    An assessment of the health status by non-specific stress indicators in early farming populations from central and southern Africa
    (2006) Dlamini, Nonhlanhla; Morris, Alan
    The adoption of an agricultural lifestyle had profound implications for nutritional ecology, health and behaviour of human populations. The goal of this project was to generate information about the health status and disease patterns of early farming populations from central and southern Africa. Skeletal material was obtained from various 'Iron Age' sites in South Africa, Ingombe Ilede from Zambia, and Sanga and Katoto from the Democratic Republic of Congo. Palaeopathological analyses was done through the examination of non-specific stress indicators that included cribra orbitalia/porotic hyperostosis, Harris lines, linear enamel hypoplasias, subperiosteal bone lesions and dental diseases. The evidence from palaeopathology indicated that the environments played a major role in causing differences observed at micro-scale level. It is suggested that the health problems of these agricultural peoples are a result of their sedentary lifestyle and aggregation, which promoted maintenance and spread of infectious diseases; as well as high carbohydrate diets and dependence on a few main foodstuffs that affected their iron levels. The individuals from the forest region were less healthy than those in the dry or wet savanna zones. Also, the impact of the stress experienced by these societies was not sufficient to cause stunted growth and thus did not affect their terminal heights. The complex relationship between the environment, socio-cultural factors and biology has shown that subsistence economy only influences a fraction of human behaviour, health and well being. The results of this study argue that generalisations about prehistoric farming peoples cannot be made, until further research work is done.

    The early inhabitants of the Upemba depression, the Democratic Republic of Congo
    (2014) Dlamini, Nonhlanhla; Morris, Alan; Sealy, Judith C
    This research set out to shed light on the contradiction between the archaeological evidence pointing towards cultural continuity and the Luba’s rejection of ancestral relationships with the human skeletal remains found in the Upemba Depression of Central Katanga, the Democratic Republic of Congo. This was done by assessing the biological variation of the human skeletal remains of the early inhabitants from the Upemba Depression in the southeast of the Katanga Province (DRC) by using metric and non-metric dental morphological traits. Dental analyses of these Iron Age people have revealed homogeneity between the sexes, time periods and sites in Central Katanga. This is in contrast with the oral history from the Luba, who believe that the Iron Age remains are of their enemies who came from the northeast. In support of the archaeology, the dental morphological results from the current research have confirmed that present-day Luba people can trace their origins in Central Katanga as far back as AD 700.The analysis of patterns of dental disease, carbon, nitrogen and oxygen stable isotopes as well as phytoliths demonstrate that the diets and behaviours varied amongst these Iron Age communities. This may have been related to differences in food preparation and hygiene.
