Biologist have long stated that modern birds evolved from dinosaurs, and that they shared the same common ancestor as alligators. Now we have proof.
As strange as the above sounds, scientists have discovered that chickens had leftover dinosaur DNA to grow alligator-like teeth. Using a virus to deliver a genetic mutation that turns on the ancient DNA scientists were able growing these teeth in chickens.
*Unfortunately the picture above is not real, we cannot (yet) make dinosaur-chickens.
