New paper out by former NSF Postdoctoral Fellow and Pierce Lab member Brandon Hedrick! By quanifying both external and internal humerus/femur shape in a large sample of rodents, we were able to show that poximal limb morphology is not correlated with rodent locomotor ecology. We propose that rodents were successful at spreading into diverse ecological niches due to high behavioral plasticity and small body sizes, allowing them to modify their locomotor mode without requiring major changes to their proximal limb morphology
