This non-technical introduction to evolution, produced by the American Geological Institute in cooperation with the Paleontological Society, aims to help the general public gain a better understanding of one of the fundamental underlying concepts of modern science. Colorful photos, drawings, and illustrations complement the authors' conversational style as they discuss geologic time; change through time; Darwin's theory of evolution; evolution as a mechanism for change; the nature of species; the nature of theory; paleontology, geology, and evolution; and determining the age of fossils and rocks. Four "case study" examples from the fossil record - evolution of vertebrate legs, evolution of birds, evolution of mammals, and evolution of whales - are presented to provide a time perspective for understanding the evolution of life on Earth. The booklet contains straightforward definitions as well as discussions of complex ideas.
