You do not understand evolution at all... I will explain
Evolution starts with small, random changes...
If the change is beneficial, the person will live longer, and have more sex, more children, spreading their genes
If the change is not beneficial... the person will die sooner, and not have many children
Great explanation... assuming it's true, can you please tell me who is in charge of these small random changes?
Please do not mention chance because I've never seen a piece of iron evolve into a pin ALL BY ITSELF!
