Figure 1. A in The relationship between skull morphology, biting performance and foraging mode in Kalahari lacertid lizards

Figure 1. A, phylogenetic relationships among major lizard clades showing the evolution of foraging mode across squamates. The cladogram is based on Estes, de Queiroz & Gauthier (1988). B, phylogenetic relationships among the taxa included in this study. Sit-and-wait foraging (black bars) is presumed to be the basal condition for both Meroles and Pedioplanis. See text for details. The cladogram is based on Arnold (1991).
