About

Patrick Arnold is a paleontologist and biomechanist whose research bridges the gap between extinct vertebrates and modern locomotion. His most cited work, "Reverse-engineering the locomotion of a stem amniote" (2019, 226 citations), exemplifies his innovative approach: using computational modeling and fossil data to reconstruct how early tetrapods moved on land. Arnold’s major contributions lie in deciphering the evolutionary transition from aquatic to terrestrial locomotion, particularly in stem amniotes—the ancestors of reptiles, birds, and mammals. By integrating biomechanics, paleontology, and robotics, he has provided quantitative insights into how ancient animals walked, revealing the constraints and adaptations that shaped early terrestrial movement. His work has been widely cited for its methodological rigor and its ability to test long-standing hypotheses about the evolution of gait. Beyond this landmark paper, Arnold’s research continues to influence fields from functional morphology to evolutionary robotics, making him a key figure in understanding the origins of vertebrate locomotion.
