More than 150000 years ago, beings morphologically identical with the man of today were living in the region of the great lakes at the sources of the Nile and nowhere else. This notion, and others which it would take too long to recapitulate here, form the substance of the last report presented by the late Dr Leakey at the Seventh Pan-African Congress of Pre-History in Addis Ababa in 1971. It means that the whole human race had its origin, just as the ancients had guessed, at the foot of the Mountains of the Moon. Against all expectations and in defiance of recent hypotheses it was from this place that humans moved out to people the rest of the world. From this two facts of capital importance result:
a) of necessity the earliest humans 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;
(b) there were only two routes available by which these early humans could move out to people the other continents, namely, the Sahara and the Nile valley.
