Gene Flow in Natural Populations
TL;DR
Empirical validation of Nm = 1 threshold across multiple species
Comprehensive empirical review validating the Nm = 1 threshold across species. Documented how marine organisms with high larval dispersal show less local adaptation than species with limited mobility, providing evidence that gene flow prevents populations from adapting to local conditions.
This supports the book's argument that high talent migration prevents firms from developing distinctive capabilities suited to their specific competitive environment.
Key Findings from Slatkin (1985)
- Empirical validation of Nm = 1 threshold across multiple species
- High-dispersal marine species show reduced local adaptation
- Low-dispersal species show strong local adaptation
- Gene flow measurement methods reviewed and compared
