Do ants even have discrimination?

I was looking up reciprocity in evolution, where life evolves in one way or another to cooperate, to work together. You could say that this would lead to a species without discrimination. In that case, how did humanity get to where we are. We have the capacity to ponder upon the origins of cooperation and to establish rights to everyone, in that we must treat everyone justly, but we are the worst at delivering fair rights to anything. Are big brains good then?

Whereas, you look at ants. They exist in societies that match ours, and even surpass ours in organisation. They have to live with total obedience but they get the work done. They live without discrimination, unless black ants and red ants really don't get on. I'm not sure.

Tis interesting =]
