An Evolutionary Basis for Ethics?

What happened? The monkeys that were still being rewarded with cucumber refused to collect any more pebbles. There is something peculiarly human about this reaction and the concept of justice it suggests. Mere conditioning, as with Skinner's pigeons, comes nowhere near explaining this.

I know atheism has no concrete relation to evolution, but there is a remarkable correlation between atheism and an undying fealty towards evolution. So, with that said, I imagine that trend will continue with whomever I speak with in the biology department.

Maybe it doesn't make sense in the short term, looking at energy in-energy out, but perhaps a sense of fairness i.e. getting your "fair share" has long term evolutionary benefits for a social animal, i.e. those who've settled for second best have had less offspring overall. In a longer study, though, they might have caved if the cucumber was the only sustenance on offer.
