摘要
Organisms often respond to environmental change phenotypically, through learning strategies that enhance fitness in variable and changing conditions. But which strategies should we expect in 族群 exposed to those conditions? We address this question by developing a 數學 model that specifies the consequences of different mixtures of individual and 社會 learning strategies on the frequencies of different 文化 variants in temporally and spatially changing environments. Assuming that alternative 文化 variants are differently well-adapted to diverse environmental conditions, we are able to evaluate which mixture of learning strategies maximises the mean fitness of the 族群. We find that, even in rapidly changing environments, a high proportion of the 族群 will always engage in 社會 learning. In those environme
