From sagittal to sprawled: Clavicular co‐option and the evolution of forelimb mechanics in talpines

Journal of Anatomy, EarlyView.
Forelimb posture in Eulipotyphla divides into sagittal and sprawled groups with distinct scapular and clavicular orientations. First true rib strength scales with body mass, reflecting vertical ground reaction forces, whereas clavicular strength reflects differences in medially directed forces on the pectoral girdle, especially pronounced in highly ...

Human dissection and comparative anatomy: Archaeological evidence for nineteenth‐century anatomical practice at University College London

Journal of Anatomy, EarlyView.
Excavation at University College London revealed more than 8700 human skeletal fragments representing at least 38 individuals, alongside over 800 animal remains. Features consistent with dissection, specimen preparation and curation provide evidence for the use of human and animal material in nineteenth‐century anatomical education, offering rare ...
