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., …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...

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...

Femoral specializations to locomotor habits in early archosauriforms (2021)
Journal Article
Romain, P., Alexandra, H., Nesbitt, S. J., & Hutchinson, J. R. (2021). Femoral specializations to locomotor habits in early archosauriforms. Journal of Anatomy, https://doi.org/10.1111/joa.13598

The evolutionary history of archosaurs and their closest relatives is characterized by a wide diversity of locomotor modes, which has even been suggested as a pivotal aspect underlying the evolutionary success of dinosaurs vs. pseudosuchians across t...

Estimating gaits of an ancient crocodile-line archosaur through 1 trajectory optimization, with comparison to fossil trackways (2021)
Journal Article
Polet, D. T., & Hutchinson, J. R. (in press). Estimating gaits of an ancient crocodile-line archosaur through 1 trajectory optimization, with comparison to fossil trackways. Frontiers in Bioengineering and Biotechnology, https://doi.org/10.3389/fbioe.2021.800311

13 Fossil trackways provide a glimpse into the behaviour of extinct animals. However, while providing 14 information of trackmaker size, stride and even speed, the actual gait of the organism can be 15 ambiguous. This is especially true of quadrupeda...

The critical dynamic role of the tail in bipedal dinosaur locomotion (2021)
Journal Article
Bishop, P., Falisse, A., De Groote, F., & Hutchinson, J. (2021). The critical dynamic role of the tail in bipedal dinosaur locomotion. Science Advances, https://doi.org/10.1126/sciadv.abi7348

Locomotion has influenced the ecology, evolution, and extinction of species throughout history, yet studying locomotion in the fossil record is challenging. Computational biomechanics can provide novel insight by mechanistically relating observed ana... Read More about The critical dynamic role of the tail in bipedal dinosaur locomotion.

The evolutionary biomechanics of locomotor function in giant land animals (2021)
Journal Article
Hutchinson, J. (2021). The evolutionary biomechanics of locomotor function in giant land animals. Journal of Experimental Biology, https://doi.org/10.1242/jeb.217463

Giant land vertebrates have evolved more than 30 times, notably in dinosaurs and mammals. The evolutionary and biomechanical perspectives considered here unify data from extant and extinct species, assessing current theory regarding how the locomotor...

Land mammals support and move their body using their musculoskeletal system. Their musculature usually presents varying adaptations with body mass or mode of locomotion. Rhinocerotidae is an interesting clade in this regard, as they are heavy anima...

Jumping is a common, but demanding, behavior that many animals employ during everyday activity. In contrast to jump-specialists such as anurans and some primates, jumping biomechanics and the factors that influence performance remains little studied...
