The Evolution of Humans

Evolutionary biologist J.S. Haldain famously said I would gladly jump in a river to save two of my brothers or eight of my cousins So this is known as kin selection rather than individual selection. What distinguishes our species is that humans get together and cooperate Irrespective of kinship so that led people to think about group selection. If you and your fellow tribe members are the type who cooperate Then as a group you all increase your chances of survival. This kind of thinking allows Organisms to operate as Superorganisms.
