It really isn't, a lot of human traits can't be explained by simply thinking of selection (in evolution) only happens at the individual level.

For instance, why do people get so old if they stop breeding at age 40 or so (women at least, men have a harder time getting children when they're older too) ? People can live to be 70 or more, even before modern medicine this was true. But if you look at group dynamics, an older, wiser, more experienced person might bring a significant advantage to a group. After all, in most 'primitive' cultures, old people are revered.

Of course, this is pure speculation, and not science.
