ok Holly, I'll step up to your "challenge".

in ancient times, when you did not have the benefit of simply opening the refrigerator or cupboard to get some food/snacks, and assuming you are a young child, if your parents were to hear your stomach growling they would know you are in need of food.

i challenge your challenge (this is getting challenging!). The stomach does not always growl from hunger. More often than not it growls as the digestive process begins and muscle contractions (called peristalsis) begin to move the food and air into the digestive tract.

I don't snore (so I'm told), but I do talk in my sleep.  Apparently, I talk loudly in my sleep.  I also curse at people in my sleep, so I'm told.  What would be the evolutionary reason for that?

That's easy. From an evolutionary standpoint, it's advantageous for a male to spread his DNA among as many females as possible. This is nature's way of ensuring that you never stay mated to one woman for very long.

I've read that men snore when they lie on their backs because their balls fall over their asshole and they vapor lock.
