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.

Applications for admission to the University of the Free State (UFS) are showing an upward trend. In comparison with the same time last year, the total application figure has increased from 6 273 to 7 507 – a growth of 19,7%.
So far, applications for postgraduate studies are showing the biggest growth with 1 342 applications received. During the same time last year, 594 applications for postgraduate studies were received – an increase of 126%.
Prospective students have until 30 November 2008 to apply for admission. “This applies to first-time entering first-year students and senior students who have interrupted their studies for at least one year,” said Mr Vernon Collett, Registrar: Student Academic Services, at the UFS.
According to Mr Collett students whose applications for admission are received after 30 November 2008 and until 13 January 2009 will be accepted subject to the availability of place on the programme they applied for.
Applications from prospective students who wrote the Senior Certificate (prior to 2008) and who are in the possession of a conditional exemption will only be accepted until 5 January 2009.
Prospective students who want to apply must pay a non-refundable fee of R140.
The signed application form must be accompanied by a certified copy of the prospective student’s identity document or passport, a proof of payment of the application fee as well as a certified copy of their Statement of Results of their Senior Certificate.
Prospective students who are in Grade 12 this year will receive a National Senior Certificate. A certified copy of their Statement of Results must be faxed to the UFS not later than 7 January 2009.
The application form of a minor must be signed by his/her parent or guardian and the field of study should be clearly indicated.
First-time entering first-year students from the Faculties of Economic and Management Sciences and the Humanities (including Education) will be welcomed by the Acting Rector, Prof. Teuns Verschoor, on Friday, 9 January 2009 at 09:00 in the Callie Human Centre on the Main Campus.
The welcoming of students from the Faculties of Health Sciences, Natural and Agricultural Sciences, Law and Theology will take place on Saturday, 10 January 2009 at 09:00 in the Callie Human Centre.
The registration of first-time entering first-year students will commence on 13 January 2009 and that of senior students on 19 January 2009 at the Callie Human Centre according to a programme.
Students who applied for admission after 30 November 2008 and are accepted can register from 4 February 2009.
Lectures will commence on 2 February 2009 and the registration process will end on 10 February 2009. This is applicable to all students – undergraduate as well as postgraduates
