Southeast Asia is a region that has several stories as well as theories related to the origin of the population. Countries such as Singapore, Myanmar, Vietnam, Thailand, the Philippines and others are considered the most genetically diverse regions of the world. But, after more than 100 years of controversy, scientists have now found traces of the human origins of 8,000-year-old skeleton DNA.
According to previous theories, while a section of experts thought that 44,000 years ago a few years ago, the indigenous hunter-gatherers of Hòabìnhian lived in the Southeast Asian region. East and enriched their locality by providing agriculture. Some theorists referred to the "two-layer model". However, the new discoveries, which were published in the journal Science, showed that the first two theories were inaccurate. Academics from around the world conducted the new research and they discovered that the current population of Southeast Asia originated from at least four older populations.
To find the ultimate answer to the mystery, scientists collected DNA samples. have been found in Malaysia, Thailand, the Philippines, Vietnam, Indonesia, Laos and Japan. The study also revealed that up to now, scientists have been able to sequence 4,000-year-old samples, but this time the samples taken came from 8,000 skeletons.
L & D Study revealed that samples taken included the DNA of hunter Hòabìnhian -gatherers as well as a Jomon, who belonged to a period between 14,000 – 300 BC. Scientists compared a total of 26 old human DNA with samples from the current population of Southeast Asia.
The international study was conducted by Professor Eske Willerslev, who holds the position at St John's College, University of Cambridge and University of Copenhagen. While explaining the results, he said that even though the study required a lot of effort, "we managed to get 26 human genomes and shed light on the incredible genetic wealth of the clusters. the region today. "
the lead authors of the study, Hugh McColl, who is also a PhD student at the Center for GeoGenetics at the Museum of Natural History of Denmark. University of Copenhagen, said that out of 26 human genomes, "25 from Southeast Asia, a Japanese" We showed that no interpretation corresponded to the complexity of the history of the Southeast Asia. "
" The Hunan-hunter-gatherers and farmers of East Asia contributed to the current diversity of South-East Asia. The findings help solve one of the long-standing controversies in prehistory of Southeast Asia, "he added.
The other senior author and assistant professor at the GeoGenetic Center of Dr. Fernando Racimo also stated that the occupation of the people, who lived in Southeast Asia, was a dubious topic. In addition, he said that "Our research focused on the Hòabìnhian at the Iron Age and discovered that current populations of Southeast Asia are derived from at least four ancient populations. , a much more complex model than we thought before. "
Through the development of technology and science, this discovery of research is certainly helpful in rewriting the history of the South Asian population, as scientists have learned the radiation dose that has killed thousands of civilians during the bombings of Hiroshima and Nagasaki in 1945. analyze the bone of the victims.
