A representative of Australia's Stolen Generations' Alliance of Aborigines has told a Senate committee that some Aboriginal children were used for medical experimentation.

Scientists studying the origins of Australia's aboriginal population have found no genetic evidence of significant immigration from outside the continent for 45,000 years after humans first arrived. Their research suggests that Australian aborigines share the same common ancestor with all other human populations: so-called 'mitochondrial Eve', who is believed to have lived in Africa between 150,000 and 200,000 years ago.
