Handicap 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 ...

متن کاملThe Handicap Process Favors Exaggerated, Rather than Reduced, Sexual Ornaments
Why are traits that function as secondary sexual ornaments generally exaggerated in size compared to the naturally selected optimum, and not reduced? Because they deviate from the naturally selected optimum, traits that are reduced in size will handicap their bearer, and could thus provide an honest signal of quality to a potential mate. Thus if secondary sexual ornaments evolve via the handica...
