The oldest stone tools found in Southeast Asia potentially rewrites our understanding of human origins

13 Comments

A hand axe found in Perak, peninsular Malaysia has been dated to 1.83 million years, making it the oldest stone tool discovered in the part of the world. More significantly, this find also raises some serious questions about the out-of-Africa hypothesis of human origin. The oldest modern man in Southeast Asia is dated to around 50-60,000 years ago, and the oldest hominid fossil, Java Man (homo erectus) is placed between 1 and 1.7 million years ago. It’s been all over the news this weekend, and I’m sorry for not posting this up sooner especially seeing how I am at the said Centre for Archaeological Research in Universiti Sains Malaysia (I’ve been away to celebrate the Chinese Lunar New Year).

The soil in which the tools were discovered in were dated by fission-track dating, but they do have a wide margin of error of about 600,000 years. At this stage, the results haven’t been independently verified.
