How old is the oldest intact DNA? DNA fragments are known from bone fragments from the Mesozoic, but these don't count. I'm guessing the oldest DNA is recovered from permafrost, but how old exactly?
Well, the **_oldest intact DNA_** found is actually **419 million** years old, and it belongs to (not surprisingly) bacteria. Samples were extracted from surface-sterilized salt of different geological ages (23, 121, 419 million years of age, MYA). But as you mentioned, these are fragments. Studies ...
