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.

Centre for Universal Access and Disability Support HOD selected as prestigious Fulbright scholar

Hetsie Veitch, who has served as the Head of the Centre for Universal Access and Disability Support at the university for the past seven years, recently won the prestigious Fulbright Scholarship for studies in the USA. Hetsie has been placed at the renowned Syracuse University in Upstate New York, where she will read for a PhD in Disability Studies in the School of Education.

By focusing on matters of social justice in the pedagogy of higher education, Hetsie will explore the creation of universally accessible learning spaces for students so that she can apply these ideas on her return to South Africa in four years.

Under her leadership, the Unit for Students with Disabilities (USD) was transformed into the Centre for Universal Access and Disability Support (CUADS) in order to reflect new approaches to universal access and universal design.“It is my ultimate goal,” says Hetsie, “to create an institutional culture that includes and welcomes all students with disabilities.”

It is difficult to fully capture the enormous contribution Hetsie has made to the UFS in disability justice, by establishing platforms for students with disabilities that enable them to be appreciated as individuals, and to excel in academic studies.

One of our star students, Gabriela Schröder, also won the prestigious Fulbright Scholarship. Gaby, as she’s called, will be taking up doctoral studies in Biochemistry at a leading university in her field, namely North Carolina State University in Raleigh, North Carolina.

Gaby earned her BSc Honours degree in Biochemistry at the University of the Free State, after also completing her undergraduate studies in Chemistry and Biochemistry at Kovsies.

She participated in the F1 Leadership for Change Programme (Class of 2011) as part of the first-year cohort that went to the University of Vermont. In 2012, she was selected to participate in the elite Stanford Sophomore College Programme with students from Oxford University (UK) and Stanford University in California.

In 2014, Gaby was awarded the Dean's Medal, a distinction which is presented to the best final-year student studying towards a Bachelor’s degree in the Faculty of Natural and Agricultural Sciences. She was also the proud recipient of the Senate Medal, awarded for academic excellence in the achievement of a Bachelor’s degree at the university.
