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.

Qwaqwa Campus: Student off to Germany
2004-04-01

Abey Tau will be traveling to Germany in mid- August to attend an international conference under the auspices of AISEC.
Born and bred in the dusty streets of Riverside in Phuthaditjhaba, an avid reader and student activist, Abey is rapidly ascending to greater heights.

He is presently studying towards completion of his B. Admin degree at the University of the Free State Qwaqwa campus and has also been to Switzerland in the recent past.

Describing the experience, Abey said “being away from home, the influence of culture, tradition, friendship and the local environment opened my eyes to another perspective that I did not know existed before I took a step looked out of my country and at it from another angle”. He believes it will be refreshing to interact with students from across the globe and share thoughts with them.

“Ability is what you are capable of doing, motivation determines what you do and attitude determines how well you do it” Tau said, beaming confidence and enthusiasm. When the opportunity to visit Germany presented itself, he approached the office of the Coordinator of Student Affairs for assistance. Communication with the Office of the Vice Rector, Dr. Ezekiel Moraka led to the realization of Abey’s dream when funds were acquired to assist him. He will become an ambassador for his organization, the university and the country at large. We are therefore proud and wish him well.
