Dating the events that define our humanity

Liang Bua

Impact Summary

Understanding who we are and where we have come from is at the heart of the human consciousness and has a bearing on how we perceive ourselves. This research uses advanced dating techniques such as luminescence, uranium series and electron spin resonance dating to establish a precise timeline for human dispersal, occupation and evolution in Asia – the source area for our ancestors and a critical region for understanding the migrations of the first Australians. The application of these techniques has been a game changer in the field of Asian human evolution and has contributed to our present understanding of human dispersals enroute to Australia.

Research associated with impact

This research has greatly influenced our understanding of human evolution and what constitutes ‘being human’ and has challenged many of our established ideas about human dispersal across the globe. The dating of these important events have constrained; the occupation and extinction of a new species of human Homo floresiesis in Indonesia, the timing of the oldest evidence of modern humans in Southeast Asia, the timing of the earliest evidence of humans-use rainforest environments and the oldest in-situ, fully recognisable rock art motif in Australia. The age of the controversial hominid, Homo floresiensis caused a paradigm shift in palaeoanthropology and generated claims for Asia, rather than Africa as the new centre of human evolution. As a results there has been a renewed interest in excavations and discovery in Asia and huge surge in public interest in science. The new chronologies for Tam Pa Ling (70-48 ka) and Lida Ajer (73-63 ka) have pushed back the arrival time of AMH into Southeast Asia by ~20 kyr. Now both of these sites are included in models of human dispersal through the region.
