%0 Journal Article %T Estimating rates and patterns of morphological evolution from phylogenies: lessons in limb lability from Australian Lerista lizards %A Wiens John J %J Journal of Biology %D 2009 %I %R 10.1186/jbiol112 %X Squamates (lizards and snakes) offer an exciting model system for research on the evolution of body form. A new phylogenetic study in BMC Evolutionary Biology of Australian lizards shows remarkable evolutionary lability in digit numbers among closely related species, but also highlights important challenges in this area. %U http://jbiol.com/content/8/2/19
