What is the most likely reason the first people crossed from Asia to America?

• A. To escape drought
• B. To spread religion
• C. Probably for food
• D. To find gold

Answer: (C)

Subsistence and following food resources drive early migration. During the last Ice Age, cooler climate conditions pushed herds of large animals like mammoths and bison across the land bridge that connected Siberia to Alaska. Lower sea levels exposed this corridor, making a feasible overland path for small hunter-gatherer groups. They moved in search of fresh hunting grounds and edible plants, gradually spreading southward into the Americas as resources allowed. The other options aren’t as plausible for the first migrations: escaping drought might be a factor in some movements, but subsistence—finding food—best explains the initial crossing, and religion or gold were not typical motivators for the earliest peopling of the continents.
