Digging up truth South Africa was way different to what you thought
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 University of the Free State’s (UFS) Centre for Education Development (CED) has this week launched a project on the Main Campus in Bloemfontein.
to enable and encourage more learners to enter into science-related studies and careers.

The grant of R4,5 million over a period of three years was made by the South African National Roads Agency Ltd (SANRAL). This week’s function was attended by the representatives of the sponsors and the UFS, as well as learners, parents, principals and Physical Sciences teachers of participating schools.

The grant will be utilised to foster a positive attitude towards Mathematics and Science amongst learners in the early school years as well as raising the knowledge and skills levels of learners in the Further Education and Training (FET) Phase. “This will be done through our Family Math and Family Science Programme for younger learners and through e-Education in Science and Mathematics for learners in the FET Phase,” said Mr Cobus van Breda, Project Coordinator at the CED.

About 330 selected Grade 10, 11 and 12 learners from 16 schools in the Free State are attending Physical Sciences and Mathematics sessions during weekdays at the ICT Laboratories on the Main and Qwaqwa Campuses of the UFS. In order to make provision for the needs of generation Y-learners (techno-clever generation), the project envisages to enhance their understanding of Science and Mathematics principles by utilising the advantages of ICTs (Information and Communication Technologies) during the sessions.

On average, learners attend four sessions per term, with one of the sessions a special event like visiting Boyden Observatory, departments at the UFS, etc. Learners will be exposed to about 36 sessions over the three years. Special attention to vocational guidance, in collaboration with the Unit for Prospective Students at the UFS, forms part of the support system of the programme to participating learners.

“Learning is a life-long experience and we must encourage our learners to grab this opportunity to learn more about important fields such as Mathematics and Science. It is a privilege for SANRAL to have this partnership with the CED and the university as it is an indication of our efforts to educate our youth,” said Mr Nazir Alli, Chief Executive Officer of SANRAL.

Mr Alli encouraged learners to grab the opportunity to learn and to make the field of science their career. “Science can be the foundation on which to build your career and this programme can assist you to reach your goal,” he said.

According to Prof. Teuns Verschoor, Acting Rector of the UFS, the SANRAL grant is a wise investment because it is an educational investment. “We cannot cut back on the investments we make in education and SANRAL’s investment in this programme is of benefit to schools and learners in the central region. Through this programme, its bursaries, various career opportunities and ongoing support of schools and universities SANRAL is making a huge contribution to promoting science-related studies and careers in our country,” he said.
