This study shows pectoral and pelvic appendages evolved parallel topological changes during the fins-to-limbs transition, with digits as a key novelty reducing disparity and increasing modularity.

The paper compares bone scaling in hopping macropods and quadrupedal artiodactyls to assess how gait type influences bone adaptation to mechanical loads.

The paper measures secondary osteon dimensions in mammalian bones and finds they scale negatively with body mass, suggesting trade-offs between fracture resistance and osteocyte viability.
