LONDON: British scientists say they have pieced together what dinosaur DNA looks like. Researchers at the University of Kent say their work uncovers the genetic secret behind why dinosaurs came in such a variety of shapes and sizes. This variation helped the creatures evolve quickly in response to a changing environment — helping them to dominate Earth for 180 million years. But the researchers behind the DNA work say they have no plans to recreate dinosaurs, Jurassic Park style. Of course, there was one final challenge the dinosaurs could not overcome — a massive asteroid impact 66 million years ago that wiped out all dinosaur groups except the flying ones that developed into birds. — ONA
