Young wolf corpses were intact after 14,300 years under permafrost

The hybrid wolf may be a prehistoric hunter's pet, retaining its fur thanks to its preservation of permafrost in Siberia.

Scientists successfully sequenced RNA from the body of a young Tan Tan wolf , found in the village of Tumat in the Sakha Republic or Yakutia four years ago. The team thinks that animals cross between dogs and wolves and are domestic pets. Its owner may be the ancient mammoth hunters. The results of the study are published in the journal PLOS Biology in early August.

Korean humanist Hwang Woo-suk and his colleagues carried out the cleaning of the mud and dirt covering the young wolf mummies for thousands of years on the Syalakh river. Hwang sought to sample cells to revive animals but failed. However, the team of Dr. Oliver Smith of the University of Copenhagen obtained results when analyzing RNA from liver, cartilage and muscle tissue of a prehistoric animal.

Sequencing RNA from liver tissue is representative of ARN of young wolves, many copies coincide with specimens from dogs and wolves today. The animal's transcription system is the oldest form of RNA ever sequenced, at least 13,000 years older than the second ancient transcription system.

"Previously, researchers were reluctant to arrange ancient RNA sequences because the molecule was less stable than DNA and often degenerated in enzymes. However, from recent success when the ancient ARN sequences were sequenced in plants. We speculate that the whole, frozen animal body under permafrost, may contain enough material to sequence, We are extremely happy to find RNA in different tissues of wolves. Young, " said Dr. Smith.
