Three Charles Sturt University (CSU) professors will discuss the evolution of the ideas of Charles Darwin at a commemorative inaugural lecture and dinner in Bathurst on Tuesday 24 November. The inaugural Somerville Lecture is in honour of Professor Warren Somerville whose collection of world-class specimens is housed at the Bathurst Fossil and Mineral Museum in Howick Street, Bathurst. Professor Somerville will be one of the speakers, and the others are Professor Nick Klomp, Dean of the CSU Faculty of Science and Adjunct Professor David Goldney, a former lecturer and noted environmental consultant. “This will be a wonderful occasion, as it marks the 150th anniversary of the publication of Darwin’s On the Origin of Species on the 24 November 1859,” Professor Klomp said. “This book, as much as or more than any other, has changed the way we understand life on Earth. It is an honour to share the podium with Professor Somerville and Professor Goldney on this historic anniversary.”
