Siberian puppy frozen 14,300 YEARS ago found 'perfect preserved' – and may have been a pet



A PUPPY frozen for 14,300 has been dug up in Siberia –

The exceptionally well-preserved mutt also was given a golden ticket to the past: the oldest 'working copies of genes'

The creature dates back around 14,000 years The ancient creature was first found in 2015, buried in permafrost in Tumat , Siberia.

It's believed to be a canid, possibly a wolf, or a domesticated wolf-like creature.

Now the pup has been analyzed by a team of experts, leading to an enormous scientific advance.

DNA can survive for thousands of years with the right conditions.

down because of recycling enzymes.

RNA is the working copy of a gene, which is hugely important.

While DNA reveals what G enes a creature had, and the RNA could tell which particular genes were working – and which were not active.

But in a rare feat, researchers were able to analyze RNA from the liver, cartilage and muscle tissue of the long-dead pooch.

"Ancient DNA researchers have previously been relied upon to test RNA as an RNA because it is generally more stable than DNA, and more prone to enzymatic degradation," said Dr Oliver Smith, of the University of Copenhagen, who published the study in PLOS Biology.

"However, in the sequencing of ancient RNA from plant material, we speculated that a well-preserved animal specimen was frozen in the permafrost

"To our delight, we did not find RNA from various tissues, but in some cases the signal was so strong that we could distinguish between tissues in a way that makes biological sense."

What is RNA? A simple explanation

It's different from DNA, in which it contains one single strand – rather than two intercoiled strands

  • It's also made
  • DNA is the core information that makes up a cell
  • But RNA is the active ingredient that does the work inside cells
  • All of the DNA has been found to be isolated on Earth
  • 19659059] Scientists think the creature may have been a pet.

  • In other news, the world's "oldest animal" was a fossilized 558million-year-old Russian fossil.

    And the world's oldest animal footprints reveal a strange burrowing creature that lived 550million years ago.
