The Big Question
So the big question, will dinosaurs ever evolve again? The last of them died out over 65 million years ago, meaning all dinosaur DNA has decayed and can no longer be used to mutate dinosaurs. It has never been known in the course of life history for an extinct animal to re-evolve, because the earth changes over time so quickly and dinosaurs could not exist in today's climate. They would most likely die from a disease right away because they would not be suited to our present day environment. Even if they do, it would be extremely difficult to adapt since the time gap is so distantly apart, and the world now is mostly dominated by mammals. However, it is said that scientists could essentially “design” the dinosaur genome, based on available knowledge about the evolutionary relationship between the extinct creatures and their winged descendants. Unfortunately, even if this was possible, it probably wouldn't be as simple as just taking apart and then reassembling the birds' DNA. The main challenge regarding this process would be in determining exactly what to change or adjust in birds’ genes to be able to reconstruct the dinosaur genome. With the earth so populated, there's barely any suitable areas or even natural resources for the dinosaurs to freely live in. In addition, recent research from a team based in West Australia revealed that DNA cannot survive for more than 6.3 million years, and of course, dinosaurs have been extinct for more than 65 million years.
