Adaptationism and Optimality

A collection of new articles on natural selection
and its role in organic evolution

Steven Orzack and Elliott Sober, editors
Cambridge University Press, 2001

     We believe that developments over the last fifteen years or so in phylogenetic analysis, in our theoretical understanding of optimality and ESS models, in methods of testing models, as well as the dramatic increases in numbers of models and in tests of models, all have significantly increased our understanding of adaptationism and optimality. Yet many old and new questions remain unanswered. For these reasons, we have produced this integrated collection of the variety of views about these central issues in evolutionary biology. This book will be of interest to biologists "in the trenches" and to philosophers of biology who confront issues about adaptationism and optimality in their work.

Contents

David Baum and Mike Donoghue, A Likelihood Framework for the Phylogenetic Analysis of Adaptation

How distinct approaches to the historical study of adaptation can be unified
and how such a unification can contribute to a test of adaptationism.

 

Steven Orzack and Elliott Sober, Adaptation, Phylogenetic Inertia, and the Method of Controlled Comparisons

How phylogenetic inertia and natural selection relate to one another
and how adaptive and inertial hypotheses should be tested.

 

H. Kern Reeve and Paul Sherman, Optimality and Phylogeny: A Critique of Current Thought

How phylogenetic analyses relate to the debate
over adaptationism and optimality.
