Hundreds of millions of years ago, North America was part of a larger ancient supercontinent named Laurasia. A few million years ago, a new land bridge arose and connected North America to South America. Beringia connected North America to Siberia a few times during ice ages in the past 20,000 years. North America has a population of 527 million and is the 4th most populous continent in the world.
