LOS ANGELES — Millions of fossils fill the archival drawers at La Brea Tar Pits. For paleobotanist Dr. Regan Dunn, they provide clues that help her understand the interplay between climate, plants and animals. 'How animals evolve is a factor of the environment that they live in,' Dunn said. 'And most of the time, that has to do with plants and the plant cover.' For more than 55,000 years, La Brea Tar Pits has been preserving a richly diverse range of prehistoric plants and animals and thus attracts researchers from around the world.
