Scientists push new paradigm of animal consciousness, saying even insects may be sentient (www.nbcnews.com)

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.

"Same" neurons (they don't have all the neuron types we have but in general one can say it's the same neurons), just no complex brain structures. You can have very complex behavior completely reliant on pheromone systems, quite well studied in ants. I'm not to familiar with bumblebees so I would need to look into literature, but for example simple learning already happens at molecular level and does not require any thinking at all.

They show evidence of a degree of culture (socially shared knowledge)

Came around to read the paper. Indeed very interesting - also not suited to base broader conclusions about coinciosness in insects in my opinion, the idea that culture might be supported by much simpler neuronal mechanisms is fascinating to me. Very speculative it might very well be than that even coinciosness can emerge in less complex systems then previously thought. Also bumblebees are even more dope than I previously thought. Great read thanks.

Thanks, will check the paper out.
