Detailed explanation-1: -Parental investment theory, a term coined by Robert Trivers in 1972, predicts that the sex that invests more in its offspring will be more selective when choosing a mate, and the less-investing sex will have intra-sexual competition for access to mates.
Detailed explanation-2: -According to Parental Investment Theory, the sex that has higher parental investment will be more selective when choosing a mate, while the sex with lower investment will compete intrasexually for mating opportunities (Trivers, Reference Trivers and Campbell1972).
Detailed explanation-3: -Differential parental investment predicts that men are more likely than women to be physically aggressive in order to win at intrasexual competition and emerge dominant over intrasexual competitors (Campbell 1999).
Detailed explanation-4: -Females, because they produce eggs, make a larger parental investment prior to mating. Males can replenish their gamete supply and return to the mating pool sooner than females because they produce small, cheap sperm rather than large, costly eggs.
Detailed explanation-5: -Any investment made by a parent in an individual offspring that increases the offsprings chance of survival (hence chance of reproductive success) at the cost of the parents ability to invest in other offspring.
