More about the speaker:

Tomas Vetrik received two scholarships from foreign countries during his PhD study. He spent one semester of his PhD study at the Vienna University of Technology in Austria, and two semesters at the Technion – Israel Institute of Technology. He was the only postgraduate student from Slovakia to receive a scholarship from the Israeli government in 2006. Tomas Vetrik joined the University of the Free State in 2014, after his postdoctoral research at the University of KwaZulu-Natal and working at the UniversityPretoria. His research area is graph theory. He is mainly focusing on the degree-diameter problem, graph indices, and metric dimension of graphs. He is an NRF-rated researcher and has produced about 75 research papers (approximately 25 of them as a single author).

Three PhD students and three MSc students have completed their studies under his supervision. He has presented seminar talks at 24 universities from 15 different countries.

Darwin lecture focuses on the genetic foundation of evolution

2009-05-22

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.
