\t\t\t\t\t<\/video><\/p>\n

A group of chimps have been filmed sharing alcoholic breadfruit, in the first example of wild primates having a booze-up on camera (well, sort of).<\/p>\n

Researchers got hold of the fruit they were eating and tested it afterwards, and found the most alcoholic one they were gorging on was 0.61% strength.<\/p>\n

It\u2019s not quite vodka, but given that chimps mainly survive on fruit, at the levels they consume it\u2019s possible they could get a buzz if they eat enough.<\/p>\n

Researchers say that sharing food around like this is not typical chimp behaviour, so it is possible they did it because they liked the booze and were engaged in social bonding. <\/p>\n

If true, it means that human behaviours passing a bottle or cigarette around a group could have deep roots in evolutionary biology.<\/p>\n

\t\t\"\"
\n\t\tDown it, lads: the chimps were seen feasting on alcoholic breadfruit<\/p>\n

The chimps were filmed enjoying themselves in the west African jungle in Guinea Bissau\u2019s Cantanhez National Park.<\/p>\n

Anna Bowland, from the University of Exeter, said: \u2018For humans, we know that drinking alcohol leads to a release of dopamine and endorphins, and resulting feelings of happiness and relaxation.<\/p>\n

\u2018We also know that sharing alcohol \u2013 including through traditions such as feasting \u2013 helps to form and strengthen social bonds.<\/p>\n

\u2018So \u2013 now we know that wild chimpanzees are eating and sharing ethanolic fruits, the question is: could they be getting similar benefits?\u2019<\/p>\n

This wasn\u2019t just a fluke. The motion-activated cameras they set up to film the chimps captured ten different occasions of the animals sharing boozy fruit.<\/p>\n

\t\t\"Wild
\n\t\tThey\u2019re just like us<\/p>\n

Nine of ten of the sharing events were \u2018passive\u2019, when a fellow chimp tolerated a peer feeding from their fruit.<\/p>\n

On one occasion, a chimp even let fruit be taken from its mouth. <\/p>\n

While it\u2019s entertaining to imagine chimps on the lash and falling asleep under trees, researchers said that they likely have better attitudes to booze than their human cousins.<\/p>\n

\t\t\t\tAlcoholic fruit and flowers\t\t\t<\/p>\n

The fruits the chimps were seen eating were relatively soft by nature\u2019s standards: the equivalent of a Coors Light lager, rather than Jack Daniels. <\/p>\n

Most of the time, naturally fermented fruits only reach 1-2% alcohol by volume (ABV).<\/p>\n

However, concentrations as high as 10.3% have been found in over-ripe palm fruit in Panama, researchers said in a previous study<\/a> last year.<\/p>\n

Alcohol was being drunk long before humans got around to brewing it.<\/p>\n

Flowering plants started producing sugary nectar containing ethanol around 100 million years ago, as well as fruits which could ferment. <\/p>\n

Dr Kimberley Hockings, who was also involved in the study published today, said: \u2018We\u2019re moving away from this anthropocentric view that ethanol is just something that humans use..<\/p>\n

\u2018It\u2019s much more abundant in the natural world than we previously thought, and most animals that eat sugary fruits are going to be exposed to some level of ethanol.\u2019<\/p>\n

They are unlikely to get drunk on the fruit, as this would not give them any evolutionary advantage, and would actually damage their survival chances (not least the fact it would be difficult to get hammered on something that is 0.6% ABV). <\/p>\n

It is possible they could share the alcoholic fruit due to its higher vitamin content, rather than its inebriating effects, though more research is needed. <\/p>\n

Scientists don\u2019t know the exact effect of alcohol on chimps\u2019 metabolism, although there have been other recent studies into animal booze consumption. <\/p>\n

A molecular adaptation that greatly increased ethanol metabolism in the common ancestor of African apes was recently discovered.\/<\/p>\n

It suggests eating fermented fruits may have ancient origins in species including humans and chimps.<\/p>\n

Dr Kimberley Hockings, also from the University of Exeter, said: \u2018We need to find out more about whether they deliberately seek out ethanolic fruits and how they metabolise it, but this behaviour could be the early evolutionary stages of \u201cfeasting\u201d.<\/p>\n

\u2018If so, it suggests the human tradition of feasting may have its origins deep in our evolutionary history.\u2019<\/p>\n

So if you find yourself deep in a bender with mates this weekend, you can call it field research into our shared genetic and social pathways. Maybe. <\/p>\n
