About Prof Dirk Opperman
Prof Dirk Opperman obtained his PhD in Biochemistry at the University of the Free State in 2008. This was followed by postdoctoral research on directed evolution with Prof Manfred T Reetz at the Max Planck Institute for Coal Research (Germany). In 2010, he was appointed in the Department of Microbiology and Biochemistry. He subsequently established structural biology at the UFS, and his current research focus lies at the interface of evolutionary and structure-function relationships of biocatalysts, and their application in green chemistry. He is an NRF B-rated researcher with co-authored papers in Science, Nature Communications, and Angewandte Chemie.
His research has been funded by both local and international organisations, ranging from industries such as SASOL to the Global Challenges Research Fund (GCRF, UK). He has a long-standing collaboration with researchers at the Delft University of Technology (TUDelft, the Netherlands) and is currently part of a European Research Area Network Cofund (ERA-NET Cofund) partnership on Food Systems and Climate (FOSC) that develops biocatalysts for upcycling waste.
Darwin lecture focuses on the genetic foundation of evolution

The Department of Genetics at the University of the Free State (UFS) recently made their contribution to the story of life and survival by presenting two lectures on The genetic foundation of evolution. Prof. Johan Spies, Head of the Department of Genetics at the UFS discussed the variation that was created by mutations and how this variation was enhanced by re-combination. He also pointed out that these methods contributed relatively little to the gene pool of a species and that the expansion of the gene pool primarily took place by means of chromosome evolution. The latter also contributed to the creation of isolation mechanisms to prevent hybridism. He further emphasised the multitude of deviations of mendelian heredity, which contributed to more variation within a species.
Prof. Paul Grobler, Associate Professor from this department, next pointed out how natural selection played a role to form new species. He used various examples to indicate how the process took its course, for example, lactose intolerance. He also reported out that the man on the street mostly believed that Darwin with his theory of the survival of the fittest meant that the physically strongest species would survive. It was more a case of the one that could reproduce the fastest and the most, that would survive, he stated.
Present at the occasion were, from left front: Ms Letecia Jonker, student, Prof. Grobler, Ms Paula Spies, lecturer at the Department of Genetics and Ms Zurika Odendaal, junior lecturer at the Department of Genetics; back: Prof. Spies.
