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 margin, the oldest DNA ever recovered, study senior researcher Love Dalén, a professor of evolutionary genetics at the Center for Palaeogenetics in Stockholm, said at a news conference Tuesday (Feb. 16).

An international team of scientists has sequenced DNA from mammoth teeth that is at least a million years old, if not older. 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.

Mammuthus primigenius) may rival
T. rex in popular imagination, but it is, in fact, one of the last mammoth species to have evolved, and it’s only one of various, sometimes odd-looking species of large, tusked animals belonging to the order Proboscidea. Mammoths are believed to have originated in Africa approximately 5 million years ago, with populations traveling north into what is now Eurasia and eventually moving into North America. We still have much to learn about these ancient proboscidean predecessor

Scientists have pushed technology to its limits after they managed to sequence the genome of a mammoth tooth that’s more than a million years old. Officially, this is the oldest DNA sequenced thus far by a long shot.
The million-year-old genome is finally upon us
In 2013, scientists sequenced the genome for the previous record-holder, DNA from a 780,000-year-old horse leg bone. Finding other similarly ancient genomes, however, is challenging work because DNA strands become increasingly small with time after an organism perishes. You need extraordinary circumstances to preserve DNA this old.

A tooth from a mammoth that roamed the Siberian steppe more than a million years ago has yielded the world s oldest DNA sequence.
It s the first time that DNA has been recovered from animal remains more than a million years old. Previously, the most ancient DNA sample was from a horse that lived between 560,000 and 780,000 years ago.
