A leading specialist on hunter-gatherers exposes Steven Pinker’s poorly-researched claims that humans have always been war-like. Richard Lee also summarises decades of research on hunter-gatherers showing how they emphasise food-sharing, gender equality and cooperative childcare. Lee concludes that it was this sort of less aggressive and more cooperative social environment in our evolutionary past that permitted the long childhoods required for human brain growth.
