The Origin of Southeast Asia (Historical Article)
Recent research results of DNA (deoxyribonucleic acid) on human origins Asia concluded that Southeast Asia is a major geographic source of the population in Asia and then spread to the north.
The ancestors of the peoples of Asia who came out of Africa about 100 thousand years ago along the southern coast to the east and the first centered in Southeast Asia around 60 thousand years ago, then spread to various regions in the north in Asia.
This latest conclusion, mentioned, denied the earlier theory that said that there are multiple pathways of migration of the ancestors of Asia, namely through the north and south line, and denied that the people of Southeast Asia (Austronesian-speaking) were from Taiwan.
This is evident also from the growing genetic diversity of the higher to the south, while the ethnic-ethnic in Asia over the north is more homogeneous, Sangkot said that is one of the initiators of the research.
This research was carried out by more than 90 scientists from a consortium of Pan-Asian SNP (single-nucleotide polymorphisms) sheltered Human Genome Organisation (HUGO), which examined 73 Asian ethnic populations in 10 countries (Indonesia, Singapore, Malaysia, Thailand, the Philippines, India, China , Korea, Japan and Taiwan) with a total of about 2,000 samples.
Conclusion of the research which took three years and has been released in the journal Science on December 10, 2009 entitled “Mapping Human Genetic Diversity in Asia” was far more accurate than previous research that uses only the mitochondrial DNA or Y chromosome, because analyzing the whole chromosome.
Specifically that the center of civilization in Asia around 60 thousand years ago it was in Indochina or the Malay peninsula, as it still requires more detailed research.
Actually there are in Sundaland (in the South China Sea-red) which has sunk to about 12,000 to 8,000 years ago.
Genetic history of the Asian population in need of a further study of the genome with more samples and markers of higher density.Current of each individual sample was analyzed 50 thousand mark.
Our next phase will include more ethnic variety, so the branches will become more detailed look.
Mapping of genetic diversity is also very important for tracking and handling of various genetic diseases such as hepatitis, thalassemia, and others.
