The evolution of pain.

[Anomalocaris]

My 2 brain cells have collided again and got me thinking about this.
What is pain and why do we need to experience it?

Does feeling pain give an evolutionary advantage?
Animals naturally hunt and kill each other for food. Do those animals feel excruciating pain whilst literally been eaten alive?
Why would nature make us suffer like that?

Is it a compromise nature makes because a better system couldn't evolve?
Why do I ask lots of fucking questions?

Because nature doesn't give a rat's ass about you.

you, on the other hand, owns your very existence to your ability to suffer.

You see, if the gene pool that otherwise would have been made you did not contain the wiring for pain and suffering, then that gene pool would probably not have been passed on to make you. The reason is creatures made from genes that does not support pain and suffering would be less likely to learn to avoid injury from new circumstances. So they are more likely to have dies before passing on their genes. That means if your ancesters lacked the genes to suffer, they would have died before passing on their genes to you.

So say thank you to the wiring in your brain that enables you to suffer pain next time when it hurts.
