The Handicap Principle Is an Artifact
The handicap principle is one of the most influential ideas in evolutionary biology. It asserts that when there is conflict of interest in a signaling interaction signals must be costly in order to be reliable. While in evolutionary biology it is a common practice to distinguish between indexes and fakable signals, we argue this dichotomy is an artifact of existing popular signaling models. Onc...
متن کاملSexual Signalling in an Artiicial Population: When Does the Handicap Principle Work? 1 Sexual Signalling and the Handicap Principle
Males may use sexual displays to signal their quality to females ; the handicap principle provides a mechanism that could enforce honesty in such cases. Iwasa et al. 1] model the signalling of inherited male quality, and distinguish between three variants of the handicap principle: pure epistasis, conditional, and revealing. They argue that only the second and third will work. An evolutionary s...

متن کاملHandicap principle implies emergence of dimorphic ornaments.
Species spanning the animal kingdom have evolved extravagant and costly ornaments to attract mating partners. Zahavi's handicap principle offers an elegant explanation for this: ornaments signal individual quality, and must be costly to ensure honest signalling, making mate selection more efficient. Here, we incorporate the assumptions of the handicap principle into a mathematical model and sho...
متن کاملDoes the handicap principle explain the evolution of dimorphic ornaments?
Many species are sexually dimorphic and, interestingly, males in some species are dimorphic themselves: some males develop weapons and ornaments, whereas others express rudimentary ornaments or none at all (horned beetles, Onthophagus taurus: Emlen, Lavine, & Ewen-Campen, 2007; Moczek & Emlen, 2000; bluegill sunfish, Lepomis macrochirus: Dominey, 1980; Gross & Charnov, 1980; ruffs, Philomachus ...
