The tusk belonged to a woolly mammoth later named Élmayųujey’eh or, for short, Elma. Karen Spaleta, one of the new study's coauthors, takes a sample from a mammoth tusk found at Alaska's Swan Point archaeological site. Woolly mammoth tusks grew at a consistent daily rate, with the earliest days of the animal’s life recorded in the tip of the tusks. “The US Geological Survey has done a pretty darn good job mapping rocks in Alaska,” Rowe said. Changing the picture of hunter-gatherersThe new evidence advances more than an understanding of the early relationship between woolly mammoths and humans.

NEW YORK — Scientists discovered the oldest known DNA and used it to reveal what life was like 2 million years ago in the northern tip of Greenland. With animal fossils hard to come by, the researchers extracted environmental DNA, also known as eDNA, from soil samples. Studying really old DNA can be a challenge because the genetic material breaks down over time, leaving scientists with only tiny fragments. In their study, published Wednesday in the journal Nature, they compared the DNA to that of different species, looking for matches. He worked on the study that previously held the “oldest DNA” record, from a mammoth tooth around a million years old.
