Human Evolutionary and Behavioural Ecology

Our understanding of the origins of our species, Homo sapiens, has undergone a major shift. New fossils, dates and genomic studies have consolidated our African origin. Yet, they also indicate a deeper past, involving multiple events. These events stretch to nearly three quarters of a million years ago (Ma), and take the problem of modern human origins into an entirely different climatic and ecological context.

As the world's remaining hunting and gathering societies interact more actively with their settled agricultural neighbours, they face major changes in their diet, mobility and community networks. The 5-year MOBILE project is studying the impact of these changes on the health and biological diversity of traditionally hunter-gatherer communities in Indonesia, in order to better understand human experience and evolution in tropical forest environments.

How did our ancestors walk? Perhaps the greatest challenge that this question has posed in the past, is the lack of methodological applications in which no study has previously reconstructed how our ancestors moved using biomechanical modelling techniques. We need to consider not just individual bones when reconstructing movement, but to look at the full body to begin to tell the story of our ancestors’ movement. Muscles animate our body, permitting us to walk, run and even dance. We must reconstruct the muscles of the body to understand ancestral locomotion.

Human evolution is a central research area in biology and anthropology and has a history of research going back more than 150 years. For most of that time, evidence has come from digging up fossils and archaeological remains. Research in human evolution has been transformed by the impact of genomics and the development of ancient DNA methodologies, producing new insights into past demography, dispersal and admixture patterns, social behaviour, selection, disease history, and more.
