As evolutionary scientists, we devote much of our working lives to exploring the behaviour of humans and other animals through an evolutionary lens. So it may come as a surprise that our show at this year’s Edinburgh Fringe is named Alas, Poor Darwin …?, borrowing from one of the most searing critiques of evolutionary psychology ever written. We’ve added a question mark, but still – it’s no simple tale of how our minds evolved.
Evolutionary theory is a bit like a chocolate ice cream in the hands of a two-year old: it’s going to get applied everywhere, but will anything useful be achieved in the process? The central tenets of Darwinian theory – variability, heredity and selection – are as beautiful as they are compelling. They completely revolutionised biology.
But applying these principles to the study of human behaviour has caused far more controversy. 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.
