In a monumental breakthrough, Danish scientists have revealed the discovery of the oldest DNA ever recovered, dating back approximately 2.4 million years. This groundbreaking revelation, published in Nature on December 7, surpasses the age of the previously oldest DNA found in a Siberian mammoth bone. The recovery of ancient DNA fragments from an ice sheet in northern Greenland not only opens a window into the distant past but also challenges existing paradigms about prehistoric ecosystems.
