We review the current status of three well–established models (direct benefits, indirect
benefits and sensory drive) and one newcomer (antagonistic chase–away) of the evolution …

Sexual selection has a reputation as a major cause of speciation, one of the most potent
forces driving reproductive isolation. This reputation arises from observations that species …

The past decade has seen a profound change in the scientific understanding of
reproduction. The traditional view of reproduction as a joint venture undertaken by two …

Evolutionary genomic studies find that reproductive protein genes, those directly involved in
reproductive processes, diversify more rapidly than most other gene categories. Strong …

Mathematical models have played an important role in the development of sexual selection
theory. These models come in different flavors and they differ in their assumptions, often in a …

Modeling of RA Fisher's ideas about the evolution of male ornamentation using quantitative
genetics began in the 1980s. Following an initial period of enthusiasm, interest in these …

The sensory bias model of sexual selection posits that female mating preferences are by-
products of natural selection on sensory systems. Although sensory bias was proposed 20 …

Stabilizing selection has been predicted to change genetic variances and covariances so
that the orientation of the genetic variance-covariance matrix (G) becomes aligned with the …

The Hamilton-Zuk hypothesis, that parasite-host coevolution can maintain heritable variation
in fitness, has inspired a very successful research program on sexual selection on signals of …

Recent work on sexual selection and sexual conflict has explored the influence of indirect
effects on the evolution of female mating behaviour. It has been suggested that the …
