From where did the first Alaskans cross to reach Alaska?

• A. From Africa
• B. From Asia
• C. From Europe
• D. From Australia

Answer: (B)

Migration into Alaska began with people coming from Asia, crossing the Bering Land Bridge that connected Siberia to Alaska during the Ice Age. When sea levels were lower, a broad stretch of exposed land allowed hunter-gatherers to move from Asia into the American Arctic. Over time, these populations spread south and east, forming the ancestors of Alaska Native groups. Archaeological finds and genetic evidence both point to Siberia as the source of the first inhabitants, making Asia the correct origin. The other regions—Africa, Europe, and Australia—were not connected to Alaska by land during that period, so they aren’t the source of the earliest migrations.
