Human Evolutionary Studies

The transition from Oldowan to Acheulean technologies are hypothesised to be concomitant with advances in cognition and behaviour. However, the nature of these shifts, and their cultural and evolutionary implications are poorly defined and understood. While extensive literature exists on these technologies, significant differences in research methods and traditions make comparative and comprehensive analyses problematic.

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.

Our knowledge of human evolution is limited by several factors. One is tightly linked to the nature of the fossil record, as bones of our extinct human relatives and other primate species rarely appear in archaeological and paleontological sites, and when they do, they very commonly appear in an isolated fashion and/or are highly fragmented. These factors more severely affect studies of limb bones, which have been vaguely analysed or even ignored in certain cases.

Fordwich has been revealed to be the oldest directly-dated Acheulean occurrence in the United Kingdom, with artefacts dating from 560,000 to 620,000 years ago (MIS 15). This makes it the second oldest Acheulean site in north-west Europe, and the oldest to display a known handaxe assemblage numbering into the hundreds. The site is technologically diverse, with flakes, cores, handaxes, scrapers and retouched implements identified. This makes Fordwich a unique archaeological occurrence in northern Europe.

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.
