摘要
We develop an analytically tractable model of female preference for fit mates. Our 族群-遺傳 model allows to trace the dynamics at both the individual and the 族群 level. The preference for fit mates links ecological 適應 and mating success is individually advantageous and causes polymorphic sub族群s. This polymorphism is a strong and stable clustering in genotype and phenotype space. The alleles coding for the mating preference spread rapidly through the 族群, thereby increasing the selection pressure between different habitats. The resulting polymorphism exceeds the expected selection-migration equilibrium by several orders of magnitude. The 演化 of preference for fit mates can, thus, act as the trigger for parapatric speciation because it initiates prezygotic isolation and divergence.
