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]
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, 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.
By way of protein analysis, researchers concluded that the Xiahe specimen belonged to a population that was closely related to the Denisovan specimens from Denisova Cave. [9] This is the first time that an ancient hominin was successfully identified using only protein analysis. [10] It is the most complete known Denisovan fossil. [10]
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 ...
Neanderthals and Denisovans are more closely related to each other than they are to modern humans, meaning the Neanderthal/Denisovan split occurred after their split with modern humans. [ 14 ] [ 47 ] [ 93 ] [ 113 ] Assuming a mutation rate of 1 × 10 −9 or 0.5 × 10 −9 per base pair (bp) per year, the Neanderthal/Denisovan split occurred ...
Katerina Douka (born c. 1980) is an archaeological scientist whose work focuses on the spatio-temporal pattern of human dispersals and extinctions across Eurasia, including Neanderthals, Denisovans and modern Homo sapiens.
Entomologist Dr. Gerard Talavera came across 10 painted lady butterflies on a beach about a decade ago in French Guiana. With torn wings peppered with holes, the insects appeared worn out.
