There is a reason white people cant try on a zebra what they do on a horse. Small cats, cattle, camels, sheep, goats, and elephants were domesticated. Hannibal took elephants into Rome.
Yeah, the reason we can't use zebras like horses is that blacks never put in the work to domesticate them. It takes hundreds and thousands of years of breeding, after all. We did it, blacks didn't.
Cats, cattle, camels, sheep, goats, and elephants were not domesticated by sub-Saharan Africans. Phoenicians and Northern African Arabs and Egyptians did that. Arabs have the best horses on Earth, and racing camels, unpromising for use as camels are --- dreadful animals, but Arabs did domesticate them. Blacks didn't domesticate any of them. Blacks remained in the Stone Age --- literally, using stone axes --- until the mid-20th, when we pushed some cultural improvement on them. But not much took.
