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.

The Kovsie Open Day 2010 that took place on the Main Campus of the University of the Free State (UFS) in Bloemfontein last week, was attended by more than 6 000 prospective students and their parents. This event was a resounding success. Thus report our prospective students, their parents, campus personnel, as well Prof. Jonathan Jansen, Rector and Vice-Chancellor at the UFS.
Parents and learners from across South Africa were firstly welcomed by Prof. Jansen, the Deans and Moses Masitha, the President of the Student Representative Council (SRC) in the Callie Human Centre. Thereafter they were afforded the opportunity to visit the various exhibitions in the faculties and residences. Parents and learners could also complete application forms for entrance to the UFS in the tent of the Division Corporate Relations on the Red Square. Liesl Cronje from Magaliesburg, who wants to come and study B.Sc.Agric. at Kovsies, was named as the winner of R3 000 by Corporate Relations after her application form had been selected in a lucky draw.
Residences and student organisations also had information points on the grass in front of the Main Building, where more information was given out to prospective students. Armentum, Vishuis and Karee won the first, second and third place respectively with their information points. The ladies’ residences Vergeet-my-nie, Emily Hobhouse and Soetdoring respectively boasted with the best information points.
The first official Kovsie slogan competition was also held and Madelief was appointed as the winner.
This day was held to provide prospective students and their parents with the opportunity to become better acquainted with the distinctive quality that the UFS offers its students. Staff and students also provided learners with the necessary information to enable them to make the right decisions regarding their career and studies next year.
