I hope this means I can alter my genes and grow scales as my eyebrows!

Seriously though, what this clearly shows is, a few minor genetic differences is all it takes to change feathers to hair, or scales to feathers. All they let out of the bag is, an unnamed molecule was the trigger for change. But out here in the real world, we are all a mutation or two from having feathers instead of hair.

Evolution for the win.

Creationism, schmee-ationism.
