Alcohol has caused a lot of damage to society but only when it is being abused. I have always firmly believed that moderate consumption of alcohol is not only beneficial but as nature would have it. There is now evidence to support my belief.
Scientists found a genetic mutation, 10 million years old, which would allow primates to digest alcohol. This could be the first record of such ability in primates. They also suggest that primates eating fruits fallen from the trees might have consumed alcohol incidentally.
Personally, I believe that without this mutation humanity never would have become civilized and may have never evolved.
