Biologically speaking (and I believe in evolution) - underarm hair traps our body odor including pheromones - which help attract members of the opposite sex. since we evolved to use our arms much more than our legs, the hair acts as a sort of anti-friction padding, so our underarm skin doesnt become raw and chafed. Talk this over with a female gymnast sometime, they have to use powder and/or plenty of lotion to keep from chafing if they shave their pits and if its a European female gymnast that doesn't shave, she usually doesn't have any chafing problems.
