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.
New residences for Qwaqwa Campus

The Qwaqwa Campus of the University of the Free State will have new residences before the end of this year to ease the growing demand for student accommodation.
According to the Deputy Director of Housing and Residence Affairs at the Qwaqwa campus, Rev Hosiah Nkoana (pictured), the university is spending a lot of money on the rent and maintenance of the residences of the former colleges of education, Tshiya and Bonamelo, that the university has been using since 2004 to accommodate students.
The construction of these new residences will be carried out in two phases.
“The first phase will be university-funded and the residences will accommodate 200 students, male and female. The second phase will be a private development by a private developer. The residences in this phase of construction will accommodate 500 students – and this will be its first phase. It will then be followed by a second phase, depending on the demand for accommodation,” said Rev Nkoana.
“These residences will not necessarily be state-of-the-art residences but they will have good facilities that will underwrite our approach that residences are not just sleeping places.”
“We are developing a philosophy of turning our residences into learning and living areas. So, to get there we are going to put up a computer lab with 100-150 computers between the residences so that all resident students can access them to enhance the learning side of residence life. I hope this will change the way our students see residences,” he said.
Currently the residences at the Qwaqwa Campus can accommodate 770 students. The new residences are expected to be ready for occupation in the 2011 academic year.
