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.

Master’s student awarded Mandela Rhodes scholarship

Candice Thikeson was recently selected as the only 2016 Mandela Rhodes Scholar from the University of the Free State. She is one of 50 young African postgraduate students, eager to contribute positively to the educational development of the continent.

The Mandela Rhodes scholarship is a fully-funded postgraduate scholarship awarded to promising future leaders by the Mandela Rhodes Foundation. It is named after the former president of our country, Nelson Mandela, and Cecil Rhodes, who was known for his business skills and political influence in South Africa. Instituted in 1999, the scholarship aims to advance scholars who demonstrate the principles of Leadership and Reconciliation embodied by Mandela and Rhodes’s legacy, as they relate specifically to Education and Entrepreneurship.

Thikeson expects the programme will educate her on how to integrate the four pillars in relation to her field of study.

For Thikeson, earning the scholarship served as an endorsement of her dream of becoming an academic. “I want to obtain a PhD, lecture at a university, publish papers, and speak at conferences,” she related. “I also want to produce academics, I want to mentor young people,” she added.

Her academic journey began in 2011 when she pursued a BA Fine Arts degree for a year. Thikeson then transferred to a BA General degree which she completed over two instead of the standard three years. She went on to study an Honours degree in Art History and Visual Culture Studies. In the same year, she travelled to Rijksuniversiteit Groningen (University of Groningen) in the Netherlands as part of an exchange agreement between the university and the UFS, where she completed her mini-dissertation in four months. Both her BA and Honours were passed with distinction. Currently, Thikeson is pursuing a Masters degree at the Department of Art History and Image Studies under the supervision of Prof Suzanne Human.

Some accolades to her name include the Jan Teurlinckx Prize for the best student in Art History (2011), the David Jacobs Prize, awarded to the best student in Philosophy (2013), and the Richard Miles Prize, presented by the Dean of the Faculty of the Humanities (2013). Thikeson was also selected as a member of the Golden Key Honour society in 2012, for her consistent academic excellence.

Last year, Lehlohonolo Mofokeng, Zola Valashiya, and Tumelo Morobane made the UFS proud by graduating as the class of 2015 Mandela Rhodes Scholars.
