It believed that the first humans to settle in the Americas were from Asia and arrived anywhere between 42,000 to 17,000 years ago. Norse explorer Leif Erikson was the first European settler in the Americas; however, Christopher’s Columbus’s voyages were the first to result in permanent colonization.
North America and South America meet at a point on the Isthmus of Panama. Panama was originally part of South America when the boundary between the continents was set as the Costa Rican border and Panama was a province of Colombia. The border changed in 1903 when Panama gained its independence. Panama is the only country to have changed continents.
The total area of the Americas is 16.43 million square miles (42.55 million square kilometers) making up about 8% of Earth’s total surface and 28.4% of the Earth’s total land surface. Between both continents, there are about 1.002 billion people, two-thirds of whom live in the United States, Brazil, and Mexico.
Between the two continents, there are 31 countries and dozens of territories belonging to the United States and several European countries including the United Kingdom, France, Norway, the Netherlands, and Denmark.
