i'm not sure of the reliability of the source but it certainly has a lot of interesting information. what stood out was that the rampa pictographic system of west Africa has a symbol that looks identical to the symbol of the Population Connection formerly known as Zero Population Growth (non profit based in D.C.)

source:Phoenicia.org

symbol:

kooh cuuh ½afku, God [behind] unborn fetus, pregnant (104sf)

With the Saafi, the infant not yet born is only a spirit. This mark symbolizes the descent of a spirit come to assist in the death. When one sees this mark on a head of cattle, one knows that it belongs to a motherless orphan in the Saafi family.
