RE:East Africa

Hey deno, when we took world civilization i happened to catch a few things in between naps. That there was already a civilization established much earlier than the Egyptian civilization around east Africa. There is proof that they were the first to domesticate the chicken,whose remains were accurately identified and dated to before the era of the Pyramids, within the area of present day Coast and into Tanzania. It's believed that they had links to the Shanzus who appeared later.
But interestingly,this ancient kingdom fell to a northern force, which totally destroyed any eveidence of its existence. That is why it's not well documented as there is very little in terms of remains.
PS: HAve u wondered why most of the early Egyptian paintings and monuments are black? It's coz they were ruled by blacks, with origins from present day Sudan.but again they fell as a result of a revolt by the middle east inhabitants whom they tolerated.
