Missing concepts in natural selection theory reconstructions.

Area of Science:

• Philosophy of Biology
• Evolutionary Biology

Background:

• The term "fitness" in biology has multiple interpretations, notably ecological fitness and population genetics fitness.
• Clarifying these distinctions is crucial for understanding evolutionary theory.

Observation:

• The paper reconstructs the theory of natural selection as presented in Darwin's primary works.
• This reconstruction focuses on the historical application of the concept of ecological fitness.

Findings:

• A metatheoretical structuralist framework is employed to explicate ecological fitness.
• This approach offers a clearer understanding of fitness and its application across heterogeneous biological scenarios.
• It addresses the unique metatheoretical status of natural selection theory.

Implications:

• Provides a more robust framework for understanding natural selection and ecological fitness.
• Enhances the explanation of how fitness applies to diverse evolutionary contexts.
• Offers a novel perspective on the metatheoretical underpinnings of evolutionary theory.
