Humans, birds, and other creatures share a set of genes that lead to the development of fingers and other digits (like paws or wings), but the way those digits form has been a mystery. Now a group of researchers in Wisconsin have discovered the secret of digit growth, and perhaps the key to regrowing severed or stunted fingers. It's even possible this research would allow you to grow an extra finger or two. This might make working with your hands easier, or lead to strange biopunk fashions that involve fingers sprouting from your head.
The best part is that one of the genes involved in finger-creation is called Sonic Hedgehog:
Yeah, wings would be tons better than an extra finger. I don't feel I need anymore fingers but being able to fly, assuming having wings will allow us to take off, would be useful for getting to one place to another.
Extra finger would be handy when playing gutar hero hehe!! wings would be fun though and maybe our window cleaner would get the job done a little better than he has been!
