Based on the exploration of archaeological sites in Piaui — which uncovered 15,000-year-old human bones, cave paintings estimated to be around 35,000 years old and evidence of fires dating back 48,000 years — Guidon argued that humans had arrived on the American continent from Africa via the sea, and much earlier than previously believed, the statement said.The Chico Mendes Institute for Biodiversity Conservation and the National Institute of Historical and Artistic Heritage commended Guidon’s contributions in a joint statement Wednesday.

“If Serra da Capivara is today recognized as one of the most important concentrations of archaeological sites in the world, with a profound impact on the debate and understanding of the history of human occupation of the Americas, it is above all thanks to Niède Guidon’s vision and tireless defense of science and culture,” they said.“Professor Niède is one of those unforgettable figures who have inscribed their name in our history,” Mauro Pires, president of the Chico Mendes Institute, was quoted as saying, describing her contribution to global archaeology as immeasurable.“Brazilian science is saddened by the passing of Niède Guidon, who helped us understand the origins of man in the American continent,” Brazil’s

said in a statement.Guidon was born in the interior of Sao Paulo state in 1933. She graduated in Natural History from the University of Sao Paulo in 1959, before moving to France to pursue her studies. She completed her doctorate at Paris’ Sorbonne University in 1975, after presenting a thesis on the cave paintings in Piaui state.

Guidon went on to found the Foundation Museum of the American Man, a non-profit dedicated to the cultural and natural heritage of Serra da Capivara National Park, which she led between 1986 and 2019.

“For decades, she and her team fought to secure funding and infrastructure for the park, firmly standing against government neglect,” the nonprofit said on Wednesday, adding that her work was marked by “passion, persistence, and a generous vision of science as a tool for social transformation.”Here’s what else we know.

Trump says it’s all about protecting U.S. industries. He reiterated that argument on Friday, when he first announced the 50% tariff on imported steel during a visit with steelworkers in Pennsylvania, where he also discussed aat U.S. Steel’s Mon Valley Works–Irvin Plant in suburban Pittsburgh, Trump said that the tariff hike would “further secure the steel industry in the U.S.” Shortly after, he took the same tone when sharing plans to also raise tariffs on imported aluminum.

In Tuesday’s proclamation, Trump also said that the higher tariffs would ensure that imported steel and aluminum would “not threaten to impair the national security.”“In my judgment, the increased tariffs will more effectively counter foreign countries that continue to offload low-priced, excess steel and aluminum in the United States,” he said in the proclamation.
