A Comparative Ontogenetic Study of Biomechanical Adaptations in the Long Bones of South African Khoisan and Sadlermiut Inuit
This research examines and compares the biomechanical adaptations of juveniles from two different climate-adapted populations: Khoisan foragers from South Africa and Sadlermiut Inuit from Nunavut, Canada. Cortical bone measurements were recorded at three diaphyseal locations on the Sadlermiut and Kh...
