Survival of individuals, survival of family units, survival of packs,

The one circumstance where you look out for the "other" is when it shares
some or all of your genes. Kin selection (as opposed to group selection) is
everywhere. As one of the English population geneticist quipped "I'd lay down
my life for my brother or 8 cousins".
