animal intelligence

“We cannot (and do not) make any claims about how intelligent they are.”
Intelligence is a complex subject but let's get one thing straight, dolphins aren't dumb. The question about which species are the 'smartest' fascinates us. Our answers will always depend on human-derived value judgements associated with the merit of different attributes...
I argue that dolphins do in fact display startling skill in some of the areas we associate with intelligence, like symbol use and social cognition. But I also argue that when we put dolphin intelligence in context by looking at the intelligent behaviour displayed by other species... the argument for dolphin intellectual superiority gets doused with a bucket of cold, salty water.
To function like name-use in human language, dolphins would need to not just repeat their own name, but call out the names of other individuals in order to address them. Figuring out if dolphins do this has been the goal of Vincent Janik and his research group at the Sea Mammal Research Unit at the University of St. Andrews.
