Robert Hazen, Research Scientist, Carnegie Geophysical Laboratory and Professor of Earth Sciences at George Mason University, will speak at the Geological Lecture Hall, 24 Oxford Street in Cambridge on Tuesday, March 12, beginning at 6 pm. The concept of evolution by natural selection has long been a lightning rod for anti-science rhetoric. Such attacks are usually aimed at the biological realm, but Darwin’s opponents must now face evidence that complex evolving systems also drive phenomena beyond life science, such as the diversification of minerals on earth. Part of the Evolution Matters Lecture Series, supported by a generous gift from Drs. Herman and Joan Suit. Free and open to the public. Geological Lecture Hall, 24 Oxford Street. Free event parking for evening lectures in the 52 Oxford Street garage.
