Kevin Padian

Kevin Padian (born 1951) is an American paleontologist and evolutionary biologist. He is Professor of Integrative Biology and Curator of the Museum of Paleontology Emeritus at the University of California, Berkeley, where he taught from 1980 to 2020. Padian's research focuses on vertebrate evolution, especially the origins of flight, the paleobiology of pterosaurs, the emergence of dinosaurs across the Triassic-Jurassic boundary, the evolution of birds from theropod dinosaurs, the growth dynamics of dinosaurs and related fossil reptiles, and the interpretation of fossilized footprints.^[2] He has also focused on the history of evolutionary thought, particularly surrounding the Victorian Age and the European Enlightenment, regarding Transcendentalism and the evolving interpretation of morphology, as well as the emergence of the theory of evolution by Darwin and his contemporaries. Padian has authored and co-authored nearly 150 scientific articles and some 200 reviews, perspectives, and popular articles, and has co-edited and co-written ten books.

Padian received a bachelor’s degree in natural science and a Master of Arts in Teaching from Colgate University. He later earned an M.A. and a Ph.D. in biology from Yale University, where his research focused on the evolution of flight in vertebrates. His work in paleobiology has examined the flight and locomotion of pterosaurs. He proposed that pterosaur wings were not attached to the ankles in a bat-like manner, and that their hip joints and hind limbs functioned more similarly to those of birds and other dinosaurs, consistent with common ancestry. He also argued that pterosaurs were primarily bipedal and lacked anatomical features associated with arboreal locomotion, leading him to infer that powered flight in the group evolved in a terrestrial context.

Padian further hypothesized that pterosaurs originated from small bipedal archosaurs, an idea anticipated in a different form by Friedrich von Huene and later supported by phylogenetic studies, including work by Davide Foffa, Sterling Nesbitt, and colleagues in 2022 and 2023. His interpretations of pterosaur anatomy and posture built on earlier comparative approaches dating back to Georges Cuvier.

Padian joined the University of California, Berkeley, in 1980 as Professor of Integrative Biology and Curator of the Museum of Paleontology, where he taught until 2020. He also served as Research Associate at the Museum of the Rockies, Montana State University (2000–2015).

Padian held numerous roles in the Society of Vertebrate Paleontology from 1983 through 2002. He served on the Romer Prize Committee (1983–1986), was Program Chairman (1984, 1993–1996), chaired the Publications Promotions Committee (1988–1989), and served on the Media Relations Committee (1996–2002). He was also on editorial boards for the Journal of Vertebrate Paleontology, Geology, Paleobiology, Palaeontologia africana, Trends in Ecology and Evolution, and several other journals. He continues as Subject Editor in Organismal and Evolutionary Biology for Royal Society Open Science.

Padian served as President of the National Center for Science Education from 1995 to 2012 and held other board positions starting in 1988. He contributed to K–12 science education, including as a principal author of the 1990 California Science Framework K–12.

Padian's research covers vertebrate evolution, pterosaurs, early birds, dinosaurs, and the history of evolutionary thought.

Padian collaborated with James Cunningham, Wann Langston, and John Conway on studies of the functional morphology of Quetzalcoatlus, the largest known flying animal with a wingspan of 33–35 feet (11–12 m). Their work presented evidence that although Quetzalcoatlus moved quadrupedally on the ground, propulsion came from the hindlimbs, and forelimbs were largely non-weightbearing. This made a quadrupedal launch impossible. During terrestrial progression, the forelimbs were lifted to allow the hindlimbs to stride and lowered after foot placement.
