Stone tools in India suggest earlier human exit from Africa

Just a week after scientists reported evidence that our species left Africa earlier than we thought, another discovery is suggesting the date might be pushed back further.

Homo sapiens arose in Africa at least 300,000 years ago and left to colonize the globe. Scientists think there were several dispersals from Africa, not all equally successful. Last week's report of a human jaw showed some members of our species had reached Israel by 177,000 to 194,000 years ago.

Now comes a discovery in India of stone tools, showing a style that has been associated elsewhere with our species. They were fashioned from 385,000 years ago to 172,000 years ago, showing evidence of continuity and development over that time. That starting point is a lot earlier than scientists generally think Homo sapiens left Africa.

This tool style has also been attributed to Neanderthals and possibly other species. So it's impossible to say whether the tools were made by Homo sapiens or some evolutionary cousin, say researchers who reported the finding Wednesday in the journal Nature .

"We are very cautious on this point" because no human fossils were found with the tools, several authors added in a statement.

It's not clear how much the tool development reflects arrival of populations or ideas from outside India, versus being more of a local development, said one author, Shanti Pappu of the Sharma Centre for Heritage Education in Chennai, India.

The tool-making style was a change from older stone tools found at the site, featuring a shift to smaller flakes, for example.

Michael Petraglia, an archaeologist who specializes in human evolution in Asia but didn't participate in the work, said he did not think the tools show that our species had left Africa so long ago.

"I simply don't buy it," said Petraglia of the Max Planck Institute for the Science of Human History in Jena, Germany.

Instead, he said, he believes one of our evolutionary cousins in India developed the tool style independently of outside influence. The tools at the site northwest of Chennai in southeastern India are closely related to the older tool-making style there and seem to represent a transition, he said.

The idea that they reflect knowledge brought in from elsewhere would be tough to prove in India, he said. The country has few well-studied archaeological sites and only one fossil find from this period, from a forerunner of Homo sapiens that was associated with the earlier style of tool-making, Petraglia said.

Indians vote in the first phase of the world's largest election as Modi seeks a third term

NEW DELHI (AP) — Millions of Indians began voting Friday in a six-week election that's a referendum on Narendra Modi, the populist prime minister who has championed an assertive brand of Hindu nationalist politics and is seeking a rare third term as the country's leader.

The voters began queuing up at polling stations hours before they were allowed in at 7 a.m. in the first 21 states to hold votes, from the Himalayan mountains to the tropical Andaman Islands. Nearly 970 million voters — more than 10% of the world’s population — will elect 543 members to the lower house of Parliament for five years during the staggered elections that run until June 1. The votes will be counted on June 4.

This election is seen as one of the most consequential in India’s history and will test the limits of Modi's political dominance.

If Modi wins, he’ll be only the second Indian leader to retain power for a third term, after Jawaharlal Nehru, the country’s first prime minister.

Most polls predict a win for Modi and his Hindu nationalist Bharatiya Janata Party, who are up against a broad opposition alliance led by the Indian National Congress and powerful regional parties.

It's not clear who will lead India if the opposition alliance, called INDIA, wins the election. Its more than 20 parties have not put forward a candidate yet.

The BJP controls much of India's Hindi-speaking northern and central parts, but is now trying to gain a foothold in the east and south. Their toughest challenge is in the southern Tamil Nadu state, with 39 seats, and where voting is being held on Friday.

Voters in hot and humid Chennai, the state's capital, began briskly filling the city's nearly 4,000 polling booths. A number of them said they were voting for a change in federal government given rising prices, unemployment and religious polarization stoked by the BJP.

“First thing I came to vote for is to have a country without any religious disharmony. In Tamil Nadu — Hindus, Muslims, Christians, we're all together. And this unity should grow," said Mary Das, a 65-year-old, who was waiting to vote.

P. Chidambaram, an opposition Congress party leader and the country’s former finance minister, said that the people of Tamil Nadu would not vote for the BJP as “it is imposing one language, one culture, one system and one kind of food.”

The BJP has long struggled to capture votes in the state, where two powerful regional parties -- the Dravida Munnetra Kazhagam and All India Anna Dravida Munnetra Kazhagam — dominate. The BJP drew a blank in 2019, and won one seat in 2014.

Voting is also taking place in the northeastern state of Manipur, where a near-civil war for a year has triggered ethnic violence. Mobs have rampaged through villages and torched houses, while more than 150 people have been killed.

The election comes after a decade of Modi's leadership, during which the BJP has consolidated power through a combination of Hindu-first politics and economic development.

Modi has ratcheted up Hindu nationalist rhetoric on the campaign trail, and has sought to present himself as a global leader. His ministers tout him as the steward of a surging India, while his supporters celebrate his campaign promise to make India a developed nation by 2047, when it marks 100 years of independence.

But while India’s economy is among the world’s fastest-growing, many of its people face growing economic distress. The opposition alliance is hoping to tap into this, seeking to galvanize voters on issues like high unemployment, inflation, corruption and low agricultural prices that have driven two years of farmers' protests.

The opposition, and critics, also warn that Modi has turned increasingly illiberal. They accuse Modi of using tax authorities and the police to harass the opposition, and fear that a third term could undermine India's democracy. His Hindu nationalist politics, they argue, has bred intolerance and threatens the country's secular roots.

“Modi has a very authoritarian mindset. He doesn't believe in democracy. He doesn't believe in Parliamentarianism,” said Christophe Jaffrelot, a political scientist who has written about Modi and the Hindu right.

Modi insists that India's commitment to democracy is unchanged. He told a Summit for Democracy meeting in New Delhi in March that '"India is not only fulfilling the aspirations of its 1.4 billion people, but is also providing hope to the world that democracy delivers and empowers.’’

The Indian leader, who enjoys vast popularity among India's 1.4 billion people, is targeting a two-thirds majority this time.

The BJP hopes for a landslide win powered by its popular welfare programs, which it says have improved access to clean toilets, health care and cooking gas, as well as providing free grain to the poor. Moves like the construction of a controversial temple to Ram on the site of a demolished mosque, and the scrapping of the disputed Muslim-majority region of Kashmir's former autonomy, may resonate with supporters who hail him as the champion of the Hindu majority.

“Any party that comes back for a third term, and with a brute majority, is a scary prospect for democracy,” said Arati Jerath, a political commentator.

Modi's two terms have seen civil liberties in India come under attack and it implementing what critics say are discriminatory policies. Peaceful protests have been crushed with force. A once free and diverse press is threatened, violence is on the rise against the Muslim minority, and government agencies have arrested opposition politicians in alleged corruption cases.

The BJP has denied its policies are discriminatory and says its work benefits all Indians.
