General admission tickets are on sale now and are limited, so please purchase your tickets soon. 

This year's Kimbel Lecture is part of a three-day celebration of the 50th anniversary of the discovery of "Lucy,"—the 3.2-million-year-old fossil skeleton, discovered by Johanson in Ethiopia in 1974. 

IHO Founding Director Donald Johanson will engage you with the story of "Lucy's" discovery, the controversies of naming a new species, and how this small but complicated ancient human ancestor changed the way we think about how humans developed on Earth. Johanson is also a strong advocate for the human species to rekindle our sense of responsibility for the natural world in today's climate and environmental challenges.

This lecture series was begun in 2022 to honor the legacy of former IHO Director William H. Kimbel. To donate directly to the Bill Kimbel Impact Fund, go to this secured giving website.

General admission tickets ($43 per person) are available at the Mesa Arts Center online box office.
