Plus we have a little thing in our body that digests bones. Supposedly in my biology class, my teahcer was like, that part of the body used to be larger when we were cave men, but now we dont use it, it will eventually evolve and disappear. Yet, I informed him that if everything evolves and disappears, does that mean our toes would disappear, or our pinky's? He didnt know the answer and was like lets move on to the next topic. I eventually gave him the Evolution - Creation book and he thanked me. Dont know if he read it, but its just really bizarre how people think....
