Guinea-Bissau - It should come as no surprise that chimpanzees are similar to humans in many ways - after all, they are our closest relatives in the animal kingdom. However, according to a new study from the UK , we apparently not only share certain behaviors, but also a particular fondness for alcohol.

Scientists from the University of Exeter were conducting research in the Cantanhez National Park in Guinea-Bissau, West Africa.

Using a hidden camera, they managed to capture some special footage: For the first time, they were able to film chimpanzees sharing fermented fruit.

These are fermented African breadfruit - and they have been proven to contain alcohol.

The animals were observed eating the fruit a total of 70 times. In ten cases, they passed the treats on to others - and a full 90 percent of these shared fruits contained alcohol.

Particularly interesting: when there were hardly any less fermented fruits available, the more fermented ones were deliberately shared. This could indicate a targeted selection.

"In humans, we know that alcohol consumption leads to a release of dopamine and endorphins and thus to feelings of happiness and relaxation," explained Anna Bowland from the Centre for Ecology and Conservation at the Penryn Campus in Exeter.

It has long been assumed that our early ancestors consumed alcohol not only by chance, but also to promote social bonding.

The current study suggests that reaching for alcoholic foods could be deeply rooted in the evolution of primates - and possibly form the roots of today's drinking and partying culture.
