I was using the word "animal" in the sense of "non-human." The point is that non-human intelligence is particularly difficult and complicated for us to discuss, because no member of our species has experienced it and so we can only reason about it through complex experiments and logic. We can't lean on things like personal experience and language in our investigations of it.
"Artificial intelligence" comes to mind even if what I see from that field is more like advanced pre-trained models, incapable of learning the slightest thing from its failures or successes on its own.
edit: ... but it is a very complicated topic even if most of it isn't even close to anything I'd call actual intelligence.
