Conventional sex roles imply caring females and competitive males. The evolution of sex role divergence is widely attributed to anisogamy initiating a self‐reinforcing process. The initial asymmetry in pre‐mating parental investment (eggs vs. sperm) is assumed to promote even greater divergence in post‐mating parental investment (parental care). But do we really understand the process? Trivers [Sexual Selection and the Descent of Man 1871–1971 (1972), Aldine Press, Chicago] introduced two… Expand
Coevolution of parental investment and sexually selected traits drives sex-role divergence
Sex-role evolution theory attempts to explain the origin and direction of male–female differences. A fundamental question is why anisogamy, the difference in gamete size that defines the sexes, hasExpand
Sex roles and the evolution of parental care specialization
TLDR
The model predicts that efficient care specialization broadens the conditions under which biparental investment can evolve in lineages that historically had uniparental care, and contributes towards explaining widespread phylogenetic inertia in parenting and mating systems. Expand
Individual variation in parental care drives divergence of sex roles
TLDR
It is argued that all these results are caused by the emergence of individual variation in parental care strategies, a factor that was hitherto largely neglected in sex-role evolution theory. Expand
Sex differences in parental care: Gametic investment, sexual selection, and social environment
TLDR
No evidence for the gametic investment hypothesis is found, and sexual selection correlated with parental sex roles, because the male share in care relative to female decreased with both extra‐pair paternity and frequency of male polygamy. Expand
Evolution of male strategies with sex-ratio–dependent pay-offs: connecting pair bonds with grandmothering
TLDR
Using a difference equation model, the relative pay-offs for three competing male strategies (dependant care, multiple mating, mate guarding) in response to changing adult sex ratios are explored. Expand
Ecological determinants of sex roles and female sexual selection
TLDR
Research on the flower-feeding bushcricket Kawanaphila nartee has underscored the importance of ecology to reproduction by showing that food availability can affect the operational sex ratio and thus sex roles, indicating that sex roles are not necessarily fixed but rather respond plastically to environmental factors. Expand
Sexual conflict in mammals: consequences for mating systems and life history
TLDR
The potential for sexual conflict in mammalian mating systems is highlighted by exploring why males and females are selected to mate with multiple partners and by considering the shared characteristics of mammalian reproductive biology that may lead to predictable patterns of conflict over parental investment. Expand
Sexual Selection Determines Parental Care Patterns in Cichlid Fishes
TLDR
The hypothesis that sexual selection determines parental care patterns in Tanganyikan cichlid fishes is supported using a proxy of sexual selection based on mating system, sexual dichromatism, and dimorphism data. Expand
Adaptive sex allocation in anticipation of changes in offspring mating opportunities.
TLDR
Evidence is provided that mosquitofish (Gambusia holbrooki) populations possess a suitable life history: some autumn-born females bred alongside their own offspring, while such overlap was rare or absent for spring- born females and for all males. Expand
Not all sex ratios are equal: the Fisher condition, parental care and sexual selection

TLDR
It is suggested that it is more fruitful to understand the combined effect of the MSR and mortality rates while caring and competing than that of the ASR itself, and argued that the AsR does not have a causal role in the evolution of parental care. Expand

The Evolution of Parental Care in the Context of Sexual Selection: A Critical Reassessment of Parental Investment Theory
TLDR
It is shown that the classic ESS model, which contrasts parental care with offspring desertion, violates the necessary relationship between mean male and female fitness, and is discussed whether inferences about the evolution of sex differences in parental care can hold if the ESS theory on which they are based contains internal contradictions.

MORTALITY COSTS OF SEXUAL SELECTION AND PARENTAL CARE IN NATURAL POPULATIONS OF BIRDS
  • A. Liker, T. Székely

TLDR
The results challenge the traditional explanation of female‐biased avian mortalities, because evolutionary changes in female care were unrelated to changes in mortality bias. Expand
Mortality Patterns, Sex Ratios, and Parental Investment in Monogamous Birds
TLDR
A subject of great interest to students of animal mating systems over the past 15 years has been parental investment, a concept that includes parental care and the cost of gametes and has been modified to apply to clutches or broods of offspring. Expand
SEXUAL SELECTION WHEN FERTILIZATION IS NOT GUARANTEED
  • H. Kokko, J. Mappes
  • Biology, Medicine
  • Evolution; international journal of organic evolution
  • 2005
TLDR
It is suggested that changes in choosiness between populations, and in particular between virgin and mated females, offer an efficient way to test the hypothesis that male limitation form a selection for female traits that improve their mating rate. Expand
Experimental reversal of courtship roles in an insect
TLDR
It is confirmed and shown that an increase in food from a low level results in a change from role-reversal to the typical roles, which supports the theory that variation in relative male parental investment controls sexual differences. Expand
Unifying and Testing Models of Sexual Selection
TLDR
This work reviews evolutionary explanations for the relationship between anisogamy, potential reproductive rates, parental care, sex roles, and mate choice, and considers other forms of selection that can make females mate nonrandomly. Expand
EVOLUTIONARY PATHWAYS IN SHOREBIRD BREEDING SYSTEMS: SEXUAL CONFLICT, PARENTAL CARE, AND CHICK DEVELOPMENT
TLDR
The results are more consistent with the sexual conflict hypothesis than the parental investment hypothesis, and it is shown that chick development constrains the evolution of both parental care and mate competition. Expand
Sexual selection and the potential reproductive rates of males and females
TLDR
It is shown that among species where males care for the young, the sex with the higher potential reproductive rate competes more intensely for mates than thesex with the lower potential rate of reproduction. Expand
MALE VERSUS FEMALE MATE CHOICE: SEXUAL SELECTION AND THE EVOLUTION OF SPECIES RECOGNITION VIA REINFORCEMENT
  • M. Servedio
  • Biology, Medicine
  • Evolution; international journal of organic evolution
  • 2007
TLDR
This work addresses whether male mate choice is likely to evolve as a mechanism of premating isolation leading to species recognition, driven by the process of reinforcement, and demonstrates that although under many conditions stronger premates isolation evolves under female mate choice, reinforcement may indeed occur via male matechoice alone.

TLDR
A simulation model using the relationship between fecundity and number of mates to estimate sexual selection gradients and includes a trade‐off between paternal investment and sperm competition ability challenges previous thinking about the role of sperm competition in sex‐role reversal. Expand
