Optimality Models and the Test of Adaptationism

The use of optimality models in the investigation of adaptation remains controversial. Critics charge that advocates of the optimality approach assume that the traits they analyze are optimal. Advocates of the approach deny this but admit to assuming that the traits have adaptive explanations. This controversy is part of the ongoing debate about adaptationism. We believe that this controversy remains unresolved in part because of ambiguity in the definition of adaptationism. In this article, we… Expand
Optimality modeling in a suboptimal world
It is argued that the centrality of these uses of optimality models ensures a continuing role for the optimality approach, regardless of the fate of adaptationism, and they account for the prominence of Optimality modeling in population biology. Expand
A Philosophical Evaluation of Adaptationism as a Heuristic Strategy

The productivity of adaptationist heuristics is demonstrated but also the deeper problematic aspects associated with the imperialistic tendencies of the strong account of MA are discussed. Expand
Constraining the adaptationism debate
This contribution to the adaptationism debate elaborates the nature of constraints and their importance in evolutionary explanation and argues that the adaptationism debate should be limited to theExpand
One of the most heated areas of controversy within contemporary evolutionary biology concerns adaptationism and the importance of natural selection relative to other evolutionary factors. BecauseExpand
Testing Adaptationism: A Comment on Orzack and Sober
The purpose here is to demonstrate that Orzack and Sober's thesis of what constitutes adaptationism is ill posed, and to state that the status of the "adaptationist program" does not stand or fall on the outcome of their project or the revision of it here. Expand
How (not) to test an optimality model.
This work describes how the test of an optimality model should be structured if the local optimality of the trait is to be assessed and how such a test can contribute to a test of adaptationism. Expand
Some Concerns Regarding Explanatory Pluralism: The Explanatory Role of Optimality Models
Optimality models are widely used in different parts of biology. Two important questions that have been asked about such models are: are they explanatory and, if so, what type of explanations do theyExpand
Debating the Power and Scope of Adaptation
How often should we invoke adaptation to explain the features of the biological world? Ideally, just as often as a history of natural selection explains the form and function of those features. ThisExpand
How to pursue the adaptationist program in psychology
In recent times evolutionary psychologists have offered adaptation explanations for a wide range of human psychological characteristics. Critics, however, have argued that such endeavors areExpand
The Historical Turn in the Study of Adaptation
  • P. Griffiths

A number of philosophers and ‘evolutionary psychologists’ have argued that attacks on adaptationism in contemporary biology are misguided. These thinkers identify anti-adaptationism with advocacy ofExpand


Evolution and the Theory of Games
  • J. M. Smith
  • Sociology, Computer Science
  • American scientist
  • 1976
It is beginning to become clear that a range of problems in evolution theory can most appropriately be attacked by a modification of the theory of games, a branch of mathematics first formulated by Von Neumann and Morgenstern in 1944 for the analysis of human conflicts. Expand
How to Carry Out the Adaptationist Program?

  • Biology
  • The American Naturalist
  • 1983
Even though the adaptationist program has been occasionally misapplied, particularly in an uncontrolled reductionist manner, its heuristic power justifies its continued adoption under appropriate safeguards. Expand
Evolutionary stability: States and strategies
Abstract Different aspects and modifications of the definition of an evolutionarily stable (ES) strategy that have been considered in the literature can be incorporated in a unifying concept whichExpand
Optimization Theory in Evolution
The basic structure of optimization arguments is outlined, and the possibility that some variation may be selectively neutral, and some structures maladaptive is discussed, as well as comment on criticisms made by Lewontin. Expand
The spandrels of San Marco and the Panglossian paradigm: a critique of the adaptationist programme
  • S. Gould, R. Lewontin
  • Biology, Medicine
  • Proceedings of the Royal Society of London. Series B. Biological Sciences
  • 1979
The adaptationist programme is faulted for its failure to distinguish current utility from reasons for origin, and Darwin’s own pluralistic approach to identifying the agents of evolutionary change is supported. Expand
The Optimization Research Program: Studying Adaptations by Their Function
This work develops as a scientific research program the essential assumptions used in applying optimization techniques to the study of adaptation and suggests that alternative hard cores might include the assumption of studies in quantitave genetics to the effect that genetics generally constrain adaptation at an evolutionarily stable equilibrium.

A Discussion of Evolutionarily Stable Strategies
Consideration of the question “What behaviours can be expected in stable biological populations?” leads first to a description of the classical ESS population model and determination of the two ESSExpand
Sampling theory for alleles in a random environment
A third sampling distribution is presented, showing that the properties of random-selection populations at equilibrium are indistinguishable from neutral-allele populations for observations made at a single time point, calling into question the claim that agreement of data with predictions of the neutral model argues against natural selection as an important factor for the maintenance of genetic variation.

Sex ratio polymorphism: The impact of mutation and drift on evolution
This paper addresses the question, which sex ratio will evolve in a population that is subject to mutation and drift and shows that false predictions of the stable population states might result from two simplifying assumptions. Expand
A Classification of Alternative Reproductive Behaviors and Methods for Field-testing ESS Models
A different scheme is suggested—devoid of ESS connotations—which classifies alternatives according to whether they represent genetic differences between individuals (genotypic versus phenotypic alternatives), whether the alternatives can be expected to manifest equal or unequal fitnesses, and whether individuals may switch back and forth between alternatives.
