A Comparative Ontogenetic Study Of Biomechanical Adaptations In The Long Bones Of South African Khoisan And Sadlermiut Inuit, Kaye-Lynn Boucher

Electronic Thesis and Dissertation Repository

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 Khoisan humeri, tibiae and femora using biplanar radiographs. Biomechanical strength properties were calculated using the Eccentric Ellipse Method (EEM). EEM calculations were interpreted with consideration to the known behavioural patterns of the two groups. Humeral AP and torsional bending strength were greater in the Sadlermiut compared to the Khoisan – most likely caused by kayak paddling among the Sadlermiut. Few differences …
