Chickens Grow 'Dinosaur Legs'

(Credit: ap./Flickr) It may not be Jurassic Park, but it's certainly a step in that direction. Scientists from the University of Chile have successfully created chicken embryos with a unique feature: dinosaur legs. Don't imagine chickens stomping around with giant Brontosaur legs, though — the changes are all internal. The feature in question is the fibula, one of two bones inside the leg. In normal birds, the fibula stops about halfway down the leg, connected at the top but not the bottom, leaving it just hanging in space.
