The Genetical Theory of Natural Selection
Mathematical formalization of natural selection
Along with Wright's work, this book established the mathematical foundations of population genetics. Fisher's treatment of random fluctuations in allele frequency contributed to what became known as the Wright-Fisher model.
Provides the theoretical basis for understanding the interplay between deterministic selection and stochastic drift in evolution, directly applicable to understanding when organizational strategy matters versus when random events dominate outcomes.
Key Findings from Fisher (1930)
- Mathematical formalization of natural selection
- Foundation for the Wright-Fisher model of population genetics
- Quantitative framework for understanding evolutionary dynamics
- Sexual selection can create self-reinforcing feedback loops
- Preferences can be arbitrary yet drive extreme trait development
- Runaway selection operates independently of survival fitness
- Traits can become exaggerated far beyond survival utility
