Answer:
"Africa's Diverse climatic zones."
Explanation:
The reason is because it is showing a climate map, meaning the "Origin of Humankind" and "A mosaic of Cultures" are already incorrect. Once you look at the map you'll see that its mostly not desert, but a mix of many climates from Mediterrean /Drylands climate in the north to the Mountains of Ethiopia. So it cancels out "Africa's unique desert regions" Leaving you with "Diverse climatic zones."
