An introduction to the series of digital biology textbooks that uses interactive elements and video. The series of seven books, in addition to this introduction, is available for free from iTunes and was developed by the E.O. WIlson Biodiversity Foundation. From the official webpage: To create Life on Earth, the E.O. Wilson Biodiversity Foundation brought together a team consisting of educators, writers, multimedia artists, 3D animators trained in science and cinema, and textbook professionals, led by naturalist Edward O. Wilson. The editorial team, headed by Morgan Ryan, worked in full partnership with the Boston-based scientific graphics company Digizyme, Inc, headed by Gaël McGill, PhD, with the goal of creating a cultural landmark—a portal that will introduce students to the grandest story there is, the story of life on Earth, from molecules to ecosystems, from the origin of life to the modern awareness that we control the environment we live in.
