As I argued at a dopefest a few months back, I think humans have a unique ability to recognize abstract qualities. The example I gave was that a dog could recognize that there is a difference between a white ball and a white dish and a blue toy. But he wouldn’t come up with the idea that a quality of being white exists independent of the objects and that the ball and the dish share this quality while the toy does not. ---

We know that we think with our brains, which are in our heads. As an aside, I’ve always wondered when in history humans figured this out. ---

> [@Little\_Nemo](#): > > But he wouldn’t come up with the idea that a quality of being white exists independent of the objects and that the ball and the dish share this quality while the toy does not. Some animals can certainly recognize the concepts of color. Alex, the famous bird, once looked at himself in the mirror and asked, “What color?” That’s when he learned the term “gray”. There are also animals that make up songs. Some chimps and bonobos use spears to hunt small animals in holes. Don’t dolphins play catch? I’d say: use of fire, complex tool creation, complex language. ---

> [@zoid](#): > > I asked this question on thew board before and it appears that only humans play catch. In other words only humans cooperatively throw objects TO each other with the intention of having the other party catch it, and the other party has the ability to catch. I’m not so sure about this one, I seem to remember reading about a species that has been observed playing catch. I have it my head that it was a bird, possibly a member of the crow family and they would do this with twigs in the air. However I may have misremembered it. ---

> [@A Monkey With a Gun](#): > > I tend away from that view. It is again, the height of hubris to think that just because we can’t speak whale that they can’t confer thoughts and desires the same way we do. That’s not hubris, any more than it’d be hubris for elephants to think they’re the only ones with an organ that functions like a trunk. Either we’re unique in our ability to communicate an infinite number of concepts via syntactic speech, or we’re not, but it’s absurd to decide that one position is hubristic: that cuts off discussion instead of encouraging it. ---

Forgive me. I didn’t mean “hubris” to apply to you or any others in this thread. What I meant was that humans in general are guilty of hubris in thinking ourselves unique in certain behaviors. We are just _fascinated_ when we see another species do something that is similar to us. We are even surprised by it. That’s where the hubris comes in. We shouldn’t be surprised, nor should we think that we know how other animals think. There are too many animals with too much neural tissue in their skulls (or squid! they don’t even have skulls!) for me to write off anything that deals with the brain as uniquely human. ---

That said, we have had some good answers to the OP’s question. My favorite is still fire. No other animal knows that. ---

How about the idea of combining different types of food to make them taste better? I don’t mean actual cooking here (which I’ll grant not everyone seems to have the knack for), just simple notions like adding salt & pepper to potatoes, or squirting lemon juice on a piece of fish. ---

Barring certain brain injuries, recognizing other human faces. Other species like sheep recognize other sheep by face. Our talent lies in human faces. ---

I suspect that humans are the only animals that willingly do long-term things that hurt like hell in order to achieve a future goal. Examples: dieting, athletic training, medical treatments (surgery, chemotherapy). No other animals use money or its equivalent to foster the exchange of goods. ---

There are too many animals with too much neural tissue in their skulls (or squid! they don’t even have skulls!) for me to write off anything that deals with the brain as uniquely human. Ah I see what you’re saying. At the same time, I think it’s equally possible that we’d ignore some way we’re unique out of a false sense of modesty. If we’re the only creatures with syntactic language, then we are, and it’s an interesting question whether we are; I see no philosophical reason why that’s impossible, so I’d rather approach it from the evidence at hand rather than from any axiom, if that makes sense. ---

Great post / user name combo. And thanks for the info. That eliminates prostitution as being uniquely human.
