All three of these discoveries came in the last five years — indications that the more scientists test animals, the more they find that many species may have inner lives and be sentient. A surprising range of creatures have shown evidence of conscious thought or experience, including insects, fish and some crustaceans.
That has prompted a group of top researchers on animal cognition to publish a new pronouncement that they hope will transform how scientists and society view — and care — for animals.
Nearly 40 researchers signed “The New York Declaration on Animal Consciousness,” which was first presented at a conference at New York University on Friday morning. It marks a pivotal moment, as a flood of research on animal cognition collides with debates over how various species ought to be treated.
I dunno about all that, but I used to have an African fish that would always get the zoomies when I'd come home from work. He'd spit water at me or gravel at the glass to get my attention, and loved playing hide and seek and always brushed up on my hands when I was working on his tank. He never reacted this way to visitors, just me.
And to get to this you need experience, research, and knowledge.
And trying to explain this to humans in general would take several generations in best case scenario (much less actually doing/changing anything with that knowledge).
Usually anything attacking the doctrine of how extra super special & way more unique than other equally unique species are is meet with severe (auto-?)hostility.
Even without our status in question, just the "threat" of something being slightly less/differently inferior to us is immediately attacked by the vast majority.
And once we decide something is inferior to us it takes extra effort to change the popular belief (like racism between humans as well - just designate some human as non-human & they are considered about as much as billions of yeast bacteria as we are baking bread).
I think the auto-hostility is just hubris. Some people would like to pretend they know everything about everything. So when learning new things they get hostile because, oh no, we found them out.
