Vestigial skeletal structures in four snake species and five species of dibamid and scincid lizards

Ryshonda Patrice Lewis, Fayetteville State University

Abstract

Vestigial structures or organs are classified as those that have evolved over time to become rudiments of their ancestral forms and in many occurrences are non-functional for their original, ancestral use. The study of vestigial structures across animal species is crucial in the gathering of evidence that supports the theory of evolution. In this study I identify any vestiges of the hind limbs, pelvic girdle, forelimbs, and pectoral girdle of four snake species and five species of dibamid and scincid lizards. To aid in identification of the vestiges found in the specimens examined, I considered the normal morphology of the typical reptilian pectoral girdle, pelvic girdle, forelimbs, and hind limbs lizard species.
