Summary:

- Researchers have observed cows using tools, which was previously thought to be a uniquely human behavior. A cow named Veronika was seen using a stick to scratch herself, demonstrating tool use.
- This discovery challenges the long-held belief that tool use is a defining characteristic of humans and suggests that other animals, like cows, may have more advanced cognitive abilities than previously thought.
- The study of tool use in animals can provide insights into the evolution of intelligence and the similarities between human and animal cognition, helping us better understand our place in the natural world.
