Here are the push and pull factors selected for early human migration along with explanations for each choice:
Push Factors:
-
Diseases
- Explanation: Diseases can significantly impact population survival, leading individuals or groups to leave areas where they can no longer thrive or are facing health threats.
-
Competition for resources
- Explanation: When resources such as food, water, and shelter become scarce due to high population densities, early humans would be compelled to migrate to find more abundant resources.
-
Natural disasters
- Explanation: Events like volcanic eruptions, floods, or droughts can render an area uninhabitable, forcing people to leave in search of safer environments.
Pull Factors:
-
Abundant food and water
- Explanation: The availability of food and clean water would attract early humans to settle in a particular area, encouraging migration toward those lush and resource-rich environments.
-
Little to no competition for resources
- Explanation: Areas with fewer inhabitants or more abundant resources would be appealing for early humans seeking a better chance of survival, thereby pulling them to migrate to those places.
These factors illustrate the dynamic relationship between environmental conditions, resource availability, and human behavior in the context of migration.
