Beginning with Darwin's work in the 1870s, this title selects the most important works from the discipline's first hundred years--44 classic papers--and presents them in facsimile, tracing the development of the field. These papers are classics because they either founded a line of investigation, established a basic method, or provided a new approach to an important research question. Copyright (C) Muze Inc. 2005.
