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.
Geneticist Dr Andrew Weeks and animal behaviourist Dr Michael Magrath discuss diverse ways of dealing with threatened animal populations. Australia's Mountain Pygmy Possum is one such endangered species for which a combination of genetic and breeding solutions are being tried. With science host Dr Shane Huntington.
Science historian Professor Naomi Oreskes explains why limits in the predictive capacity of climate models present a challenge to those favoring adaptation above emissions mitigation as a strategy in dealing with climate change. With host Eric van Bemmel.
Historian, literary critic and author Professor Deirdre Coleman connects naturalist Henry Smeathman's years in West Africa to the social norms and intellectual life 18th century England. With host Jennifer Cook.
