Laurie Taylor explores the latest research into how society works. Darwinian theory has provided a powerful explanation for animal behaviour, but can it be used to explain how humans act? Evolutionary psychologists contend that it can and have brought their critique to bear on many fields including economics, law, anthropology and sociology. Laurie speaks to Lesley Newson about her theory that evolution can explain how societies become modern. Also on the programme, why western women are increasingly relaxed about attending sex clubs and 'ping pong' bars in Thailand. Erin Sanders tells Laurie about her latest research.
