A study shows that the earliest human inhabitants of Moxos plains began transforming the tropical savanna eco-region in Bolivia 10,000 years ago, that is 8,000 earlier than previously thought.
The study was conducted by scientists from Bern in cooperation with universities in Britain, Spain and the United States.
The study involved an unprecedented large-scale regional analysis of more than 60 archaeological sites, according to the university statement.
Samples were retrieved from 30 forest islands and archaeological excavations were carried out in four of them.
“Until this recent study, scientists had neither searched for, nor excavated, old archaeological sites in this region that might document the pre-Columbian domestication of these globally important crops,” says Umberto Lombardo from Bern university.
