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 gets more than R3 Million for HIV/Aids activities
The Chief Directorate: Community Service at the University of the Free State (UFS) has received more than R3 million to intensify activities regarding HIV/AIDS at all UFS campuses for the next seventeen months.
Higher Education HIV/AIDS Programme (HEAIDS) contributed R3 127 207 and the UFS R615 116 towards this initiative. The money will be used to implement intervention strategies from 1 January 2008 to 31 May 2009.
“The mandate poses an extensive challenge and puts pressure on the institution, but at the same time creates some incredible opportunities for intervention,” said the Chief Director of Community Service and Project Co-ordinator, Rev. Kiepie Jaftha.
HEAIDS is a nationally co-ordinated initiative to develop and strengthen the capacity of South African higher education institutions to respond to the causes, challenges and consequences of the HIV/AIDS pandemic in the sector. It is an initiative of the Department of Education and the implementing agency is Higher Education South Africa (HESA), an organisation representing vice-chancellors of tertiary institutions in South Africa.
The proposed areas and actions of intervention are categorised into three main components, namely:
- Prevention, treatment, care and support aimed at both students and staff on all UFS campuses.
Incorporation of HIV/AIDS issues into the teaching offerings of the UFS and the development of a formal policy in this regard.
- Implementation of an integrated management information system to empower stakeholders to make decisions and adapt actions by visualising facts, actions and progress on the overall HIV/AIDS programme.
The UFS met all the requirements of HEAIDS to qualify for this funding. A five-member team was formed to come up with a document entitled The Quest for an AIDS Competent Society that met the required standards.
“Each institution of higher learning had to identify and establish a project team, appoint a project leader, assign responsibilities to members of the team with different expertise, analyse the needs of the institution, and define and agree on projects in order to access the grant,” said Rev. Jaftha.
