Asia and North America are now separated by a part of the Pacific Ocean called the Bering Strait. A strait is a narrow pathway of water connecting two larger bodies of water. Two million and 12,000 years ago, the Bering Strait did not exist. Instead, plains of grass and land connected the two continents. Before this time, people and animals could cross this plain from Asia to North America on their feet. People who went across the land bridge from Asia hunted giant moose, antelope, and mammoths. When the animals wandered across the land bridge to North America, some of the hunters moved there too. This meant that the Bering Strait stopped hunters, making it more safe! Slowly, hunters made their way southward across North America. Soon when they finally reach many different areas of the continent, among these people were the first Californians. They settled in all of California's regions-in it’s northern mountains, in its river valleys, along the coast, and in dry areas on the southwest.
The main advantages are underlined.
