More than 1.2 million years ago, an unknown group of human relatives may have created sharp hand axes from volcanic glass in a “stone-tool workshop” in what is now Ethiopia, a new study finds.

This discovery suggests that ancient human relatives may have regularly manufactured stone artifacts in a methodical way more than a half-million years earlier than the previous record, which dates to about 500,000 years ago in France and England.

Because it requires skill and knowledge, stone tool use among early hominins, the group that includes humans and the extinct species more closely related to humans than any other animal, can offer a window into the evolution of the human mind. A key advance in stone tool creation was the emergence of so-called workshops. At these sites, archaeologists can see evidence of hominins methodically and repeatedly crafting stone artifacts.

The newly analyzed trove of obsidian tools may be the oldest stone-tool workshop run by hominins on record. “This is very new in human evolution,” study first author Margherita Mussi (opens in new tab) , an archaeologist at the Sapienza University of Rome and director of the Italo-Spanish archeological mission at Melka Kunture and Balchit, a World Heritage site in Ethiopia, told Live Science.Oldest known hominin workshop

In the new study, the researchers investigated a cluster of sites known as Melka Kunture, located along the upper Awash River valley of Ethiopia. The Awash valley has yielded some of the best known examples of early hominin fossils, such as the famous ancient relative of humanity dubbed “Lucy.”

The scientists focused on 575 artifacts made of obsidian at a site known as Simbiro III in Melka Kunture. These ancient tools came from a layer of sand dubbed Level C, which fossil and geological data suggest is more than 1.2 million years old. 

These obsidian artifacts included more than 30 hand axes, or teardrop-shaped stone tools, averaging about 4.5 inches (11.5 centimeters) long and 0.7 pounds (0.3 kilograms). Ancient humans and other hominins may have used them for chopping, scraping, butchering and digging.

Obsidian proved far more rare at Simbiro III before and after Level C, and scarce in other Melka Kunture sites. The new excavations also revealed that Level C experienced seasonal flooding, with a meandering river likely depositing obsidian rocks at the site during this time of Level C. Obsidian axes from this level were far more regular in shape and size, which suggests mastery of the manufacturing technique.

Ancient hominins “are very often depicted as barely surviving, struggling with a hostile and changing environment,” Mussi said in an email from the field in Melka Kunture. “Here we prove instead that they were clever individuals, who did not miss the opportunity of testing any resource they discovered.”

This nearly exclusive use of obsidian at Level C of Simbiro III is unusual during the Early Stone Age, which ranged from about 3.3 million to 300,000 years ago, the researchers said. Obsidian tools can possess extraordinarily sharp cutting edges, but the volcanic glass is brittle and difficult to craft without smashing. As such, obsidian generally only found extensive use in stone tool manufacture beginning from the Middle Stone Age, which ranged from about 300,000 to 50,000 years ago, they said.

“The idea that ancient hominins of this era valued and made special use of obsidian as a material makes a lot of sense,” John Hawks (opens in new tab) , a paleoanthropologist at the University of Wisconsin–Madison who did not take part in this research, told Live Science. “Obsidian is widely recognized as uniquely valuable among natural materials for flaking sharp-edged tools; it is also highly special in appearance. Some historic cultures have used obsidian and traded it across distances of hundreds of miles.”

That trading may have gone on farther back than widely acknowledged.

“There has been evidence since the 1970s (opens in new tab) that obsidian may have been transported across long distances as early as 1.4 million years ago,” Hawks said. “That evidence has not been replicated by more recent excavation work, but the new report by Mussi and coworkers may be a step in that direction.”

It remains uncertain which hominin may have created these artifacts. Previously, at other Melka Kunture sites, researchers have discovered hominin remains about 1.66 million years old that may have been Homo erectus, and fossils about 1 million years old that may have been Homo heidelbergensis, Mussi said. H. erectus is the oldest known early human (opens in new tab) to possess body proportions similar to modern humans, whereas H. heidelbergensis may have been a common ancestor (opens in new tab) of both modern humans and Neanderthals, according to the Smithsonian. Since the age of Level C at Simbiro III is more than 1.2 million years old, the hominins that made the obsidian hand axes there may have been closer in nature to H. erectus, Mussi said.

The scientists detailed their findings Jan. 19 in the journal Nature Ecology and Evolution (opens in new tab) .

UK content creators demand formal recognition from the government

The UK’s YouTubers, TikTok creators and Instagram influencers have been surveyed en masse for the first time ever, and are demanding formal recognition from the government.

The creator economy in the UK is thought to employ around 45,000 people and contribute over £2bn to the country in one year alone, according to the new research by YouTube and Public First.

But, despite all that value, its workers say they feel underappreciated by the authorities.

“If you look at the viewership, our channel is not too different from a big media company,” said Max Klymenko, a content creator with more than 10 million subscribers and half a billion monthly views on average.

“If you look at the relevancy, especially among young audiences, I will say that we are more relevant. That said, we don’t really get the same treatment,” he told Sky News.

Fifty-six per cent of the more than 10,000 creators surveyed said they do not think UK creators have a “voice in shaping government policies” that affect them.

Only 7% think they get enough support to access finance, while just 17% think there is enough training and skills development here in the UK.

Nearly half think their value is not recognised by the broader creative industry.

The creative industries minister, Sir Chris Bryant, said the government “firmly recognises the integral role that creators play” in the UK’s creative industries and the fact that they help “to drive billions into the economy” and support more than 45,000 jobs.

“We understand more can be done to help creators reach their full potential, which is why we are backing them through our new Creative Industries Sector Plan,” he said.

“The UK has got a fantastic history of supporting the creative industries,” said Ben Woods, a creator economy analyst, Midia Research who was not involved in the report.

“Whether you look at the film side, lots of blockbuster films are being shot here, or television, which is making waves on the global stage.

“But perhaps the government needs to broaden that lens a little bit to look at just what’s going on within the creator economy as well, because it is highly valuable, it’s where younger audiences are spending a lot of their time and [the UK is] really good at it.”

According to YouTube, formal recognition would mean creators are factored into official economic impact data reporting, are represented on government creative bodies, and receive creator-specific guidance from HMRC on taxes and finances.

For some, financial guidance and clarity would be invaluable; the ‘creator’ job title seems to cause problems when applying for mortgages or bank loans.

“It’s really difficult as a freelancer to get things like mortgages and bank accounts and credit and those types of things,” said podcaster David Brown, who owns a recording studio for creators.

“A lot of people make very good money doing it,” he told Sky News.

“They’re very well supported. They have a lot of cash flow, and they are successful at doing that job. It’s just the way society and banking and everything is set up. It makes it really difficult.”

The creative industries minister said he is committed to appointing a creative freelance champion and increasing support from the British Business Bank in order to “help creators thrive and drive even more growth in the sector”.

The government has already pledged to boost the UK’s creative industries, launching a plan to make the UK the number one destination for creative investment and promising an extra £14bn to the sector by 2035.

These influencers want to make sure they are recognised as part of that.

Astros' Alvarez to see hand specialist after setback

DENVER — Houston Astros slugger Yordan Alvarez has experienced a setback in his recovery from a broken right hand and will see a specialist.

Astros general manager Dana Brown said Alvarez felt pain when he arrived Tuesday at the team’s spring training complex in West Palm Beach, Florida, where he had a workout a day earlier. Alvarez also took batting practice Saturday at Daikin Park.

He will be shut down until he’s evaluated by the specialist.

“It’s a tough time going through this with Yordan, but I know that he’s still feeling pain and the soreness in his hand,” Brown said before Tuesday night’s series opener at Colorado, which the Astros won 6-5. “We’re not going to try to push it or force him through anything. We’re just going to allow him to heal and get a little bit more answers as to what steps we take next.”

Alvarez has been sidelined for nearly two months. The injury was initially diagnosed as a muscle strain, but when Alvarez felt pain again while hitting in late May, imaging revealed a small fracture.

The 28-year-old outfielder, who has hit 31 homers or more in each of the past four seasons, had been eyeing a return as soon as this weekend at the Los Angeles Dodgers. Now it’s uncertain when he’ll play.

“We felt like he was close because he had felt so good of late,” Brown said, “but this is certainly news that we didn’t want.”

Also Tuesday, the Astros officially placed shortstop Jeremy Peña on the 10-day injured list with a fractured rib and recalled infielder Shay Whitcomb from Triple-A Sugar Land.

Springer's 7 RBIs help Jays pile on Yankees late

George Springer had a career-high seven RBIs, including his ninth grand slam, and the Toronto Blue Jays celebrated Canada Day by beating the Yankees 12-5 on Tuesday and closing within one game of American League East-leading New York.

The seven RBIs are tied for the second most by any Blue Jays player in a home game, behind Edwin Encarnación (nine RBIs in 2015), according to ESPN Research.

Andrés Giménez had a go-ahead, three-run homer for the Blue Jays, who overcame a 2-0 deficit against Max Fried. After the Yankees tied the score 4-4 in the seventh, Toronto broke open the game in the bottom half against a reeling Yankees bullpen.

Springer went 3-for-4, starting the comeback with a solo homer in the fourth against Fried and boosting the lead to 9-5 with the slam off Luke Weaver after Ernie Clement‘s go-ahead single off shortstop Anthony Volpe‘s glove. Springer has 13 homers this season.

Toronto won the first two games of the four-game series and closed within one game of the Yankees for the first time since before play on April 20.

New York went 2-for-17 with runners in scoring position, dropping to 3-for-24 in the series, while the Blue Jays were 5-for-7. After going 13-14 in June, the Yankees fell to 10-14 against AL East rivals.
