The evolution of parent-offspring conflict over mate choice

摘要: Abstract In human societies, parents often have a strong influence on the mate choice of their offspring. Moreover, empirical studies show that conflict over between and offspring is widespread across cultures. Here we provide first theoretical investigation into this conflict, showing it may result from an underlying evolutionary parental resource distribution. We present series simulations in which gradually expand standard model sexual selection by stepwise addition elements involvement. our model, females obtain resources enhancing fecundity both chosen parents. Potential mates differ ability to signal ability. Both can develop preference for signal, with preferences influencing realized female. Parents differentially allocate among daughters depending resource-provisioning abilities sons-in-law. When returns investment are diminishing, find invest most whose few resources. Subsequently, evolve exploit allocation rule through choice, not parents' best interests. This results offspring, manifested as on-going divergence preferences. predict should be pronounced when fathers, opposed mothers, control allocation.
