It has been suggested that character displacement with regard to the structure of the trophic apparatus of Paranthropus and Homo occured during the early Pleistocene in Africa, and that this displacement was instrumental into pushing H. transvalensis into the "human niche." The data available, though not as extensive as one would wish, appear to support this hypothesis, which was first advanced in a different form by Brown in 1958. Predictions are made with reference to the results of future excavations that will test the validity of the hypothesis proposed.
