Researchers were able to take into account the degree of relatedness, the number of pups the mother already had, as well as the survival probability of the littler after increasing its size, and they found that females would only adopt orphaned pups if Hamilton’s Rule were satisfied (rB>C, where B is the benefit to the recipient, C is the cost to the altruist, and r is the coefficient of relatedness).
