Dinosaur-like lower leg created on bird through molecular experiment

Any one that has eaten roasted chicken can account for the presence in the drumstick (lower leg) of a long, spine-like bone. This is actually the fibula, one of the two long bones of the lower leg (the outer one). In dinosaurs, which are the ancestors of birds, this bone is tube-shaped and reaches all the way down to the ankle. Researchers have found that when a maturation gene called Indian Hedgehog was inhibited, this resulted in chickens that kept a tubular fibula as long as the tibia and connected to the ankle, just like a dinosaur.
