As I have worked with mutant and knockout mice I thought this was a very interesting article.
Amazing the stuff we can do with science these days. It also just amazes me how fragile the world is and how the tiny things are what really decided what and who you are. One tiny gene was turned of and we all of a sudden have a Pinky and The Brain phenomenon on our hand.
