The modest goals of the Berkeley Geochronology Center include "establishing the history of the earth, its inhabitants and its interactions with the rest of the solar system." It facilitates collaborations between researchers around the world, examining the geologic record embedded in rocks and other earth materials. Along the way, they learn much about human evolution, climate change and the way the earth has changed over its history.
