OK, so I was watching The Biggest Loser with my mom (yes, I realize the biggest loser is me, with my mom a close second.) Anyway, some guy lost 16 pounds, and I said, wow, to lose that much weight in a week, I'd have to cut off my arm or something. She said, well, you'd lose more weight than that if you cut off your arm--it probably weighs, like, 30 or 40 pounds. I was like, no way does it weigh that much!

So how much does the average arm weigh? Is there a standard percentage of body weight that an arm weighs? I don't have a severed one lying around handy, and it's hard to weigh an arm that's still attached because it's hard to make it totally slack and not put any extra pressure on a scale w/my muscles. If I weigh 180 lbs, about how much would my arm weigh?

No, I'm not some sarcastic right-wing Christian fundamentalist trying to mock evolution. I'd like for people who know science to prove to me evolution. I know it's not easy to "prove" evolution, but can you at least show me how evolution is the logical solution?
