New techniques have shown that people reached the New World far earlier than the long-standing estimate of 13,000 years ago, but scientists still debate exactly when humans arrived on the continent—and how.
Diverse lines of evidence point to humans’ presence in the New World long before the dawn of Clovis culture. But rewriting this chapter of human history raises many questions about how these early people came to inhabit these continents.
While questions still outnumber answers, new findings from archaeology, genetics, and other disciplines are revealing surprising insights into the early cultures of the most recently populated continent.
Genetic evidence points to individuals from South America having possibly floated on a raft to Polynesian islands about 500 years before Europeans navigated there.
The company behind a now-discredited study on hydroxychloroquine also posted a report that has been cited by Latin American governments recommending ivermectin as a possible coronavirus treatment. Clinicians there say the effects have been extremely damaging.
As the afternoon breezes blow harder in the Atacama Desert—a place so desolate it’s used as a model of Mars—more microbes move into its driest regions.
Genetic information from dozens of individuals living 700 to 10,000 years ago reveals connections between Clovis and Native Americans and South Americans.
