Question 21

Scientists studying land masses and climate know that the Pleistocene Ice Age created a land bridge that connected
Asia and North America (Alaska) over 13,000 years ago. A widely accepted migration theory is that

Question 23

The theory that the savannah was expanding due to increasingly arid conditions, which then drove
hominin adaptation. It suggests that early hominids were more suited to
dry climates and evolved as the Africa‟s dry
savannah regions expanded.

Answer 23

Aridity Hypothesis
