New study challenges a site that’s key to how humans got to the Americas

NEW YORK (AP) — For decades, the strongest evidence for the earliest human settlement in the Americas came from a site in Chile called Monte Verde.

Scientists found echoes of human presence dating back to around 14,500 years ago, including footprints, wooden tools, foundations for a building and the remains of an ancient fire pit. They dated sediments and artifacts from the site to this time frame.

A new study challenges the age of this important site, suggesting Monte Verde might be much younger than scientists thought. But not everyone agrees with the findings.

Scientists sampled and dated sediments from nine areas along the Chinchihuapi Creek by the site and analyzed how the landscape changed over thousands of years. They uncovered a layer of volcanic ash from an eruption dating back to about 11,000 years ago.

Anything above that layer — in this case, the Monte Verde wood and artifacts — had to be younger, according to study co-author Claudio Latorre.

“We basically reinterpreted the geology of the site. And we came to the conclusion that the Monte Verde site cannot be older than 8,200 years before present,” said Latorre, who works at the Pontifical Catholic University of Chile.

The researchers think changes to the landscape, including a stream wearing down the rocks, may have mixed old layers with new, causing researchers to date ancient wood as part of the Monte Verde site.

The findings were published Thursday in the journal Science. Several scientists, including those involved with the original excavations, take issue with the results.

“They have provided, at best, a working hypothesis that is not supported by the data they presented,” said Michael Waters of Texas A&M University, who had no role in either study.

Experts not involved with the research say the study includes analysis of samples from the area surrounding Monte Verde, where the geology isn’t comparable to the site itself. And they say there’s not enough evidence that the layer of volcanic ash once covered the entire landscape.

They also say the study doesn’t offer a sufficient explanation for the artifacts found at the site that have been directly dated to 14,500 years ago, including a mastodon tusk fashioned into a tool, a wooden lance and a digging stick with a burned tip.

“This interpretation disregards a vast body of well-dated cultural evidence,” archaeologist Tom Dillehay of Vanderbilt University, who led the site’s first excavation, said in an email.

The new study’s authors disagree with these criticisms, saying they sampled within, upstream and downstream of the site. And there’s not enough evidence that the dated artifacts at the site really are that old, said co-author Todd Surovell, of the University of Wyoming.

The Monte Verde site is critical to scientists’ understanding of how people got to the Americas. Scientists used to think the first arrivals were a group of people 13,000 years ago who made tipped stone tools known as Clovis points. The discovery and dating of Monte Verde, which was initially mired in controversy, appeared to put that to rest.

It’s unclear how a new date for the site might affect the human story. Since Monte Verde, researchers have uncovered sites in North America that predate the Clovis people, such as Cooper’s Ferry in Idaho and the Debra L. Friedkin site in Texas.

But another big question is how, exactly, people got to the Americas from Asia, maneuvering south of two massive ice sheets covering Canada. Did humans arrive in time for the sheets to part, revealing an ice-free corridor? Did they travel along the coast in boats, or over a mix of water and land?

A revised date for Monte Verde could reopen discussions about the most likely route by early humans, said Surovell. Future independent analyses of other early human sites could provide more clarity.

“Given enough time and given the ability to do science, science is self-corrective,” Surovell said. “It eventually reaches the truth.”

China rebukes UK over nationalisation of British Steel

China rebukes UK over nationalisation of British Steel

The UK has appropriated its last working steelworks, following fears its former Chinese owners would shut it down.

Beijing has warned the United Kingdom that its nationalisation of British Steel has “severely undermined” Chinese companies’ confidence in investing in the UK.

The UK nationalised the loss-making company on Thursday in what the government said was a move taken to protect national interests.

British Steel is the only source of primary steelmaking in the UK. It supports approximately 2,700 jobs across its main steelworks in Scunthorpe and across the wider supply chain.

The company’s former owner, Jingye – which is among the 100 biggest companies in China – bought British Steel for 70 million pounds ($94m) in 2020. By 2025, Jingye said it was losing 700,000 pounds ($942,000) every day.

British Steel’s nationalisation has been in the works for more than a year.

In March 2025, Jingye carried out a consultation that concluded that the British Steel furnaces were not financially sustainable. The following month, it emerged that Jingye had cancelled orders for a key material used in the steelmaking process, stoking fears that it was planning to shut down the blast furnaces.

That month, the UK government seized operational control of British Steel from Jingye to stop that from happening. The Chinese company retained ownership, but lost operational control.

Thursday, though, saw ownership officially transfer to the UK government, which says it will appoint an independent valuer to “assess whether any compensation is payable” to Jingye.

The process has angered Beijing. The expropriation of British Steel “seriously damaged” Jingye’s legitimate rights and interests and “severely undermined” Chinese companies’ confidence in investing in the UK, China’s Ministry of Commerce said in a statement on Friday.

The UK, the ministry said, has “forcibly” taken over the company and “disregarded” Jingye’s contributions to the British economy and society.

The ministry urged the UK to fulfil obligations under the China-UK Investment Protection Agreement and said it would assist Chinese companies in protecting their rights.

Iran calls on Houthis to prepare to cut off Red Sea gateway — can the terror group do it?

Iran calls on Houthis to prepare to cut off Red Sea gateway — can the terror group do it?

NEWYou can now listen to Fox News articles!

Iran has reportedly instructed Yemen’s Houthi terrorists to prepare to close a critical Red Sea gateway if the United States attacks Iranian power infrastructure, Reuters reported, a threat experts warn could sharply disrupt global shipping even if the group cannot completely seal the waterway.

“This threat should be taken seriously,” Nadwa Al-Dawsari of the Middle East Institute told Fox News Digital. “With recent escalation and U.S. strikes on Iran, Tehran has already signaled that the Bab al-Mandab could become part of its response.”

Three sources told Reuters on Thursday that Iran’s leadership had discussed using the Houthis to shut the Bab el-Mandeb Strait and recently conveyed the request to the group. A source close to the Houthis said missiles and drones had been deployed near the waterway and that the group was awaiting an order to begin attacking shipping.

Edmund Fitton-Brown, a former British ambassador to Yemen and senior fellow at the Foundation for Defense of Democracies, warned in a recent Fox News Digital report that a full resumption of the Houthi maritime campaign could trigger wider fighting.

“It will be interesting if the Houthis do go all in, and resume their campaign against Red Sea shipping with full intensity,” Fitton-Brown said. “This will draw international anger and likely result in Israeli and U.S. strikes on Sana’a and Hodeida.”

“There is potential for a general escalation if this happens, albeit one in which the allies have a clear military advantage,” he added. 

Al-Dawsari said the Houthis have continued developing the weapons needed to threaten the narrow shipping corridor despite largely refraining from maritime attacks over the past year.

“While the Houthis have largely refrained from attacking shipping for about a year, they have continued to advance their maritime capabilities, including missiles, drones and sea mines,” she said. “They may not be able to fully close the strait, but they could significantly disrupt shipping and raise costs and risks for commercial traffic.”

US CLAWS BACK KEY CONCESSION TO IRAN AFTER FRESH ATTACKS ON COMMERCIAL SHIPS IN STRAIT OF HORMUZ

But the group would not necessarily need to physically control the waterway. Its previous missile and drone campaign demonstrated that repeated attacks — or even a credible threat of them — can push major shipping companies to reroute vessels around Africa, driving up insurance, fuel and freight costs.

The Bab el-Mandeb connects the Gulf of Aden to the Red Sea and Suez Canal, making it one of the world’s most important maritime choke points. The consequences of renewed attacks would be especially severe because Iran has already disrupted shipping through the Strait of Hormuz, historically the principal route for roughly one-fifth of global energy supplies.

A substantial volume of Gulf oil has consequently been redirected through Saudi Arabia to the Red Sea port of Yanbu. Reuters reported that the Bab el-Mandeb route now carries approximately 7% of global energy supplies and that Saudi Arabia has shifted about 70% of its energy exports through Yanbu.

The reported instructions also raise new questions about how much control Tehran exercises over major Houthi military decisions.

“Any decision to escalate in the Bab al-Mandab would be strategic and tied more to the interests of Iran and the Axis of Resistance than to Houthi interests alone,” Al-Dawsari said. “Decisions of this magnitude are likely coordinated through the Axis’ joint operations room under IRGC oversight.”

A source close to the Houthis claimed representatives of Iran’s Islamic Revolutionary Guard Corps in Yemen would control the timing of any move against the strait, Reuters reported.

The latest warning follows earlier Houthi threats against maritime traffic. In the June 12 report, Fox News Digital reported that the group had announced a complete ban on Israeli-owned ships in the Red Sea and declared them “legitimate targets.”

EXPERT WARNS OF ‘GENERAL ESCALATION’ OF FIGHTING IF HOUTHIS RESUME RED SEA CAMPAIGN

A State Department spokesperson told Fox News Digital at the time that the actions of Iran and the Houthis were “unacceptable” and “dangerous,” warning that they could inflame regional tensions and further disrupt global supply chains.

U.N. Secretary-General António Guterres has “repeatedly condemned” Houthis attacks against ships in the Red Sea and called on all parties Thursday to avoid further escalation, his spokesperson, Stéphane Dujarric, told Fox News Digital.

“Any disruptions or attacks would endanger the safety and security of seafarers, freedom of navigation and the stability of global supply chains and have a negative impact on the economic and humanitarian situation in Yemen and beyond,” Dujarric said. “The Secretary-General underscores that U.N. Security Council Resolution 2722 (2024) must be fully respected in its entirety,” he said on the resolution condemning at least two dozen Houthis attacks on commercial vessels since November 2023 and demanding an immediate end to the attacks. 

The emerging threat has also renewed scrutiny of the Iranian weapons networks that helped build the Houthis’ missile and drone arsenal.

Amr Al-Bidh, foreign affairs chief of the Southern Arabian Transitional Council, said that the reported threat also exposed broader failures in the handling of Yemen’s security crisis. “The fact that individuals convicted of trafficking Iranian weapons to the Houthis and leading terrorist operations are now being released under a U.N.-brokered deal only underscores how poorly the Yemen crisis is being managed,” he said, “the main beneficiary of this vacuum is Iran, as seen in its credible threat to close the Bab al-Mandab Strait.”

In a July 15 letter obtained by Fox News Digital, the Southern Arabian Transitional Council formerly known as the Southern Transitional Council, a southern Yemeni separatist movement that seeks greater autonomy or independence for the territory of the former South Yemen, warned U.N. Special Envoy for Yemen Hans Grundberg that a U.N.-facilitated detainee agreement may include people the council says were convicted of assisting Iranian weapons transfers to the Houthis.

The Office of the U.N. Special Envoy for Yemen said it received the letter only after the agreement had already been signed and stressed that it does not determine which detainees are released.

“We have received the letter after the agreement was signed,” spokesperson Ismini Palla told Fox News Digital. “The United Nations – as well as the International Committee of the Red Cross (ICRC) – do not decide who is released and who remains in detention. Our role is limited to mediating the negotiations and ICRC leads on the implementation of the release operation.”

Palla added that “the names of those released are proposed and agreed between the parties under the framework of the Stockholm Agreement on prisoners’ exchange of 2018.”

Fox News Digital reached out to the State Department and the Iranian Mission to the United Nations on the latest developments.
