It isn’t just humans who like to drink alcohol As a review of published evidence has revealed, animals also partake in consuming the substance.
“The evidence is mounting that humans are not drinking alone,” the writers noted in their work. Trends in Ecology & Evolution .
This occurs due to the natural presence of alcohol in every ecosystem out there. planet , so it’s likely that many animals consume plant-based foods like sweet fruits.
Similar to us, different species have varying abilities when it comes to dealing with alcohol’s impact. Some creatures can safeguard themselves and even derive energy from consuming alcoholic substances, whereas others struggle more with handling its effects.
"We're shifting our perspective from the human-centered idea that only people consume alcohol, towards recognizing that ethanol is surprisingly common in nature," stated Anna Bowland, a member of the research team at the University of Exeter.
In this study, researchers found a "varied group" of species that incorporate ethanol into their diets due to feeding on fermented fruits, sap, and nectar.
When was ethanol initially introduced?
Large quantities of this substance first appeared on Earth a very long time ago (to be precise, 100 million years back).
This substance might be discovered in flowering plants that yield sweet fruit and nectar, both of which can undergo fermentation by yeasts. The alcoholic content varies based on how ripe the fruit is. Typically, it ranges from about 1% to 2% alcohol by volume (ABV). However, when the fruit becomes overly ripe, the alcohol level could rise dramatically to around 10% ABV.
Can you provide some instances of wildlife known to ingest alcohol naturally in their environment?
Spider monkeys in Panama feed on yellow mombin fruits containing between 1% and 2.5% alcohol, according to research findings. Meanwhile, wild chimpanzees observed in southeastern Guinea have been spotted consuming the fermented sap of raffia palm trees.
Can animals get drunk?
Stories abound about intoxicated creatures, like "elephants and baboons getting tipsy from marula fruit in Botswana, or a moose discovered with its head trapped in a tree in Sweden following an encounter with fermenting apples."
Nevertheless, the level of alcohol detected was not present in the animals or the fruits in these specific cases.
It might shock you to know that many creatures can handle the substance rather well.
Experts discovered no proof that pen-tailed treeshrews get intoxicated despite their "substantial ethanol intake," yet it remains unclear how one might observe the behavior of an inebriated treeshrew.
Researchers found that creatures capable of processing alcohol swiftly usually consume fermented edibles; however, this speedy metabolism might come with certain drawbacks.
Consider the Cedar waxwings, which feast on the fermented berries of the Brazilian pepper tree. As they process the alcohol from these fruits, they become disoriented and end up crashing into barriers like fences, leading to their deaths—what one might call avian drunken flight.
Bowland pointed out that intoxication does not serve well when you're struggling to stay alive,
When people face rejection from someone they're interested in romantically, many might turn to alcohol – much like how male fruit flies respond to being refused as mates. Who would have thought?
When under the influence, females from a similar species become less selective regarding partners and engage in sexual activity with multiple males.
One of the most notable impacts of alcohol can be observed in insect behavior. When male fruit flies get turned down as partners, they seek out alcoholic substances. Conversely, female fruit flies from a similar species tend to lower their standards for mating choices and engage with multiple males post-drinking. Additionally, fruit flies choose to deposit their eggs in food sources rich in ethanol, which helps shield the larvae from parasitic infestations.
So now, the genuine query arises... Which type of creature has the highest tolerance for liquor?
It was found that Oriental hornets are the most adept at handling such conditions, since researchers under Eran Levin from Tel Aviv University revealed last month that these insects might be the sole species capable of consuming limitless amounts of alcohol without experiencing any adverse effects (in contrast to human beings).
“They can ingest up to 80 per cent ethanol solution without any negative effects on their mortality or behaviour,” said Dr Sophia Bouchebti, a co-author of the study.
“Besides the fruit fly, aye-aye, and slow loris, it remains uncertain whether animals have a preference for foods containing ethanol,” stated Matthew Carrigan from the College of Central Florida, who was also involved in the review.
He mentioned that among the "subsequent steps" for this study is to investigate whether "wild animals opt for foods containing ethanol or consume them solely when ethanol concentrations are too minimal to be detected, or when unfermented fruits become scarce."
One of our upcoming tasks is to determine if animals in their natural habitat show a preference for foods containing ethanol, or if they consume such foods solely when ethanol levels are undetectable or when non-fermented fruits are scarce.
