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.
UFS Council wishes outgoing rector well
2008-09-05
Statement by Judge Faan Hancke, Chairperson of the UFS Council
The Council of the University of the Free State (UFS) hereby expresses its heartfelt thanks and appreciation to Prof. Frederick Fourie for his contribution to building and developing the UFS. His association with the UFS stretches over a period of 40 years – first as a student, later as a lecturer, dean, vice-rector and finally as rector and vice-chancellor.
When the University was operating at a loss during 2000 and it was in a financial crisis, he came up with a financial turn-around strategy which took the UFS out of this crisis to a position where it can annually spend considerable amounts on strategic projects. This led to large amounts being invested in the academia and especially research. As a result, the UFS’s research capacity and research equipment has been expanded. Since 2003 research outputs increased with about 50%, which is a great achievement for the UFS’s researchers and its faculties.
Progress was also made with diversity, the UFS’s balanced multilingualism policy in the academia as well as administration, employment equity, the transformation plan and the institutional charter. Under his leadership there was an upgrading and extension of the infrastructure, academic buildings and facilities as well as support services and student facilities.
Prof. Fourie has an excellent intellect and exceptional abilities which can still make a huge contribution to the improvement of the South African society. As a result of personal consideration and after 4 decades’ association with the UFS including 5 years in a leading position, Prof. Fourie decided to step down. The Council respects this decision and wishes him success and best wishes.
The process of appointing a new rector and vice-chancellor will follow the normal recruitment procedure of the UFS. In terms of this procedure a representative committee of Council, which includes all stakeholders of the UFS, will consider applications that are received.
Applications will be invited through an open and targeted process of recruitment advertising, locally, nationally and internationally to broaden the pool of applicants.
Within this process Council has expressed the view that applications from the designated groups in terms of Employment Equity must be encouraged.
It is also Council’s wish that this process be completed as soon as is possible, within the approved procedure.
