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”.

Prof Naomi Morgan knighted by French Government
2015-02-02

Prof Naomi Morgan

Prof Naomi Morgan, lecturer at the UFS Department of Afrikaans and Dutch; German and French, received the prestigious Chevalier de l’Ordre des Arts et des Lettres award at the French Embassy in Pretoria on Monday 26 January 2015.

The Ordre des Arts et des Lettres (Order of Arts and Letters) is an Order of France, established on 2 May 1957 by the Minister of Culture, and its supplementary status to the Ordre national du Mérite was confirmed by President Charles de Gaulle in 1963. Its purpose is the recognition of significant contributions to the arts, literature, or the propagation of these fields.

Prof Morgan is being recognised for her translation work of plays such as ‘Oskar en die Pienk Tannies’, as well as translations of Afrikaans songs to French for the popular Afri-Frans compilation. The fact that the French Government gives such a highly-acclaimed award in recognition to the ‘art of translation’ is even more of an overwhelming honour to her than the personal achievement in itself.

The Chevalier (the Knighting) awarded to Prof Morgan is the third highest grade in the Order.

Prof Morgan now joins world-renowned individuals such as William Kentridge and Johnny Clegg on the list of foreign luminaries who have received this honour. Only two Literature Professors from South Africa – JM Coetzee and André P Brink – received this award in the past. During 1992, Brink received a Commandeur de l’Ordre des Arts et des Lettres and Coetzee was awarded the Chevalier de l’Ordre des Arts et des Lettres.

“I feel that an award like this is not only significant for me, but also to students who are busy with their studies and wondering: is there going to be recognition, what can one do with translation?” Prof Morgan said. “This is the biggest gift, the biggest gift anyone could ever give me. Now I ask for nothing more!”
