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.

Standing in solidarity against suicide
2015-09-28


Students take collective action against the plight of suicide

Many students are battling depression, and have contemplated suicide. Some have lost the battle and, in turn, their lives. Suicide is a difficult topic to discuss and, even more challenging, to face its repercussions. The Leadership for Change (F1) 2014/2015 cohort took the initiative to change this through the TooSoon campaign.

A day after International Suicide Awareness Day, on Friday 11 September 2015, students marched in solidarity from Thakaneng Bridge to the Red Square on the University of the Free State’s Bloemfontein Campus.

The TooSoon team has forged links with the student community, Student Affairs, Student Counselling and Development, as well as the Health and Wellness offices to break the silence about the topic of suicide.

Every student has the potential to live a long and purposeful life. So, when someone ends his or her life, it is always too soon: this is the message the team is communicating. Awareness-raising was kick-started in August, with information sessions held at residences across the campus and the Bridge. The campus was plastered with posters offering emergency contact details for those in need of counselling, and culminated in the silent march.

At the end of the march, those who had already lost the battle were remembered through song and poetry. Students then pledged their support by painting their fingers with yellow paint and printing them on a canvas,,symbolising their solidarity in the fight against suicide.
