The question of what’s uniquely human is a big one and depending on who you ask you might get really different answers.
If I had to put my money on something that was actually uniquely human it seems to be our motivation to actually interact with others in a funny way.
If you see something cool, you say, “Oh hey, look at this cool thing.” And to psychologists this is a process of referring to information out there in the world. It seems like other primates lack at least the motivation to do this. This leads to the fact that they don’t have the kind of communication that we have with things like language with nouns that can kind of point to things out there in the world.
They also don’t seem to share their own desires and intentions with others, which leads to a lack of cooperation in a lot of domains. So if I had to put my money on what was uniquely human I’d go with the kind of motivation to share information with others.
