This project is documenting the knowledge, skills, and practices of traditional dry-stone masonry at Great Zimbabwe, southern Zimbabwe. Once the capital of an Iron Age empire, Great Zimbabwe is an ancient settlement complex with dry-stone structures covering over 720 hectares. Around it, local communities live and maintain ancestral connections to the site. The most outstanding material remains are stone structures, built without use of mortar or any binding material.

Tracking the early emergence of derived Homo-like cerebral features in the hominin fossil record can be expected to contribute to an understanding of the timing (i.e., chronology) and mode (i.e., process) of critical brain changes. Because brain tissue is not preserved in the fossil record, studies of hominin brain evolution focus on brain endocasts (i.e., replicas of the inner table of the bony braincase).

How did our ancestors walk? Perhaps the greatest challenge that this question has posed in the past, is the lack of methodological applications in which no study has previously reconstructed how our ancestors moved using biomechanical modelling techniques. We need to consider not just individual bones when reconstructing movement, but to look at the full body to begin to tell the story of our ancestors’ movement. Muscles animate our body, permitting us to walk, run and even dance. We must reconstruct the muscles of the body to understand ancestral locomotion.

Despite recent progress in molecular analyses and the constant increase of the hominin remains in the fossil record, the chronological, geographical and evolutionary context of the emergence of the genus Homo remains largely debated. More importantly, the identity of our direct ancestors and assessment of the adaptations characterizing our genus remain unclear.

Igbo-Ukwu is a famous archaeological site in southeastern Nigeria. Excavated by Professor Thurstan Shaw in the 1960s, the site was settled over a thousand years ago. The materials from the site were unlike anything yet found in West Africa at the time. This discovery brought to our consciousness that Igbo-Ukwu represented a prosperous society that had established a complex social structure by the 9th century CE and had significantly interacted with the wider world through interregional and intercontinental exchange and trade.

This project is examining resource landscapes and urban transition on Zanzibar during two major periods of urban growth. Fieldwork at Unguja Ukuu (7th–15th centuries) and Tumbatu (11th–15th centuries) on Zanzibar is exploring domestic contexts and investigating resource uses supporting the development of towns.

Geoarchaeological surveys and analyses are developing new multi-scalar sampling strategies for mapping and tracing land, water and building material resources for settlement, and their uses within houses.

This project brings together several research streams to examine the nexus relations between land and water resources, societal development, and landscape stability in sub-Saharan Africa. What processes and practices support long-term settlement and resource use? How did past societies secure water for settlement and urban growth? To address these questions, new landscape historical ecology research is exploring resource nexus at Aksum and Great Zimbabwe.

This is a collaborative research project between archaeologists and pastoralist community organisations on the long-term history of indigenous water management and well digging in northern Kenya and southern Ethiopia. In these arid and semi-arid parts of eastern Africa, wells form a key component of pastoralist biocultural heritage. Community identities and understandings of the landscape are entwined with knowledge – sometimes contested – about water sources, and particularly about the wells dug across the region by earlier generations.

As the complex mosaic of Quaternary human lineages across and beyond Africa becomes increasingly apparent, an accurate chronology is critical to disentangle the patterns and process, particularly those that link human evolution to palaeoenvironmental and climatic change.
