A retention of the lineages suggested by Pasteur (1964) are feasible but distinguishing characters difficult to define. Should this approach be upheld, the relationships would follow those sug- gested in fig. 6. All species with the exception of L. rex and to a lesser extent L. methueni are rupicolous indicating a common ancestry and distinct from the remainder of Lygodactylus species. These are all arboreal although many species are found on the walls of houses and even on rocks away from trees. The transition to a rupicolous way of life is of considerable significance and possibly relates to a paucity of trees as the ancestral stock moved south. Pasteur (1964) mentions in this context an adaptive zone which according to Simpson (1953) refers to a way of hfe and not a place where life is led. This adaptive zone must have been along the eastern escarpment of Africa which experienced considerable climatic. Fig. 6: Evolution of the Austro-Oriental phylum (adapted from Pasteur 1964)..
