It's a question that has been debated by scientists for years: why is it so difficult to extract DNA from dinosaur fossils? Some say that the proteins and DNA molecules simply degrade over time, while others believe that the elements present in the fossilized bone matrix are too complex for DNA to escape. Whatever the reason may be, researchers have been struggling unsuccessfully to sequence dinosaur DNA since the 1990s. But now, a new study has finally cracked the code, and scientists may be...
