Disease as a Factor in the African Archaeological Record

Area of Science:

• Paleo-epidemiology and Paleo-genomics
• African Prehistory and Human Migration

Background:

• Historical African communities were susceptible to various diseases.
• Environmental and climatic factors influenced disease prevalence and spread.
• Direct evidence of disease impact on past human populations is often limited.

Purpose of the Study:

• To explore the role of diseases in shaping past African societies.
• To investigate the potential link between disease, environment, and human migration.
• To highlight the utility of paleogenomic approaches in understanding historical disease burdens.

Main Methods:

• Analysis of natural histories and paleopathological findings.
• Consideration of climatic influences on epidemic potential.
• Leveraging ancient DNA (aDNA) for paleogenomic research into disease resistance and vectors.

Main Results:

• Climate may have mitigated the impact of widespread epidemics in Africa.
• Disease presence is hypothesized as a potential driver for past population movements.
• Paleopathologists identify some endemic diseases, but African evidence is sparse.

Conclusions:

• Paleogenomic research, particularly aDNA studies, offers promising avenues for future investigations.
• Discoveries of inherited disease resistance in African populations are emerging.
• Further paleogenomic research is crucial for a comprehensive understanding of disease impacts in Africa's past.
