International scientists bring understanding of human evolution

Plant Sciences Congress — At a public seminar, Understanding human evolution through the study of past environments in the Free State, presented by the UFS Department of Plant Sciences, were, from the left, front: Kristen Wroth, Britt Bousman; back: Prof Louis Scott, mentor in the UFS Department of Plant Sciences, and Michael Toffolo.

Florisbad, a thermal spring situated 45 km northwest of Bloemfontein on the edge of a large dry saltpan, is a well-known fossil site that used to be a large lake where giant buffalo, blue wildebeest, and hippos roamed thousands of years ago. Today, this fossil-bearing spring is not only a tourist attraction and a venue for weddings, but also an established quaternary research station that has attracted several palaeo-scientists since the 1930s, following the discovery of a remarkable human cranium and other fauna.

Studies of past environments

Three international researchers studying different aspects of archaeology at this and other sites in the Free State, recently presented lectures at the UFS to a multidisciplinary group of academics in plant sciences, geology, geography, and environmental management.

These lectures are part of the ongoing collaboration regarding fossil plant (pollen), fauna, and archaeological studies between the University of the Free State (UFS), the National Museum, and universities abroad.

Florisbad, a key site for understanding the appearance of modern environments as well as modern humans in Southern Africa, is the focus of the investigations of all three visiting scientists, aiming to provide a better understanding of past Free State environments where human evolution has taken place.

Michael Toffolo, a junior research chair from the University of Bordeaux Montaigne in France, focuses on the reconstruction of site-formation processes, palaeo-environments, and ancient human activities based on the study of the micro-morphology of archaeological deposits. He has been working in Southern Africa since 2013. The title of his lecture was: Reconstructing Pleistocene environments in the Free State by looking at the microscopic sedimentary record.

Fluoride-preserved bones

Florisbad is widely known for the discovery of an archaic modern human skull of c. 260 000 years old. According to Toffolo, the human probably died, and the remains was left at the spring by the hyenas. The bones consequently absorbed fluoride from the spring water, which counteracted decomposition and helped to preserve it.

Britt Bousman talked about middle and late Pleistocene terraces and archaeology in the Modder River Valley. He has worked in Southern Africa for the past 43 years and started his collaboration with researchers from the UFS and the National Museum in 1985. They have worked together at several sites, investigating palaeo-environments. Bousman teaches Archaeology in the Department of Anthropology at the Texas State University.

While most scientists study early human records in rock shelters, especially those near the coast where seafood was harvested by prehistoric people, he is one of only a few researchers who studies the evolution of early human behaviour in central South Africa in the context of their activities in the open environment.

“Rock shelters are good spaces for human behaviour,” says Bousman. He believes, however, that the Modder River area is a better space to study how humans have survived on the land under changing climatic conditions in the long term; for example, how they hunted and slaughtered animals. This can be seen from the many artefacts they left, such as spearheads, scrapers, etc. Interesting animal remains were also found, such as the bones of an extinct giant zebra at the Erfkroon site along the Modder River, with a head measuring 63 cm compared to that of a current zebra, which measures 54 cm. The only complete horn core of an extinct giant wildebeest was also found at the site.

The first chemists

According to Bousman, technology changed in the Stone Age and included the production of more grinding stones, indicating that humans collected plants and grinded them. Observations of modern plant-collecting activities suggested that not many plant foods needed grinding. Bousman proposes that different plant components may have been grinded for medicinal mixtures, therefore these ancestors may have assumed the role of chemists.

Kristen Wroth, a postdoctoral researcher in the Geoarchaeology Working Group at the University of Tübingen, Germany, presented a lecture on early human-environment interactions and ancient pyro technology. She uses a suite of micro-archaeological techniques such as phytolith (microscopic plant silica) analysis, micromorphology, and FTIR to understand both human and Neanderthal behaviour and to reconstruct how local environments have changed in space and through time.

SRC Inauguration speech: 22 January 2005

2005-01-22

Campus Head (Prof Peter Mbati). Dean of Students (Dr Natie Luyt). Deputy Director: Student Affairs and my boss (Mr. Teboho Manchu), Members of the University executive and Academic staff members, SRC members, Leaders of trade Unions and Student organizations, Distinguished guests, Ladies and gentlemen, most importantly first entering students and Parents receive my heartfelt revolutionary greetings.

Let me extend my word of appreciation to our distinguished guests for adding value and dignity to this event. Your presence here means a lot to us. Program Director what I bring here with me, assisted by facts, and is therefore just the work of my imagination. Like a love letter addressed to a sweetheart miles away, even though you do not know how she feels, what she wants to hear, and do not even know how her face looks like.

To me a speech is just an honest and intimate conversation. That is why I got into the habit of establishing a dialogue, or a debate, with my acquaintances looking at their faces and trying to persuade them of what I am telling them.

Mr. Speaker and Madam Deputy Speaker of the Student Parliament we are gathering at this ceremony, significantly few weeks after the release of grade 12 results, with the exception of those from Mpumalanga because of fraud. The Grade 12 results also show that only 18% of Black learners matriculated with exemptions, as compared to 53, 6% of white learners. This is an indication that our education system needs an overhaul.

We are also gathered here significantly a day after the management retreat held in Bloemfontein, Masselspoort. The retreat discussed, among other things, the transformation agenda, and some possible solutions to challenges we are facing now.

Most regrettably, we are gathered here when the whole world morns the victims of Tsunami tragedy. Let me therefore tore the line and convey our deepest condolences, from the last robot of my heart, to the affected families. Our hearts and thoughts will always be occupied by this horrified tragedy.

Creating a new Institution

I would submit, for purposes of debate and discussions that this Institution should strive to specialize and excel in regional rural development studies. Since our higher education, institutions in South Africa are generally weak in rural development studies. Instead, most of them tend to have an urban orientation to their programmes. Training everybody for the cities, big business and the private sector. This is a big weakness in a country with such large rural areas and population trapped in poverty, disease and ignorance.

Women’s studies

Program Director, it is only a moron who can argue against the fact that for us to reposition the institution around the regional development challenge, we need to start first with women empowerment. It is a fact that in most of our poor communities and families, it is women who withstand the worst of poverty. They are the ones who daily have to wipe tears from children who are hungry. It is women who look after the sick, the elderly, those dying from AIDS and the jobless. They are the one who have to fetch water, make fire and cook. There can therefore be no rural development studies without women studies, in particular on how to empower them and assist in the provision of basic services, so that they are relieved from some of the burdensome task of the society.

Registration Process

Mr. Speaker and Madam Deputy Speaker of the Student Parliament let me indicate that the registration is a process and not an event, so it cannot be concluded overnight. This huge process demands for people to stay calm, as there is no crisis. People should stop being excited. At the same time, no organization should use its cheap popularity and unilaterally disrupt the continuous and smooth running of the registration process at hand.

Let me strongly indicate, madam deputy speaker, that I am on record for stating that I have forgiven all those who have wronged us. I harbour no bitterness towards the protagonists of our painful and unfortunate events of the past week. And we will overcome this process not by our own devices but by the help of Almighty God and the grace of our Lord Jesus Christ.

Concerning registration of first years, we have programs, concerning that of senior students, we have programs, regarding graduations we have programs, and concerning HIV\AIDS we have programs. So, there is no need for people to press panicking buttons.

Mr. Speaker and Madam Deputy Speaker of the Student Parliament let me be opportunistic and welcome the entire student body on Campus for the academic year 2005. May our lovely first entering students have a happy and momentous year as part of Qwaqwa Campus of University of the Free State. May your studies be fruitful and enjoyable.

Student years are generally the happiest years of your life, so please make the most of them. While you are doing, all your preparations bear in mind that University is not an opportunity, it is just creating opportunities for a person.

On behalf of SRC members, our people, our students and management members I would like to welcome you all. Even though your parents are far away, here at Uniqwa you have more brothers, more sisters and more parents. Since we will love you with the same love as if we are from one family, and I have no doubts that management members will love and care for you as if you are their own children. Should you encounter any problem while studying at the Qwaqwa Campus of University of the Free State do not hesitate to contact us at the SRC offices because we need to ameliorate any factor influencing you negatively while on campus. I wish you well in the attainment of your academic pursuit.

Senior Students: We are not faced with just a new year but another academic year where we all have to work together to achieve our common goal of building our Institution through the development of human power. I urge you to invest your whole selves in this SRC.

For quite some time now, a debate has been ranging as to, whether has there been any progress in this incorporation process, or we are just moving with no direction. This debate is important, but I hasten to add not essential. The SRC is also involved in this debate, but with definite shift in emphasis. For us it is not important to participate in the debate than it is in finding solutions for the challenges of this new chapter in the history of humankind.

To my colleagues: Comrades, we are leading this Institution with a sense of pride and duty, and I know very well that we lead men and women, students who are determined to ensure that we all reach our destination safely and on time.

I said in one of our meetings that there are more enemies on our way, more than we can imagine. I think you witnessed that during the course of this week. The excitement and unnecessary confusions caused by some confused and loosed charlatans bear testimony to my statements. We should not reveal our game plans unless we are ready to slam.

Let me also borrow from the words of the late Albert Lethuli when he said and I quote: “There remains before us the building of the new land, from the ruins of the old narrow groups, a synthesis of the rich cultural strains which we have inherited. The task is immense”. Lastly, a navy divided within its ranks will be vanquished and destroyed by the enemy, but a navy united in purpose and action, loyalty and commitment will not drawn but sail on to victory.

In conclusion, let me call upon all political structures, church denominations, developmental structures, clubs, societies and forums to put aside all their differences, ideological insinuations and forge unity towards transforming Qwaqwa Campus of University of the Free State into an institution that is seen playing vigilant role in developing students academically, politically, socially, spiritually, religiously, culturally and otherwise.

Program Director, let me end my speech by indicating that every drop of my blood is telling me that Uniqwa is my home. I firstly became a student here, I became an activist here, I became a leader here, I became a president here, I will become a graduant here and hopefully I will become an employee here. So never, doubt my commitment towards the community of this campus.

Please be informed, in a central University of Technology’s way, that if there is no UNIQWA in HEAVEN, then I am not GOING.

Let us broaden the social base.
