| North America includes Canada, the United States, Mexico, and the islands of the Caribbean Sea, and is sometimes defined to include the countries of Central America. It is believed that Native Americans, the continent’s first inhabitants, arrived 15,000 years ago, traveling by foot over the Bering Strait, which was a land mass at the time. Following their prey, the Native Americans came to North America and settled principally in the region of present-day Mexico and Central America. European settlers did not arrive on the continent until the late 15th and early 16th centuries. |
