Southeast Asians derive the ancestry of at least four different ancient populations, say scientists who analyzed the 8000-year-old skeleton extracted DNA and demystified two existing theories about the Origin of humans in the region.
Southeast Asia is one of the most genetically diverse regions in the world, but for over 100 years, scientists have disagreed about the theory of the origin of the population of the region.
One theory believed that native Hoabinhian hunter-gatherers who populated Southeast Asia A few years ago, farming practices were adopted independently, without the input of the first farmers of Southeast Asia. 39 East Asia.
Another theory, called the "two – layer model," promotes the idea that migrant rice farmers of present – day China replace the Hoabinhian hunter.
A study, published in the journal Science, shows that no theory is completely accurate. The researchers found that current populations in Southeast Asia are derived from at least four older populations.
The DNA of human skeletons from Malaysia, Thailand, the Philippines, Vietnam, Indonesia, Laos and Japan dates back to 8000 years ago.
Scientists had previously managed to sequence only 4,000-year-old samples from the region.
Samples also included Hoabinhian hunter-gatherer DNA and a Japanese Jomon – a first scientist, revealing a long suspected genetic link between the two populations.
A total of 26 ancient human genome sequences were studied by the group and compared with modern DNA samples from people living in Southeast Asia today.
Amount of effort in recovering old DNA from tropical Southeast Asia that could shed new light on this area of rich human genetics, "said Eske Willerslev, who holds positions at Cambrid University "The fact that we were able to obtain 26 human genomes and shed light on the incredible genetic wealth of groups in the region today is amazing," said Willerslev, who said led the study.
"The history of human occupation in Southeast Asia remains highly debated. Our research focused on Hoabinhian at the Iron Age and found that current populations in Southeast Asia are derived from at least four ancient populations. This is a much more complex model than we previously thought, "said Fernando Racimo, an assistant professor at the University of Copenhagen PTI MHN MHN
