The local Tr’ondëk Hwëch’in First Nation discovered a creature named Zhùr by the people, in the Klondike Goldfields near Dawson City, in a gold mine that was destroying a wall of frozen mud in the water.
“This mummy is so complete, she is basically present in all her skin, most of her fur … all of her soft tissue, and she is 56,000 years old, or in her place,” anatomy at Decius University Julie Meuchen, an associate professor of science. In Iowa, told CNN.
The female puppy, according to Machen, “is the oldest, most complete wolf that has ever been found,” allowing researchers to deeply understand what her life looks like.
Using X-ray techniques, experts determined that the puppy, which Was preserved at permafrost, died at the age of 6 or 7 weeks.
Meanwhile, a technique called static isotope analysis revealed that the animals lived during a time when the glaciers fell again.
“There were not as many glaciers around, which meant there was a lot more fresh water,” she said. “There were too many streams, too many rivers flowing, and perhaps too many other animals. She lived in green time.”
Researchers found that the wolf cub’s diet was influenced by its proximity to water: isotope analysis revealed that “she and her mother were eating mostly aquatic resources – things like salmon, maybe some shore birds,” Meichen said.
A DNA analysis revealed that the puppy is descended from ancient wolves – the ancestors of modern wolves – from Russia, Siberia and Alaska.
“It’s not surprising – he deals with the things of the time,” she explained. “But the good thing about that, which most people would not know, is that the wolves in the Ice Age were only remotely related to the wolves that are around today.
“They are still the same species, but they are very different. Being in the same species. Their genetics have changed considerably over time – the diversity of wolves has diminished over time, and expanded again. is.
“He was actually an ancient wolf, and he was related to all the wolves around him at the time,” Machen said.
A pumafrost takes under very specific circumstances to make mummies, the researchers said, although many well-preserved wolf cubs have been reclaimed from Siberia. However, this cub was particularly rare in North America.
“It is rare to find these mummies in the Yukon. The animal has to die at a permafrost location, where the ground remains frozen all the time, and they have to be buried very quickly, like any other fossilization process,” Yuken said. Statement. “If it stays on the frozen tundra for too long, it will rot or eat.”
Because of his “pristine” condition, experts believe the wolf cub died immediately, perhaps when his den fell, as data showed he was not hungry.
The research was published on Monday in the journal Current Biology.
