Why have birds got multiple sexual ornaments?
SummaryMales of many animals have more than a single exaggerated secondary sexual character, but inter-specific variability in the number of ornaments has never been explained. We examine threeExpand

Do sexual ornaments demonstrate heightened condition-dependent expression as predicted by the handicap hypothesis?
The handicap hypothesis of sexual selection predicts that sexual ornaments have evolved heightened condition–dependent expression. The prediction has only recently been subject to experimentalExpand

Sexual Selection and Condition-Dependent Mate Preferences
The last decade has witnessed considerable theoretical and empirical investigation of how male sexual ornaments evolve. This strong male-biased perspective has resulted in the relative neglect ofExpand

THE EVOLUTION OF COSTLY MATE PREFERENCES I. FISHER AND BIASED MUTATION
Fisher's runaway process is the standard explanation of the evolution of exaggerated female preferences. But mathematical formulations of Fisher's process (haploid and additive diploid) show itExpand

A resolution of the lek paradox
Sexual traits are usually more phenotypically variable than non-sexual traits. We show that additive genetic variation is also higher in sexual traits, and often greater than in the same,Expand

CONDITION DEPENDENCE OF SEXUAL ORNAMENT SIZE AND VARIATION IN THE STALK‐EYED FLY CYRTODIOPSIS DALMANNI (DIPTERA: DIOPSIDAE)
Abstract We used the stalk‐eyed fly Cyrtodiopsis dalmanni to examine predictions made by condition‐dependent handicap models of sexual selection. Condition was experimentally varied by manipulationExpand

Causes of sex ratio bias may account for unisexual sterility in hybrids: a new explanation of Haldane's rule and related phenomena.
Unisexual hybrid disruption can be accounted for by interactions between sex ratio distorters which have diverged in the species of the hybrid cross. One class of unisexual hybrid disruption isExpand

THE EVOLUTION OF MATE PREFERENCES FOR MULTIPLE SEXUAL ORNAMENTS
Males of many species use multiple sexual ornaments in their courtship display. We investigate the evolution of female sexual preferences for more than a single male trait by the handicap process.Expand

In Fisher's model of sexual selection female mating preferences are not subject to direct selection but evolve purely because they are genetically correlated with the favoured male trait. But whenExpand
