    Migration into the continents

    The specifics of Paleo-Indian migration to and throughout the Americas, including the exact dates and routes traveled, are subject to ongoing research and discussion. The traditional theory has been that these early migrants moved into the Beringia land bridge between eastern Siberia and present-day Alaska around 40,000 – 17,000 years ago, when sea levels were significantly lowered due to the Quaternary glaciation. These people are believed to have followed herds of now-extinct Pleistocene me...

    South America

    In the 1960s and 1970s, the governments of Argentina, Brazil, Chile, and Uruguay were overthrown or displaced by U.S.-aligned military dictatorships.
