Abstract:
This paper presents an updated mathematical model of the evolutionary dynamics of the sexual conflict ("battle of the sexes") and its simulated reproductive outcomes. The authors highlight a whole range of life-history traits unique to our species, such as prolonged childhood, growth in parental care, etc. Based on these biosocial premises, the sexual conflict between men and women shifts into the mathematical realm of the "Prisoner's Dilemma" game. The evolutionarily stable strategy of mutual rejection of parenthood would be dominant with this PD strategy in both parents; oscillation dynamics predicted in previous models would not be expected. Despite fatal theoretical prediction of the PD evolutionary game, the newish genetic data of the EPP rates in the historical populations reveals prevalence of cooperation between both sexes, predominantly utilizing the monogamous form of sexuality. Presumably, this sexual norm could have potentially ensured reproductive success in the societies in the past.
