Parental Investment Theory (Middle-Level Theory in Evolutionary Psychology) 3. argument takes the reasonable premise that anisogamy produces a male-biased operational sex ratio leading to males competing for mates. Male care is then predicted to be less likely to evolve as it consumes resources that could other- wise be used to increase competitiveness. These two arguments however are.
