The focus was on the Sahara and the significant (and massive) climate change it has undergone over the last ten thousand years. From lush garden to harsh desert would about sum it up. This is thought to have been due to shifts in the Earth's orbit (according to the show).

This is a long enough period for there to have been a significant selection effect going on for those willing to see the bad times coming and develop genes & memes involved in promoting tribal (religious) mindsets and to drive acquisition of resources (wars) based on those.
