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.
