Ancient RNA Snapshot: A Woolly Mammoth’s Life 39,000 Years Ago
The remarkable discovery in Siberia In the frozen soils of present-day Siberia, a woolly mammoth named Yuka has become a time capsule from the late Pleistocene. When a mammoth dies and encases itself in permafrost, its tissues can be preserved for tens of thousands of years. Yuka’s remains—hair, muscle, and other soft tissues—have offered scientists…
