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.

On Thursday 5 December 2013, the University of the Free State (UFS) will award more than 300 degrees and qualifications during the Summer graduation at the Bloemfontein Campus.
The graduation will take place during two ceremonies in the Callie Human Centre, where master’s and PhD degrees will be awarded during the first ceremony at 10:15 and diplomas, certificates and undergraduate qualifications awarded to students from the School of Open Learning and the Faculty of Health Sciences at 14:30.
An honorary doctorate from the UFS will also be bestowed on the author, Dr Zakes Mda, during the morning ceremony.
Dr Mda is a South African literary icon and public intellectual with extraordinary local and international influence. Mda’s contribution to world literature and contemporary South African public life resonates powerfully with some of the fundamental principles of the Academic and Human Projects articulated in the strategic thrust of the University of the Free State, which makes him an ideal candidate for an honorary doctorate from our university.
Some of his most famous works include Ways of Dying, Heart of Redness, The Madonna of Excelsior, The Whale Caller, Cion, Black Diamond and his recent memoir: Sometimes There is a Void: Memoirs of an Outsider.
The Springbok rugby player, Jannie du Plessis, will address graduandi during both ceremonies.
