Chimpanzees share many characteristics with us, such as the use of tools and social structures, However, a new report by researchers from the University of Exeter reveals another surprising parallel.
In Guinea-Bissau's Cantanhez National Park, the researchers have managed to film wild chimpanzees eating and sharing the naturally fermented African breadfruit containing alcohol on l0 different occasions. Cameras caught chimpanzees gathering around African breadfruit trees, happily eating the fruit and passing it around.
Later tests revealed that the fruit contained alcohol-the same thing found in beer and wine-with levels reaching up to 0.61% ABV (alcohol by volume). The footage also revealed that 90% of the shared, more valuable fruit was more fermented than the less-desired 10% that was simply ripe. This suggests that the chimpanzees may have a preference for the fruit with alcohol.
Interestingly, they seemed to enjoy sharing the experience with others in their group rather than keeping the best fruit to themselves. In several cases, there was enough fruit around for chimpanzees to each choose and eat their own, but instead they shared. The research team doesn't know exactly why the chimpanzees are doing any of this, and whether they experience any noticeable effects after eating the fermented fruit, though they probably don't end up as red-faced as some humans do.But since chimpanzees are similar in many ways to humans, it very well could be that this is as much about socializing as it is about the fermented food.
This interesting discovery not only sheds light on chimpanzee behavior but,given our close evolutionary ties, also offers valuable insights into the ancient traditions of humans, "Social eating and alcohol consumption make up two key parts of party behavior in humans," say the researchers. “But does the party behavior come from a shared origin? Our data provide the first evidence for fermented food sharing and feeding by wild chimpanzees and support the idea that the use of alcohol by humans is not recent but rather has existed throughout our evolutionary history."
