Slippery descent: Untangling the complexity of our evolutionary history

Prof Bernard Wood

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.

The end of sustainability: Realism and resilience in managing our natural resources

Prof Robin Craig

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.
