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.

Karla Mostert, a student at the University of the Free State (UFS), was named as the best player of the tournament at the recent South African Netball Championships that was held in Richards Bay.
At the tournament top players in each position were also identified. The best goal shooter was a Kovsie Anja Opperman. Other Kovsies included the following: Monique Lemon was named as the best centre-court player and Fikile Mkhuzangwe as the best goal keeper.
The Free State’s u.19 and u.21 netball teams that participated in the tournament entirely comprised of Kovsies. Ms Burta de Kock, Assistant Director at the UFS’s KovieSport, is very proud of the Kovsies netball players’ achievements.
Not only did they reach four of the top positions, but they also won each of the ten matches in the round robin, which took them through to the finals. Both teams brought gold home in the finals when Free State u.19 beat Gauteng East 35-25 and Free State u.21 beat North-West South 37-23.
The Kovsies students performed even better when Fikile Mkhuzangwe, Carmen Swanepoel, Ane Botha, Lauren-Lee Christians, Monique Lemon and Nieke Loubser were named amongst the top 20 players in the u.19 age group. In the U/21 age group, four of the 20 top players were Kovsies, namely Anja Opperman, Anja Zandberg, Karla Mostert and Mari-lise Linde.
“Three of our players also qualified as national umpires: Lizahn Zimmerman (Netball SA, C grading), Mari-Lise Linde (Netball SA, C-plus grading) and Johanet Coetzer (Netball SA, C+ grading),” says Ms De Kock. |
