Costs of Cooperative Breeding
The primary disadvantage of cooperative breeding is the cost of expending energy towards raising the offspring of another individual. A study conducted by Cornwallis et al. showed a strong negative correlation between the evolution of promiscuity and the evolution of cooperative breeding, suggesting that cooperative breeding is more likely to evolve in populations where females mate with fewer males. For species with multiple-mating systems, the time and energy spent raising another’s offspring would prove too costly for cooperative breeding to be selected for.

Famous quotes containing the words costs, cooperative and/or breeding:
“The real price of everything, what everything really costs to the man who wants to acquire it, is the toil and trouble of acquiring it.”
—Adam Smith (1723–1790)
“Then we grow up to be Daddy. Domesticated men with undomesticated, frontier dreams. Suddenly life—or is it the children?—is not as cooperative as it ought to be. It’s tough to be in command of anything when a baby is crying or a ten-year-old is in despair. It’s tough to feel a sense of control when you’ve got to stop six times during the half-hour ride to Grandma’s.”
—Hugh O’Neill (20th century)
“Good breeding ... differs, if at all, from high breeding only as it gracefully remembers the rights of others, rather than gracefully insists on its own rights.”
—Thomas Carlyle (1795–1881)
