When did humans get to South America? This giant shelled mammal fossil may hold clues toggle caption Daniel Eskridge/Stocktrek Images/Science Source Fossilized bones from an extinct, shelled mammal offer us the latest clue about when humans arrived in South America. If people were present on the continent then, says Alia Lesnek, a geologist at CUNY Queens College who wasn't involved in the study, "it can tell us about the really long history that humans have with climate change" — and their resilience in the face of it. "We realized," he says, "the shape of marks are quite similar to cut marks made experimentally by humans." "So it's one of the oldest evidence of human presence here in South America," Delgado says.
