Supplementary Reading 



Darwin's classic. The Origin of Species, is available in a number of modern editions 

 and is well worth sampling for its clear, logical arguments and wealth of examples. The 

 impact of the theory of evolution on Victorian England, and a vivid portrayal of Thomas 

 Huxley's championing of Darwin's theory, are presented in William Irvine's Apes, Angels 

 and Victorians. Henry Fairfield Osborn's From the Greeks to Darwin is an interesting 

 history of ideas on evolution. A good, nontechnical presentation of our current ideas on 

 evolution is found in G. G. Simpson, The Meaning of Evolution. Technical books on 

 special phases of evolution are Carter's Animal Evolution: A Study of Recent Views on its 

 Causes, Stebbins' Variation and Evolution in Plants, Simpson's The Major Features of 

 Evolution, which discusses the paleontologic and genetic aspects of evolution, Dobzhan- 

 sky's Genetics and the Origin of Species, which presents the Neo-Darwinian viewpoint of 

 the importance of natural selection, and Goldschmidt's The Material Basis of Evolution, 

 which gives the detailed argument for the importance of large mutations in evolution. 

 Theories of the origin of life are discussed in Oparin's The Origin of Life and in Blum's 

 Time's Arrow and Evolution. Two very readable, short discussions of the origin of life 

 are given by Melvin Calvin in Cliemical Evolution and the Origin of Life, and by George 

 Wald in The Origin of Life.
