>>2545951Alright, fine, then it could have happened earlier in the late neolithic before written history developed. The midwestern savannah that OP posted was partially created by the Indians systematically burning vegetation to open habitat for deer, elk, and bison. It's no stretch to say that North African neolithic people managed herds in a similar way, enough to make their population explode and help drive climate change. Egypt may have emerged as a river civilization after the rest of the land became unusable.
North Africa had thriving stone traditions similar to North American ones, namely the Oranian and Capsian traditions. This implies a society adept at hunting/herding large critters.
You can't explain why I'm retarded tho. All you can manage is a knee-jerk response to something that rustles your jimmies. Because I'm right and you know it.
