A groundbreaking discovery has shed light on the genetic health of woolly rhinos just before their extinction. A genome reconstructed from a piece of flesh found in the stomach of a 14,400-year-old wolf pup suggests that these majestic creatures were thriving genetically despite facing a grim fate.
The wolf pup, part of the famous Tumat Puppies duo, was preserved in permafrost near Tumat, Russia. Analysis of its stomach contents revealed a fragment of woolly rhinoceros flesh, providing a rare glimpse into the diet of these ancient predators.
Lead researcher, Edana Lord from Stockholm University, described the discovery as unique and remarkable. The well-preserved tissue allowed scientists to reconstruct the woolly rhino’s genome, revealing a healthy female specimen with no signs of inbreeding.
Love Dalén, another team member, emphasized the significance of this find, stating that it challenges previous theories on the extinction of woolly rhinos. By comparing the newly reconstructed genome with older samples, the team concluded that genetic diversity and inbreeding levels remained stable, pointing towards climate change as the likely cause of their demise.
This study marks a milestone in ancient DNA research, showcasing the power of genetic analysis in unraveling mysteries of the past. The woolly rhino, once an icon of the last glacial period, continues to fascinate and educate us about the challenges faced by species in a changing world.
