“Which is why, if you compare our babies to those of apes, the apes’ babies are far more developed. You’d have to gestate a human baby for eighteen to twenty-one months to achieve similar development at birth. Compared to other species, our offspring are born almost completely helpless. They need their parents, so those parents bond with them. As a result, we form villages, social structures to protect our young. Family units. Evolution met that biological challenge—that obstetric dilemma—with a cultural, societal solution. One that makes us human.”
