Paleolithic evidence of human activity in Uganda goes back to at least 50,000 years, and perhaps as far as 100,000 years, as shown by the Acheulean stone tools recovered from the former environs of Lake Victoria, which were exposed along the Kagera River valley, chiefly around Nsonezi [REF].
The cultivators who gradually cleared the forest were probably Bantu speaking people, whose slow but inexorable expansion gradually took over most of Africa south of the Sahara Desert.
