ABSTRACT
In previous publications the author has shown that we cannot refer simply to linguistic data, nor to human biological data alone, in order objectively to explain the ethnic bases of primitive social formations in interlacustrine Africa in general and Rwanda in particular (Twagiramutara 1980a, b). In this chapter, and through an examination of several studies, we ask whether ethno-archaeological information can be useful in our quest. We direct discussion to the interrelations which, over a period of time, have arisen between ecological, economic, and cultural phenomena. We also consider the possible effect of such interrelations upon the emergence and development of the socio-ethnic categories under consideration.
