Researchers just sequenced the world's oldest known DNA, which came from mammoth teeth found in the Siberian permafrost.

DNA from teeth found in Siberia permafrost the oldest yet sequenced, pushing science into ‘deep time’

An international team led by researchers at the Centre for Palaeogenetics in Stockholm has sequenced DNA recovered from mammoth remains that are up to 1.2 million years old. The analyses show that the Columbian mammoth that inhabited North America during the last ice age was a hybrid between the woolly mammoth and a previously unknown genetic lineage of mammoth. The study provides new insights into when and how fast mammoths became adapted to cold climate.

Oldest sequenced DNA belonged to 1 million-year-old mystery mammoth Laura Geggel © Provided by Live Science An illustration of the steppe mammoths that preceded the woolly mammoth, based on the genetic knowledge from the Adycha mammoth. The oldest DNA ever decoded belonged to a mammoth from a mysterious, previously unknown lineage that lived about 1.2 million years ago, a new study finds.  Previously, the oldest known sequenced genome came from a horse that lived up to 780,000 years ago, in what is now Canada's Yukon Territory. Now, the mammoth discovery, "is, with a wide ...

Million-Year-Old Mammoth Teeth Contain Oldest DNA Ever Found A woolly mammoth tusk discovered in a creek bed on Wrangel Island in 2017.

This research, published today in Nature, not only provides exciting new insight into mammoth evolutionary history, it reveals an entirely unknown lineage of ancient mammoth.
