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:
Biology
- Increasing size as observed in Dinosaurs and ancient insects
Society
- Conspicuous consumption (to signal status similar to peacock plumage)
- Charity (to signal social competence)
- Extensive form of economic reproduction
