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.
Time is running out for applications for admission at the UFS
2009-11-25
The University of the Free State (UFS) calls on all South African prospective students wishing to study at the UFS in 2010 to submit their applications for admission by no later than 30 November 2009.
The last date for all international students’ applications for 2010 admission was 30 September 2009. All applications received from South African students after the closing date will be considered as late applications and will be handled in a separate process.
Late applications from prospective students will be accepted until 15 January 2010 to accommodate Grade 12 learners who will only receive their results on 7 January 2010.
All South African prospective students who want to apply must pay a non-refundable fee of R150. The duly completed and signed application form must be accompanied by a certified copy of the prospective student’s identity document or passport and a proof of payment of the application fee. The application form of a minor must be signed by his/her parent or guardian. The field of study should be clearly indicated.
The registration of first-time entering first-year students on the Main Campus will be from 19-23 January 2010 in the Callie Human Centre according to a programme.
The registration of senior undergraduate students (that is all students registered at the UFS up until 2009) and postgraduate students will take place from 5-16 January 2010 on a self-service system on the university’s website at www.ufs.ac.za .
Academic advice for all students during the registration period will be available in the Callie Human Centre and the Multi-Purposes Hall, as well as from the different faculties.
First-time entering first-year students on the Main Campus will be welcomed by the Rector and Vice-Chancellor of the UFS, Prof. Jonathan Jansen, on Friday, 8 January and Saturday, 9 January 2010, at 09:00 in the Callie Human Centre.
At the Qwaqwa Campus late applications will be accepted until 3 February 2010.
The registration of first-time entering first-year and senior students at this campus will be from 18-22 January 2010 in the Multi-Purpose Hall, also according to a programme. First-time entering first-year students will be welcomed on 11 January 2010.
Lectures for all students will commence on 25 January 2010 on both campuses.
