Well, if we look at humans as a species then obviously the greater part of that is prehistorical. Clearly our "nature" is not incompatible with collectivism when looking at small communities and groups.

However, I think you have a point when it comes to more complex societies with increasingly larger populations, which, as a rule, have tended to form hierarchical class systems that are antithetical to collectivist ideals.

So we could say that humans have historically been fine with communism up to a certain point. It's when they start to form nation states and larger communities that societies have generally gravitated towards hierarchy and plutocracy, for whatever reason.
