Would you rather get 100 euros for certain, or have a fifty-fifty chance of receiving either 200 euros or nothing? Most choose the first, as humans tend to be "risk-averse", preferring a guaranteed pay-off over the possibility of a greater reward. It is thought that the human preference for "playing it safe" has evolved through natural selection: when you live precariously, like our remote ancestors, losing all your food reserves might be catastrophic, while adding to them might not make much difference to your chances of survival.

Here, in one of the first studies on risk preferences in animals other than primates, scientists show that wolves are consistently more prone to take risks when gambling for food than dogs. When faced with the choice between an insipid food pellet and a fifty-fifty chance of either tasty meat or an inedible stone, wolves nearly always choose the risky option, whereas dogs are more cautious.
