The Sahara Pump Theory is a hypothesis that explains how flora and fauna migrated between Eurasia and Africa via a Levantine land bridge. The theory observes that African pluvial periods are associated with a "wet Sahara" phase, during which larger lakes and more rivers exist. This causes changes in the type of animals found in the area.

  • The Sahara Pump Theory is a hypothesis that explains how flora and fauna migrated between Eurasia and Africa via a Levantine land bridge. The theory observes that African pluvial periods are associated with a "wet Sahara" phase, during which larger lakes and more rivers exist. This causes changes in the type of animals found in the area. Regardless of the aridity of the greater Sahara, migration along the river corridor was halted when, during a desert phase 1.8-0.8 Ma, the Nile ceased to flow completely and possibly flowed only temporarily in other periods due to Nubian Swell uplift.
