Variation and Fixity in Nature: The Meaning of Diversity and Discontinuity in the World of Living Things and Their Bearing on Creation and Evolution

In nature we observe both diversity and discontinuity among all plants and animals. Living things cannot be arranged in a continuous unbroken series from simple to complex nor can one variant be traced through a continuous series to a markedly different variant. What do these two phenomena - diversity and discontinuity - say to us about the origin and meaning of living things? How do the observable facts fit in with the various theories of origins? What are the strengths and weaknesses of each? These questions and more are addressed in this major contribution to the literature on creation and evolution.
