It was long thought that modern humans first ventured into Europe about 42,000 years ago, but newly analyzed tools from the Stone Age have upended this idea. Now, evidence suggests that modern humans trekked into Europe in three waves between 54,000 and 42,000 years ago, a new study finds.

Our species, Homo sapiens, arose in Africa more than 300,000 years ago, and anatomically modern humans emerged at least 195,000 years ago. Evidence for the first waves of modern humans outside Africa dates back at least 194,000 years to Israel, and possibly 210,000 years to Greece.

For years, the oldest confirmed signs of modern humans in Europe were teeth about 42,000 years old that archaeologists had unearthed in Italy and Bulgaria. These ancient groups were likely Protoaurignacians — the earliest members of the Aurignacians, the first known hunter-gatherer culture in Europe.

However, a 2022 study revealed that a tooth found in the site of Grotte Mandrin (opens in new tab) in southern France’s Rhône Valley suggested that modern humans lived there about 54,000 years ago, a 2022 study found. This suggested Europe was home to modern humans about 10,000 years earlier than previously thought. 

In the 2022 study, scientists linked this fossil tooth with stone artifacts that scientists previously dubbed Neronian, after the nearby Grotte de Néron site. Neronian tools include tiny flint arrowheads or spearpoints and are unlike anything else found in Europe from that time.

Now, in a new study, an archaeologist argues that another wave of modern humans may have entered Europe between the 42,000-year-old Protoaurignacians and the 54,000-year-old Neronians. “It’s an in-depth rewriting of the historical structure of [the] arrival of sapiens in the continent,” study lead researcher Ludovic Slimak (opens in new tab) , an archaeologist at the University of Toulouse in France, told Live Science in an email. He detailed his ideas in a study published on Wednesday (May 3) in the journal PLOS One (opens in new tab) .Image 1 of 3These maps show evidence for three distinct waves of early migration of Homo sapiens in Europe from the East Mediterranean coast.

Slimak focused on a group or “industry” of stone artifacts previously unearthed in the Levant, the eastern Mediterranean region that today includes Israel, Palestine, Jordan, Lebanon and Syria. Scientists have long thought that the Levant was a key gateway for modern humans migrating out of Africa.

When Slimak compared Neronian tools from Grotte Mandrin with the industry from about the same time from a site known as Ksar Akil in Lebanon, he found notable similarities. This suggested both groups were one and the same, with the Levantine group expanding into Europe over time. The much younger Protoaurignacian artifacts also have very similar counterparts in the Levant from a culture known as the Ahmarian, Slimak noted. 

“I buil[t] a bridge between Europe and the East Mediterranean populations during the early migrations of sapiens in the continent,” Slimak said.

In addition, Slimak found thousands of modern human flint artifacts from the Levant that existed in the period known as the Early Upper Paleolithic, between the Ksar Akil and the Ahmarian ones. This led him to look for possible modern human counterparts of these artifacts in Europe.

Stone artifacts from a European industry known as the Châtelperronian highly resemble modern human artifacts seen in the Early Upper Paleolithic of the Levant. In addition, Châtelperronian items date to about 45,000 years ago, or between those of the Neronians and the Protoaurignacians. However, scientists had often thought Châtelperronians were Neanderthals.Related stories—Unknown lineage of ice age Europeans discovered in genetic study

Slimak now argues the Châtelperronians were actually a second wave of modern humans into Europe. “We have here, and for the first time, a serious candidate for a non-Neanderthalian origin of these industries,” Slimak said. 

This new model of modern human settlement of Europe is “ambitious and provocative,” Chris Stringer (opens in new tab) , a paleoanthropologist at the Natural History Museum in London who did not take part in the new study, told Live Science in an email. “Evidence has been building for a while that there were several early dispersals of Homo sapiens into Europe before the well-attested Aurignacian-associated one about 42,000 years ago.”

Future research can help confirm or disprove this new idea. “I see this paper generating a number of research projects to support or refute it,” Christian Tryon (opens in new tab) , a Paleolithic archaeologist at the University of Connecticut who helped translate the new study, told Live Science in an email. “People now need to look at some of the archaeological sites here with a critical eye to see if they see the same kinds of technical details reported by Slimak. This is the start of a long process, I suspect.”

Hundreds of UK moderators have left TikTok - sparking safety fears, whistleblowers reveal

Hundreds of UK online safety workers at TikTok have already signed agreements to leave the company, whistleblowers have told Sky News, despite the firm stressing to MPs that the cuts were “still proposals only”.

More than 400 online safety workers have agreed to leave the social media company, with only five left in consultation, Sky News understands.

“[The workers have] signed a mutual termination agreement, a legally binding contract,” said John Chadfield, national officer for the Communication Workers’ Union.

“They’ve handed laptops in, they’ve handed passes in, they’ve been told not to come to the office. That’s no longer a proposal, that’s a foregone conclusion. That’s a plan that’s been executed.”

In August, TikTok announced a round of mass layoffs to its Trust and Safety teams.

“Everyone in Trust and Safety” was emailed, said Lucy, a moderator speaking on condition of anonymity for legal reasons.

After a mandatory 45-day consultation period, the teams were then sent “mutual termination agreements” to sign by 31 October.

Sky News has seen correspondence from TikTok to the employees telling them to sign by that date.

“We had to sign it before the 31st if we wanted the better deal,” said Lucy, who had worked for TikTok for years.

“If we signed it afterwards, that diminished the benefits that we get.”

Despite hundreds of moderators signing the termination contracts by 31 October, Ali Law, TikTok’s director of public policy and government affairs for northern Europe, said to MPs in a letter on 7 November: “It is important to stress the cuts remain proposals only.”

“We continue to engage directly with potentially affected team members,” he said in a letter to Dame Chi Onwurah, chair of the science, innovation and technology committee.

After signing the termination contracts, the employees say they were asked to hand in their laptops and had access to their work systems revoked. They were put on gardening leave until 30 December.

“We really felt like we were doing something good,” said Saskia, a moderator also speaking under anonymity.

“You felt like you had a purpose, and now, you’re the first one to get let go.”

A TikTok worker not affected by the job cuts confirmed to Sky News that all of the affected Trust and Safety employees “are now logged out of the system”.

“Workers and the wider public are rightly concerned about these job cuts that impact safety online,” said the TUC’s general secretary, Paul Nowak.

“But TikTok seem to be obscuring the reality of job cuts to MPs. TikTok need to come clean and clarify how many vital content moderators’ roles have gone.

“The select committee must do everything to get to the bottom of the social media giant’s claims, the wider issues of AI moderation, and ensure that other workers in the UK don’t lose their jobs to untested, unsafe and unregulated AI systems.”

What TikTok has said about the job cuts

In an interview with Sky News on 18 November, Mr Law again called the cuts “proposals”.

When asked if the cuts were in fact a plan that had already been executed, Mr Law said there was “limited amounts” he could directly comment on.

TikTok told us: “It is entirely right that we follow UK employment law, including when consultations remained ongoing for some employees and roles were still under proposal for removal.

“We have been open and transparent about the changes that were proposed, including in detailed public letters to the committee, and it is disingenuous to suggest otherwise.”

The three whistleblowers Sky News spoke to said they were concerned TikTok users would be put at risk by the cuts.

The company said it will increase the role of AI in its moderation, while maintaining some human safety workers, but one whistleblower said she didn’t think the AI was “ready”.

“People are getting new ideas and new trends are coming. AI cannot get this,” said Anna, a former moderator.

“Even now, with the things that it’s supposed to be ready to do, I don’t think it’s ready.”

Is TikTok improving safety with AI?

Lucy also said she thought the cuts would put users at risk.

“There are a lot of nuances in the language. AI cannot understand all the nuances,” she said.

“AI cannot differentiate some ironic comment or versus a real threat or bullying or of a lot of things that have to do with user safety, mainly of children and teenagers.”

TikTok has been asked by MPs for evidence that its safety rates – which are currently some of the best in the industry – will not worsen after these cuts.

The select committee says it has not produced that evidence, although TikTok insists safety will improve.

“[In its letter to MPs] TikTok refers to evidence showing that their proposed staffing cuts and changes will improve content moderation and fact-checking – but at no point do they present any credible data on this to us,” said Dame Chi earlier this month.

“It’s alarming that they aren’t offering us transparency over this information. Without it, how can we have any confidence whether these changes will safeguard users?”

TikTok’s use of AI in moderation

In an exclusive interview with Sky News earlier this month, Mr Law said the new moderation model would mean TikTok can “approach moderation with a higher level of speed and consistency”.

He said: “Because, when you’re doing this from a human moderation perspective, there are trade-offs.

“If you want something to be as accurate as possible, you need to give the human moderator as much time as possible to make the right decision, and so you’re trading off speed and accuracy in a way that might prove harmful to people in terms of being able to see that content.

“You don’t have that with the deployment of AI.”

As well as increasing the role of AI in moderation, TikTok is reportedly offshoring jobs to agencies in other countries.

Sky News has spoken to multiple workers who confirmed they’d seen their jobs being advertised in other countries through third-party agencies, and has independently seen moderator job adverts in places like Lisbon.

“AI is a fantastic fig leaf. It’s a fig leaf for greed,” said Mr Chadfield. “In TikTok’s case, there’s a fundamental wish to not be an employer of a significant amount of staff.

“As the platform has grown, as it has grown to hundreds of millions of users, they have realised that the overhead to maintain a professional trust and safety division means hundreds of thousands of staff employed by TikTok.

“But they don’t want that. They see themselves as, you know, ‘We want specialists in the roles employed directly by TikTok and we’ll offshore and outsource the rest’.”

Mr Law told Sky News that TikTok is always focused “on outcomes”.

He said: “Our focus is on making sure the platform is as safe as possible.

“And we will make deployments of the most advanced technology in order to achieve that, working with the many thousands of trust and safety professionals that we will have at TikTok around the world on an ongoing basis.”

Asked specifically about the safety concerns raised by the whistleblowers, TikTok said: “As we have laid out in detail, this reorganisation of our global operating model for Trust and Safety will ensure we maximize effectiveness and speed in our moderation processes.

“We will continue to use a combination of technology and human teams to keep our users safe, and today over 85% of the content removed for violating our rules is identified and taken down by automated technologies.”

‘If someone took Trump’s land, how would he feel?’ – Ukrainians view peace talks with suspicion

'If someone took Trump's land, how would he feel?' - Ukrainians view peace talks with suspicion

A Ukrainian farmer-turned-soldier in the Donbas has a message for Donald Trump as the US president attempts to broker a peace deal between Kyiv and Moscow.

Anatolii, 59, said: “If someone took a piece of his territory, what would he say to that? The same goes for us.”

Like many Ukrainians, the serviceman volunteered to join a territorial defence unit when Russia launched its full-scale war almost four years ago.

He has been fighting ever since, but will have the option to quit next year once he turns 60.

Unable to wear body armour anymore because of its weight, Anatolii now operates further back from the frontline in a small workshop on the outskirts of the city of Kramatorsk where he helps to fix and improve the performance of drones – a crucial weapon on the battlefield.

“I want this war to finally end,” he said. “I want to go home, to my family, to my land.”

But not at any price.

Peace deal: Russia ‘in no mood to compromise’.

An initial proposal envisaged the Ukrainian government giving up Donetsk and Luhansk, the two regions that make up the Donbas, to Russia.

This includes large swathes of land that are still under Ukraine’s control, and that thousands of Ukrainian soldiers have lost their lives fighting to defend.

“I feel negative about it,” Anatolii said, referring to the proposal.

“So many people already fell for this land … How can we give away our land? It would be like someone comes to my house and says: ‘Give me a piece of your home.'”

However, he added: “I understand, we have nothing to take it back with. Maybe through some political means…

“I do not want more people to fall, more people to die. I want politicians to somehow come to terms.”

A short drive away from the workshop is a hidden bomb factory where other soldiers from the same unit are focused on a different kind of war effort.

Surrounded by 3D printed gadgets, metal ball bearings and plastic explosives, they make improvised bombs, including anti-personnel mines and devices that can be fitted onto one-way attack drones and exploded onto targets.

Vadym, 41, is in charge of the production line.

He has been fighting since Russian President Vladimir Putin first attacked eastern Ukraine in 2014.

Asked whether he felt tired, he said: “We are always tired, we have no motivation as such, but there is the understanding that the enemy will keep coming as long as we do not stop him. If we stop fighting, our children and grandchildren will fight. That keeps us going.”

Vadym is also against simply handing over Ukrainian land to Russia.

“If we now give away borders, give away Donbas, then what?” he said.

“Any country can come to any other country and say: This is our land. Let’s coordinate, do business, and keep living as before. That is not normal in my view.”

The Ukrainian president says ‘everyone must be on this side of peace’

The city of Kramatorsk stands testament to Ukraine’s will to fight, remaining firmly in Ukrainian hands, though Russia’s war is inching closer.

Nets stretched like a tunnel line a main road leading into the city to protect vehicles from the threat of small, killer drones.

Coils of barbed wire are also strung across fields around the outskirts of Kramatorsk along with other fortifications such as mounds of dirt and triangular lumps of concrete.

Many civilians have remained here as well as the nearby city of Slovyansk, even as other landmark sites such as Mariupol, Bakhmut and Avdiivka have fallen.

Yet the toll of living in a warzone is clear.

Stallholders swept away rubble and broken glass on Sunday after a Russian missile smashed into a central market in Kramatorsk on Saturday night.

Some, like Ella, 60, even chose to reopen despite the carnage.

“It’s frightening. We need to earn a living. I have my mother, I need to look after her, help my children. So we do what we have to do,” she said.

Her adult children live in Kyiv and want her to leave, but Kramatorsk is her home.

“We’ve been living like this for four years now. We’re so used to it. A drone flies overhead and we keep working,” she said.

Is the UK prepared to fight a war?

Asked how she felt about what the war had done to her city, Ella’s voice wobbled and she wiped tears from her eyes.

“We keep it all inside, but it still hurts. It’s frightening and painful. I just want things as they used to be. We don’t want anything here to change,” she said.

As for what she would do if a future peace deal forced Ukraine to surrender the area, Ella said: “That’s a hard question … I wouldn’t stay. I’d leave.”

3.3-magnitude earthquake shakes part of northwest England

A 3.3-magnitude earthquake has struck Lancashire – with dozens of people saying it shook their homes or woke them up.

The British Geological Society (BGS) told Sky News it was “felt across the South Lakes and Lancashire, mainly within 20km of the epicentre”, including Kendal and Ulverston in neighbouring Cumbria.

Preliminary data suggests it struck off the coast of Silverdale at 11.23pm, at a depth of 1.86 miles (3km).

Each year, between 200 and 300 earthquakes are detected and located in the UK by the BGS.

Between 20 and 30 earthquakes are felt by people each year, and a few hundred smaller ones are only recorded by sensitive instruments.

Most of these are very small and cause no damage.

People posted their reaction online. Reports included that the earthquake “felt like an explosion and vibration coming from underground”.

More from UK

Another comment said it “sounded like bricks falling/the roof falling in”, while another wrote that it was “so powerful to shake the whole house”.
