisova hominins (/ d ə ˈ n iː s ə v ə / 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 thousand to 25 thousand years ago. [1]
The Denisovan's two HLA-A (A*02 and A*11) and two HLA-C (C*15 and C*12:02) allotypes correspond to common alleles in modern humans, whereas one of the Denisovan's HLA-B allotype corresponds to a rare recombinant allele and the other is absent in modern humans. [48]
Denisova 11, genetic tree of ancestors. Denny (Denisova 11) is an ~90,000 year old fossil specimen belonging to a ~13-year-old Neanderthal-Denisovan hybrid girl. [1] [2] To date, she is the only first-generation hybrid hominin ever discovered. [3]
Denisovans survived and thrived on the high-altitude Tibetan plateau for more than 100,000 years, according to a new study that deepens scientific understanding of the enigmatic ancient humans ...
H. heidelbergensis in its turn spread across East Africa (H. rhodesiensis) and to Eurasia, where it gave rise to Neanderthals and Denisovans. H. heidelbergensis, Neanderthals and Denisovans expanded north beyond the 50th parallel (Eartham Pit, Boxgrove 500kya, Swanscombe Heritage Park 400kya, Denisova Cave 50 kya).
Denisovans, Neanderthals and related hybrids may have inhabited the Denisova Cave for extended periods, but perhaps not at the same time. [6] The attribution of the needle and certain other artifacts at the cave, whether to Homo sapiens or to the Denisova hominin (also sometimes known as Homo denisova ), is uncertain.
At least two other Homo lineages, H. neanderthalensis and Denisovans, survived the Toba eruption and subsequent MIS 4 ice age, as their latest presence is dated to ca. 40 kyr, [71] and ca. 55 kyr. [72] Other lineages, including H. floresiensis, [73] H. luzonensis, [74] and Penghu 1, [75] may have also survived through the eruption.
Researchers first identified Denisovans in 2010 using DNA sequences extracted from a rare tiny fragment of finger bone found in Siberia. Now, Baishiya Karst Cave, on the northeastern edge of the ...
