Fig. 1. A cladogram showing the relationships between the species from this study based on Jackman et al. (1999) and T. R. Jackman (personal communication). The lengths of the arms of the cladogram have no quantitative meaning, although we have linked closely related species with short arms. There are other species between those listed in this cladogram: i.e. the closest taxa in this diagram are not necessarily the most closely related species known. Jackman et al. (1999) identified 17 major distinct clades within the genus Anolis. Five of these, plus the closely related outgroup genus Polychrus, are represented in our sample. ^*A. sagrei and A. equestris were collected from feral populations in Florida, but are Cuban in origin.
