Frequency-Dependent Adaptive Strategies Framework
Alternative strategies are maintained by frequency-dependent selection
The Frequency-Dependent Adaptive Strategies Framework suggests that alternative adaptive strategies can be maintained in populations through frequency-dependent selection. This framework provides a framework for understanding how different strategies, such as psychopathy or slow life-history strategies, can be maintained in populations.
- Alternative strategies can be maintained in populations through frequency-dependent selection.
- Frequency-dependent selection favors the evolution of assessment mechanisms that help individuals choose adaptive strategies.
- The payoffs of each strategy decrease as its frequency increases, relative to other strategies in the population.
- Identify Alternative StrategiesIdentify alternative adaptive strategies that may be maintained in populations, such as psychopathy or slow life-history strategies.Pro tipConsider the role of frequency-dependent selection in maintaining these strategies.WarningBe aware that the payoffs of each strategy decrease as its frequency increases.
- Evaluate Assessment MechanismsExamine how assessment mechanisms, such as self-assessment and decision-making, influence the choice of adaptive strategies.Pro tipConsider the role of evolved psychological mechanisms in shaping decision-making.WarningBe aware that the payoffs of each strategy decrease as its frequency increases.
Research has shown that psychopathy can be maintained in populations through frequency-dependent selection, illustrating the role of alternative strategies in shaping population dynamics.
The concept of frequency-dependent selection was introduced by Maynard Smith (1982) and D. S. Wilson (1998b) to describe the process by which alternative strategies are maintained in populations.
