If you've seen Jurassic Park, you probably remember the scene in which they were given A crash course in science will bring dinosaurs back to life via a video from the amusement park. The video featured a multi-colored cartoon called Mr. DNA explaining that it would take years for scientists to view DNA sequences. In fact, in 1
While bones in the earth can be preserved as fossils for millions of years, the DNA is not that hard and collapses much faster. Instead of extracting blood from mosquitoes into amber, the research team used modern avian and non-avian DNA and worked backwards to reconstruct what the dinosaur DNA looks like. The study published in Nature Communications suggests that dinosaurs, like dinosaurs, had a large number of chromosomes, which could explain why there were so many species. "We believe it creates variations," said Professor Darren Griffin of the BBC. "With so many chromosomes in existence, dinosaurs can rearrange their genes much more than other types of animals, meaning that dinosaurs can evolve faster and survive as long as the planet has changed." Dr. Rebecca O & # 39; Connor added that the new evidence supports the idea that birds and dinosaurs were not relatives, but in fact "one, the birds around us are dinosaurs today."
A Better Idea of What Dino Is DNA looks cool and is a big step forward, but it's not as cool as Mr. DNA, Griffin said. "We will not have Jurassic Park soon," he said, explaining, "If you take the DNA of a chicken and put it in an ostrich egg, you will not end up with a chicken or ostrich. You'll end up with nothing like the same result. the same goes for a Velociraptor or a T. rex, it just would not work. "
