EDIT: Let’s cool it with the downvotes, dudes. We’re not out to cut funding to your black hole detection chamber or revoke the degrees of chiropractors just because a couple of us don’t believe in it, okay? Chill out, participate with the prompt and continue with having a nice day. I’m sure almost everybody has something to add.
If anything I think emotional response is the least advanced part of a human mind. However, if we’re talking about brains of sharks, small lizards, or ants then I think emotion would be a word with a lot more nuance than whatever it is they do.
The range of what “emotion” can cover is very broad as well. Like feeling good or scared and shame or respect.
I have remind my partner that dogs don’t share all of the complex emotions we do or at least it’s a lot easier to deal with them if you act like they don’t.
I.E. my dog is never going to care if feeding is fair, and they aren’t going to listen to you out of respect about it. They will however eat a certain way because the like being obedient and knowing their place in the pact, but that takes repetition, rewards and punishments.
I recently heard someone make the argument that pain is could intense for simpler animals since they need more explicit punishment for doing dangerous things
We don’t have much way of knowing afaik but it seems plausible
