Simulations illustrating the evolution of consistent individual differences between superficial explorers (red) and thorough explorers (blue). a, When individuals face two hawk–dove games superficial explorers evolve high levels of aggressiveness in both games, whereas thorough explorers are consistently non-aggressive. b, Confronted with both an anti-predator and a hawk–dove game a behavioural syndrome evolves: superficial explorers are bold and aggressive, whereas thorough explorers are shy and non-aggressive. These outcomes are robust across replicate simulations. c and d summarize the outcome of 20 replicate simulations for the scenarios in a and b, respectively. Each simulation is represented by two circles corresponding to the evolved trait combinations of superficial and thorough explorers. Black lines indicate the trait combinations for the simulations depicted in a and b.
