> Geodakyan suggested that sex dimorphism gives a species the benefit of having two functional partitions, or subsystems. The male sex is considered an operative, variation subsystem, while the female sex is a conservative one. Sex differentiation allows a species to use the male partition to try out various genetic changes, including parasitic and cooperative co-existence for possible inter-species co-evolution and expansion of ecological niches. In Geodakyan's terms, species use males as an experimental partition of sex and use another partition (female) to maintain the features of the species that were proven to be beneficial.
