2 Million-Year-Old DNA, the Oldest Ever Recovered, Opens Window to the Past

The prehistoric forest of northern Greenland was home to mastodons, reindeer, hares and an abundance of plant life.

As early as 2006, Eske Willerslev and members of his lab ventured into northern Greenland with a drill, extracting cores of sediment from the Kap København Formation. They were hunting for environmental DNA, or eDNA, in their cores — puzzle pieces that could help paint a picture of the plants and animals present in the region 2 million years ago.

But for the longest time, they came up empty-handed. “Every time we had improvements in terms of DNA extraction or sequencing technology, we’d revisit these samples,” Willerslev, an evolutionary geneticist at the University of Cambridge, said in a press briefing on Tuesday.

No matter what, the researchers failed to get what they were looking for. The run of bad luck saw members of the lab turn to the occult for an explanation; they named their troubles “the curse of the Kap København Formation.”

But with steady improvements in DNA extraction and sequencing technologies, the curse was finally broken.

On Wednesday, the team published the results of their 16-year pursuit of ancient DNA in the journal Nature. They were able to sequence eDNA from 41 sediment samples, collected in 2006, 2012 and 2016 from the Kap København Formation and undisturbed by humans for 2 million years. Their analyses revealed that a lush forest replete with reindeer, hares, mastodons and a wide variety of flora once stood in what is now a dull, gray polar desert.

Willerslev, a pioneering geneticist who has previously recovered eDNA from ice cores and shown it could survive in glaciers, noted that the “breakthrough” relied on expertise, advances in genetic sequencing techniques and bioinformatics.

History in the soil

DNA, which carries the instructions for life, is not a particularly sturdy molecule. The bonds that hold it together are weak and, over time, they break down.

This is why, even though we have an abundance of dinosaur fossils, we don’t have any dinosaur DNA. The beasts died out 66 million years ago, and the DNA would simply not survive that long.

When DNA degrades, the once-long strands of information break apart into smaller and smaller pieces. It becomes almost impossible to piece these fragments back together in the right configuration, especially if they are mixed in with a lot of other DNA from the environment.

Think of DNA like a book. Let’s say Alice in Wonderland. If you have the whole book, you can understand the story. But if you’re missing a few pages, you might not understand where the White Rabbit came from or why Alice ended up at a tea party with the Mad Hatter. If you’re missing lots of pages, you probably can’t even tell what the story was to begin with. Alice? Who’s that? And why is she 10 feet tall?

That’s the problem working with ancient DNA. You might be able to retrieve small fragments of DNA but it is generally too fragmented to be able to tell where it came from — and certainly too fragmented to understand where it came from.

But under certain circumstances, DNA fragments can survive deep time.

“The ‘survival time’ of DNA in the environment is incredibly variable and strongly dependent on the environment itself,” notes Michael Knapp, an ecologist and geneticist at Otago University in New Zealand.

Previously, the oldest DNA ever recovered came from mammoth fossils found in the Siberian permafrost. In a Nature paper in 2021, researchers showed that DNA from the mammoth teeth was, potentially, about 1.6 million years old. The DNA recovered was broken up into small fragments but they weren’t degraded so much they couldn’t be pieced back together. The cold temperature of the permafrost certainly helped with this.

It’s a similar story in the new study.

Willerslev and his collaborators postulate that the long survival time of the DNA in their sediment cores was possible for two reasons. The first is the constant cold temperature of the polar desert. The second is the way the DNA is bound to minerals in the cores, preventing degradation over longer time scales. The idea is that these mineral surfaces prevent enzymes from breaking down the DNA.

Karina Sand, a geochemist at the University of Copenhagen and co-author on the paper, explained that one of the technological leaps that enabled this feat was extracting DNA from clay and quartz minerals. The latter provided an abundance of DNA, but the former was harder to extract good DNA from. Fortunately, that leaves the door open for even older DNA extraction.

“If we can get better at extracting the DNA from the clay minerals, then we think we can go further back in time with DNA,” she said.

The research team was able to extract DNA from the sediment cores and begin to read the surviving fragments. These fragments were then compared to a database of genomes (complete DNA sequences) of modern plants and animals, looking for DNA matches. Over time, they were able to fill the blank pages of history, demonstrating the thriving ecosystem of ancient Greenland.

The ancient forest of Greenland

Two million years ago, Greenland was a different place.

“The Kap København ecosystem, which has no present-day equivalent, existed at considerably higher temperatures than we have today,” noted Mikkel Pederson, a geneticist at the Lundbeck Foundation GeoGenetics Centre, in a press release.

In northern Greenland, average temperatures during this time were likely more than 11 degrees Celsius (around 20 degrees Fahrenheit) higher than they are today. Previous studies at Kap København have shown evidence it was home to a boreal forest, but the eDNA extracted and analyzed in the new study provides a complete reimagining of the area, adding in megafauna and a wide variety of plant life.

The headline mammal DNA found in the cores is undoubtedly the mastodon — which is having a bit of a moment thanks to social media. Some of the eDNA found matched to the Elephantidae family, which includes elephants, mammoths and mastodons. It seems mastodons may have roamed Greenland 2 million years ago, though the researchers note the evidence isn’t extremely strong and is based on relatively weak DNA matches.

The team also found DNA related to reindeer, hares and rabbits, and the subfamily of animals that includes lemmings, voles and muskrats. Notably absent, however, is DNA from carnivores. The researchers suggest this is because of their comparably small biomass in relation to the herbivores. “It’s basically a numbers game,” Willerslev said.

One of the more intriguing DNA finds is of the Atlantic horseshoe crab. The species is no longer found at such northern latitudes, and the authors suggest this may mean Kap København experienced warmer sea surface temperatures 2 million years ago. Previous research has suggested the sea surface was warmer at higher latitudes, and the discovery of horseshoe crab DNA lends further support to this hypothesis.

Warmer temperatures are key. Multiple authors on the paper have reiterated the importance of understanding an ecosystem like this, given the effects of global warming. Two million years ago, the climate was changing and the eDNA shows that Arctic species were living with species that loved much warmer climes. This helps scientists to get an understanding of how nature was adapting to those changes and, within the DNA signatures, there may be clues to ways we could help modern-day fauna and flora survive extreme climatic swings.

One of the significant limitations of studying eDNA is that scientists have to postulate about the kinds of species that were living at the time. Knapp notes closely related ancient species might give you a DNA match but this is “somewhat inaccurate” — it provides an approximation of what existed. We may only be able to assign the DNA at a family or order level, so we can’t know exactly what roamed the boreal forest of Greenland 2 million years ago.

Even so, the recovery of DNA this old opens a new window to the prehistoric Earth, a pathway for scientists and researchers to probe the ecosystems that existed long before humans were around. The team will head to northern Canada to extract cores next year and hope to go even further back in time.

The extraction method may even lend itself to finding DNA in more humid climates across the world, like in Africa and Australia.

“If we can begin to explore ancient DNA in clay grains from Africa, we may be able to gather ground-breaking information about the origin of many different species —perhaps even new knowledge about the first humans and their ancestors,” Willerslev said in a statement.

“The possibilities are endless.”

Kremlin Confirms Putin Transmitted Iran’s War Resolution Plan to Trump

The Kremlin says Putin relayed Iran’s proposal for ending the war to Trump, while Trump announced a Russian diesel supply deal that drew sharp criticism from Zelenskyy.

Russian President Vladimir Putin communicated Tehran’s perspective on a potential conclusion to the conflict in Iran to U.S. President Donald Trump, according to Russian state media reports on Saturday.

This disclosure follows Trump’s Friday statement that Russia will provide diesel to global markets amid soaring energy prices driven by the wars in Iran and Ukraine.

Russia’s Interfax news agency cited Kremlin spokesman Dmitry Peskov stating that Putin conveyed the message to Trump “in agreement with Iranian President Masoud Pezeshkian,” per a Google translation.

Additional Russian media accounts indicate Putin spoke with Trump by phone after meeting Pezeshkian on the margins of a summit in Turkmenistan.

Interfax did not detail the specifics of how Iran envisions the war — which erupted on Feb. 28 with U.S. and Israeli airstrikes on Iranian targets — reaching an end.

The White House did not immediately respond to Verum’s emailed request to confirm the reported conversation between Putin and Trump.

Russia supply deal

Trump announced Friday that Russia will deliver more than 4 million tons of diesel to the global market under an arrangement he said he agreed with Putin during a phone call.

Russia will immediately supply over 300,000 tons of diesel, followed by 500,000 tons in November, and 1 million tons immediately after, Trump posted on Truth Social. Moscow will then provide another 3 million tons of diesel contingent on the condition of Russia’s refineries, Trump added.

The Treasury Department temporarily waived sanctions on Russian diesel through April 2027 under a general license issued Friday.

Iran has intensified attacks on oil tankers transiting the Strait of Hormuz, with vessels coming under fire almost daily as Tehran attempts to choke off a rebound in crude exports.

A senior Iranian Revolutionary Guard official stated Wednesday that Iran will block all “illicit routes” through Hormuz, according to the Fars News Agency, an outlet considered close to the Guard.

The surge in tanker attacks coincides with crude oil exports from the Middle East rebounding in September to prewar levels, largely because the U.S. military escorted ships through Hormuz along Oman’s coast.

An interim agreement signed in June between the U.S. and Iran to pause hostilities to allow for negotiations quickly collapsed.

‘Gifts to Putin’

Ukrainian President Volodymyr Zelenskyy immediately denounced Trump’s diesel deal with Putin. Ukraine’s leader warned that easing sanctions without a commitment from Russia to de-escalate the war will only prolong it.

“Gifts to Putin will not bring peace or any benefit to the civilized world,” Zelenskyy said in a social media post. “Russia will ‘repay’ the diesel with further terror and perfidy. Allowing Russia to sell petroleum products is an investment in a war that must be ended, not prolonged.”

Diesel prices have surged worldwide as Ukraine has pounded Russian refineries, forcing Moscow to ban diesel exports to global markets. Iran and its Houthi allies have also attacked refineries in the Middle East, further constraining fuel supplies.

Trump faces mounting political pressure to lower fuel prices ahead of the November midterm elections. Republicans confront competitive races in conservative strongholds like Iowa, where farmers feel the pinch of high diesel prices.

AI is Changing How Lawyers Work — and Putting the Billable Hour Under Pressure

AI is reshaping the legal industry by reducing the time needed for routine tasks, challenging the traditional billable hour model, and changing how lawyers learn and practice.

Artificial intelligence is now used by almost 90% of legal professionals in the U.K. and Ireland, and it’s putting one of the profession’s oldest conventions — the billable hour — under the microscope. That’s according to legal software company Clio’s U.K. & Ireland Legal Insights Report 2026.

It found that among firms using AI, almost 80% said they can handle more work without increasing resources, while over 70% said it cut costs by absorbing administrative work once done by support staff.

As a result, AI is challenging some of the assumptions on which the legal profession was built, forcing firms to reevaluate how their lawyers spend their time, how they charge for it and how new lawyers learn the ropes. You can’t charge 16 hours for something that takes 16 secondsNick Rowles-DaviesLexolent Some of the U.K.’s biggest firms are already putting this into practice.

A&O Shearman has worked with legal AI company Harvey to develop artificial intelligence agents for tasks, including reviewing loan agreements and analyzing regulatory filings, which it says can complete in minutes work that previously took several hours. Slaughter and May, meanwhile, has rolled out Harvey across all practice areas this year, including for regulatory research and document analysis.

Billable hour pressure The billable hour is central to the business model of many law firms, but when AI significantly reduces the time lawyers spend sifting through and drafting documents, the economics are no longer so straightforward. “You can’t charge 16 hours for something that takes 16 seconds,” Nick Rowles-Davies, founder and CEO of legal finance fund Lexolent, based in London and Dubai, told CNBC.

About one in five firms that have widely adopted AI report difficulty meeting billable-hour targets, according to Clio’s report. Globally, senior legal leaders expect the share of work charged by the hour to fall from 72% to 44% over the next two to three years, according to a Deloitte survey.

Routine work is the most exposed, Rowles-Davies said. “If you’ve got standard documents and you’re just putting in detail, then clearly that’s an automatic process.” But complex legal work still requires human judgment, he added, particularly when interpreting AI output and determining the right strategy for a client.

AI and workloads

Whether AI efficiencies ultimately make lawyers’ working lives better may depend on what firms do with the time they get back. Clio’s report found that 51% of legal professionals work evenings, but only 32% want to, while 22% work weekends compared with 11% who would choose to.

Joshua Lenon, Clio’s New York-based lawyer-in-residence, believes some lawyers are already seeing the benefits. “Lawyers [are] telling us that their day is getting better,” Lenon told CNBC, as AI becomes more commonplace.

“People are really looking at these tools and saying, ‘This is making work better.’”

Trump’s diesel agreement with Putin accused of contradicting Russia sanctions law

Ukraine President Volodymyr Zelenskyy said in a searing statement that the U.S. easing sanctions on Moscow “plays into Russia’s hands.”

President Donald Trump’s Friday announcement that Russia will supply diesel fuel to the global market marked an apparent pivot from recent efforts to pressure Moscow to end the Ukraine war by targeting Russian energy exports.

Trump claimed the move, unveiled with less than a month left in an affordability-focused midterm election, would swiftly bring down record-high diesel prices.

But commentators and critics were quick to highlight contradictions between the new policy and prior efforts by the U.S. to clamp down on Russian oil sales.

Those efforts most recently included the enactment of the Lindsey O. Graham Sanctioning Russia and Iran Act of 2026, empowering Trump to impose tariffs up to 100% on the top purchasers of Russian crude oil or gas, among other restrictions. Trump signed the bill into law just three weeks ago.

“Congress just passed a law giving Trump the power to impose new tariffs on major buyers of Russian oil & gas,” Scott Lincicome, vice president of the libertarian Cato Institute, said on X after Trump’s Friday announcement.

“Can America tariff America?” he quipped.

Sen. Richard Blumenthal, D-Conn., a member of the Senate Ukraine Caucus, accused Trump’s latest move of being “directly contrary to Congress’s intent in our bipartisan sanctions bill.”

Peter Harrell, visiting scholar at Georgetown University Law Center’s Institute of International Economic Law, in an X post said that the relaxation of Russian diesel restrictions “pretty much proves the point that the Graham Russia Bill was not going to force the Trump Administration to increase economic pressure on Moscow.”

Some of the criticism crossed party lines.

“Through the Lindsey O. Graham Sanctioning Russia and Iran Act, we gave the president significant authorities and leverage against China and Russia to bring Putin’s war to an end with a negotiated settlement,” Rep.

Michael McCaul, R-Texas, said in an X post. “Unfortunately, while I understand the desire to bring down diesel prices, I am concerned the lifting of sanctions on Russian oil will only fund the Kremlin’s war machine—emboldening more violence and destruction, as we have seen in recent days,” McCaul said.

The White House did not immediately respond to CNBC’s questions about the diesel agreement with Russia.

Less than a year earlier, the Trump administration slapped sanctions on multiple Russian oil companies in response to what it called “Russia’s lack of serious commitment to a peace process to end the war in Ukraine.”

Trump also had previously slammed NATO allies for continuing to buy Russian oil. In a September 2025 Truth Social post, he wrote, “the purchase of Russian Oil, by some, has been shocking! It greatly weakens your negotiating position, and bargaining power, over Russia.”

Later that month, Trump again harangued world leaders for doing business with Russia.

“They’re funding the war against themselves. Who the hell ever heard of that one?” he said in a speech at the United Nations General Assembly. “They can’t be doing what they’re doing. They’re buying oil and gas from Russia while they’re fighting Russia.”

Trump announced the diesel deal in a Truth Social post Friday afternoon after what he described as a “highly successful discussion” with Russian President Vladimir Putin.

Under the agreement, Russia will immediately supply more than 300,000 tons of diesel, then another 500,000 tons in November, followed by 1 million tons “immediately thereafter” and 3 million more depending on refinery conditions, Trump wrote.

The Treasury Department soon after said that Trump directed the Office of Foreign Assets Control to immediately issue a “temporary general license to allow the supply of Russian diesel to the global market.” OFAC specified that the sanctioned transactions will be authorized for about six months, until April 7.

Russia seemed to celebrate the move. “Russia-US cooperation on diesel and energy will benefit the world,” an X account associated with Putin’s economic envoy Kirill Dmitriev said in response to the announcement.

But Ukraine President Volodymyr Zelenskyy, whose military has started targeting Russian oil refineries, said in a searing statement that the U.S. easing sanctions on Moscow “plays into Russia’s hands.”

“Any easing of sanctions against Russia without a clear and lasting de-escalation agreement with Russia is an obvious weakness,” Zelenskyy said. “Allowing Russia to sell petroleum products is an investment in a war that must be ended, not prolonged.”

“We count on America’s fair support for our defense of life, for our defense of people in Ukraine – and on the United States having a correspondingly strong conversation with Russia,” he said.

“A strong one, not a weak one,” he added.

Trump thanked Putin later Friday afternoon for enabling “massive amounts of oil” to come to the U.S.

“We need oil for the world, and this is diesel, which is what we need, so we’re very happy to get it,” Trump told reporters before heading to Syracuse, New York.

The Trump administration has previously eased some Russian energy sanctions temporarily, though more narrowly than Friday’s announcement.

Earlier this year, in an attempt to stabilize markets after the start of the Iran war, the Trump administration issued limited, 30-day waivers allowing countries to buy sanctioned Russian oil that was already in transit.

But some interpreted the latest move as a more significant step.

“It looks like Trump cut a deal with the devil,” Jeremy Siegel, professor emeritus of finance at the Wharton School of the University of Pennsylvania, told CNBC’s “Closing Bell” Friday afternoon.

“It’s not a permanent solution at all. It’s sort of a short-term Band Aid,” Siegel said. “And cutting back on or eliminating sanctions on Russia for the invasion in Ukraine, I think, is a very unfortunate consequence.”
