By necessity, the earliest people were ethnically homogeneous and Negroid. Gloger's Law, which would also appear to be applicable to human beings, lays it down that warm-blooded animals evolving in a warm humid climate will secrete a black pigment (eumelanin). Hence, if mankind originated in the tropics around the latitude of the great lakes, he was bound to have brown pigmentation from the start and it was by differentiation in other climates that the original stock later split into different races.
According to Cheikh Anta Diop, "the color black acts as a protection of the organism. If man was first born in Africa and had not been black, he would not have survived. We know scientifically, that ultra-violet rays would have destroyed the human organism in the equatorial regions, if the organism had not been protected by black pigmentation, that is Melanin. That is obviously why man, first born in Africa was black. It is not something we need to be proud of, it is simply a fact."
The oldest known fossil remains, according to Dr. Louis Leakey, were found in the Olduvai Gorge region in Kenya, Uganda and Tanzania. These first "small" people were known as the "Twa", who worshipped the God Bes, a primitive human form of Horus I, being the earliest form of Ptahthe God of Gods.
We also find this same black God, Ptah, symbolized in the mystery system in Egypt. The Twa are said to have migrated the four thousand one hundred miles of the Nile river, establishing what was later to become the Egyptian civilization.
According to Manetho, the first dynasty was established by Menes (or Narmer), about 5500 B.C., when Menes conquered Lower Egypt, combining both Upper and Lower Egypt. This alliance of the red and white crowns of the two countries were joined, and Menes inherited the double diadem, becoming the first Pharaoh of the world.
