Ryan posted a link to an interesting article on the intelligence of pigeons and baboons. It seems that recent studies have shown these creatures to be smarter than was realized. This leads some researchers, such as University of Iowa professor Ed Wasserman, to conclude that there is no fundamental qualitative difference between the minds of animals and humans, but only a quantitative one, and that only human arrogance makes people think otherwise. As for myself, I shall only be convinced of this when I hear of pigeons and baboons conducting such studies.
