title: Australian prehistory: new aspects of antiquity.
abstract: Human occupation of greater Australia occurred by 50,000 years ago, probably through deliberate voyaging by a small group of people. Later migrations, if any, are unlikely to have significantly changed the original genetic and cultural make-up While early Aborigines may have hunted extinct megafauna, the data do not support a rapid "Pleistocene overkill" hypothesis. Finally, aspects of Australian Aboriginal economy, especially plant utilization, and technology-the small tool tradition, ground stone hatchets and boomerangs-are of considerable antiquity and probably originated locally.
