At a high level this is true, but at a basic neurological level it is not. Neurons operate the same in humans and in buterflies, and at this level learnng most certainly does take place in almost all known animals. >Perhaps the crux of this problem is the definition of "learning" as >a purely behavioural one. IMO, learning is more than just displaying >certain behaviour. yes indeed, you seem to be using a very different definition of learning than most biologists. As a trained bologist, I would sya that the standard definition of learning runs something like this: A change in neurological responses due to repeated stimulus that tends to alter behavior in a way that is responsive to changing environmental situations. [Note this is only an aproximation - I do not have the formal definition handy] By this definition the example with the buterflies is a *clear* and *definitive* example of learning. >Agreed, if you look merely at the behavioural aspects of learning. Otherwise, >maybe there's little similarities between the exhibited behaviour in humans >and cats. Not just the behavioral similarities, but also the identity of basic neurological mechanism. Even if the *cognitive* processes are different in humans, cats and buterflies, the neuronal mechanisms are still the same. >>But, by my everyday definition of "intelligence", cats and crows and many >>other birds and mammals certainly have it. > >How do you tell?

You may be right, but the question is: beyond >behaviour, what differentiates between the intellegence (learning) and >non-intelligence? I would distinguish between learning, which is shown by all forms with a nervous system, and intelligence which involves creative behaviors - the initiation of new behavior by mechanisms other than simple trail and error. This includes anticipation, modeling, improvization, recombination of behavioral primitives & c. Cats show the latter, as well as learning. I have never observed un-programmed behavior in any insect, so I doubt that any insect is particualrly intelligent. >>Their "intelligence" does not >>seem to be as elaborate or as developed as ours.

It is both! Just what do you think 'learning' is? It is a `software' design to increase adaptability, and thus survival, by allowing behavior to be modified by past experience. Learning is *primarily* a behavior designed to acquire food (and escape predators, and ...). Indeed in these examples not only do the birds show learning, they show intelligence. > >Agreed.

I do not think anyone is claiming *equivalence* in learning or intelligence, just that it exists to various degrees in many animals. Intelligence is not an all or none thing, it is a measure of tendency. Some entities have more of this tendency, some less. Humans appear to have an order of magnitude more of it than anything else, but cats still have more of it than butterflies (and probably more of it than dogs) >>And finally, is the domain or goal of "Artificial Intelligence" really >>"Artificial HUMAN Intelligence" ? >We haven't positively located any other species that is intelligent, so >we have only ourselves to base creating intelligent systems on. I'm not >saying there isn't other intelligent species (to a greater or lesser >degree than us), just that we haven't identified them yet. Perhaps by your definitions. But most biologists would disagree. We know of many relatively intelligent species, some more so, some less so. The porpoise appears to be second only to humans with the chimpanzee in the same general vicinity. If you wish to use different definitions of intelligence and learning than biologists and psychologists, feel free to do so. But then you should try to give us a clear specification of *your* definition, so we can talk the same language.
