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...

Many large charismatic mammals went extinct at the end of the Ice Age (approx 11,000 years ago), including the Steppe bison, Bison priscus. A recent find in Eastern Siberia has uncovered one of these bison, literally, frozen in time. The most complete frozen mummy of the Steppe bison yet known, dated to 9,300 years before present, was recently uncovered in the Yana-Indigirka Lowland and a necropsy was performed to learn about how this animal lived and died at the end of the Ice Age. The Yukagir bison mummy, as it is named, has a complete brain, heart, blood vessels and...
