New Insights into the Colonisation of Australia Through the Analysis of the Mitochondrial Genome

SESSION: Doctoral Showcase - Early Research Showcase

EVENT TYPE: Doctoral Showcase

TIME: 3:30PM - 5:00PM

SESSION CHAIR: Wojtek James Goscinski

Presenter(s):Nano Nagle


Colonisation of Australia by the ancestors of contemporary Aboriginal peoples and their subsequent isolation is a crucial event in understanding the human migration(s) from Africa ~70,000 - 50,000 years ago. However, our knowledge of genetic structure in contemporary Australian Aboriginal peoples is extremely limited and our understanding of the route taken by the migrants and their genetic composition is poorly understood. As part of the Genographic Project, we have investigated mitochondrial (mt) DNA sequence variation in ~ 300 unrelated samples of Aboriginal Australians from previously unsampled geographic locations. This is by far the largest and most geographically widespread DNA sample of indigenous Australians. Using Next Generation Sequencing to acquire whole mitochondrial genomes we are gaining new insights into the colonisation of Australia. The next step is to utilise high performance computing to infer times of arrival of the unique haplogroups in Australia, ages of the haplogroups and possible coalescence.
