The Earth Through Time, 11th Edition, by Harold L. Levin and David T. King chronicles the Earth's story from the time the Sun began to radiate its light, to the beginning of civilization. The goal of The Earth Through Time is to present the history of the Earth, and the science behind that hsitory, as simply and clearly as possible. The authors strived to make the narrative more engaging, to convey the unique perspective and value of historical geology, and to improve the presentation so as to stimulate interest and enhance the reader's ability to retain essential concepts, long after the final exam.
Harold ("Hal") Levin began his career as a petroleum geologist in 1956 after receiving bachelor's and master's degrees from the University of Missouri and a doctorate from Washington University. His fondness for teaching brought him back to Washington University in 1962, where he is currently professor of geology and paleontology in the Department of Earth and Planetary Sciences. His writing efforts include authorship of seven edition of The Earth Through Time, four editions of Contemporary Physical Geology; Essentials of Earth Science and co-authorship of Earth: Past and Present, as well as eight editions of Laboratory Studies in Historical Geology; Life Through Time, and more recently, Ancient Invertebrates and Their Living Relatives.
For his courses in physical geology, historical geology, paleontology, sedimentology, and stratigraphy, Hal has received several awards for excellence in teaching. The accompanying photograph was taken during a lecture on life of the Cenozoic Era. The horse skull serves to illustrate changes in the teeth and jaws of grazing animals in response to the spread of prairies and savannahs during the Miocene and subsequent epochs.
