A Dissertation submitted to the Faculty of Science, University of the Witwatersrand, Johannesburg, in fulfilment of the requirements for the degree of Master of Science, November 2012. / Hominoids practice a diverse array of locomotor behavior, from obligate terrestrial bipedalism to arboreal suspensory behavior, which is reflected in the variable morphology found in their foot bones. That hominin foot bones reflect locomotor behavior is also clear, but the forms of locomotor behaviors to be inferred are less clear. Pressure plate studies indicate that the center of pressure tends to move medially in the human foot during the last half of stance phase of bipedal gaits, while it tends to remain relatively more lateral in the bonobo and chimpanzee foot during the last half of stance phase. Here is presented a comparison of metatarsals of Homo sapiens[n=22] and two species of Pan (Pan paniscus [n=15] Pan troglodytes schweinfurthii [n=22]in order to explore the relationship between Homo and Pan metatarsal morphology and foot function. Specifically, this dissertation addresses whether cortical thickness is associated with the position of maximum change in geometry on the plantar surface in metatarsals.

The recently discovered site of Rising Star in the Craddle of Humankind, Johannesburg, South Africa, has yielded the single largest fossil hominin assemblage on the African continent to have been uncovered to date. Much of the anatomy of the new species, Homo naledi, has been described. With relatively human-like lower limb and strangely primitive-likeupper body, Homo naledi displays a mosaic of traits in its morphology. A small cranium for a member of the genus Homo adds to this unexpected mix of characters. [Abbreviated Abstract. Open document to view full version] / MT 2017
