Drinking to excess traced back 10 million years to ape genes. Or 3,000 years to Shamus O’Reilly.
The boozing gene can be traced back 10million years to the common ancestor humans share with chimpanzees and gorillas, new research claims.
It is believed these ancient forebears were the first to pick up fruits fermenting on the ground after they developed a lifestyle away from the trees.
Individuals able to stomach the boozy fruit would have survived better in this new environment than those who could not, programming the ability into their descendants’ genetic codes.
