Moral origins : the evolution of virtue, altruism, and shame / Christopher Boehm.

Darwin's inner voice
Living the virtuous life
Of altruism and free riders
Knowing our immediate predecessors
Resurrecting some venerable ancestors
A natural Garden of Eden
The positive side of social selection
Learning morals across the generations
Work of the Moral Majority
Pleistocene ups, downs, and crashes
Testing the selection-by-reputation hypothesis
The evolution of morals
Humanity's moral future.
