Even pesky fruit flies have a hankering for alcohol, and because the molecular signals involved in forming flies' reward and avoidance memories are much the same as those in humans, they're a good model for study.Who hankers? Every animal that eats fruits and grains. Carnivores don't hanker for alcohol.** Among humans the correlation is the same but the causation is reversed. The ethnic groups that can't tolerate alcohol tend to be carnivores, and tend to be warrior tribes. Ethnic groups that can take alcohol in moderation tend to be farming tribes. Cultural choice is determined by physical tolerance. ** The Youtube clip of a dog refusing to drink beer is remarkable. The dog is saying two things. (1) Damn! This is bad shit! I'm not gonna drink it! and (2) Hey! I'm not in charge here, but you're my friend and I want you to live. Please don't drink this shit! It will kill you!
