Digging up truth South Africa was way different to what you thought
Archaeological excavations in the Wonderwerk Cave, north of Kuruman in the Northern Cape.

Research fellow Dr Lloyd Rossouw from the Department of Plant Sciences at the University of the Free State (UFS) recently published an article in the Nature Ecology and Evolution journal with Dr Michaela Ecker from the University of Toronto as lead author, and Dr James Brink, research fellow at the UFS Centre for Environmental Management. The findings described in “The palaeoecological context of the Oldowan-Acheulean in southern Africa” provides the first extensive paleoenvironmental sequence for the interior of southern Africa by applying a combination of methods for environmental reconstruction at Wonderwerk Cave, which have yielded multiple evidence of early human occupation dating back almost two million years ago.

Where water once was
The Wonderwerk Cave is found north of the Kuruman hills (situated in Northern Cape) a 140m long tube with a low ceiling. The surroundings are harsh. Semi-arid conditions allow for the survival of only hardy bushes, trees, and grasses. But during the Early Pleistocene, stepping out of the Wonderwerk Cave you would have been greeted by a completely different site, the researchers found. Using carbon and oxygen stable isotope analysis on the teeth of herbivores (Dr Ecker), fossil faunal abundance (Dr Brink), as well as the analysis of microscopic plant silica remains (phytoliths) excavated from fossil soils inside the cave (Dr Rossouw), the results show that ancient environments in the central interior of southern Africa were significantly wetter and housed a plant community unlike any other in the modern African savanna. 

What difference does it make?
While East African research shows increasing aridity and the spread of summer-rainfall grasslands more than a million years ago, the results from this study indicate an interesting twist. During the same period, shifts in rainfall seasonality allowed for alternating summer and winter-rainfall grass occurrences coupled with prolonged wetlands, that remained major components of Early Pleistocene (more or less the period between one and two million years ago) environments in the central interior of southern Africa. That means our human ancestors were also living and evolving in environments other than the generally accepted open, arid grassland model.

Professor awarded by Cardiff University for exceptional teaching and research record
2015-10-20

Prof Pieter Duvenage
Cardiff University is one of the best research universities in the United Kingdom (UK) and the world. In 2014, Cardiff was ranked number 2 and 5 among UK universities in the Research Excellence Framework for impact and quality, respectively.

Annually, Cardiff selects and recruits the most outstanding teachers and researchers from across the globe. This year, this institution bestowed on Professor Pieter Duvenage the title of Honorary Professorship in Political Philosophy for his contribution and commitment to philosophical research in South Africa and internationally. Prof Duvenage is Head of the Department of Philosophy at the University of the Free State (UFS).

Prof Duvenage has authored and co-authored four books, publishing almost 40 accredited articles in journals and books. As a distinguished scholar, he displays immense dedication to the investigation of the political implications of intellectual traditions.

Since 1997, Prof Duvenage has been lecturing philosophy as an associate professor, full professor, or visiting professor at various South African and Australian universities. He was appointed as Head of the Department of Philosophy in 2011, where he continues to explore his interests in Phenomenology, Critical Theory, and South African Intellectual History.

His rich academic history had earned him the prestigious five-year Honorary Professorship at Cardiff’s Department of Politics.  In 2014, the same university invited Prof Duvenage to be a Professorial Fellow of the Collingwood and British Idealism Centre for an indefinite period.

Professor David Boucher, Director of the Collingwood and British Idealism Centre, has played a crucial role in initiating both processes. According to Prof Duvenage, “Professor Boucher is a respected British academic and a Distinguished Visiting Professor at the University of Johannesburg.”

When Boucher announced the good news, Prof Duvenage was very surprised. “The appointment came as a total surprise. I never studied there [at Cardiff University], therefore it was purely through academic networks.”

Considering Cardiff’s reputation and Prof Duvenage’s exceptional skill sets and values, his relationship with the world-leading university in research is bound to blossom.
