HOW LONG CAN ANCIENT DNA SURVIVE? “In theory, retrievable aDNA could survive for up to 1 million years under ideal conditions. In practice, however, the oldest recovered aDNA is from the early Middle Pleistocene epoch … (up to ~780,000 years old) and from sediment that originated below the Greenland ice sheet (up to ~800,000 years old).”
