Ancient DNA from cave sediments: a new horizon in the archaeology of Aboriginal Australia. Archaeological cave deposits at Devil's Lair and nearby sites in south-west Western Australia document 48,000 years of occupation by the first Australians. Using ancient DNA isolated from cave sediment the project will identify the diversity of plants and animals, thereby providing new insights into past environments and Aboriginal hunter-gatherer practices.
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.
