I’ve posted in different places about how our morality might be related to that of other primates. But of course its also quite different. Here is a great review of the book “Mothers and Others” by Sarah Blaffer Hrdy. The book argues that at some point humans made and interesting break from their primate ancestors by choosing to share the responsibilities of raising their young.
Our capacity to cooperate in groups, to empathize with others and to wonder what others are thinking and feeling — all these traits, Dr. Hrdy argues, probably arose in response to the selective pressures of being in a cooperatively breeding social group, and the need to trust and rely on others and be deemed trustworthy and reliable in turn. Babies became adorable and keen to make connections with every passing adult gaze. Mothers became willing to play pass the baby. Dr. Hrdy points out that mother chimpanzees and gorillas jealously hold on to their infants for the first six months or more of life. Other females may express real interest in the newborn, but the mother does not let go: you never know when one of those females will turn infanticidal, or be unwilling or unable to defend the young ape against an infanticidal male.
