George Town: Universiti Sains Malaysia's Centre for Archaeological Research Malaysia has found evidence of early human existence in the country dating to 1.83 million years ago. The evidence was obtained through the discovery of artefacts in Bukit Bunuh, Lenggong, Perak.

The centre director Associate Professor Mokhtar Saidin said the evidence found included stone-made tools such as handaxe and chopping tools.

The artefacts were found embedded in suevite rock, formed as a result of the impact of meteorite crashing down at Bukit Bunuh.

The suevite rock, reputedly the first found in Southeast Asia, was sent to the Geochronology Japan Laboratory three months ago and carbon dated using the Fission Track dating method.

Mokhtar said the results were sent back to USM two weeks ago and it showed the rock was dated to 1.83 million years ago.

He said based on current studies there was fresh evidence of human mobility coming from Asia and Southeast Asia, and not just out of Africa.

"This discovery may make the rewriting of the 'out of Africa' theory necessary," he said.

Based on world evidence, there was early human existence 'out of Africa' in Georgia (1.8 to 1.7 million years ago); Sangiran, Jawa, Indonesia (1.7 to 1.2 million years ago); as well as Longgupo and Yuanmou in China (1.8 to 1.6 million years ago).

He noted that with the new evidence, there was a possibility that the race in Jawa could have migrated from Bukit Bunuh as a result of destruction from the impact of meteorites.

The four square-km site, which was first excavated between 2001 and 2003, revealed the Paleolithic culture, which was dated at 40,000 years ago.

The meteorite crash site was also discovered, the impact of which had caused the stones in its original state at Bukit Bunuh to melt, congeal and subsequently form the suevite rock.

USM Vice-Chancellor Tan Sri Prof Dzulkifli Abdul Razak said the discovery was an important one for USM and the country as it would enable researchers to understand the origins of early humans in this region.

He said the new discovery would also change the understanding of human exploration in this region.
