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.

Meet our Council: A teacher with a passion for changing lives
2016-12-19

William Arthur Ward once said: “The mediocre teacher tells. The good teacher explains. The superior teacher demonstrates. The great teacher inspires.”

However, a teacher can only be great and inspire when teaching is a passion and a calling.

This is exactly the case with Henry Dumisani Madlala, Councillor of the University of the Free State. Mr Madlala is the principal of New Horizon College, a private school in Harrismith.

High educational standards and quality teaching
“New Horizon College is an independent, non-racial educational institution striving to maintain high educational standards and making quality education accessible to all. We have attained a 100% matric pass rate each year in the past six years since I became headmaster."

"My recipe is simple: teachers must teach and learners must learn.”

Mr Madlala was born and bred in KwaZulu-Natal and matriculated from Amazulu High School. Afterwards, he completed a BSc degree in Mathematics and Physics at the University of the North’s Qwaqwa Campus.

Delegate, govern, and trust
He says: “There are three key management principles which I follow as principal: delegate, govern, and trust. I give responsibilities to people, I make sure that they know what is expected of them, and in the end I trust them to carry out their responsibilities.”

His career as teacher and principal has been full of highlights on which he looks back with satisfaction.

Proud to plough back into the university
Madlala has been serving on the UFS Council since 2010 and has been part of Kovsie Alumni’s executive management since 2011. He is proud to plough back into the university in this manner.

“To me, being a Kovsie alumnus means pride, respect, discipline, and loyalty. Once a Kovsie, always a Kovsie!”

For this reason, Madlala believes that the UFS will play a major role in the country and in higher education for a long time to come.

“The UFS has been in existence for more than a hundred years and will no doubt survive for another hundred years or longer. We are indeed one of the leading universities in the country when it comes to transformation and academic excellence. The survival of the UFS is not a dream, but a reality.”
