They contributed DNA to Aboriginal Australians and to present-day New Guineans and an indigenous tribe in the Philippines known as Mamanwa. This study confirms Aboriginal Australians as one of the oldest living populations in the world. They are possibly the oldest outside Africa, and they may have the oldest continuous culture on the planet. [28]
Since 2005, evidence for substantial admixture of Neanderthal DNA in modern populations is accumulating. [2] [3] [4] The divergence time between the Neanderthal and modern human lineages is estimated at between 750,000 and 400,000 years ago. The recent time is suggested by Endicott et al. (2010) [5] and Rieux et al. (2014). [6]
Prior to 2021, New Guineans and Australian Aborigines were reported to have the most introgressed DNA, [22] but Australians have less than New Guineans. [66] A 2021 study discovered 30 to 40% more Denisovan ancestry in Aeta people in the Philippines than in Papuans, estimated as about 5% of the genome.
A separate DNA study, published in the journal Science, shows that modern humans held on to some key genetic traits from Neanderthals that may have given them an evolutionary advantage. One ...
DNA study leads researchers to pin humanity’s low pain thresholds on Neanderthals. The team believes that, thousands of years ago, inbreeding caused the development of key traits that were then ...
Neanderthals live on within us. Using the new and rapidly improving ability to piece together fragments of ancient DNA, scientists are finding that traits inherited from our ancient cousins are ...
[23]: 15 They were preceded by a mixture of AASI (ancient ancestral south Indian, i.e. hunter-gatherers sharing a distant root with the Andamanese, Australian Aboriginals, and East Asians); and Iranian agriculturalists who arrived in India c. 4700–3000 BCE, and "must have reached the Indus Valley by the 4th millennium BCE".
The scientists discovered that the percentage of Homo sapiens DNA in the Neanderthal genome may have been as high as 10% more than 200,000 years ago and decreased over time; on average, it was 2.5 ...
