Why do people have hairy ass cracks?

All ass hair does is cause dingle berries. You would think that evolution would do away with ass crack hair since it becomes an unsanitary breeding ground for bacteria that could endanger a human's life.

Its probably for sweating

We have hair in those areas to reduce friction between the skin surfaces.

It's also preforms a number of other minor functions, such as trapping sweat and bacteria for pheremone production.

Women have less body hair than men.
Are you implying they are "more evolved" (only creationists consider things more or less evolved) than men?

Why do women have hairy vaginas?

All it does is cause urine droplets to collect. You would think evolution would do away with vaginal hair since it becomes an unsanitary breeding ground for bacteria that could endanger a human's life. Not to mention it makes it harder to reproduce.

Bacteria are vital for us, you're already infested with them and you'd die if they were taken away.

Remember that russian informer who got poisoned with polonium? He died eventually simply because his entire digestive tract was cleared of all bacteria and he starved.

Even the ones inhabiting your skin have a multitude of uses.

The average animal will reproduce in about a year, by the time you read this bacteria already has.

You'd die, but your body wouldn't decompose because bacteria do that too. So yes, life would suck if not for micro-organisms. A cold every so often is a small price to pay for a world that's not full of corpses and dead plants.

Wait. If micro-organisms don't evolve, answer these questions three:

1. How did multicellular life-forms come about?
2. Why can we not cure certain ailments, e.g. the common cold?
3. How can micro-organisms develop resistance to certain drugs?

The reason we have genital hair, ass hair, armpit hair, etc. is because they function as scent-traps for our scent glands. But we only have scent glands in our armpits now. The only reason I can think of why we might still have scent-trapping hair is because it produces a visual sexual signal rather than a scent. I hate having ass hair though, it's fucking annoying,
