1. The First Civilizations of the Americas
What is culture?
How would you react to a people whose appearance and language are unlike anything you’ve ever known?
What can happen when one culture imposes its values on another?

Groups of hunters tracked herds of animals across this land bridge

Adapting to New Conditions
As the ice age ended, temperatures rose and people had to adapt to new conditions.

About 5,000 years ago, people in Central America learned to grow crops and agriculture began to grow.
Instead of migrating, people began to stay in one place.
