The strength of the archaeological record is that it provides tangible evidence of the deep history and evolution of resource management over time and across space.
An additional selective agent influencing the evolution of resource polymorphism in this system is interspecific competition for food.
While the experimentally supplied resources are identical across microcosms, the evolution of resource specialists critically depends on the genetic and ecological diversity present in the population.
One group of such fishes, the gudgeon Sarcocheilichthys (Family Cyprinidae), provides an ideal opportunity for testing the hypothesis that bottom environmental differences lead to the evolution of resource polymorphism.
