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.
Students get a place to rag

A jol place where students from the University of the Free State (UFS) can socialise during events such as rag and intervarsity was officially handed over to the UFS by the builders this week.
The Jol place, which is situated on the Western Campus, has ten float building areas, each with its own power points (currently temporarily) and container (also temporarily). There are also outside taps and high-mast lights on the premises and a large area has been paved. The covered area includes an open stoep, kitchens, a bar, and a stage with artists’ dressing rooms as well as bathrooms for men and ladies and for persons with disabilities. The premises, that includes wooden and concrete benches, can accommodate 1 200 people.
The total project cost for this facility was R6,3 million, of which just over 50% was contributed by Absa.
Attending the hand over ceremony were, from the left: Prof. Frederick Fourie (Rector and Vice-Chancellor of the UFS), Mr Natie Botes (from the building company Ströhfeldt Sikeye Joint Ventures), Ms Edma Pelzer
(Director: Physical Resources and Special Projects and the UFS), Dr Natie Luyt (Dean of Student Services), and Jolice Neniëls (forth-year LL.B. student).
