European researchers have achieved a milestone in paleogenomics by sequencing RNA from a woolly mammoth specimen dating back approximately 39,000 to 40,000 years, roughly three times older than the previous record for ancient RNA. The RNA was recovered from a well-preserved juvenile mammoth known as Yuka, discovered in northern Siberian permafrost in 2010, according to Love Dalén, a professor of evolutionary genomics at Stockholm University and lead author of a study published in the journal Cell. Dalén told the Wall Street Journal that the findings could aid in identifying the genetic traits responsible for the mammoth’s distinctive woolly coat. The...

The unmistakable work of prehistoric humans was found etched into the mammoth's hide. Yuka the mammoth may have been killed by cave lions. Image credit: Zhuravlev Andrey/Shutterstock.com Often hailed as the best-preserved woolly mammoth corpse ever discovered, the body of a young female specimen named Yuka has just yielded a staggering surprise. By analyzing cut marks on the animal's hide, researchers have now determined that the beast was butchered by humans 39,000 years ago, thus providing the earliest evidence for the presence of people in the Arctic. Discovered in 2010 in the extreme north of Siberia, Yuka is thought to...
