From the moment of birth, human infants require an inordinate amount of care and, unlike our nearest living relatives, remain dependent on a variety of caretakers during an unusually long maturation period followed by extraordinary adult longevity. How did such a distinctive pattern of development evolve and what other human features are linked to it? Barry Hewlett (Washington State Univ, Vancouver) begins with a discussion on Sharing Childcare and Knowledge in Infancy, followed by Kristen Hawkes (Univ of Utah) on Grandmothers and the Extended Family, and Hillard Kaplan (Univ of New Mexico) on Human Fathers.
