Itching makes no sense to me.
From a Darwinian, species selection point of view… just what good does itching do for us? Pleasure, pain, sneezing.. I get all that. But itching?
Oh I know its probably whatever has infected, bit, grazed us is trying to get us to spread itself or create a better habitat for its survival. But has our genetic code let the bugs have THAT much control after millions of years of evolution? Really?
And a healing cut.. why does that itch? It’s detrimental to scratch it when it itches because the skin might tear or we might get dirt and bugs into the wound… so why? Why would the specimens who scratched survive at all? Wouldn’t they die out over the ones that didn’t? Are you telling me that in millions of years of evolution there wasn’t born a few humans who DIDN’T itch and therefore didn’t scratch?
Then again.. there are still people on Larry Springer, so maybe evolution isn’t as smart as we think i t is!?
