Million-year-old DNA from mammoth teeth found in Siberia is oldest genome ever sequenced Posted WedWednesday 17 updated WedWednesday 17 FebFebruary 2021 at 9:46pm Space to play or pause, M to mute, left and right arrows to seek, up and down arrows for volume. Watch 1 s The ancient DNA, which came from the teeth of mammoths that once walked Siberia, is the oldest ever to be reconstructed. Share Print text only Cancel It s not quite Jurassic Park, but scientists have successfully extracted and reconstructed million-year-old DNA from mammoth teeth and solved a couple of mysteries about the creatures evolutionary history along the way. Key points: ....
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. Advertisement 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 ....
Beth Zaiken/Centre for Palaeogenetics For the first time, preserved DNA has been recovered from animal remains over a million years old. The DNA belonged to two mammoths that lived around 1.2 million years ago. The genetic sequences change our understanding of mammoth evolution. They reveal that, at that time, Siberia was home to two distinct groups of these animals. The mammoths of North America were the product of a hybridisation event between these two groups, and obtained half of their DNA from each. Advertisement “Instead of there being one species [or lineage] of mammoth up in Siberia around 1-2 million years ago, it now looks like there are two,” says Love Dalén at the Centre for Palaeogenetics in Stockholm, Sweden. ....
