#12: An Extra Tooth For Good Measure
If I’m not mistaken, things like this are common, but that doesn’t make them any less fascinating. Amazingly, a simple programming error can affect our bodies for our entire lives. It’s like when you accidentally build something wrong in Lego, but if the Lego was alive.
The only disappointment is that for all the people born with extra toes, teeth, or hands, it seems incredibly rare that the extra appendage is useful. I’m willing to spend a lot of money to bet that this roof-of-the-mouth tooth we’re talking about is completely and utterly useless.
