Step 1
Identify the migration route
Answer
The migration route from East Africa involves three primary locations: A is the starting point in East Africa, B represents a significant stop in Asia or Europe, and C indicates a location in the Americas. The path can be traced across these points, indicating a pathway taken by early humans.

At location B, genetic studies have provided evidence of migration patterns tracing back to populations in East Africa. At locations C and D, fossil evidence supports the movement of populations as they settled in the Americas.
