In humans, there is this concept of general intelligence, which says that if someone is smarter than you then they are smarter than you at all activities that rely on intelligences.
Do other animals also have general intelligences? Or do their brains simply specialize in one area of intelligence. So for example, dogs are considered smarter than cats because they are better at being trained to do stuff. Does that mean that dogs are smarter than cats in all activities that require intelligences, or are dogs simply better at this one thing, which is following instructions from a human?
