Humanity as a whole is qualitatively different than anything else I can think of. I think this is obvious. But how different are humans? If you take a homo sapien in isolation and a chimpanzee in isolation (I know there's no such thing but for the sake of argument), how much difference is there really? Biologically it's not much. Even neurologically, we've basically got the same hardware with a bit more bandwidth for sensory processing, and a bit more processing power for higher order functions like planning and analysis. The archeological record would seem to indicate that it took many tens of thousands of years for these minor fundamental differences to develop into something obviously qualitative. Whether you call these fundamental differences qualitative or quantitive to start with seems like a pretty subtle difference of perspective.
