Peter R. Girguis, Professor of Organismic and Evolutionary Biology, Department of Organismic and Evolutionary Biology at Harvard University, will speak on Thursday, April 13 at 6:00 pm in the Science Center, Hall D, 1 Oxford Street, as part of the Harvard Museum of Natural History’s Evolution Matters Lecture Series, supported by a generous gift from Drs. Herman and Joan Suit. The discovery of microscopic life forms in the seventeenth century led to humankind’s understanding of microbes as the biochemical innovators of our world. Microbes have evolved exotic metabolisms that enable them to live in seemingly inhospitable places, and they inhabit nearly every animal and plant on Earth. Peter Girguis will lead a virtual tour of ocean microbial life and discuss how marine microbes influence the evolution of all life on Earth, even playing a role in the geological and geochemical composition of our planet. Free parking is available at the 52 Oxford Street Garage. Free and open to the public.
