I always felt our creator is unfair. Why he cannot create human with wings? Now I can tell you why, it is so our Scientist can breakthrough DNA code and make everyone unique, different.
Today in news a UW-Madison Science team found Sonic Hedgehog, genetic digits that make hexadactyly. Think about the possibility once every code is discovered, you may like to grow a unicorn horn on your son’s head, or gives your daughter a pair of fin on her back. DDI! You can create a whole your human race.
You tell me. (Link)
