The principle described in the statement is known as differential parental investment, which refers to the unequal investment of time, energy, and resources between the genders in the care and upbringing of offspring. This principle helps to explain the evolution of sexual selection, which refers to the selection of traits that increase an individual's chances of mating success. In species where one gender invests more heavily in parental care, that gender is typically more choosy in selecting a mate, as they have more at stake in the success of the pairing.
