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.

First-years at South Campus step into a bright future

This is the first step to a bright future.

This was the resounding message that welcomed first-year students to the South Campus. “Remember,” Tshegofatso Setilo, Manager of the University Preparation Programme said, “a journey of a thousand miles begins with the first step.” But please do not get discouraged on your way, she urged, because “this is your first step to a bright future.

In his welcoming message, Prof Nicky Morgan, Vice-Rector: Operations at the UFS referred to the South Campus as the giant of the south. “This is one of the trailblazing campuses of the university,” he said. “No doubt what you’ll experience on this campus, you’ll never forget.”

This year, the South Campus boasts with 1 200 first-year students taking part in our University Preparation and Extended Programmes. These programmes allow students – whose matric marks did not reach the required total – the opportunity to study at the University of the Free State (UFS). The result? An astounding rise in pass rates. Some of the students on the South Campus outperform their peers studying at the Bloemfontein Campus, Prof Morgan remarked.

“You’ve got it in yourself. You’ve got the potential to unleash yourself on the world,” Prof Morgan said. You do not always realise the value of something that has come your way, he said. So, every moment you get an opportunity, he advised, use it to shape your future.

Addressing the newcomers’ fears, Prof Morgan urged each student to open themselves to the good and new experiences waiting for them. “When you find yourself in a new space, it always begins with you,” he said. Learn to understand how to live in harmony in different spaces.

Prof Morgan placed great emphasis on his closing remark: “At university, the more questions you seek to have answered – they’re worth more than the answers you have.”
