According to the map, how did people first arrive in North America?

I assume your map shows people crossing the Bering Strait (or land bridge) from northeastern Asia into northwestern North America.

To determine how people first arrived in North America according to a map, we need to follow a few steps:

1. Find a map specifically representing the time period and context in which the first human arrivals in North America occurred. The most relevant maps would usually display the migration routes and historical information of early human populations.

2. Identify the geographical regions or entry points on the map that indicate the initial arrival of people in North America. This might include areas such as Bering Strait, coastal regions, or inland routes.

3. Trace the migration routes depicted on the map to understand the various paths taken by early humans in reaching North America. This could involve following lines, arrows, or routes marked on the map, focusing on the relevant time period.

4. Pay attention to any additional information provided on the map, such as migration dates, archaeological sites, or key landmarks associated with the arrival of humans in North America.

By going through these steps, you should be able to examine the map and gather information on how people first arrived in North America.

I don't assume anything about a map I can't see. What does it show, Alexa?
