It has long been suggested that tropical species are generally more colourful than temperate
species, but whether latitudinal gradients in organismal colourfulness exist remains …

Sexual selection is proposed to be a powerful driver of phenotypic evolution in animal
systems. At macroevolutionary scales, sexual selection can theoretically drive both the rate …

The duration of the developmental period represents a fundamental axis of life-history
variation, yet broad insights regarding the drivers of this diversity are currently lacking. Here …

Although evolutionary theory predicts an association between the evolution of elaborate
ornamentation and speciation, empirical evidence for links between speciation and …

Animal signals—involving combinations of acoustic, chemical, visual, and behavioral cues—
are among the most diverse traits in nature. Testing hypotheses about signal evolution has …

Sexual selection is thought to shape phylogenetic diversity by affecting speciation or
extinction rates. However, the net effect of sexual selection on diversification is hard to …

An overlooked source of variation in evolvability resides in the social lives of animals. In
trying to foster research in this direction, we offer a critical review of previous work on the link …

Morphology, habitat and various selective pressures (eg social and sexual selection) can
influence the evolution of acoustic signals, but the relative importance of their effects is not …

Sexual selection, one of the central pillars of evolutionary theory, has powerful effects on
organismal morphology, behaviour, and population dynamics. However, current knowledge …

Socio-sexual selection is predicted to be an important driver of evolution, influencing
speciation, extinction and adaptation. The fossil record provides a means of testing these …
