Exciting new paper just published in Nature indicates evidence for humans in Sumatra as early as 63,000 years ago from a reinvestigation of remains at Lida Ajer cave. The findings and location of the site imply that humans were adept at rainforest exploitation from a very early period, and that perhaps the migration of early humans from Southeast Asia to Australia may not necessarily hugged the coastline as theorised.
