Natalie Angier in The New York Times:
In seeking bipartisan support for his economic policies, President Obama has tried every tip on the standard hospitality crib sheet: beer and football, milk and cookies, Earth, Wind and Fire. Maybe the president needs to borrow a new crib sheet — the kind with a genuine baby wrapped inside. A baby may look helpless. It can’t walk, talk, think symbolically or overhaul the nation’s banking system. Yet as social emulsifiers go, nothing can beat a happily babbling baby. A baby is born knowing how to work the crowd. A toothless smile here, a musical squeal there, and even hard-nosed cynics grow soft in the head and weak in the knees.
In the view of the primatologist Sarah Blaffer Hrdy, the extraordinary social skills of an infant are at the heart of what makes us human. Through its ability to solicit and secure the attentive care not just of its mother but of many others in its sensory purview, a baby promotes many of the behaviors and emotions that we prize in ourselves and that often distinguish us from other animals, including a willingness to share, to cooperate with strangers, to relax one’s guard, uncurl one’s lip and widen one’s pronoun circle beyond the stifling confines of me, myself and mine. As Dr. Hrdy argues in her latest book, “Mothers and Others: The Evolutionary Origins of Mutual Understanding,” which will be published by Harvard University Press in April, human babies are so outrageously dependent on their elders for such a long time that humanity would never have made it without a break from the great ape model of child-rearing. Chimpanzee and gorilla mothers are capable of rearing their offspring pretty much through their own powers, but human mothers are not.
