Oldest human relative walked upright 7 mn years ago: study

The earliest known human ancestor walked on two feet as well as climbing through trees around seven million years ago, scientists said Wednesday after studying three limb bones.

When the skull of Sahelanthropus tchadensis was discovered in Chad in 2001, it pushed back the age of the oldest known representative species of humanity by a million years.

Nicknamed “Toumai”, the nearly complete cranium was thought to indicate that the species walked on two feet because of the position of its vertebral column and other factors.

However the subject triggered fierce debate among scientists, partly due to the scarcity and quality of the available bones, with some even claiming that Toumai was not a human relative but just an ancient ape.

In a study published in the Nature journal on Wednesday, a team of researchers exhaustively analysed a thigh bone and two forearm bones found at the same site as the Toumai skull.

“The skull tells us that Sahelanthropus is part of the human lineage,” said paleoanthropologist Franck Guy, one of the authors of the study.

The new research on the limb bones demonstrates that walking on two feet was its “preferred mode of getting around, depending on the situation,” he told a press conference.

But they also sometimes moved through the trees, he added.

– ‘Not a magical trait’ –

The leg and arm bones were found alongside thousands of other fossils in 2001, and the researchers were not able to confirm that they belonged to the same individual as the Toumai skull.

After years of testing and measuring the bones, they identified 23 characteristics which were then compared to fossils from great apes as well as hominins — which are species more closely related to humans than chimpanzees.

They concluded that “these characteristics are much closer to what would be seen in a hominin than any other primate,” the study’s lead author Guillaume Daver told the press conference.

For example, the forearm bones did not show evidence that the Sahelanthropus leaned on the back of its hands, as is done by gorillas and chimpanzees.

The Sahelanthropus lived in an area with a combination of forests, palm groves and tropical savannahs, meaning that being able to both walk and climb through trees would have been an advantage.

There have been previous suggestions that it was the ability to walk on two feet that drove humans to evolve separately from chimpanzees, putting us on the path to where we are today.

However the researchers emphasised that what made Sahelanthropus human was its ability to adapt to its environment.

“Bipedalism (walking on two legs) is not a magical trait that strictly defines humanity,” paleontologist Jean-Renaud Boisserie told the press conference.

“It is a characteristic that we find at the present time in all the representatives of humanity.”

– Our ‘bushy’ family tree –

Paleoanthropologist Antoine Balzeau of France’s National Museum of Natural History said the “extremely substantial” study gives “a more complete image of Toumai and therefore of the first humans”.

It also bolstered the theory that the human family tree is “bushy”, and was not like the “simplistic image of humans who follow one another, with abilities that improve over time,” Balzeau, who was not involved in the research, told AFP.

Daniel Lieberman, a professor of human evolutionary biology at Harvard University, said in a linked paper in Nature that the study’s “authors have squeezed as much information as possible from the fossil data”.

But he added that the research will not offer “full resolution” of the debate.

Milford Wolpoff, a paleoanthropologist at the US University of Michigan cast doubt on whether Toumai is a hominin, telling AFP that “extraordinary claims require extraordinary evidence”.

Wednesday’s study was carried out by researchers from the PALEVOPRIM paleontology institute, a collaboration between France’s CNRS research centre and Poitiers University, as well as scientists in Chad.

Guy said the team hopes to continue its research in Chad next year — “security permitting”.

Chadian paleontologist Clarisse Nekoulnang said the team was “trying to find sites older than that of Toumai”.

Epstein Denies Being ‘the Devil’ in Newly Released Video Interview

Jeffrey Epstein claims he was the least dangerous type of sex offender and denied being “the devil” in a video interview included in the latest batch of documents released over the weekend by the U.S. Department of Justice.

The roughly two-hour interview was conducted by Steve Bannon, a former adviser to U.S. President Donald Trump, and appears to have been recorded at the late financier’s New York residence on an unknown date.

Epstein died by suicide in 2019 while in jail awaiting trial on sex trafficking charges involving minors. Since December, the U.S. government has released millions of documents related to the case under transparency laws.

“Do you think you’re the devil incarnate?” Bannon asks Epstein in the video interview revealed in the latest release.

“No, but I do have a good mirror,” Epstein replies with a smile, wearing a black shirt and glasses. When pressed again, he adds, “I don’t know. Why would you say that?”

Epstein, who pleaded guilty in 2008 to soliciting a minor for prostitution, also appears to downplay the seriousness of his conviction.

He objects when Bannon refers to him as a “Level Three sexual predator,” a classification in the United States indicating a very serious threat to public safety.

“No, I’m the lowest,” Epstein says.

“But still an offender,” Bannon responds.

“Yes,” Epstein replies.

The exchange comes after Bannon asks Epstein whether he considers his wealth to be “dirty,” suggesting it was earned by advising “the worst people in the world.”

Epstein insists that he made his money legally, while acknowledging that “ethics is always a complicated issue.”

He claims he donated money to help eradicate polio in Pakistan and India, apparently in an attempt to justify the origins of his fortune.

The documents also show that Bannon maintained regular correspondence with Epstein, who offered to help the far-right political figure spread his conservative ideology in Europe.

Since Trump took office in January 2025, U.S. authorities have released millions of pages related to Epstein, along with photos and videos.

These materials have shed new light on Epstein’s ties to high-profile business executives such as Microsoft co-founder Bill Gates, celebrities including filmmaker Woody Allen, and academics and political figures, among them Trump and former President Bill Clinton.

Hypothermia Linked to Most Deaths During New York’s Recent Cold Spell

Hypothermia “played a role” in 13 of the 16 deaths recorded in New York City during the recent period of extreme cold, Mayor Mandami said at a press conference. Three of the deaths were classified as drug overdoses.

None of the individuals were sleeping on the streets at the time of their deaths, the mayor added, noting that some had previously been in contact with emergency shelter services.

Mandami said the city has activated emergency warming centers and deployed a fleet of 20 vehicles staffed with medical personnel to respond to the cold weather crisis.

“As of this morning, we have made more than 930 referrals to shelters and safe facilities. We have also involuntarily transported 18 New Yorkers who were deemed a danger to themselves or others,” he said.

According to official statistics, New York City recorded between nine and 27 cold-related deaths per year from 2005 to 2021. That number rose to 34 in 2021 and climbed further to 54 in 2022.

City Comptroller Mark Levine estimated that there are “tens of thousands” of homeless New Yorkers, “most of them families with children.”

He said that “nearly 95%” of the city’s homeless population lives in municipal shelters.

In August 2021, those shelters housed 44,586 people, the “lowest daily population in nearly a decade,” according to official data.

However, the shelter population increased from 22,955 to 62,679 people between January 2000 and January 2020, highlighting the long-term growth of homelessness in the city.

NFL Investigating Emails Linking Giants Executive to Jeffrey Epstein

NFL Commissioner Roger Goodell said on Monday that the league will “examine all the facts” regarding contacts between New York Giants co-owner Steve Tisch and Jeffrey Epstein, revealed in documents recently released about the late convicted sex offender.

The batch of files, made public on Friday by the U.S. Department of Justice, includes emails suggesting that Epstein introduced several women to Tisch.

Tisch, a film producer who has never been charged in connection with Epstein, issued a statement last week denying any wrongdoing.

“I had a brief relationship in which we exchanged emails about adult women, and we also discussed film, philanthropy, and investments,” Tisch said of his correspondence with Epstein, which dates back to 2013.

“I did not accept any of his invitations and never went to his island. As we all now know, he was a terrible person and someone I deeply regret having associated with,” he added.

Speaking at a press conference in San Jose, California, on Monday, Goodell said the NFL would carefully review the details of the ties between Tisch and Epstein.

“We’re going to examine all the facts,” the commissioner said. “We’re going to look at the context of those exchanges, try to understand them, and see how that fits within the league’s policies.”

Tisch, 76, could face disciplinary action under the NFL’s strict personal conduct policy, even if he is not found guilty of a crime.

“We’re going to take this step by step. First, let’s gather all the facts,” Goodell said at the press conference, which was part of the events leading up to Sunday’s Super Bowl between the Seattle Seahawks and the New England Patriots.
