The Selfish Gene by Richard Dawkins goes a long way towards explaining self-sacrifice. His theory is that it is genes that look after themselves, not organisms. Thus, if sacrificing one individual organism saves a whole bunch of genes, that will be selected for. Early humans travelled in small groups, all of whom were related to each other. A gene that caused one or more individuals in the group to sacrifice themselves for the group (the largest males protecting the group from a predator), that gene would be continued through the other members of the group. If the whole group got wiped out, none of those genes would carry forward.
