During the last decades the study of functional morphology received more attention incorporating more detailed data corresponding to the internal anatomy that together contribute for a better understanding of the functional basis in locomotion.Here we focus on 2 lizard families,Tropiduridae and Liolaemidae,and use information re­lated to muscle-tendinous and external morphology traits of hind legs.We investigate whether the value of the traits analyzed tend to exhibit a reduced phenotypic variation produced by stabilizing selection,and whether species showing specialization in their habitat use will also exhibit special morphological features related to it.As a result,we identified that evolution of hind limb traits is mainly explained by the Ornstein-Uhlenbeck mod­el,suggesting stabilizing selection.Liolaemids and tropidurids show clear ecomorphological trends in the vari­ables considered,with sand lizards presenting the most specialized morphological traits.Some ecomorphologi­cal trends differ between the 2 lineages,and traits of internal morphology tend to be more flexible than those of external morphology,restricting the ability to identify ecomorphs shared between these 2 lineages.Conservative traits of external morphology likely explain such restriction,as ecomorphs have been historically defined in oth­er lizard clades based on variation of external morphology. 展开更多
