Abstract Although it has been the subject of verbal theory since Darwin, the evolution of morphological trait allometries remains poorly understood, especially in the context of sexual selection. Here we present an allocation trade‐off model that predicts the optimal pattern of allometry under different selective regimes. We derive a general solution that has a simple and intuitive interpretation and use it to investigate several examples of fitness functions. Verbal arguments have suggested…

Why the static allometry of sexually-selected traits is so variable: the importance of function.
- Environmental ScienceIntegrative and comparative biology
- 2019
The arguments in favor of this "functional allometry" hypothesis are summarized and a comparative test of its predictions indicate that sexual traits have the allometric slopes predicted, regardless of which body part bears the structure.
ALLOMETRIC CONSTRAINTS AND THE EVOLUTION OF ALLOMETRY
- Biology, Environmental ScienceEvolution; international journal of organic evolution
- 2014
It is argued that the hypothesis of strongly constrained static allometric slopes remains viable, and it is found that static allometries often predict evolutionary allometry on the subspecies level, but less so across species.
Allometry, sexual selection and evolutionary lines of least resistance shaped the evolution of exaggerated sexual traits within the genus Tyrannus

Variational properties hold a fundamental role in shaping biological evolution, exerting control over the magnitude and direction of evolutionary change elicited by microevolutionary processes that…
Allometry and sexually dimorphic traits in male anurans
- Biology, PsychologyJournal of evolutionary biology
- 2011
Although there is evidence of positive allometry in male secondary sexual traits of several species and populations, not all nonsexual traits were isometric or exhibited negative allometry, and the results indicate that larger traits in the populations that were studied were not associated with greater allometric slopes.
Allometry, sexual selection, and evolutionary lines of least resistance shaped the evolution of exaggerated sexual traits within the genus Tyrannus
- BiologybioRxiv
- 2021
Evidence of amplified divergence via the co-option and reorientation of allometric shape variation involved in a sexual selection process that repeatedly drove morphology along a historically favoured direction of cladogenetic evolution is presented.

Artificial selection on allometry: change in elevation but not slope
- BiologyJournal of evolutionary biology
- 2012
This study is the first artificial‐selection experiment that directly tests the evolvability of static allometric slopes, and suggests that the allometric elevation is more evolvable than the allometry slope, this latter representing a potential constraint on adaptive trait evolution.
Is allometry of sexual traits adaptive? A field test with territorial damselflies
- Biology
- 2015
Investigation of whether the allometry of two sexual traits is related to male mating success and survival in two species of damselflies shows that allometry does not seem to be adaptive.
Evolutionary allometry reveals a shift in selection pressure on male horn size
- BiologyJournal of evolutionary biology
- 2017
A nonlinear evolutionary allometry where the allometric slope decreased with increasing species body mass suggests either that horn size is limited by some constraints in the largest bovids or is no longer the direct target of sexual selection in very large species.

Across species, the degree of forcep allometry did increase with forcep exaggeration, and the relevance of positive allometry to reliable signalling is discussed.
Evolutionarily stable strategies of age-dependent sexual advertisement
- EconomicsBehavioral Ecology and Sociobiology
- 1997
The model shows that an increase in the expression of the sexually selected trait over several years is an evolutionarily stable strategy under a wide range of situations, so that a correlated preference for old age can emerge through a viability indicator mechanism.
The scaling and selection of sexually dimorphic characters: an example using the Marbled Teal

It is shown how the scaling in Marbled Teal can be used to study the selective forces responsible for dimorphic morphological characters, using the monochromatic Marbling Teal Marmaronetta angustirostris as an example.
The lek paradox and the capture of genetic variance by condition dependent traits
- BiologyProceedings of the Royal Society of London. Series B: Biological Sciences
- 1996
This paper offers a resolution to the lek paradox and rests on only two assumptions; condition dependence of sexually selected traits and high genetic variance in condition, which lead inevitably to the capture of genetic variance into sexually selected trait concomitantly with the evolution of condition dependence.

It is argued that scaling relationships are best viewed as reaction norms, and that the evolution of exaggerated morphological traits results from genetic changes in the slope and/or shape of these scaling relationships.

A review of the literature indicates a substantial lack of empirical evidence for these various mechanisms and highlights the need for experimental studies that specifically address the fitness costs of being large at the ecological, physiological, and genetic levels.

A significant fit is found to a statistical model for the identification of dimorphisms in Forficula auricularia and, for all species examined, morphs differed in the slope and/or elevation of the allometric relationship between body size and forcep length.
Beetle Horn Dimorphism: Making the Best of a Bad Lot
- BiologyThe American Naturalist

This study of the dimorphic horned dynastine beetle Podischnus agenor Oliver shows that the behavior and ecology of minor males differs from that of major males in ways which suggest that the minor form is a facultative adaptation designed to reduce direct competition with major males, and thus to compensate partially for the competitive disadvantage resulting from the minors' smaller size.

Results of experiments for estimating the intensity of sexual and viability selection on wing length in a recently captured population of Drosophila melanogaster support an equilibrium model in that the standardized response to viability selection was opposite in sign and similar in magnitude to the estimated response due to sexual selection.
