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.

Kovsie student aims for the record books

The Guinness World Record for the longest continuous wheelie in a wheelchair was achieved by Michael Miller of the United States, who covered a distance of 16,12 km on the rear wheels of his wheelchair on 8 August 2009.

On 11 October 2011, Hermann van Heerden, a second-year Kovsie student, will attempt to set a Guinness World Record for the longest wheelie in a wheelchair in a stationary position. The 22-year-old disabled student from the University of the Free State (UFS) will manoeuvre his wheelchair so that the front wheels lift off the ground.

Hermann, who is studying for a BEd degree, was born with spina bifida, a developmental congenital disorder caused by the incomplete closing of the embryonic neural tube. He has been in a wheelchair since he was a toddler.

Hermann’s Guinness World Record attempt forms part of the ten-year celebrations of the Unit for Students with Disabilities (USD) at the UFS. The unit was established in February 2001, with fifteen registered students, but currently supports 143 registered students. The USD focuses on promoting equity for students with disabilities, including access to courses, buildings, learning materials, residences, leisure and sports activities and the opportunity to succeed in such activities.

The unit supports students with specific learning difficulties (dyslexia, attention deficit hyperactivity disorder); mobility–impaired students (wheelchair users and amputees, as well as those suffering from cerebral palsy, muscle dystrophy, spina bifida and multiple sclerosis); visually-impaired students; hearing-impaired students, students suffering from “other” conditions (mental impairment ((schizophrenia)), epilepsy, panic disorder) and those with temporary impairments (broken hand).

Hermann said that he would like to use his record attempt as a means of raising money for the USD and welcomes sponsorships. “The USD has only been good to me ever since I registered at the UFS. Every time I had a question, they answered it. Every time I had a problem with a class, they resolved it. This year, the unit has its ten-year anniversary and I thought it was time for me to give back.”
