Wild chimpanzees may be consuming the equivalent of two glasses of alcohol each day through their natural diet of fermented fruit, according to recent research.
The surprising finding, detailed in studies published by Science | AAAS and Discover Magazine, suggests that chimpanzees ingest ethanol through the fermentation process that occurs within fallen fruit on the forest floor.
Researchers observed that the amount of ethanol consumed varies depending on the ripeness of the fruit and the time of year, but consistently reaches levels comparable to those found in a standard alcoholic beverage. This discovery challenges previous assumptions about primate alcohol consumption and raises questions about the evolutionary basis of our own attraction to alcohol.
The study highlights how naturally occurring ethanol in chimpanzees’ diet may have played a role in their evolutionary history. Understanding this could provide insights into the complex relationship between primates and intoxicating substances. The findings underscore the importance of considering natural behaviors when studying the origins of human preferences and habits.
Although the effects of this ethanol consumption on chimpanzee health and behavior are still being investigated, researchers note that the levels observed do not appear to cause noticeable impairment. Further research is planned to explore the potential long-term effects of regular ethanol ingestion on chimpanzee populations.
