No opinion pieces, Listicles, editorials, videos, blogs, press releases, or celebrity gossip will be allowed. All posts will be judged on a case-by-case basis. Mods may use discretion to pre-approve videos or press releases from highly credible sources that provide unique, newsworthy content not available or possible in another format.

7. No duplicate posts.

If an article has already been posted, it will be removed. Different articles reporting on the same subject are permitted. If the post that matches your post is very old, we refer you to rule 5.

Misinformation / propaganda is strictly prohibited. Any comment or post containing or linking to misinformation will be removed. If you feel that your post has been removed in error, credible sources must be provided.

9. No link shorteners or news aggregators.

All posts must link to original article sources. You may include archival links in the post description. News aggregators such as Yahoo, Google, Hacker News, etc. should be avoided in favor of the original source link.

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.

Yes, I agree, in just pointing out how difficult is to understand that. Theoretically, it's not like a human-level intelligent insect couldn't exist.

My thinking to challenge myself/ourselves: Then how do whole colonies decide and plan resources? When to gave truce or war with the neighbouring colonies (of same or completely different species?). Their war strategies resemble human wars without technology/weapons. They also cultivate insects, plants, and fungi. Some within colonies plan, deceive, and try to develop a new queen (instead of the queen doing it in purpose/strategy).

Having brains as such imho is part of the problem as it adds a lot of complexity for humans to relate to.

But even our brains don't work and govern alone, major organs have a complex nervous systems of their own (complex in the sense of not having a centre).

Not as a direct comparison to insect, but eg cephalopod brains are also vastly different, yet clearly highly intelligent.

We understand most of your questions quiet well. It's been a long time since I studied biology and I'm not working in that field anymore so I won't be able to give you most answers from memory, but if you are interested you will find a lot of research on those topics. It's mostly really rather automatic responses through pheromone systems with involuntary responses. Especially the wars of ants are quite well understood in that regard.

Cephalopod have different but also rather complex brain structures. Again - insects just completely lack higher brain anatomy. If you into those question I would highly recommend you to take an introductory lecture into neuroscience online. We don't understand everything but we understand some things quiet well.
