Woolly rhinoceroses, which went extinct approximately 11,000 years ago, did not originate in high-latitude frozen regions as previously assumed based on comparisons with woolly mammoths. A new study combining ancient DNA analysis with habitat modeling spanning 500,000 years reveals that the genetic diversity of these Ice Age megafauna emerged through a different evolutionary pathway than their better-known mammoth contemporaries. This challenges the prevailing narrative about how these cold-adapted species evolved their distinctive features.
Why it matters
Understanding the true evolutionary history and habitat origins of extinct megafauna helps scientists better predict how modern species might adapt to climate change. This research demonstrates that species with similar cold-adapted features may have arrived at those adaptations through very different evolutionary routes, which has implications for conservation strategies.
Understand the Science
Woolly rhinoceroses (Coelodonta antiquitatis) were fascinating creatures: giant, lumbering Ice Age beasts with thick fur and massive horns that died out about 11,000 years ago. Previous genetic studies had left open the question of whether their genetic diversity emerged in high-latitude areas, like that of woolly mammoths, but a new analysis of ancient DNA and habitat models covering the past 500,000 years has revealed a different story.
