An Extinct Cave Bear s DNA Was Still Readable After 360,000 Years

A tiny ear bone belonging to a cave bear that died some 360,000 years ago has yielded the oldest genome not sourced from permafrost. The newly sequenced genome is offering new insights into the evolution of cave bears and how climate change can precipitate the emergence of entirely new species.

“With DNA, we can decipher the genetic code of extinct animals long after they’ve gone, but over thousands of years, the DNA present in ancient samples slowly disappears, creating a time limit of how far back in time you can normally go,” Axel Barlow, the first author of the new study and paleogeneticist from Nottingham Trent University, said in a statement.

[FOR IMMEDIATE RELASE] San Diego, CA February 23, 2021 Publisher, Crytivo alongside the development team, Soda Den are excited to announce the release of their kickstarter trailer featuring never-before-seen footage of Roots of Pacha, a life-simulator set in the stone age.
What the Roots of Pacha Team calls the “Festival of Kickstarter” starts today with the launch of their brand new trailer and their Kickstarter campaign. The team has been revealing new animals, NPCs, and datable Clan members in the lead-up to the event.
Just days ago, I wrote an article about how the world’s oldest DNA was recovered from mammoths that lived more than a million years ago. The DNA was collected from three ancient mammoths that were preserved in the Siberian permafrost.
And now, new research has revealed that the oldest DNA from an animal not preserved in permafrost has been extracted from an ancient cave bear. The DNA was extracted from a large and vegetarian 360,000-year-old cave bear that lived in what is now Georgia during the Middle Pleistocene Period.
The cave bears’ scientific name is
Ursus kudarensis praekudarensis and they were known to hibernate in caves during the winter months. They weighed as much as a tonne (over double the size of a male polar bear) despite only eating plants and since they had a hard time storing fat away for their hibernation periods, they occasionally died during the winter months.
