Renowned paleoanthropologist Bernard Wood explains how continuing research into fossil and other evidence of our evolutionary history produces insights but also reveals how much we have yet to learn. How good, for example, are we at telling our recent ancestors and close relatives from those of the apes? How can we know how many species preceded our own? And can we tell which of those species are our ancestors, and which are non-ancestral close relatives? Presented by Dr Andi Horvath.
Environmental legal scholar Prof. Robin Craig argues that the doctrine of sustainability in managing our natural resources fails to take into account an emerging age of ecological uncertainty. Instead, notions of sustainability and sustainable development need to make way for approaches based on resilience thinking, which attempts to factor in and adapt to coming large-scale social and ecological shifts brought about by climate change. Presented by Eric van Bemmel.
Bioethicist Peter Sandøe discusses our complicated relationship with animals and associated moral dilemmas, including how our love for companion animals can actually cause harm and the difference between society’s treatment of pets and production animals. Presented by Peter Clarke.
Plant population specialist Prof Roger Cousens talks about how the spread of undesirable plants, or "weeds", has dramatically redefined the world’s natural landscapes and coastlines, and what this means for us economically, aesthetically and environmentally. Presented by Dr Andi Horvath.
Conservation ecologist Assoc. Prof. Brendan Wintle considers the difficult questions and dilemmas that arise in decisions around species and ecosystem conservation, and whether a monetary value can or should be applied to nature. Presented by Dr Dyani Lewis.
Marine biologist, Prof Robert Warner, discusses the relationship between marine predators and their prey. He also explains why marine environments may be more robust than terrestrial ecosystems in the face of human impacts. Presented by Dr Dyani Lewis.
In a wide ranging discussion on ageing, Professor Dame Linda Partridge delves into the research findings on longevity in humans and animals, and ponders evolutionary perspectives on the ageing process. Presented by Dr Shane Huntington.
Evolutionary biologist Dr Devi Stuart-Fox explains how bird species in which plumage color form varies from member to member evolve into new species at a faster rate than species of a uniform plumage color form -- confirming a half century-old evolutionary theory. Presented by Dr Shane Huntington.
