Only god knows

Are humans the only animal to grow pubic hair?

What the heck kind of ignorant question is that?

Are humans the only animal to grow pubic hair?

I don't know if you'd want to call it pubic hair but if you notice, bulls have some kind of proliferation of hair around the opening of the penis.Pubic hair is like a billboard that nature places on our bodies that signals "hey! look over here!" to others with whom we're intimate with. Also, all our hair (no matter where) helps to protect certain parts of our body, regulate body temperature, and/or catch our natural "scent" (called pheromones) that is produced in our sweat to attract others (of course, this "scent" can also repel others if we don't shower often enough!). General body hair, like on our limbs and chest, is probably just a natural leftover from our prehistoric ancestors who were hairy all over to keep them warm!

Are humans the only animal to grow pubic hair?

All mammals (even whales) have hair or fur. I imagine most have hair or fur that covers their nether-regions, but I don't think I'd call it "pubic hair."

Some scientists think that pubic hair (in mammals in general) helps trap pheromones used to signal readiness for mating.

There is no known benefit to male pattern baldness (maybe fewer trips to the barber shop?). It's just an unfortunate allele that affects men more than women. Men need only one allele from either parent to have male pattern baldness, whereas women need to inherit two alleles (one from each parent) to display pattern baldness.

No. Almost all mammals are covered with hair. We have just lost it in most other parts of the body.

The primary benefit is the retention of odors, which, in dilute concentrations, are attractive to the opposite sex.

Male pattern baldness probably has no evolutionary benefit. However, because its onset often comes after the man is past breeding age (or at least after he has paired up), there is no great evolutionary penalty. If male pattern baldness started in the early teens and if women were repelled by it, there would be sexual selection against male pattern baldness and it would gradually decrease in frequency. As it is, there is no great selective pressure either way.
