Fisherian Runaway in Different Systems

By Fisherian Runaway genetically oriented evolutionary biologists understand the effect that sexual selection favors the evolution of traits that are disadvantageous for survival. Male ornamentation like the peacock plumage are a typical example.

From fauceir perspective this is nothing unusual it results from imprecision in measuring resources during evolutionary progress. We observe similar phenomena everywhere:


  • Increasing size as observed in Dinosaurs and ancient insects


  • Conspicuous consumption (to signal status similar to peacock plumage)
  • Charity (to signal social competence)
  • Extensive form of economic reproduction
