Drunken Monkey Hypothesis

Craving a beer? Feeling bad about it because you think you might be addicted to alcohol? Don't feel bad because all humans are addicted to alcohol...here's why. According to the 'Drunken Monkey Hypothesis', proposed by Dr. Robert Dudley of the University of California- Berkeley, human beings are actually attracted to ethanol (the type of alcohol we drink) because of their huge dependence on fruit throughout our evolutionary journey. Fruit, contains ethanol, and our body craves it as if we were still foraging for food. Along with this hypothesis is our desire for sugars and fats. Why you ask? For the same reasons, however, it is a two-fold answer. Firstly, sugars and fats are very high in calories, fats to be exact are worth twice as many calories as proteins. While proteins are better for us nowadays, if one of our ancestors was able to get double the energy to survive thousands of years ago, that was the better option (obviously). Also, fats and sugars were a whole lot more rare than they are today, so that coupled with the fact that we could gain more energy from these 'horrible' items, over time, ingrained a desire in our genes to crave sugar, fats, and alcohol. So whenever you feel bad about drinking, blame your ancestors of thousands of years ago.
