It's the oldest DNA we've ever been able to analyze, [*MIT Technology Review* reports](), with the previous record set last year when scientists recovered partial genomes from a [one-million-year-old Siberian mammoth](). The genetic material was collected from ancient sediment in Greenland, an area of the world that once harbored a far warmer climate that allowed a rich ecosystem of flora and fauna to flourish. Some of the samples were taken from a 300-feet-thick deposit of clay and sand back in 2006 and stored in a freezer in Copenhagen. The findings could give us clues as to how the local Greenland ecosystem was able to adapt to warming climates over the last two million years — and how current plant species may be able to adjust to a climate that's now warming even more rapidly. "It's a climate similar to what we expect to face on Earth due to global warming," the University of Copenhagen's Eske Willerslev, senior author of a [new paper]() about the project published in the journal *Nature*, told *MIT Tech*, "and it gives us some idea how nature can respond to increasing temperatures." The fragments paint a fascinating picture of what Greenland may have looked like millions of years ago. "It feels almost magical to be able to infer such a complete picture of an ancient ecosystem from tiny fragments of preserved DNA," University of California, Santa Cruz paleogeneticist Beth Shapiro [told the *New York Times*](). The recovered DNA includes fragments from flowering plants and trees, species that haven't been spotted in the area in a long time. "This is an ecosystem with no modern analogue," Willerslev told *MIT Tech*. "It’s a mixture between arctic species and temperate species." The fact that DNA remains of a mastodon, an ancient and long extinct relative of the elephant, were found in the area surprised scientists. "Not in a million years would you expect a mastodon up there," Love Dalén, a paleontologist at the Swedish Museum of Natural History, who was not involved in the study, [told *Nature*](). Samples from reindeer also proved surprising. "Reindeers, according to paleontologists, should not have survived; they shouldn’t even exist at that time," Willerslev told *Nature*. The samples were only recoverable thanks to freezing temperatures and the fact that they were bound to clay and quartz, slowing down DNA degradation significantly. In short, it's a tremendous achievement of modern science, enabled by cutting-edge gene sequencing technologies and providing an exceedingly rare snapshot into our planet's distant past — and perhaps a glimpse of our future as well. **READ MORE:** [DNA that was frozen for 2 million years has been sequenced]() \[*MIT Technology Review*\] **More on ancient DNA:** *[Billionaire Private Astronaut Suggests Reviving Dinosaurs]()* ## Author I've been at Futurism since 2017, where my role has evolved to encompass design, writing, and increasingly editing. I've always been fascinated by space exploration and advanced transportation, which I've leaned into by interviewing luminaries in those fields while closely following the dimensions of policy and regulation that allow next-generation projects to succeed -- or, sometimes, to fail. I'm also keenly interested in the effects of generative AI on society, policies, and democratic institutions, as well as clean energy, physics and biology, and the vagaries of tech leadership. My work for Futurism has been cited by publications including Ars Technica, Gizmodo, PC Magazine, Jalopnik, Fox News, and the New York Post. I spent my childhood living in locations including Manila, the Philippines, and Geneva, Switzerland, attended McGill University, and now live in Toronto, Canada. Before Futurism I worked at AskMen and a small photography studio. In my free time, I'm an avid gardener, foodie, and craft beer lover, as well as a maker of artisanal hot pepper sauces. I have a magnificent dog named Freida. ### Author social links [Bluesky]()
