Scientists know what dinosaur DNA looked like - Unexplained Mysteries

Scientists know what dinosaur DNA looked like Posted on Monday, 27 August, 2018 | 7 comments Birds and dinosaurs still share remarkably similar DNA. Image Credit: CC BY 3.0 Nobu Tamura In a recent breakthrough, researchers in the UK have managed to piece together a history of dinosaur DNA. In the movie Jurassic Park, scientists use DNA preserved in amber to recreate living, breathing dinosaurs. In reality, however, achieving this is not quite so simple because over the course of millions of years, DNA inevitably breaks down, no matter how well it may have been preserved.Now though, researchers at the University of Kent have found a way to build up a picture of what dinosaur DNA might have actually been like. Their study focused on analyzing the DNA of the dinosaurs' living descendants - the birds - as well as other prehistoric reptiles such as turtles.By building up a history of DNA dating back 255 million years, they were able to discover that the DNA of today's birds is actually not that different to that of the dinosaurs themselves.This DNA, they argue, has been highly stable throughout history and the way it has been organized may have "provided a blueprint for evolutionary success" by generating variation and facilitating natural selection. This may also be why there is so much variation in the bird species we see today."The fossil evidence and now our evidence reinforces the idea that rather than birds and dinosaurs being distant relatives, they are one in the same," said Dr Rebecca O'Connor."The birds around us today are dinosaurs."Sadly though, the research is unlikely to lead to a real-life Jurassic Park anytime soon.

Yeah surely they are dinosaurs. #2 Posted by pallidin on 27 August, 2018, 17:41 Now I'm afraid of birds. Thanks. #3 Posted by pallidin on 27 August, 2018, 17:47 Ever see a ticked-off ostrich, uh, dino decendent? #4 Posted by Seti42 on 27 August, 2018, 23:55 Yep. Just look at this roadrunner I saw and photographed a few years ago right outside my local library. I see them all the time. They are awesome little dinosaurs. My cat is (rightly) afraid of them too. PS: Damn, your picture size requirements are terrible on this site...I had to shrink this A LOT to allow it to be posted here... 240KB or less?! It's 2018...Even the crappiest cell phone camera makes larger image files than that nowadays. #5 Posted by Antnanna on 28 August, 2018, 4:16 Nice pic #6 Posted by paperdyer on 28 August, 2018, 20:01 Yes, Nice pic. Did you see Wyle E. Coyote? I had gotten my Mom a mynah bird for a present. The bird talked, whistled and said some right things at the wrong time. My cat and dog had a habit of checking in on the bird. Well the cat got pecked on the tail since she liked to rub herself on the cage and the Brittany got pecked on the nose for her trouble. You may know, but mynah's are sloppy birds. They like taking baths and make a mess of their cage. The cages rust-out. Now what's supposed to happen in giving your mynah a new cage is to put his food and water in the new cage. open the do...

Eg birds today. I'm wondering actually weather scientist or able to determine our own evolution. Let me guess we are nowhere near the same age as the birds which can of course raise plenty of questions. Please Login or Register to post a comment. On the forums
