A complete resource including a biography, chronology, examples of Wallace's published work, quotes, and interviews.
Resource presents multiple digital formats of this literary text. You can read about the famous scientist's life in his own words, as he recalled his thoughts and actions for his children.
Biology 2e is designed to cover the scope and sequence requirements of a typical two-semester biology course for science majors. The text provides comprehensive coverage of foundational research and core biology concepts through an evolutionary lens. Biology includes rich features that engage students in scientific inquiry, highlight careers in the biological sciences, and offer everyday applications. The book also includes various types of practice and homework questions that help students understand—and apply—key concepts. The 2nd edition has been revised to incorporate clearer, more current, and more dynamic explanations, while maintaining the same organization as the first edition. Art and illustrations have been substantially improved, and the textbook features additional assessments and related resources.

In honor of Darwin's 200th birthday and the 150th anniversary of the publication of "The Origin of the Species," Cornell has put together an extensive collection of Darwin's work during the last two decades of his life.
This resource is an online companion of museum-mounted exhibition about Darwin and his revolutionary theory. It covers Darwin's upbringing, influences, and discoveries employing a rich mix of media: text, photographs, videos, sound files, primary source artifacts, and more.
This video segment from Evolution: "Darwin's Dangerous Idea," together with interviews with Daniel Dennett and James Moore, depicts Darwin struggling with publicizing his revolutionary theory. [6:34]
This group of letters is a sample of the extensive correspondence Darwin carried on with a wide group of friends and colleagues as he collected evidence to support his theory of evolution by natural selection. From Charles Darwin's Letters: A Selection 1825-1859.
