Is There a Limitation to What We Can Learn From Human Studies?

The brain is just so incredibly complex and there's so much that we don't understand about what is contained within our skulls. Do you think there's a possibility that actually other species are equally complex equally fascinating in the way that their brains work it could be quite different to humans. I'm skeptical about the potential for so-called artificial intelligence to overtake human intelligence this idea that computers might soon be able to think like human being or maybe even surpass.
