Humans and some other great apes share an unusual adaptation: They can metabolize ethyl alcohol – the intoxicating ingredient in beer, wine and cocktail spirits – 40 times more efficiently than other primates.
This genetic change – called the A294V mutation by scientists – gave the last common ancestor of African apes and humans two things: the ability to consume fermented fruits, and a reason to gather in large groups in a relaxed atmosphere. That’s the conclusion of a recently published paper by researchers from the University of St Andrews and Dartmouth College.
