> I'm fairly certain that cooperating to raise your own offspring is still considered selfish behavior. Why? Because it leads to more descendants? In that case, the premise is a tautology.

The "individual" in evolutionary game theory is generally considered the gene, not the human. A lot of facts of life - like raising offspring at all, or death - make zero sense if you consider the actor to be a person, but make a lot of sense if you consider the actor to be a gene.

  I would agree with that but it doesn't appear to be what Kümmerli is saying: > “In principle, natural selection predicts individuals to behave selfishly,” Rolf Kümmerli, co-author of the study, told PhysOrg.com. “However, we observe cooperation in humans and other organisms, where cooperation is costly for the actor but benefits another individual. That is clearly referring to the human, no?

    I think that's the "faulty premise" that TheSpiceOfLife is referring to. He's saying that building a study to explain cooperation between humans is modeling a phenomena that's a social construct anyway, when the real question is "what genes lead to behavior that ensures the survival and propagation of those genes?" Natural selection operates on the genetic level, not on the human level, so Kümmerli made an error by trying to inject natural selection arguments into a model where the primary actors are humans.

    Raising offspring presents a huge cost to the parents, but every living organism does it because it's the only way to ensure that your genes will propagate on to the next generation after your death. Those that don't are washed out of the gene pool, and irrelevant after one lifespan. Similarly, death is obviously bad for an individual - it's the termination of your existence. However, it frees up resources for new individuals who may be better adapted to conditions of the time. Species where individuals rarely die may see the whole species die off at once as they get outcompeted by other species whose individuals are better adapted to the environment. (There's a societal analogue as well here: historically, societies that hold tight to tradition and preserve the internal firms & institutions within them end up being conquered, en masse, by more competitive societies where the individual firms within them either adapt or die.)

  I'm aware of the gene-centered view of evolution, but I think that interpretation of the sentence in question is quite a stretch. If that was the intended meaning, then I apologize.
