What are some things that all humans know but no other species does? For the sake of argument, we don’t have to include humans with various medical disabilities, such as being in a coma.
For instance, we all know how to swallow. But so do a lot of other animals.
Eating crap is something that should be done in private
Where beef comes from
That the world is larger than the distance that we can walk
That thumbs are special
It’s also not true. Whale language. Other species exhibit similar behavior as well.
I’ve said it on the board before, but there is truly little that sets humans apart from the rest of the animals. Take tool use for example. We are far better at it, but it is far from unique. Human hubris makes us want to think that things like tool use and language are unique, but they simply are not. We need to be a little more humble.
Believe me, I’m not trying to threadshit, but this is a very tough question. I can’t think of a single damn thing that ALL humans know that no other species does. I’m wracking my brain and I’m coming up with nothing. Everything I can think of has either animals knowing it in some form (language, tool use, problem solving, etc.) or not all humans knowing it (higher level math, what the moon is, etc.)
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.
Chimps slinging paint at a canvas or an elephant smearing paint with its trunk don’t cut it. Only humans can pick up a pencil or a paintbrush and produce a picture that is recognizable by others. Only humans can compose music, poetry or prose.
I dunno about the language thing: the ability to use a language grammatically is something that has not been convincingly shown in other species. The linked article about whalesong is pretty preliminary stuff and contains no information about the meaning of any whale syntax or indeed whether there’s any meaning there. It’s perfectly possible that whalesong contains no clear message communicated via syntax.
Can a whale say, for example, “The food in this spot is better today than it was yesterday, but I still wish there were some mackerel around here”?
Steven Pinker, in The Language Instinct, has a lovely passage describing the uniqueness of the elephant’s trunk. He says there’s nothing else in nature quite like that trunk–and that if elephants were biologists, they might claim that possession of such a trunk was of central ethical importance. He argues that in the same way, our ability to use language is unique in nature, and that making such a claim is no more remarkable than making such a claim about elephant trunks.
And that’s a VERY good one. I’m kicking myself for not thinking of that earlier. Art is debatable, but fire is probably the one single activity that does set our species apart.
There’s some kind of prairie dog that can say “Hey, here comes the human in the blue shirt”, Hey, here comes the human in the red shirt", and “Hey, here comes the human in the blue shirt, but today he’s wearing the red shirt.”
But I’m sure that they can’t discuss more abstract ideas. That could very well be uniquely human.
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. It sounds like Mr. Pinker is saying that human language is unique, and since no other species speak human language, they don’t communicate well at all.
