What caused the Nomadic Hunter-Gatherers to come to America?

The correct choice highlights the significant role of animal migration in the lives of Nomadic Hunter-Gatherers. These groups migrated to America primarily to follow herds of animals, which were essential for their food supply. As these animals moved across landscapes in search of food and water, the hunter-gatherers followed, adapting their lifestyle to the seasonal migrations of the herds.

This mobility allowed them to utilize the resources offered by different environments and seasons, ensuring a steady supply of the game necessary for their survival. The movement of these populations is linked to the changing climate and land bridge connections, which facilitated the migration process from Asia into North America.

While some of the other options present plausible reasons for migration, such as seeking new resources or escaping conflicts, the primary motivation for nomadic hunter-gatherers was closely tied to the availability and movement of animals, making it essential for their subsistence strategies.
