BIPEDALISM MODEL EVALUATOR		Home
Evaluative Framework
4 "Epistemological"
4.2 Complimentary	There are a wide variety of ideas which have been suggested to explain the origins of hominid bipedalism. So diverse are the ideas that it has often been suggested that several, if not all, of them must have been working in concert. The specific question of model compatibility, however, seems not to have been systematically considered in the literature to date. Here, a model is judged better the more compatible it is with others. The multi-factorial model was, not surprisingly, judged the most compatible model here. None were especially incompatible with the others.
