PENANG,
6 April 2015 - DNA research has shown that the majority of Malay ethnic
groups has deep ancestries from the region of the remaining Sundaland,
which is the present-day Southeast Asia, after it has undergone several
sea-water rises due to post-glacial floodings since 25,000-21,000 years
ago.
This
was posited by a professor from the School of Anthropology and Museum
Ethnography, University of Oxford, Stephen Oppenheimer in his talk for
the Archaeological Talk Series organised by the Centre for Global
Archaeological Research (PPAG) Universiti Sains Malaysia (USM).
“Most
of the data from research carried out on samples of DNA collected from
Malay respondents indicates that these Peninsula Malaysian Malays have
deep ancestries on the Sundaland, but they also possess a minority of
lineages trace to East Asia and South Asia.
“On
the other hand, mtDNA (mitochondrial DNA) analysis of ethnic Laos [as a
comparison] shows that majority of their lineages can be traced to the
region surrounding China and Taiwan,” said Oppenheimer.
Oppenheimer, 68, specialises in genetics and has authored several books including the best seller Out of Eden: The Peopling of the World and also The Origins of the British: A Genetic Detective Story.
He
has also produced documentaries commissioned by the Discovery Channel
arising from his books which detail his attempts to trace human origins
using genetics. He is currently in close collaboration with PPAG, USM.
Lecturer
from the School of Health Sciences, USM, Associate Professor Dr
Zafarina Zainuddin elaborated on her research collaboration with
Oppenheimer where she analyses mitochondrial DNA to study lineage age of
a specific sample population.
“We
collected cheek swabs from 500 respondents of 11 sub-ethnic Malay
samples such as Javanese, Bajau, Achehnese and Minang from Peninsula
Malaysia,” said Zafarina who is currently seconded to the Malaysian
Institute of Pharmaceuticals and Nutraceuticals (IPharm).
“The
mitochondrial DNA analysis of these respondents found that these
different sub-ethnic Malays all originated from Malays and they are only
presently differentiated due to geographical and political boundaries,”
she explained.
In 2007, the archaeological discovery by Professor Dato’ Dr Mohd Mokhtar Saidin,
Director of PPAG, of a hand axe at Bukit Bunoh, Lenggong Perak has
shown evidence of earliest human occupation in Southeast Asia.
The
mitochondrial DNA findings indicate that the modern humans arrived in
Southeast Asia around 60,000 years ago, and perhaps it could be a
massive force to drive the find of a human occupation site of ~ 60,000
years ago in Peninsular Malaysia.
