A Study through Skull Morphology on the Diversity of Holocene African Populations in a Historical Perspective - Isabelle Ribot

The main objective of the present research is to explore through skull morphology some potential sources of biological diversity within sub-Saharan Africa, such as: geography and especially history, in relation to large-scale population movements (expansion of Bantu-speakers). Therefore, through various statistical analyses, morphological variation was re-evaluated within modern sub-Saharan African populations, using a very large modern human sample and a set of metric variables related to the cranium and mandible. In the same way, morphological patterns through time were also traced, focusing on various Later Stone Age and Iron Age populations, originating in particular from strategic areas of various influences. In Chapter 2 after having briefly introduced both geographical and historical backgrounds of sub-Saharan Africa, the dispersal of Bantu-speakers, a very long-term and large-scale phenomenon, which initiated since the Early Iron Age (c. 1,000 BC) is presented in more depth. In Chapter 3, after a detailed presentation of the populations and variables under study, a preliminary analysis of inter- and intra-observer errors is presented. In chapter 4, various factors (geography, sex and ecology) are tested as a source of modern diversity. Chapter 5 looks a the effects of historical factors on skull morphology through both modern and past African diversity. Following the conclusion the author presents an extensive assemblage of Appendices (sites and datasets).
