The dinosaurian femoral head experienced a morphogenetic shift from torsion to growth along the avian stem (2022)
Journal Article
Hutchinson, J. (2022). The dinosaurian femoral head experienced a morphogenetic shift from torsion to growth along the avian stem. Proceedings of the Royal Society B: Biological Sciences, https://doi.org/10.1098/rspb.2022.0740

"The dinosaurian femoral head experienced a cryptic evolutionary shift in morphogenetic process." The evolution of birds-and their highly derived locomotion-from their terrestrial dinosaurian ancestors has captured scientific interest for generations...

Spherical Frame Projections for Visualizing Joint Range of Motion (2022)
Journal Article
Herbst, E. C., Eberhard, E. A., Richards, C. T., & Hutchinson, J. R. (2022). Spherical Frame Projections for Visualizing Joint Range of Motion. Journal of Experimental Biology, https://doi.org/10.1111/joa.13717

Quantifying joint range of motion (RoM), the reachable poses at a joint, has many applications in research and clinical care. Joint RoM measurements can be used to investigate the link between form and function in extant and extinct animals, to diagn...

Title: The extinct shark Otodus megalodon was a transoceanic super-predator: inferences from 1 3D modelling 2 Short title: Megalodon ecological inferences from new 3D model 3 4 (2022)
Journal Article
Cooper, J. A., Hutchinson, J. R., Bernvi, D. C., Cliff, G., Wilson, R. P., Dicken, M. L., Menzel, J., Wroe, S., Pirlo, J., & Pimiento, C. (2022). Title: The extinct shark Otodus megalodon was a transoceanic super-predator: inferences from 1 3D modelling 2 Short title: Megalodon ecological inferences from new 3D model 3 4. Science Advances, https://doi.org/10.1126/sciadv.abm9424

23 Although shark teeth are abundant in the fossil record, their bodies are rarely preserved. Thus, 24 our understanding of the anatomy of the extinct Otodus megalodon remains rudimentary. We 25 used an exceptionally preserved fossil to create the fi...

The Anti-Krogh principle: all organisms are worthy of study (2022)
Journal Article
Clark, C., Hutchinson, J. R., & Garland, T. (2022). The Anti-Krogh principle: all organisms are worthy of study. Physiological and Biochemical Zoology, https://doi.org/10.1086/721620

Krogh's principle states: "for such a large number of problems there will be some animal of choice, or a few such animals, on which it can be most conveniently studied." A pitfall of this approach is it implies the question: if organisms are models f... Read More about The Anti-Krogh principle: all organisms are worthy of study.

A general locomotion control framework for multi-legged locomotors (2022)
Journal Article
Chong, B., Aydin, Y. O., Rieser, J. M., Sartoretti, G., Wang, T., Whitman, J., Kaba, A., Aydin, E., Mcfarland, C., Diaz Cruz, K., Rankin, J. W., Michel, K. B., Nicieza, A., Hutchinson, J. R., Choset, H., & Goldman, D. I. (2022). A general locomotion control framework for multi-legged locomotors. Bioinspiration and Biomimetics, https://doi.org/10.1088/1748-3190/ac6e1b

Serially connected robots are promising candidates for performing tasks in confined spaces such as search and rescue in large-scale disasters. Such robots are typically limbless, and we hypothesize that the addition of limbs could improve mobility. H... Read More about A general locomotion control framework for multi-legged locomotors.

Multi-joint analysis of pose viability supports the possibility of a salamander-like walk in the Permian tetrapod Eryops megacephalus (2022)
Journal Article
Hutchinson, J. (in press). Multi-joint analysis of pose viability supports the possibility of a salamander-like walk in the Permian tetrapod Eryops megacephalus. Integrative and Comparative Biology, https://doi.org/10.1093/icb/icac083

Salamanders are often used as analogs for early tetrapods in paleontological reconstructions of locomotion. However,
concerns have been raised about whether this comparison is justifiable, necessitating comparisons of a broader range of
early tetra... Read More about Multi-joint analysis of pose viability supports the possibility of a salamander-like walk in the Permian tetrapod Eryops megacephalus.

Walking --and running and jumping --with dinosaurs and their cousins, viewed through the lens of evolutionary biomechanics (2022)
Journal Article
Hutchinson, J. (2022). Walking --and running and jumping --with dinosaurs and their cousins, viewed through the lens of evolutionary biomechanics. Integrative and Comparative Biology, https://doi.org/10.1093/icb/icac049

Archosauria diversified throughout the Triassic period before experiencing two mass extinctions near its end ~201 Mya, leaving only the crocodile-lineage (Crocodylomorpha) and bird-lineage (Dinosauria) as survivors; along with the pterosaurian flying...

Evolution of forelimb musculoskeletal function across the fish-to-tetrapod transition (2021)
Journal Article
Molnar, J., Hutchinson, J., Diogo, R., Clack, J., & Pierce, S. (2021). Evolution of forelimb musculoskeletal function across the fish-to-tetrapod transition. Science Advances, 7(4), https://doi.org/10.1126/sciadv.abd7457

One of the most intriguing questions in vertebrate evolution is how tetrapods gained the ability to walk on land. Although many hypotheses have been proposed, few have been rigorously tested using the fossil record. Here, we build three-dimensional m...
