What is the evolutionary advantage of pain...

What is the evolutionary advantage of pain? Surely pain could simply be replaced with something less excruciating like anxiety and the end result would be the same?

If it wasn't excruciating, it wouldn't work as well.

pain is your body telling your brain
that is has made a bad decision

Nerves just werk. Theres no ingame settings for life to make stubbing your toe less shitty. If getting mauled to death by a lion isnt the worst thing then you have less incentive to not let that happen.

Well let's see, what you you think will keep a criter alive long enough to breed? Burning alive in a small fire, or merely being close enough to the fire to stay warm, but not burnt up? Or how about a guy who can run super extra far with a stick jammed in his foot, or the guy who stops walking to remove the stick? Or how about a big ass sabertooth tiger chewing on your ass? Would the painless victim have an advantage in a physical fight vs the victim who fears pain more then anything, so he runs away?

Now I'd say it'd come down to how long you need to stay alive to have kids, and the method of reproduction. Bit of pain will keep you alive in the long run, but a lack of it could keep your kids alive if you have to defend them. If you are actually a smart criter and know about long term consequences of what you are doing, and weigh them vs the short term risk, ignoring pain can be a good choice. Infact I bet ignoring pain is a key part of evolution, the weakest animals will just lay about in pain, while the big Chad animals will play though the pain getting more chicks. Thus passing on any sort of genetic bias for having pain. A painless criter could to fight longer and harder, but most likely die sooner because of it. So the trait selecTed for is ultimately having pain, but being smart enough to know when to ignore it.

Are you smart enough to know the difference between pain that will kill you and pain that will just hold you back?

Bigger question is what's the evolutionary advantage of consciousness? Why didn't evolution make us all p-zombies?

Consciousness isn't a product of evolution. It precedes it. Evolution works with consciousness. It's pretty much a singularity's algorithm for achieving infinity.

Are you talking about physical or emotional pain because they're two very different things.

Just imagine, for one second, posting something this stupid - and revealing what a teenager you are in the process.
