Thus, warm and hot climates prevail all over Africa but the northern part is the most marked part by aridity and high temperatures.
Why is Africa so hot Quora?

Did We just emerge in eastern Africa?
The hypothesis: No, we did not just emerge in Eastern Africa. As of 300,000 years ago, our ancestors were already spread around the continent (paleoanthropologists have identified a probable Homo sapiens skull in South Africa dating back 250,000 years). And they were on the move, and spreading their genes.
Did modern humans interbreed with archaic hominins in Africa?
In this new view of African multiregionalism, some of these ancient humans may also have interbred with archaic hominins in Africa, separately from encounters with Neanderthals and Denisovans in Eurasia. We characterise modern humans as having small, slender faces, a protruding chin and a rounded skull.
What is the origin of the out of Africa theory?
The Out of Africa theory was bolstered in the early 1990s by research on mitochondrial DNA studies by Allan Wilson and Rebecca Cann which suggested that all humans ultimately descended from one female: Mitochondrial Eve. Today, the vast majority of scholars have accepted…
