Dino-chicken By: Will, John, Nicole and Nick Back in the day… • Mesozoic era • Dinosaurs were dominant life forms on planet Earth • Divided into two categories Ornischian • Bird hipped dinosaurs Saurishian • Lizard hipped dinosaurs First I was like • Therapod dinosaurs were bi-pedal carnivores • Ranged in size from three feet long to over forty • Only branch of dinosaurs to survive the KT extinction But then I was like! • Birds are the closest living relatives of therapod dinosaurs • All evolved wings over 65 million years • But all birds still share anatomical similarities with them • This is a chicken when it is still a developing embryo • Notice the long tail and exaggerated features • As an embryo chickens still have long tails, long clawed arms and legs, and even teeth • Video 1 There's no going back….or is there? • Scientists think they can genetically alter chickens back into dinosaurs • By somehow overpowering the recessive traits that control the chickens growth, vestigial traits can be left to develop Let there be DINO-CHICKENS • If these vestigial traits develop fully, chickens will be born resembling therapod dinosaurs • How awesome is that But how does this work? • The science is called Evolutionary Development Biology • Retinoic acid and tungsten wire used to try and promote tail growth Injecting chicken embryo at different points + times to affect development Video 2 Fossil cloning • Scientists have always pondered the idea of cloning dinosaurs through fossils • But there are several problems with this • Fossilization usually destroys all organic matter But wait! What about that one time? • In 2005 a fossilized phemur of a Tyrannosaurus containing “soft matter” was discovered in eastern Montana • The soft matter was hypothesized to be intact bone-marrow • Turned out to be too damaged to work with Aww man… • O well, but if the bone marrow was intact the scientists could use it • They would most likely 1.Take the nucleus out of a birds egg 2.Insert the nucleus of the T-rex’s bone marrow cell 3.Insert the egg into a lucky lady chicken Is it ethical? • There is some debate as to if this experiment is ethical or not • Ethics aside, Dino-chicken is not far off The End
