Evolution, the history of life, encompasses diverse areas of study - from the origin of life and its subsequent historical record to the molecular and populational concepts that explain these events. Biology students, often daunted by the sophisticated and detailed information needed for their specialties, will appreciate the opportunity to look at the nature of life through the broad lens of evolution. To help students understand that all biological phenomena derive from evolutionary relationships, Dr. Strickberger's Evolution, Second Edition, provides a sweeping introduction that covers the chronology and mechanisms of evolution. Various chapters are devoted to topics that include the historical development of evolutionary thought, cosmological and geological events, evolution of genetic systems and molecular pathways, and accounts of organisms from plants to humans. In studying the history of life, students will begin to recognize the interrelatedness of many scientific fields.
