The evolution of human innovation in an arid biodiversity hotspot. This project will examine the archaeology and environmental history of South Africa’s Succulent Karoo, the world’s only arid biodiversity hotspot. Arid regions of Africa have historically been marginalised in accounts of human evolution yet recent evidence suggests that they were loci of innovation over the last 120 000 years. To explore the importance of such areas to the evolution of our adaptive capabilities, this project will ....The evolution of human innovation in an arid biodiversity hotspot. This project will examine the archaeology and environmental history of South Africa’s Succulent Karoo, the world’s only arid biodiversity hotspot. Arid regions of Africa have historically been marginalised in accounts of human evolution yet recent evidence suggests that they were loci of innovation over the last 120 000 years. To explore the importance of such areas to the evolution of our adaptive capabilities, this project will produce comprehensive new datasets relating to the climatic, environmental, and social contexts of innovation among early humans occupying the site of Varsche Rivier 003. The results will test prevailing models of human behavioural evolution, shedding new light on how we came to be human. Read moreRead less

DNA is the molecule of life and exists everywhere in the environment as a largely untapped source of information on evolution, biodiversity, and ecosystem health. Our overriding aim is to start mining that information to benefit threatened species. Based on optimized ancient DNA methods, powerful sequencing technology, whole genome analyses, and RNA profiling, we present a novel and holistic framework for genetic biomonitoring. In two parallel model systems we will study corals and reptiles to improve environmental detection while simultaneously obtaining information on their population health. This will foster more efficient conservation of endangered species that are of tremendous importance to our marine and terrestrial ecosystems.Read moreRead less
Determining the links between size and function in phytoplankton. Marine phytoplankton are responsible for around 50% of the carbon fixation on planet. This project will examine how phytoplankton size declines will alter marine food webs and carbon sequestration. Changes in nutrients and temperature will cause phytoplankton to be smaller but the consequences of these changes are uncertain because of a lack of knowledge regarding how changes in cell size affect function within a species. This pro ....Determining the links between size and function in phytoplankton. Marine phytoplankton are responsible for around 50% of the carbon fixation on planet. This project will examine how phytoplankton size declines will alter marine food webs and carbon sequestration. Changes in nutrients and temperature will cause phytoplankton to be smaller but the consequences of these changes are uncertain because of a lack of knowledge regarding how changes in cell size affect function within a species. This project will evolve 20 species of algae to be different sizes and estimate the consequences of these size changes for biological functions. The project will then use these data to refine global models of carbon budgets, leading to better predictions about how the global carbon pump will change. Read moreRead less
