NEW YORK (AP) — Scientists have discovered the oldest known DNA and used it to reveal what life was like 2 million years ago in the northern tip of Greenland. Today, it’s a barren Arctic desert. But back then it was a lush landscape of trees and vegetation with an array of animals, even the now extinct mastodon. The study published Wednesday looks at environmental DNA — bits of genetic material that organisms leave in their surroundings. By studying these tiny pieces, scientists found an unusual mix of species, with reindeer and geese perhaps living alongside mastodons.
