How did early humans overcome the world’s most difficult terrain and ultimately dominate the planet?

Through their resourcefulness, teamwork, creativity, and cognitive abilities.

Explanation:

The movie Great Human Odyssey offers an insight into how early humans were able to survive the difficult terrain of the ancient world and ultimately dominate the planet. Before people spread across the world, man resided in Africa. The migration from Africa to other parts of the world involved crossing the Sahara desert, surviving freezing colds in the arctics, and even passing through large bodies of water.

Application of their cognitive abilities as well creativity helped the migrants and an example of this is the Ancient Polynesians who were able to migrate to the America's by observing the stars and currents.

Observing present cultures of people today also gives an insight into how the ancestors must have survived in their times. Crude tools and crafts from archaeological findings illustrate their resourcefulness which helped them survive.
