DNA can't be recovered from dinosaurs

Dinosaur cloning might never be possible as DNA is found to have a half-life of only 521 years.

For a long time researchers have been investigating the possibility of recovering the DNA of a dinosaur, a concept used in the Jurassic Park film series to clone the creatures and bring them back to life. Now however it seems that this may never be possible at all because the half-life of DNA is too short for any to have survived since the last dinosaurs died out 65 million years ago. The research indicated that any preserved DNA is likely to become unusable after only 1.5 million years at most.

"This confirms the widely held suspicion that claims of DNA from dinosaurs and ancient insects trapped in amber are incorrect," said evolutionary biologist Simon Ho. "We might be able to break the record for the oldest authentic DNA sequence, which currently stands at about half a million years."

"By comparing the specimens' ages and degrees of DNA degradation, the researchers calculated that DNA has a half-life of 521 years."

Yeah...this is the sad truth. Many animals are killed off by humans. Dinosaurs would be no different.

It probably just as well. It is unlikely that any dinosaur could survive in the modern world. The O[sub]2[/sub] content is different, the temperatures and climate is different, their normal food sources are gone, the air and water are polluted, and they would have no resistance to modern diseases. Without being kept in a controlled, sterile environment, they would most likely not even survive the juvenile stage.

Somehow I get the feeling that creationist will see this as proof of a young earth as they have found dino dna. So we cant bring back the dinosaurs, that doesnt mean we cant try to save some species of animal that are on the brink of extinction or have recently gone extinct from sufficient samples of dna.

Mammoths are the most important animal to clone. The food and clothing they would provide would be critical for cold countries.

Seems like a big expense for something that sheep already provide... And according to some people on UM the world is full of sheep.
