Australopithecus sediba, discovered in 2008 in southern Africa, is the most significant paleo-archeological find in recent years. These fossilized specimens have anatomical features lying somewhere between those found in Australopithecus africanus and Homo erectus. Geochemist Dr Robyn Pickering discusses the significance of the find, and how the age of A. sediba was determined. With science host Dr Shane Huntington.
Biologists Prof Marilyn Renfree and Assoc Prof Andrew Pask talk Tassie Tiger, and explain how the humble mouse has aided genetic understanding of the extinct marsupial, the Thylacine. With host Dr Shane Huntington.
