Researchers from the University of Cambridge are using "palaeo-inspired robotics" to study how ancient fish transitioned from swimming to walking roughly 390 million years ago. By creating robotic analogues of ancient fish skeletons, the team aims to explore how the pectoral and pelvic fins evolved to support weight on land. These robotic models will help fill in gaps left by incomplete fossil records, providing new insights into the biomechanics of early land vertebrates.
