This is Scientific American’s 60-Second Science, I’m Cynthia Graber. This will just take a minute.
There are plenty of tales of animals finding some alcohol and getting tipsy. But those stories usually involve manmade beer or wine. There’s been no evidence of animals seeking out naturally fermented 1 fruit in the wild—until now. Researchers stumbled upon the first example of animals looking for a drink in the Malaysian rainforest. The scientists noticed a yeasty smell wafting 2 from a local palm. They saw a frothy substance, like the head on a mug of beer. It turns out the palm’s nectar has as much alcohol as some beer does. Then scientists followed two tiny mammals – the pentailed treeshrew slow loris. The critters dip into the nectar several times nightly. They regularly guzzle 3 the equivalent of about nine drinks a night—though they don’t display what we’d consider drunken behavior. And they act as the plant’s pollinator. The research appeared in the Proceedings 4 of the National Academy of Sciences. The pentailed treeshrew is a living version of an ancient mammal, a kind of relic 5 of the mammals from which both shrews and primates 6 – and eventually humans – branched off. So this discovery could lend some weight to the hypothesis that our love of the hard stuff has a deep evolutionary 7 history. I’ll toast to that.
Thanks for the minute, for Scientific American’s 60-Second Science, I’m Cynthia Graber.
