Chimpanzees are our closest living biological relative right? Did early hominids live in fission-fusion societies like modern chimps currently do? If so, division and competition is long back in the line, much before the level of reciprocal altruism which may have lead to bipedalism. Since Neanderthals began taking care of their sick and elderly, and since anatomically modern humans began doing that, they never really ceased taking care of their sick and elderly.
Admittedly, progress probably stopped for a while, and the process of moving from band, to tribe, to chiefdom, to state certainly did engender a lot to engender hostility between factions as work became more specialized and rank could be passed on from parent to child.
I posit, however, that humans are more altruistic (if reciprocally altruistic) than antagonistic. How many men does it take to build a skyscraper? How many men does it take to feed a nation? What are feelings of care for a group you don't necessarily share genes with? What is adoption?
Yeah, U.S. culture today encourages us to look out for number one, but who among us has not shared their lunch with a platonic friend even though there was only enough to get one of you actually full?
