For generations, the ability to craft and utilise tools was widely believed to be a defining characteristic that set humans apart from the animal kingdom. This long-held notion, however, may need a significant revision, thanks to the remarkable ingenuity of a Swiss brown cow named Veronika.
Veronika, who resides in Austria, has apparently taught herself a rather sophisticated trick: using a broom to scratch those hard-to-reach itches. This behaviour, observed and studied by biologist Antonio J. Osuna-Mascaro, marks the first documented instance of a cow exhibiting tool use.
A Cow’s Ingenious Solution
The study, conducted in Veronika’s paddock, revealed a surprising level of flexibility in her approach. Veronika didn’t just mindlessly wield the broom; she adapted its use based on her specific needs. When a more vigorous scratch was required, she would opt for the stiffer bristles. Conversely, for a gentler sensation, she would cleverly reverse the broom, employing the rounded tip.
This nuanced application of a tool is what makes Veronika’s behaviour so significant. As Osuna-Mascaro explained to the BBC, the only comparable well-documented case involves chimpanzees. He cited the rare instances where chimps have been observed to fashion tools for fishing termites, utilising both ends of a stick to achieve their goal.
While tool use among primates has been extensively studied and documented, cows, despite their evolutionary proximity to humans, have largely been overlooked in this regard. Osuna-Mascaro emphasised the broader implications of his findings:
“It is important to know that cows have the capacity to innovate in their use of tools and to use them flexibly, because this sends a strong message about how biased we have been regarding cows’ intelligence and their capabilities.”
Beyond the Herd Mentality
Veronika’s life story is also somewhat atypical for a cow. She is kept as a pet rather than being part of a larger herd. This unique upbringing may have fostered an environment conducive to independent learning and problem-solving.
Osuna-Mascaro is keen to hear from others who may have witnessed similar instances of tool use in cows. He highlights the core element of such behaviour: “The key element is this: grabbing a free-moving object and using it as an extension of oneself in order to reach targets that would otherwise be difficult or impossible to reach.” This definition distinguishes true tool use from simpler actions, such as scratching an itch on a fencepost.
A Shifting Scientific Landscape
The idea that only humans possess the capacity for tool use began to unravel in 1960. The pioneering anthropologist Jane Goodall, during her observations of chimpanzees, documented them using blades of grass to extract insects from termite mounds. This groundbreaking discovery opened the door to a wider understanding of animal intelligence and behaviour.
Since Goodall’s seminal work, tool use has been observed across a diverse range of species. This includes:
- Fish: Certain species have been seen manipulating objects to their advantage.
- Birds: Various avian species demonstrate remarkable problem-solving skills using tools.
- Reptiles: Some reptiles have been observed using objects in their environment.
- Octopuses: These intelligent invertebrates are known for their complex behaviours, including tool use.
- Elephants: Known for their intelligence, elephants have been observed using sticks and other objects.
- Sea Otters: Famous for using rocks to crack open shellfish.
- Mongooses: These agile mammals have been seen using tools to access food.
- Honey Badgers: Also known as “ratels,” they have demonstrated tool use in various contexts.
Osuna-Mascaro’s research, which sheds new light on the cognitive abilities of cows, has been published in the latest issue of the esteemed scientific journal Current Biology. His findings challenge our preconceived notions and underscore the need for a more open-minded and less anthropocentric approach when evaluating the intelligence of other species.
