Gotta join the chorus here. I'm not sure why anyone's surprised to find that something with functioning neurons can feel pain. Wild guess, because I'm not a neuroscientist, but that's gotta be one of the very first things they were ever responsible for conveying, right? "Ouch, don't" has pretty universal utility.

Has there been a consensus somewhere that insects (in the animalia kingdom along with fish, birds, reptiles, mammals (humans), etc) do NOT feel pain? I thought everyone knew that intrinsically.
Who thought they didn't?
Probably the same peotle that burned insects with magnifying glasses
Nope, we called that killing them.
Why would any animated being run away from danger if it didn't feel pain? It should be assumed that animals feel pain. Pain keeps them away from danger, so they survive, and evolve with those pain genes. For plants however, whether they have pain genes or not doesn't matter for their survival so they evolve either way.
I don't think tending to damage is enough to prove pain.
Microbes detect and move away from danger. Plants detect danger and react to defend themselves. They also redirect resources to heal. Pain isn't necessary for this.
Pain is for learning, so you avoid what caused the pain. Beings that don't learn shouldn't feel pain, it would just be a waste of energy. That'd only happen in evolutionary quirks (ie loss of capacity to learn after gaining pain). Nature is cruel (grasshoppers get their heads eaten during mating) but not just for the sake of it.
And of course, there's humans that have a condition that makes them not feel pain. They still learn self preservation, and they have some reflexes too.
The article makes the comparison with a hurt dog. Dogs remember for life what hurt them. It's very obvious they learn from pain.
Pain is a detection of danger. If burning felt good, microbes, plants and animals wouldn't turn away.
Your body does a whole bunch of things in reaction to danger that don't register as pain. Sweating, contracting pupils, releasing insuline...
You could get philosophical and say that these are pains of your body's subsystems. And if microbes can feel pain then your body functions on the misery of billions of beings trapped inside of you. Not really something you can build a morality on.
Well what we feel as pain is ultimately chemical reactions. Now I can't go into the entire set of chemical reactions that another being would qualify as "pain", much less hypothesize as to what word another being would qualify anything. I'll leave the spectrum of chemical reactions and non-human pain thresholds to others.
I really don't get the idea that people don't think animals or bugs feel pain or distress.
Like if it's got a nervous system I'm sure it has some concept of pain.
Many insects don't have a nervous system. Also, some plants respond to physical damage (albeit very differently than an animal) and they don't have nervous systems, either.
It would also be possible to build a machine that can detect damage to itself and program it for self preservation, but that doesn't intrinsically mean it would feel pain.
What insect doesn't have a nervous system?
If it bites me I'm killing it, self defense. I don't care about its pain. It doesn't care about mine.
Also the fact that bug's are silently going extinct and nobody cares to notice, seriously stick your head out the window right now and listen, that is a silent apocalypse my friend.
I opened the window and a wasp came in.
Now I'm selling my house.
I wish some bugs would go extinct, bed bugs, mosquitos, ticks, maybe yellow jackets. Seems like those populations are strong than ever.

For what it's worth, my totally non scientific personal experience is that in Denmark, the number of insects that I have to clean off the car has trended upwards in the last two years
I could make aong crazy post about this. This is bad. I wanted to be an entomologist my whole childhood and i consider myself an amateur one. There are no bugs. Where there should be ants and earthworms, there are none. After a rain worms should be all over the place, the castings should be found everywhere. I keep looking and they are not there. I went to at least 20 lakes last summer in my canoe fishing with my kid and looked for aquatic insects. There are none. So there are so small fish. So there are no big fish. I just went all over florida just last week, i saw a couple of butterflies. No mosquitos, no ants, no spiders, no anything. Every year my building is really close to lake erie and gets covered in insects in the spring, havent seen a single one. I keep looking and haven't found anything.
I remember road trips in the summer, in the 90's, where you'd just see a bunch of bugs splatter on your windshield, and where you'd have to periodically scrub them off with windshield scrubbers.
Now, 25+ years later, I almost never see bugs on bumpers and hoods and side mirrors. Certainly not to the same degree.
And I can believe that computer aided design helped make all cars much more aerodynamic so that fewer bugs would actually be hit and more would slip into the airflow around the car, but the sheer magnitude of the dropoff makes it totally obvious that there are just fewer insects around.

I'm not sticking my head out the window right now. It's covered with termites.
Pain is probably one of the original sensations. I doubt you could find any creature on Earth that doesn't feel it. It is extremely useful for staying alive. I bet we will find out plants even feel some form of pain if we haven't already.

I lovr how there are a half dozen or so "well obviously duh' comments in here each with a half dozen or so replies all stating 'well not so obviously'
