The color scale is not . They emerged between 100,000 and 200,000 years ago, give or take, in the early and middle . It was brought to Leipzig for genetic analysis. Denisovans are a mysterious group of our ancient relatives, unknown until a decade ago, who lived alongside Neanderthals and Homo sapiens. Speculating beyond this is a bit disingenious, IMO. The Neanderthal and Denisovan populations proceeded to breed in isolation for a sufficiently long time to establish distinctive genomes.
The 2010 discoveries of Denisovans, the 2012 findings of archaic African DNA, and the additional 2012 genetic sequencing of Denisovans are part of a longer trajectory dating to the discovery of fossil Neandertals. While the new study confirms that modern humans interbred at least three times with ancient hominins—once with Neanderthals, and twice with the Denisovans—it also raises the possibility of .

The fossils of five distinct Denisovan individuals from Denisova Cave have been identified through their ancient DNA (aDNA): Denisova 2, 3, 4, 8, and 11.An mtDNA-based phylogenetic analysis of these individuals suggests that Denisova 2 is the oldest, followed by Denisova 8, while Denisova 3 and Denisova 4 were roughly contemporaneous. The other struck . For Asian people it's as much as 80 percent, and Papua New Guineans 95 percent. The most Denisovan genes are at the top, and the most Neanderthal genes are at the bottom. Sequencing Y chromosomes from two Denisovans and three Neanderthals shows that the Y chromosomes of Denisovans split around 700 thousand years ago from a lineage shared by Neanderthals and modern human Y chromosomes, which diverged from each other around 370 thousand years ago. Decades of teasing apart Neanderthal DNA has produced an archive of ancient genes that spell out a history of love affairs between estranged branches of humanity's family tree. The hominin species is thought to have ranged from . Denisovan skulls were wider than both humans and Neanderthals, for example.
We show that the archaic lineage was very small during the 10,000 y . The original Denisovan genomes were from remains once thought to have belonged to Neanderthals.
Neanderthals and early modern humans shared our planet for several thousand years. Neanderthals, Denisovans, humans genetically closer than polar bears, brown bears. This species is the first fossil hominin identified as a new species based on its DNA alone. See more ideas about ancient humans, human evolution, hominid. c. 44000 BCE - c. 54000 BCE. Fossils and DNA traces of Denisovans are found from at least 200,000 to 50,000 years ago, and those of Neanderthals from between 200,000 and 100,000 years ago. One group stayed in Africa, evolving into us. At the time of Denisova 11′s birth, the genomes of Neanderthals and Denisovans were much more different from those of even the most distantly related humans alive today.

Denisovans, a mysterious population of archaic humans that lived at around the same time as Neanderthals, could have interbred with Homo sapiens more than previously thought. Take a look at a Denisovan tooth (molar) compared to a modern human's. It is amazingly large. Inheriting Denisovan or Neanderthal immunity genes will have helped modern humans to fight the diseases of the day, but beyond the age of . Whilst mtDNA analysis in 2016 found the specimen to be carrying mtDNA of the Neanderthal type, 13 even more interesting was the DNA analysis published in 2018, the latter finding that the individual was "a first-generation Neanderthal-Denisovan offspring", i.e., the Denisova 11 bone fragment came "from an individual who had a .
