Far more animals than previously thought likely have consciousness, top scientists say in a new declaration — including fish, lobsters and octopus.
Bees play by rolling wooden balls — apparently for fun. The cleaner wrasse fish appears to recognize its own visage in an underwater mirror. Octopuses seem to react to anesthetic drugs and will avoid settings where they likely experienced past pain.
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.
We have fossil evidence otherwise. Their greatest barrier to developing higher intelligence is that they die after reproduction, so they’ll never have pressures to develop more symbolic thought or pass on knowledge.
Octopuses are mostly antisocial anyway and wouldn’t want that. Squid, by comparison, use they high intelligence for social interaction but most of it is trying to navigate a social setting where you want to eat as much as you can, mate with your neighbors, and avoid offending your neighbors enough that they eat you. There’s still only so much you can do when you die after a year or two because of a biological time bomb that kills you with sex hormone overload.
