I suppose the trickiest part is defining what we means by discrimination. My understanding is that in-group out-group dynamics are extremely prevalent in almost all cultures and societies in human history. I haven't done extensive research on this, but it seems like most "discrimination" is an extension of those dynamics. Of course, broad cultural trends can radically alter the dynamics, but I wonder if our tendency to construct them in the first place is somewhat innate.
