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.

A degree means nothing if you are not a decent human being, Vice-Chancellor tells first-years

The 2016 Qwaqwa Campus first-year students received one of the warmest welcomes when the entire Rectorate and other senior UFS officials arrived to welcome them.

Leading the delegation was the Vice-Chancellor and Rector, Prof Jonathan Jansen, whose captivating message was well received by students and those parents who were in attendance.

“What keeps me going is your determination to come to the University of the Free State to start your life. You have done the right thing; do not forget that you are smarter than you think,” said Prof Jansen.

“Each one of you has a story to tell. You had to overcome poverty, disadvantage and abuse,” he said.

Prof Jansen encouraged first-year students to do more than just obtain a degree whilst at the university.

“This university is good not only in ensuring you get the best qualifications. Graduating and continuing to disrespect women is not good enough. Graduating and still continuing to be biased against gay people is not good enough. Getting a degree and still thinking you are better than others just because you have money is not good enough. A degree means nothing if you are not a decent human being,” he added.

In his welcoming message, the SRC President, Paseka Sikhosana, highlighted the importance of academic excellence that is backed by human embrace.

“Human embrace and academic excellence are two very important aspects that we strive for. Five of our members will be graduating this year whilst six are Golden Key members. And we have a very huge task of bringing our campus closer to the community and the community closer to our campus in an attempt to make a difference in those communities,” he said.
