Human cognitive plasticity extends through enduringly plastic development shaped by culture

Evidence

Natural selection has made us a cultural species by altering our development in ways that (1) slowed the growth of our bodies through a shortened infancy and extended childhood but added a growth spurt in adolescence, and (2) altered neurological development in complex ways that make our brain advanced at birth yet both highly expandable and enduringly plastic. As we go along, I will consider how our fast genetic evolution, big adult brains, slow bodily development, and gradual wiring-up are made possible only as part of a larger package of features that include the sexual division of labor, intensive parental investment in children, and the long postreproductive lives we associate with menopause. These features of our species will interact in crucial ways with cultural evolution. — Joseph Henrich, The Secret of Our Success, 220
