Ochre archaeomicrobiology: a new tool for understanding Aboriginal exchange. This project aims to identify the origins and movements of Australian archaeological ochre through the development of a novel tool combining genomic and chemical analysis. The geographic distribution of Australian ochre is closely linked to Aboriginal creation stories, while its physical distribution by people is evidence of cultural cooperation.

This project aims to identify the origins and movements of Australian archaeological ochre through the development of a novel tool combining genomic and chemical analysis. The geographic distribution of Australian ochre is closely linked to Aboriginal creation stories, while its physical distribution by people is evidence of cultural cooperation. Using this new archaeomicrobiological technique, the project aims to answer significant questions about past human behaviour, in terms of trade, cultural interactions, territoriality and colonisation. The method also has the potential to benefit traditional owners by contributing to repatriation projects. The collaborative detailed recording, sampling and analysis of ochre sources on traditional lands will also assist Aboriginal communities to manage this important aspect of their cultural heritage.Read moreRead less
Early African woodworking and tool use at the transition to modern humans. Our archaeological excavations and preliminary dating of Amanzi Springs (South Africa) to between 515,000 and 163,000 years ago shows that the site covers a critical time period that led to the origins of our species, Homo sapiens. Amanzi documents, in never before seen resolution, the technological leaps that our ancestors made during this transition. At ~400,000 years ago this includes the oldest evidence for woodworkin ....Early African woodworking and tool use at the transition to modern humans. Our archaeological excavations and preliminary dating of Amanzi Springs (South Africa) to between 515,000 and 163,000 years ago shows that the site covers a critical time period that led to the origins of our species, Homo sapiens. Amanzi documents, in never before seen resolution, the technological leaps that our ancestors made during this transition. At ~400,000 years ago this includes the oldest evidence for woodworking and tool use and >163,000 years ago the oldest heat treatment of rock to make stone tools. The organic preservation at the site means that we can reconstruct changing environment, linked to sea level changes and spring activity, for this period in the evolution of our ancestors at a level of detail not previously possibleRead moreRead less
A powerful new genetic view of the recent evolutionary history of humans and their diseases. Bacteria on teeth cause dental disease, but have also recently been associated with broader health issues, including diabetes, stroke and heart issues. In this project ancient DNA will be used to reveal changes in these bacteria as humans moved from a hunter-gatherer to farming lifestyle, providing valuable background information for modern dental/medical practice.
A 140,000 year insight into the imprint of climate and humans on Australia. Before the arrival of Europeans, two events shaped Australia's current landscapes and biota more than any others: climate change during the glacial cycle and the arrival of humans on the continent. However, the full scale of these events is not well understood. High resolution analyses of two continuous 140 000 year old sediment deposits will be used in this project to fill this void and answer fundamental questions abou ....A 140,000 year insight into the imprint of climate and humans on Australia.
