The work extends the timeframe in which original molecules may preserve, and demonstrates the ability to distinguish between ancient microstructures in fossils. (sciencedaily.com)
The work adds to the growing body of evidence supporting persistence of original molecules over millions of years and also provides direct evidence that a pigment - based survival trait common to modern sea turtles evolved at least 54 million years ago. (sciencedaily.com)
That is not to say that TNA will dethrone RNA entirely as the original molecule of life. (newscientist.com)
