What do we learn about the human mind from evolutionary theorising? One might think that evolutionary psychology is predominantly a backward-looking science that sketches the historical processes that led to specific aspects of the way we reason. But most evolutionists think their investigations have a forward-looking dimension too: they argue that pinning down the social and ecological demands made on our ancestors can help us to characterise more accurately what our minds are like right now.
