Animals and Alcohol: A Natural Mix

This: animals throughout the world are chowing down on berries and fruits that have turned slightly alcoholic. This phenomenon, scientists now believe, is widespread and has been happening for ages. Kimberley Hockings from the University of Exeter explains that ethanol, the type of alcohol found in fruit and grains, is everywhere. Yeast turns sugar into ethanol as fruit ages. So, fruit-eating animals probably encounter it a lot. This discovery has made researchers rethink the idea that alcohol is just a human thing. Ethanol has been around for a long time, dating back to the late Cretaceous period, about 100 million years ago. Picture Tyrannosaurus rex roaming around as fruit-bearing plants started to appear! Now, for animals like birds and small mammals, this can be dangerous. Even tiny amounts of ethanol can cause them to get drunk, which is not great when you're trying to avoid predators or navigate trees. Matthew Carrigan, a professor at the College of Central Florida, points out that animals aren't looking to get drunk like humans do. They want the calories, not the buzz. However, many of these animals have evolved ways to break down ethanol quickly. This lets them enjoy the sugary taste without getting tipsy. But is this just a theory, or do animals actually seek out intoxication? That's still up for debate. Scientists think that social drinking might have benefits, like helping animals bond. Researchers have taken pictures of primates, including Capuchin monkeys and chimpanzees, eating alcoholic fruit. This could offer some advantages for social animals, suggests Anna Bowland from the University of Exeter. But to know for sure, we need to understand if ethanol affects animals the same way it does humans.
