Shouldn't evolutionary forces have given us an urge not to itch? That is, those that itch are more likely to get sick and die (infection perhaps?) and not have offspring who also itch. Meanwhile those without this itching urge live on to have non-itching children.
Maybe itching is actually the thing to do, maybe it's good for you after all?

itching benifits is to discover the bite

It's not exactly "bad" Sometimes people just get carried away and scratch too hard and it breaks the skin. Or dirt and bacteria are in your nails and it seeps into the initial wound. Itching is natures way of alerting your body that a bite or reaction has occurred. Our natural instinct is to itch. And thats ok as long as you don't overdue it and your hands are clean

99.99% of the time people scratch an itchy mosquito bite and nothing bad happens. The itch is relieved. So there's no need to evolve out of the scratch reflex. It serves a good purpose. Maybe the real evolution is to have the body not react to the mosquito bite with a histamine reaction, since it is 99.99% harmless anyway.

I don't know how advanced itching something that itches is. Seems pretty primeval to me.

scratching is not a bad thing...but when a mosquito bites you, it injects its infection....and if you scratch, you will spread the fluid and the infection as a result!
so scratching is not bad when you dont have an infection! :)
