The acclaimed scientific journal, Nature, recently published an article about a trace fossil in approximately 543-million-year-old rocks, which elucidates the evolution of the first animals that appeared on Earth and lived in the sea.  

Affiliated Professor in the Department of Geology at the University of the Free State (UFS) Prof Gerard Germs formed part of a team that conducted research with the aim of understanding how the evolution of the first multicellular animals came about and how the Cambrian explosion took place. Prof Germs is of great value to the team for his extended field geological knowledge.

An article which he co-authored was published in the Nature Scientific Reports. The title of the article is: “Sediment disturbance by Ediacaran bulldozers and the roots of the Cambrian explosion”. The international group of writers included authors from Canada, Spain and South Africa. 

Occurrence of the Cambrian explosion
Prof Germs explains the Cambrian explosion: “During the long (4.5-billion-year) history of the Earth, the first life originated and subsequently evolution of plants and animals took place from one-cellular organisms to multicellular vertebrate animals and seed plants. Approximately 573 million years ago the first multicellular animals appeared on the scene. Sometime afterwards, approximately 540 million years ago, a kind of explosion in the origin of many new animal species occurred. This explosion is known as the Cambrian explosion.”

The team studied Earth sediments which are somewhat older than the Cambrian explosion. Such sediments are approximately 573 to 541 million years old and form part of the Ediacaran (late Neoproterozoic) period.

“My discoveries of the past, of among others, the oldest animal with a carbonate skeleton (Cloudina) and of complex horizontal Cambrian-type “worm” tracks (treptichnids) in Ediacaran sediments of Namibia have demonstrated that the Cambrian explosion occurred more gradually than previously thought. This has recently been confirmed in the article that was published in the Nature Scientific Reports.”

Pretzeliformis bulldoze to search for food
According to the article there is evidence that   during the Ediacaran period   worm-like animals such as the Parasammichnites pretzeliformis were already so far developed that they, due to coelom development and size increase, for the first time in the history of the Earth, were able to disturb and bulldoze sediments.  In this way they were able to find a new food source in sea sediments. Bulldozing animals were previously thought to have originated only during and after the Cambrian explosion and not during the older Ediacaran.

“Another major aim of my cooperative research is to improve our knowledge of the geology of the Ediacaran to early Cambrian of South Africa and Namibia. We also intend to establish how the assembly of the supercontinent Gondwana took place. This improved knowledge can be of great future economic interest since large oil, gas and limestone sources occur in Ediacaran-age sediments outside South Africa”.

Dean of the Faculty of Law delivers farewell lecture
2013-12-04

Prof Johan Henning, Dean of the Faculty of Law at the University of the Free State (UFS), delivered his farewell lecture during an event attended by distinguished guests from law circles in Bloemfontein, staff from the faculty, as well as family and friends.

The topic of his farewell lecture was: From leonine to universal partnerships. This theme was also the focus of his inaugural lecture and his later research. “It was a privilege to have been part of the development of universal partnership law,” Prof Henning said.

During the event, Prof Henning was honoured by colleagues, as well as members of the law profession, for his contribution to the academy. Prof Jonathan Jansen, Vice-Chancellor and Rector of the UFS, thanked Prof Henning for his part in preparing a new generation of academics for the future.

Prof Elizabeth Snyman-Van Deventer from the Department of Mercantile Law, described Prof Henning as someone with an excellent knowledge of history, especially with regard to the Anglo-Boer War and the World Wars. “He is also one of only a few academics of which four postgraduate students became professors. He has lots of empathy with other people and, despite his long list of academic achievements, he is a very humble man. Two of his outstanding characteristics are his humanity and his modesty,” said Prof Snyman-Van Deventer.

Judge Faan Hancke, former chairperson of the UFS Council and Judge of the Supreme Court, said Prof Henning is a multi-faceted person. “He is an incredible academic who has published widely and is the author of several textbooks. He is also editor of a number of journals and serves on the editorial board of several publications. I have great admiration for his academic excellence and his absolute knowledge of partnership law. He is the best in South Africa and is also highly regarded internationally in this aspect of the law (he was, among others, director of the Centre for Comparative Partnership and Company Law at the Institute of Advanced Legal Studies of the University of London). He is the ideal academic, who has achieved the highest rating in his specialist field of Mercantile Law in South Africa, namely a B1 received in 2012, and he is an excellent dean,” Judge Hancke said.

Prof Henning has a long association with the UFS. In 1968 he reported as a first-year student. Later, in 1974, he was appointed in the Department of Mercantile Law on a temporary basis. In 1998 he was appointed as Dean of the Faculty of Law. Some of the highlights in his career include his appointment as African representative of CIDOEC, Jesus College, Cambridge, and becoming the first South African being awarded an honorary fellowship to the Society of Advanced Legal Studies in Brittain, as well as the American Order of the Coif.

Prof Henning will continue his partnership with the university in 2014, acting as dean and continuing his research.
