6:30 p.m., Thurs., Feb. 21 There are more described species of beetles than any other animal group. While many have remarked on their vast numbers, the origins of their diversity is still under investigation. This presentation will include a fossil-based approach to the history of beetles, presenting an overview of their fossil history, analyses of the strengths and weaknesses of the fossil record, and their patterns of origination and extinction. Specimens from the Museum's collection will be available for viewing.
