If you happen to be in the Michigan State University area on March 2, Richard Dawkins will be speaking at the Wharton Center:
The talk is sponsored by the WorldView speaker series and the EEBB (Ecology, Evolutionary Biology, and Behavior) program. Tickets are required, but are free to anyone with an MSU ID. I got my tickets last week, and the floor seating is sold out. This is the same lecture series that brought in E.O. Wilson last Spring.
