Well, we get all involved in the forms, differentiating between aardvarks and, say, wild boars. But in terms of their imagninative abilities, their internal landscape, maybe there are not fifty million different types, but a continuous gradation of degrees of ability, as a separate set of variables from brain function or number of synapses, etc. Thus some horses (with medium brains) act much smarter than some people with large ones (relative to body mass). Likewise some dogs can outsmart some cows. But not all dogs, and not all cows.
