Wild chimpanzees consume the equivalent of 2 cocktails a day in the form of boozy fruit, research finds

In the forests of Uganda and Côte d'Ivoire, chimps crowd into fig and plum trees, feasting on fruit that's sweet, soft and just a little boozy. A new study shows those daily snacks quietly add up to the equivalent of nearly two alcoholic beverages for humans.

A team of scientists at University of California Berkeley and other institutions tested the fruit chimps actually snack on: figs in Uganda's canopy and the plum-like fruits on the forest floor in Côte d'Ivoire. Collecting the data wasn't easy — with little electricity beyond solar panels and constant humidity threatening the instruments, researchers spent three seasons hauling equipment and calibrating test kits to measure alcohol in many different tropical fruits.

In the end, they found that on average, the fruit's alcohol cont
