The African origins of Asian and Australian lithic technologies: Exploring modern human origins and dispersals using new techniques of core analysis. This project will demonstrate that Australia is committed to understanding the origins of modern humans and solving research problems within and beyond our geographic region. The history of modern human evolution in Africa has significant implications for the origins of the first Australians, Indians and Asians and will contribute to an understandi ....The African origins of Asian and Australian lithic technologies: Exploring modern human origins and dispersals using new techniques of core analysis. This project will demonstrate that Australia is committed to understanding the origins of modern humans and solving research problems within and beyond our geographic region. The history of modern human evolution in Africa has significant implications for the origins of the first Australians, Indians and Asians and will contribute to an understanding of our shared and recent common ancestry and the emergence of human diversity. Australian archaeological innovations, especially when applied to global issues such as human evolution, will continue to showcase Australian scientific expertise and achievements. The study of problem-solving and technological innovation will help understand the sophisticated nature of early Australian peoples.Read moreRead less
Mid-Holocene coral reef bleaching and recovery in the South China Sea and its implications for the modern Great Barrier Reef. Strong evidence shows the mid-Holocene was 1-2 ºC warmer than the present, implying a greater probability for coral bleaching. We have collected well-preserved mid-Holocene reef corals from the northern South China Sea, which contain growth hiatuses reflecting bleaching and mortality. We propose to use high-resolution Sr/Ca, d18O and microstructure analysis and high-preci ....Mid-Holocene coral reef bleaching and recovery in the South China Sea and its implications for the modern Great Barrier Reef. Strong evidence shows the mid-Holocene was 1-2 ºC warmer than the present, implying a greater probability for coral bleaching. We have collected well-preserved mid-Holocene reef corals from the northern South China Sea, which contain growth hiatuses reflecting bleaching and mortality. We propose to use high-resolution Sr/Ca, d18O and microstructure analysis and high-precision U-series dating of coral growth bands to determine the season and sea-surface temperature when each growth hiatus occurred and to establish the timing and duration of the growth hiatus. Reconstructed mid-Holocene coral bleaching history has important implications for management of the Great Barrier Reef during predicted global warming.Read moreRead less
