The evolutionary explanations for human behaviour that grab the headlines can often be neat; really neat – like tightly-plotted narratives in which everything works out perfectly in the end, usually with a guy getting a girl, where everything happens for a reason.Real life rarely makes for such a neat story. We’ve all seen enough action movies to notice that the more satisfying the ending, the more plot holes you have to ignore as you walk out of the cinema. Neatness makes a good story, but it’s not enough for good science.
