New Research Suggests Humans Arrived in the Americas Much Earlier Than Thought

Published

on

(Inside Science) — The Americas may have been home to humans for more than 12,000 years longer than previously thought, new research finds.

The arrival of humans to the Americas from Asia marked a major step in humanity’s journey across the globe, but the exact timing of this entry remains hotly debated. Based on stone tools dating back about 13,000 years, archaeologists long thought the first Americans were part of a prehistoric culture known as the Clovis. However, scientists have recently uncovered many sites that suggested humans were in the New World before Clovis, up to roughly 18,000 years ago. Now new studies extend that time to more than 30,000 years ago.

In the new work, researchers focused on Mexico, which is typically on the periphery of the hunt for the first Americans, given its distance from the Bering Strait and Beringia, the landmass that had connected Asia and North America. However, recent findings have unearthed hints of an ancient human presence in Mexico.

The scientists investigated Chiquihuite Cave in the Astillero Mountains of central Mexico, the most promising of dozens of sites they explored in the region. They spent a number of winters excavating a 3-meter-deep pit 50 meters from the cave’s mouth. They lived inside the cave for seven to nine weeks in a row during the winters, cooking in the area and sleeping meters away from the dig while wary of drug cartels said archaeologist Ciprian Ardelean at the Autonomous University of Zacatecas in Mexico.

Ardelean and his colleagues unearthed about 1,900 stone artifacts. Radiocarbon and optically stimulated luminescence dating of the objects suggest humans might have occupied the area 31,000 to 33,000 years ago. Given how far away Chiquihuite is from the coasts, much less Asia, the researchers suggest humans may have first arrived in the New World during a period 29,000 to 57,000 years ago. They detailed their findings in two studies in the July 23 issue of the journal Nature.

These newfound artifacts show a tool manufacturing style, or “lithic industry,” never previously known in the New World. “Actually, all pre-Clovis sites in the Americas have lithic industries that don’t match each other,” Ardelean said. “This seems to be the norm.”

The cave is located roughly 2,740 meters above sea level (nearly 9,000 feet), almost on the top of the highest mountain in the region. Archaeologists looking for ancient sites in the New World typically focus on lake shores, rolling hills and other areas that we might find comfortable, Ardelean said. “I wanted to search for sites in all sorts of locations, even where we wouldn’t go to live as modern people. The ice age was a different world, with different minds and psychologies, more courageous than ours. They were adapted to mountains, and for them, it must have been just normal.” Although the area is now part of the southernmost section of the giant Chihuahuan desert, it was more like the Pacific Northwest during the last ice age, Ardelean said.

“We anticipate that the results will spur new interest in surveying regions like this for new sites,” said archaeological scientist Thomas Higham at the University of Oxford in England, a co-author on both studies. The fact that a high-altitude site such as Chiquihuite “contains earlier human presence will invite archaeologists to widen the places they seek to look for early archaeological sediments.”

When the scientists examined the age of Chiquihuite and 41 other archaeological sites in North America and Beringia, their computer model suggested humans were likely present in the Americas before, during and immediately after the Last Glacial Maximum — the period around 19,000 to 26,500 years ago when the ice age was at its peak and glaciers covered roughly one-third of Earth’s land. During such early times, a land passage to the New World would have been blocked by either treacherous open water or impenetrable ice sheets, suggesting “the path humans took to the Americas was likely a coastal route,” Becerra-Valdivia said.

“It changes our comprehension of the settlement of the Americas considerably,” said bioanthropologist Mark Hubbe at the Ohio State University in Columbus, who was not involved in this work. “There have been a few sites in South America that have claimed earlier human occupations, but most of them have been largely dismissed because of a combination of unreliable evidence and the fact that they were such chronological outliers that it is more parsimonious to assume the dates were wrong. It is nice to see that we are broadening our perspective and allowing for the possibility that the Americas may have been occupied significantly longer than we ever thought possible.”

Archaeologist John Hoffecker at the University of Colorado at Boulder, who did not participate in this study, noted that “for more than a decade and half, evidence of people in Beringia before the end of the Last Glacial Maximum has been accumulating,” lending credence to a possible ancient human presence in Mexico. Still, “it continues to strike me as odd that, if people were present in the Western Hemisphere outside eastern Beringia at this earlier time, the evidence for their presence is so sparse, because at this time in northern Eurasia, people are all over the place, occupying large sites with abundant artifacts, many features, and heaps of food debris.”

However, sparse evidence of humans in the New World during the last ice age “is not surprising; the harshness of the Last Glacial Maximum would have kept populations low, leaving little trace behind for archaeologists to discover in the future,” Becerra-Valdivia said. “Once a warming period began, humans were then able to thrive and expand across the region.”

Ardelean cautioned that scientists still need to discover more similarly early sites to confirm a human presence in the New World during or before the Last Glacial Maximum. “The evidence is still very scarce and blurry,” Ardelean said. “Chiquihuite is simply a very dim light in a vast darkness ignored so far.”

Future research can investigate how related or not these ancient Americans were to later groups. “Did they contribute to form Native Americans, or were they an unsuccessful attempt to occupy the continent that was later replaced by the ancestors of Native Americans?” Hubbe said.

“We need to start exploring underwater sites, as has recently been done in Australia,” added geographer Umberto Lombardo, who did not take part in this research. A research program taking hundreds of core samples along the coasts of North and Central America would cost a lot, “but it could be done by a large consortium of universities.”

Women in the newsroom: Why South Africa leads the way

Published

on

Mahlatse Mahlase is group editor-in-chief of Eyewitness News, a major broadcaster in South Africa. It’s a role she would have been unlikely to fill 30 years ago, under the apartheid regime, whose hierarchy put Black women on a bottom tier.

But no matter where you look in the world, women’s leadership in the news media has lagged – and still does. South Africa, in fact, is a relative success story. Today, women lead nearly half of the country’s major publications and broadcasters, according to a recent analysis by Oxford University. That puts it ahead of the United States, the United Kingdom, and even countries held up as models of gender parity, like Finland.

Yet South African women’s gains have been especially hard-won, and incomplete. Women hold few of journalism’s purse strings, for instance. 

Ms. Mahlase says she has reflected on representation through a new prism since she gave birth seven months ago to her first child, a boy. 

“I want my son to grow up in a world where he has female bosses,” she says. “I want him to grow up listening to women experts on the radio, hearing them as contributors to changing the world and not just as victims of an unfair system.”

Nwabisa Makunga can point to the exact moment she knew she would become a journalist.

It was April 1993 and she was 11 years old, watching the TV broadcast of the funeral of assassinated anti-apartheid leader Chris Hani with her family in their living room. The presenter was a Black reporter named Noxolo Grootboom, and her powerful tribute to Mr. Hani brought Ms. Makunga’s parents to tears.

“She was a woman who looked like me, who spoke like me, telling the story of a man who had been so important to people from my community,” she recalls. “I said to myself – this is what I’m going to do. I’m going to be like Noxolo, and I’m going to tell stories.”

Three decades later, Ms. Makunga is the editor-in-chief of the Sowetan, one of South Africa’s most-circulated daily newspapers. She is part of a generation of women who have risen through the ranks to take leadership of many of the country’s most important news outlets. Today, these women – most of them Black, Asian, and multiracial – lead nearly half the country’s major publications and broadcasters, according to a recent analysis by Oxford University. That makes the country a global leader for women’s leadership in the media, putting it ahead of the United States, the United Kingdom, and even countries held up as models of gender parity, like Finland.

And the achievement is doubly remarkable in South Africa, where only a generation ago the entire country was run largely by white men. Editors like Ms. Makunga grew up not only with few role models who looked like them, but also in a world where the media was used as a weapon of the apartheid regime, premised on white supremacy – enforcing a hierarchy in which they were the bottom tier.

Hard-won gains

Even after apartheid formally ended, these editors came up in newsrooms where its effects lingered. They were told their accents were “too African,” or their looks “too tempting.” Even as the newsrooms around them began to change from mostly white to mostly not, they still found themselves edged out of the pub trips and golf games where their male colleagues networked their way to the top.

“Make no mistake: Those statistics changing are the result of a fight,” says Mahlatse Mahlase, group editor-in-chief of Eyewitness News, a major breaking-news broadcaster. Women in South Africa’s newsrooms “have fought racism and they’ve also fought the patriarchy. The discrimination came from every side.”

Although they’ve now arrived, many of these same leaders note that South Africa’s media transformation remains incomplete. Women hold few of journalism’s purse strings, for instance. Just 19% of the board members at media companies here are female, according to a 2018 academic study of women in the media called “Glass Ceilings.” The vast majority of the country’s major media houses have a male CEO.

And while the proportion of Black, Asian, and multiracial women in the top echelons of South African media companies has grown from 6% in 2006 to 30% in 2018, that number still lags, in a country where they represent 46% of the population, according to the Glass Ceilings survey. Once they get there, meanwhile, they’re often placed under intense scrutiny and pressure.

“When men get to the top of their profession, they’re celebrated. When women get there, particularly Black women, there’s backlash, there’s trolling, there’s bullying,” says Glenda Daniels, an associate professor of media studies at the University of the Witwatersrand in Johannesburg and the co-author of the Glass Ceilings study. She uses the term “Black” as it is frequently applied in South Africa, to describe anyone who is not white. “Women at the top find they’re often exhausted just proving over and over that they deserve to be in the room.”

“Newsrooms figured out they needed to mimic what was happening in society so they wouldn’t end up on the wrong side of history.” – Mapula Nkosi, editor of the Daily Sun

Coming up the ladder

In 1994, the same year Nelson Mandela took the oath as South Africa’s first Black president, an ambitious young reporter named Mapula Nkosi walked into the Johannesburg newsroom of the Weekly Mail, which made its name opposing apartheid, to begin her career as a cadet reporter.

When she looked up the ranks, she says, she saw only men. But all around her, the country had a new buzzword: transformation. The process was often fuzzy, but the objective was clear: The structures that ruled the country should look more like the people who lived in it.

“Those newsrooms figured out they needed to mimic what was happening in society so they wouldn’t end up on the wrong side of history,” says Ms. Nkosi, now the editor of the Daily Sun, the country’s most-circulated daily newspaper. “The whole time I was coming up I had people on one side of me saying, ‘We don’t understand why you’re in this position,’ and people on the other side saying, ‘We are so excited to see where you go.’”

Those competing forces followed many of South Africa’s women journalists through their rise. Each time they pulled themselves up another rung on the ladder, they heard whispers – that they only got this job because leadership wanted a woman, that they’d never make it.

But when they did, the conversation changed.

“When you do well, you become almost genderless,” says Paula Fray, a media consultant and the first woman to edit the Saturday Star, a major South African newspaper. “But if you don’t do well, then your failings represent your whole gender.”

Meanwhile, women leaders in the newsroom “carry the added responsibility of making these environments more welcoming for women,” says Mary Papayya, a veteran journalist and editor who now sits on the board of the South African Broadcasting Corp. That, she notes, is a particularly difficult task at a time when many outlets have seen their budgets slashed and are now contending with a pandemic that has made news reporting both more dangerous and less lucrative.

And the fight for change goes beyond who sits in the corner office. In South Africa, like many countries, men are disproportionately both the experts and subjects of news stories. A recent analysis of the South African media’s coverage of the COVID-19 pandemic by the organization Media Monitoring Africa, for instance, found that 80% of those quoted in stories about the virus were men.

Ms. Mahlase, the radio news editor, says she sees these kinds of statistics through a new prism since she gave birth seven months ago to her first child, a boy. 

“I want my son to grow up in a world where he has female bosses,” she says. “I want him to grow up listening to women experts on the radio, hearing them as contributors to changing the world and not just as victims of an unfair system.”

Trump Administration Penalizes Chinese Officials for Hong Kong Crackdown

Published

on

WASHINGTON — The Trump administration on Friday imposed sanctions on 11 senior Chinese Communist Party officials and their Hong Kong allies, including chief executive Carrie Lam, over their role in cracking down on political dissent in the southern Chinese territory.

These are the first sanctions against officials from China and Hong Kong over suppression of pro-democracy protests and dissent in the territory. They are being imposed as actions following an executive order President Trump signed last month seeking to punish China for its repression in Hong Kong.

“The United States stands with the people of Hong Kong and we will use our tools and authorities to target those undermining their autonomy,” Steven T. Mnuchin, the Treasury secretary, said in a statement.

The action is another in a series of measures the Trump administration has taken in recent months to ratchet up pressure on Beijing. Last month, the administration imposed sanctions on the Chinese government, including a senior member of the Communist Party, over human rights abuses against the largely Muslim Uighur minority.

Beijing announced in June that it was imposing a new national security law in Hong Kong to grant security agencies expansive powers to crack down on dissent.

Since then, American officials have debated how to get Beijing to roll back the law or how to penalize the action.

Last month, Mr. Trump signed an executive order ending the special status that the United States grants Hong Kong in diplomatic and trade relations, saying Hong Kong was no longer an autonomous entity, and officials are now beginning to treat the territory like mainland China.

Some administration officials had wanted Mr. Trump to announce during the signing that his government was imposing sanctions on Ms. Lam and other officials in China and Hong Kong. The president declined to do so then.

The current flurry of actions against China dovetails with a core part of Mr. Trump’s campaign strategy. His campaign aides are trying to show Mr. Trump is hitting China hard in order to shift the national conversation from his failures on managing the coronavirus pandemic and the economy.

The initial virus outbreak began in central China, and Mr. Trump has blamed Chinese officials for failing to contain it, though he also praised China’s leader, Xi Jinping, for efforts this winter.

Some of the administration’s China hawks are trying to set the two nations on a course for long-term confrontation and ensure that relations remain in a state of open rivalry even if Democratic candidate Joseph R. Biden Jr. wins the November election.
