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.

Prof. Dennis Francis from the University of KwaZulu-Natal has been appointed as Dean of the Faculty of Education at the University of the Free State (UFS) as from 4 January 2010. He is the first dean of this faculty since it was established at the UFS earlier this year.
Prof. Francis has worked at the University of KwaZulu-Natal since 2002. Prior to his appointment at the UFS he was a Professor in the Faculty of Education and Head of the School of Social Science Education at that institution.
“I am overwhelmed and excited at the same time. Mostly, I feel privileged and honoured to be joining the Faculty of Education,” he said of his appointment.
“The Faculty of Education is newly constituted and there are endless possibilities and potential. So I am really excited to be here.”
“What attracted me to the UFS is the leadership and vision of Prof. Jonathan Jansen, the emergent energy that is here, and the possibilities for transformation and change that exist. But also the warmth and graciousness of the people that I have interacted with,” he said.
Prof. Francis has taught and supervised Master’s and Doctoral students in the area of social justice education, identity studies and sexuality education. He has published numerous articles in refereed national and international journals, chapters in edited collections, and four edited journal special issues. He is also the author of Between Race; Beyond Race. Prof. Francis is the current guest editor of the South African Journal of Higher Education Special Issue on Transformation and Social Cohesion in Higher Education.
He has delivered conference presentations in his fields of research at international conferences in India, USA, Brazil, Thailand, Greece, Malaysia, Mauritius, UK and South Africa, as well as a further fifteen papers at national conferences. At three of these conferences he was an invited speaker. In 2008 he was granted researcher status by the National Research Fund.
Prof. Francis is currently on the editorial boards of two journals and an advisor on two international education conference committees. He also serves as the Chairperson of the Kenton Education Association.
