DNA half-life only 521 years, so is dino DNA and insect amber DNA young?
If paleontology lives by radiometric dating, it also dies by radiometric dating. Either DNA trapped in 200 million-year-old Jurassic insect amber is young or it has some unexplained source. I argue it is young. Radiometric C-14 dates of fossils say the fossils are young. As I’ve said many times, the radiometric date of 65 million-year-old rocks is irrelevant to the radiometric date of the actual physical tissue of a fossil. I could bury a living dog in 65 million-year-old rocks, and the age of rocks will have nothing to say of the age of the dog. The best inferences for time of death of a fossil: half-life of C-14, half life of DNA, half-life of amino acids, etc., NOT the Read More ›
