Evolution and Conservation in Galapagos

Catalog description

The tiny remote islands of Galapagos have played a central role in the study of evolution. Not surprisingly, they have also been important to theory and practice in biodiversity conservation. The fascinating adaptations of organisms to the unusual, isolated ecosystems of the archipelago have left them particularly vulnerable to perturbations and introductions from the outside. Drawing on lessons learned from Darwin's time to the present, this seminar explores evolution, conservation, and their connection among the habitats and organisms of Galapagos. Using case-study material on tortoises, iguanas, finches, Scalesia plants, penguins, cormorants and more, we will explore current theory and debate about adaptation, speciation, adaptive radiation, sexual selection, and other topics in evolution. Similarly, we will explore the special challenges Galapagos poses today for conservation, owing to both its unusual biota and to the increasing impact of human activity in the archipelago. This course includes an intensive ten-day expedition to Galapagos at no additional cost to students. The goal of the expedition is both to observe firsthand many of the evolutionary adaptations and conservation dilemmas that we have read about, and to look for new examples and potential solutions. A chartered ship named MV La Pinta will serve as our floating classroom, dormitory, and dining hall as we work our way around the archipelago to visit seven different islands (Darwin visited four). For this portion of the class, undergraduates will be joined by a small group of Stanford alumni and friends in a format called a Stanford "Field Seminar." Because our class time on campus is limited to one week before travel, students will be required to complete all course readings over the summer. The course emphasizes student contributions and presentations. Students will be asked to lead class…
