Historical Processes and Genetic Implications of Limb Reduction and Loss in an Island Skink Lineage
… of scincid lizards to possess both fully limbed and limbless species. And yet, nothing is known of the phylogenetic relationships of this exceptional group. Morphologically similar body plans have made it difficult to assess species-level diversity, and the genus has long been recognized …

Phylogeny and evolution of Lerista (Lygosominae, Scincidae, Squamata).
… species possessing well-developed, pentadactyl limbs resemble typical non-fossorial scincids in body proportions, while many other species exhibit varying degrees of limb reduction and body elongation, including two that are highly elongate and entirely limbless. The extensive variation in limb …

A functional morphological study of limb regression in some Southern African species of Scincidae (Reptilia : Sauria)
How and why did limblessness evolve in certain skinks? These questions are explored in certain species of the Scincidae (from southern Africa) that vary in the degree of limb reduction. This regression series consists of Mabuya capensis (with normal, pentadactyle limbs), Riopa sundevallii (with …

Investigating the Patterns of Convergence in Pectoral Girdle Reduction During the Evolution of Limblessness in Lerista (Scincidae)
… groups have evolved a snake-like, elongate, limbless body plan. Studies of the patterns of limb reduction have revealed a close relationship between the reduction of the limbs and body elongation; however, the loss of the skeletal elements that support the limb, the pectoral girdle, has been …
