To close season 10, co-hosts Brian Bartel and Dale Basler welcome back Dr. Sean B. Carroll - award-winning scientist, writer, and educator. Dr. Carroll's new book, The Serengeti Rules, examines the fundamental question of how life works as he uncovers the rules that determine the number of species in an environment and the diversity within that community. What this molecular biologist learns in the field provides insights into evolution, conservation and functional environmentalism that affect us all on the local and global level. Listen to the show to hear how Dr. Carroll shares compelling stories of science that include exploration with epic adventures, surprise, and even a little detective work in The Serengeti Rules.
