Abstract

What do you do when the environment varies frequently and unpredictably? You can hedge your bets! In nature, there are two ways of being a bet-hedger. There are generalists that are not particularly good, but not particularly bad either in the various possible environments. Alternatively, individuals can hedge their bets by creating a phenotypically diverse set of offspring such that at least some of them will be fit no matter how the environment changes. We have created a simple computational model of adaptation in a variable environment and surprisingly, without any direct incentive, we observed the evolution of both strategies.
