I'm back, but not fully, so I thought that I would share an interesting video on monkeys and their drinking habits. Notice how alike they are to humans, especially the percentages of binge drinkers, moderate drinkers, and teetotalers.
I also wanted to share part of an essay by Sam Harris, wherein he speaks about animal behavior:
And just how widespread must “glimmerings” of morality be among other animals before [Francis] Collins—who, after all, knows a thing or two about genes—begins to wonder whether our moral sense has evolutionary precursors in the natural world? What if mice showed greater distress at the suffering of familiar mice than unfamiliar ones? (They do.) What if monkeys will starve themselves to prevent their cage-mates from receiving painful shocks? (They will.) What if chimps have a demonstrable sense of fairness when receiving food rewards? (They might.) Wouldn’t these be precisely the sorts of findings one would expect if our morality were the product of evolution?

13 Our picture of chimp notions of fairness is somewhat muddled. There is no question that they notice inequity, but they do not seem to care if they profit from it.
