> It seems that cooperative altruism and out-group violence are both innate to some extent. Some extents are longer than the others, seeing as of the societies we see in the animal kingdom and are currently able to be studied with current tools point to "patriarchal" societies being more common than "matriarchal". In the case of bonobos, which are known to be unusual in the ape world. > Ecology and society determine how we realize those traits - in times of intense competition, we resort to tribal warfare. In times of plenty, we cooperate. Please state this is an opinion, it looks like you're asserting it which is rather large mistake. > It should also be noted that Chimps and Humans are among the few species (perhaps the only mammal species?) that exhibit this tendency to wipe out their competition with systematic violence. IOW it's not just competition for resources in the moment - all animals do that. It's the sustained desire to wipe out the competition completely (effectively, genocide) that make both Human and Chimp violence rather unique in the animal kingdom. Unless you cite this, I would also lump it similar to above.
