"Transitions and extinctions" was the topic of the latest lecture in the year long lecture series called "The story of life and survival" presented last week on the Main Campus of the University of the Free State (UFS) in Bloemfontein. The lecture was presented by Dr Jennifer Botha-Brink, a palaeontologist at the National Museum, and affiliated to the Department of Zoology and Entomology at the UFS.

She discussed the causes of mass extinctions and their effects on the world's organisms - an issue that may be relevant to us as human beings as we enter the next major mass extinction. Here are, from the left: Prof. Jo van As, Head of the Department of Zoology and Entomology at the UFS, Dr Botha-Brink and Mr Rick Nuttall, Director of the National Museum.
