I thought natural selection was to place the baby in front of the fire, if he sticks his hand in the pretty warm light he gets hurt and never does it again, if he does it again after getting hurt... well... out back
No, natural selection is the name that we use to describe the fact that only organisms who are adapted to their environment survive long enough to reproduce. Using your example -- if a kid keeps sticking his hand in the fire no matter how much he gets burned, he will lose both his hands (and maybe more) before long, which will make him incapable of performing most tasks as well as visually unattractive to opposite sex. As a result, he most probably will not find a mate to have a baby with, effectively making the line of people with fire-happy genes extinct as soon as he himself dies.
