In which modern human populations do we find the highest evidence for denisovan DNA?

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.

Do modern humans have denisovan genes?

Denisovan-derived ancestry is largely absent from modern populations in Africa and Western Eurasia. The highest rates, by far, of Denisovan admixture have been found in Oceanian and some Southeast Asian populations, with an estimated 4–6\% of the genome of modern Melanesians being derived from Denisovans.

Who has the most denisovan DNA?

Genetic evidence now shows that a Philippine Negrito ethnic group has inherited the most Denisovan ancestry of all. Indigenous people known as the Ayta Magbukon get around 5 percent of their DNA from Denisovans, a new study finds.

What is denisovan Upsc?

Detailed Solution. The correct answer is option 2, i.e an early human species. Denisovans are an extinct species of hominid. The jawbone discovered in the Tibetan Plateau and dated to more than 160,000 years ago, is the first Denisovan fossil found outside the Siberian cave.

What percentage of human 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.

What percentage of DNA do humans share with Neanderthals?

Humans, Neanderthals share up to 98.5 percent DNA, new study reveals.

How did Denisovans help humans survive?

DNA from Mysterious ‘Denisovans’ Helped Modern Humans Survive. The existence of this archaic human group came to light in 2010 when DNA from a piece of a finger bone and two molars that were excavated at Denisova Cave in the Altai Mountains of southern Siberia was studied.

How common is Denisovan DNA in Southeast Asia?

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.

Why are Melanesians the only modern humans with Denisovan ancestry?

“It’s unclear why Melanesians are the only modern human population now that has an appreciable percentage of Denisovan ancestry,” he told Live Science. The researchers also discovered that Neanderthal and Denisovan DNA was not scattered evenly in the modern human genome.

Are Neanderthal and Denisovan DNA distributed evenly in the modern human genome?

The researchers also discovered that Neanderthal and Denisovan DNA was not scattered evenly in the modern human genome. Rather, it was concentrated more heavily in some regions than others, they said.
