In every society, humans make personal sacrifices for others with no expectation that it will be reciprocated. For example, we donate to charity, or care for the sick and disabled. This trait is extremely rare in the natural world, unless there is a family relationship or later reciprocation. The origin of human altruism has puzzled evolutionary biologists for many years...
Although Bowles admits that he has found no evidence for any gene for human altruism, he says that if such a genetic disposition were to exist, group conflict would have played an important role in its development. Monogamy would also level the playing field within the group, he showed in his statistical analysis. “Monogamy limits the ability of the stronger or more aggressive males to monopolise copulation,” says Bowles. “Humans are very unusual in this way.”
