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.
