John Engelman: Agriculture and civilization select a race for intelligence. Caucasians began agriculture about eleven thousand years ago. We began civilization about five thousand years ago. Negroes only adopted agriculture about four thousand years ago. They never developed their own civilizations. They have only recently been exposed to White civilization.
Agriculture was probably developed by Africans before it was developed by anyone else. There is evidence for agriculture or pre-agriculture in Africa (West African Guinea Highlands) as early as 12,000 YBP. You must realize that Africans originated many things that we as humans do.
The next to develop agriculture were the Mayans (corn), the Chinese (rice), and the Papuans (yams), all at 9,000 YBP. The Egyptians and Mesopotamians were not far behind. Africans even had plantation agriculture as early as 900 CE in Tanzania. I doubt if Caucasians developed agriculture 11,000 YBP. Are we referring to Mesopotamia, the Levant, or Egypt here?
Animal husbandry was also developed very early on in Africa. It may have been developed in the Western Sahara before anywhere else on Earth. A figure of 9,000 YBP is suggested for animal husbandry in the Sahara. However, pigs may have been domesticated in Papua around this time also. Animal husbandry was widespread in Africa, particularly in the Sahara, the Sahel and Ethiopia, on contact. I don’t know much about animal husbandry further south, but I have heard there was a shortage of animals to domesticate.
At any rate, the invention of the hoe and subsequent hoe agriculture along with the spear played a major role in the history of Africa. Both derived from the early development of metallurgy in the form or iron. Indeed, the Iron Age came to Africa before it came to Europe. The development of iron metallurgy and the subsequent creation of those two iron tools allowed the Bantus to expand massively all over Central and South Africa in only the last 2-3,000 years.
Africans definitely had civilizations, that’s for sure. Mostly in West Africa but quite a few in the Sahel too. There was even a civilization in Rhodesia. Early European explorers drew drawings of large African cities. Looks like civilization to me. Civilizations were especially common in Nigeria. They had manufacture, trade, agriculture for export, all sorts of things.
