FIGURE 16. Evolution of habitat usage among Phrynocephalus species and populations including outgroups. Rock habitat is only used by the outgroup Laudakia. Hard substrates are clay, gravel, and dry lakebed. Soft substrates are small sand dune and large sand dune. See table 5 and the methods section for details of habitat categories, and plates I–VIII for images of habitats with species.
