Can you visit Denisova Cave?
The place is not easily reachable, it is very far from all big cities – the nearest is Novosibirsk, 400 km away – and documentation is lacking. However, they are slowly building some facilities, and the place can be visited for free, while the archeologists can be seen excavating in real time.
Does Denisovan DNA still exist?
The percentage of Denisovan DNA is highest in the Melanesian population (4 to 6 percent), lower in other Southeast Asian and Pacific Islander populations, and very low or undetectable elsewhere in the world.
What did Archaeologists find in the Denisova Cave?
About a decade ago, DNA extracted from a tiny finger bone unearthed at the site revealed the existence of an entire new branch of the Homo evolutionary tree, which researchers dubbed the Denisovan after the name of this Russian site.
Has a Denisovan skull been found?
To date, the only clearly identified Denisovan fossils are a pinkie bone, teeth, and a bit of skull bone from Denisova Cave. But the enormous, “weird” molar from the new find fits with the molars from Denisova, says Bence Viola, a paleoanthropologist at the University of Toronto who analyzed them with Hublin.
Who discovered denisovan?
In 2008, Russian scientists Michael Shunkov (paleontologist) and Anatoly Derevianko (archaeologist) discovered a terminal finger phalanx from a young girl, dubbed “X-woman,” in the Denisova Cave in the Altai Mountains of Russia (see Figures 34.1 and 34.2).
Which of the following were found at Denisova Cave in southern Siberia?
Humans—including Neanderthals and Denisovans—are known to have occupied Denisova Cave for at least 300,000 years. Among the eight human fossils unearthed there are the pinkie, three bones from Neanderthals, and even one from a child with one Neanderthal and one Denisovan parent.
What did Denisovan look like?
But although ascertaining what the Denisovans looked like is incredibly difficult, there are some clues. The few fossils we have suggest that the Denisovans had big teeth, a large stocky jaw and possibly a flattened and broad neurocranium (braincase).
What did the Denisovans look like?
This analysis suggested that Denisovans, much like Neanderthals, had a long, broad, and projecting face; larger nose; sloping forehead; protruding jaw; elongated and flattened skull; and wide chest and hips. However, the Denisovan tooth row was longer than that of Neanderthals and anatomically modern humans.
When did Denisovans go extinct?
It’s unclear when Denisovans went extinct, but some studies suggest it may have been as late as 20,000 years ago.
What did ancient Denisovans look like?
Where have Denisovan remains been found?
Siberia, Russia
One was discovered in China, and five were found in the Denisova Cave in Siberia, Russia. It’s from that Siberian cave that scientists recovered and later analyzed nearly 3,800 bone fragments which would reveal three Denisovan fossils dated to be 200,000 years old.
Did the Denisovans come from Africa?
The ancestors of Neanderthals and Denisovans split from our shared ancestor about 600,000 years ago, quite likely in Africa. They expanded into Eurasia, where the Neanderthals moved west while the Denisovans moved east. By roughly 40,000 years ago, both populations became extinct.
How many Denisovan bones have been found?
In total, the researchers discovered 56 Denisovan anatomical features that may have differed from humans or Neanderthals, 34 of them in the skull.
What did Denisovan man look like?

How much of our DNA is Denisovan?
“It’s true that individual humans have a very low per cent of their genome that might have been from Neanderthal or Denisovan ancestry – non-Africans can have between 1.5 to 2.1 per cent of their genome that originated from Neanderthal ancestry,” says Schaefer.
Are there any Denisovans today?
Denisovans were a group of archaic humans first identified from a single pinkie bone in a Siberian cave. They coexisted with modern humans and other archaic human species, such as Neanderthals, for hundreds of thousands of years, until they went extinct an estimated 30,000 to 50,000 years ago.
