Scientist grow a dinosaur leg on a CHICKEN in 'reverse evolution' experiment

Scientists in Chile have figured out a way to resurrect the prehistoric traits of dinosaurs.

In a ‘reverse evolution’ experiment, a researcher has manipulated the genes of modern chickens to induce the legs of a dinosaur.

These ancestors of birds once had a tube-shaped fibula that stretched down to the ankle. Through evolution, this transformed to become the short, splinter-like fibula of birds today.

The fibula is the outer bone in the lower leg, which has evolved in birds to be shorter than its neighbour, the tibia, and no longer connects to the ankle.

In the embryonic stage, it’s been previously noted that birds first develop a tubular fibula like that seen in dinosaurs.

As it develops, this bone becomes splinter-like and the tibia grows past it.

To understand this transformation, Brazilian researcher Joâo Botelho reversed the evolutionary process.

Normally, the shaft of the bone matures more quickly than the ends, ceasing cell division first.
