Scientists say they have recovered the oldest DNA on record, extracting it from the molars of mammoths that roamed northeastern Siberia up to 1.2 million years ago in research that broadens the horizons for understanding extinct species.
Scientists have successfully identified, extracted and analysed the oldest ever DNA from an animal which was not frozen and preserved in permafrost. The 360,000-year-old genetic material came from the bone of a cave bear, the larger and vegetarian relative of polar and brown bears, which died in what is now Georgia during the Middle Pleistocene. Analysis of its DNA reveals cave bears evolved 1.5 million years ago from the same common ancestor as brown and polar bears, as well as other now-extinct species.

Researchers just sequenced the world's oldest known DNA, which came from mammoth teeth found in the Siberian permafrost.
Teeth from mammoths buried in the Siberian permafrost for more than a million years have yielded the world's oldest DNA ever sequenced, according to a new study.
Scientists Have Sequenced Mammoth DNA That's Over a Million Years Old 17 FEBRUARY 2021 In a feat right at the limits of our scientific capabilities, an international team of geneticists has recovered and sequenced the oldest DNA to date. From the teeth of three ancient mammoths that roamed Siberia between 700,000 and 1.2 million years ago, the researchers extracted extremely degraded DNA, and pieced it back together to reveal a previously unknown genetic mammoth lineage. Previously, the oldest recovered DNA sample was from a horse bone found in the Yukon permafrost, dating back to betwee...
