Noodle Bodies, Gyroscope Ears, and Phantom Girdles - Limb Reduced Lizards

Explore the fascinating evolutionary transformations of squamate reptiles in this 48-minute lecture that examines how lizards have independently evolved snake-like, limb-reduced body forms multiple times throughout their evolutionary history. Discover the dramatic skeletal modifications that enable these body plan changes through modern imaging techniques that reveal normally hidden internal anatomy. Learn about the surprising consequences of limb reduction on other skeletal structures, including skulls and girdles, with particular focus on skinks - one of the most diverse lizard groups that has successfully evolved limb-reduced forms over 50 times across different lineages. Gain insights into how these anatomical changes correlate with habitat adaptations and functional requirements, presented by Dr. Marco Camaiti, an evolutionary biologist specializing in vertebrate anatomy and morphology who studied limb-reduced body shape evolution during his PhD research and currently works as a postdoctoral researcher at London's Natural History Museum.
