Niède Guidon Scientist
Niède Guidon (Portuguese pronunciation: [niˈɛdʒi ɡiˈdõ]) is a Brazilian archaeologist who was born on the 12 March 1933 in Jaú, in the state of São Paulo, Brazil. She has won international recognition and support for her struggle to protect Brazil's rich archaeological heritage. Since the late 20th century, she has excavated hundreds of prehistoric sites in Piauí, Brazil. Her dating of findings indicates that human settlement preceded the earliest known in North America by tens of thousands of years, which has generated controversy. In addition, she has theorized that some of the early ancient peoples may have arrived from across the Atlantic, rather than over the land bridge from northeast Asia.
