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.
Prof Frederick Fourie to step down: Statement by the Acting Rector, Prof Teuns Verschoor
2008-09-08
Following the announcement by Prof Frederick Fourie that he is stepping down as vice-chancellor of the University of the Free State (UFS), one cannot help but reflect on the momentous contribution he has made to the development of the UFS.
At the time of his appointment as vice-rector in 1999, the UFS was in a financial crisis. There had been three rounds of staff reductions, there were no funds for equipment or the maintenance of buildings and there was a general mood of despair amongst staff.
With his unique style and talents, and against all odds, as acting rector and as rector from 2003, Prof Fourie succeeded in bringing about a financial turnaround that once again brought hope to the staff of the UFS.
Research improved dramatically, inter alia due to the refurbishment of laboratories and the acquisition of world-class research equipment. General campus infrastructure was significantly upgraded and aesthetically improved, making the physical appearance and quality of the campus and example to other universities.
The university structure was critically analysed in all its dimensions and quality assurance projects were launched to improve the overall package of higher education offerings at the UFS.
Another initiative led to the compilation of a transformation plan that was adopted by the management and the UFS Council and that lays the basis for the years ahead.
Through these and countless other initiatives, Prof Fourie has contributed significantly to the establishment of the UFS as a nationally and internationally recognised higher education institution.
Prof Fourie has laid the foundations for the next period of academic growth and development, the value of which will only be appreciated in its full significance in historical perspective.
The UFS is saddened that the high intensity of change management processes has taken its toll on the rector, but is deeply thankful for the legacy that he leaves.
We wish Prof Fourie many productive years ahead and have faith that his remarkable intellect and capabilities will enable him to make many more contributions to the betterment of South African society.
