Semester Offered: Spring 1 unit(s) In this course we study the methods and principles employed in deciphering the geologic history of Earth and the development of life on the planet. We emphasize the geologic evolution of the North American continent and the main features of the fossil record. Students learn to recognize the patterns of both biologic and tectonic evolution of Earth through time, from the Archean to the present. Woven throughout the course is consideration of the history of geologic thought through examination of the ideas of James Hutton, Charles Lyell, Charles Darwin, and Alfred Wegener. Jill Schneiderman.
