“Why do males of some species attend to their offspring prolongedly, while others tend to spring off post-coitally?” asks Natalie Angier. The answer may relate to the varying social role of infants. “In 90 percent of mammalian species, promiscuity is common and paternity uncertain; females gestate the young internally and then provision them with breast milk, and males rarely have any evolutionary incentive to play Ward Cleaver.
