Which sex should care for offspring is a fundamental question in evolution. Invertebrates, and insects in particular, show some of the most diverse kinds of parental care of all animals, but to date there has been no broad comparative study of the evolution of parental care in this group. Here, we test existing hypotheses of insect parental care evolution using a literature‐compiled phylogeny of over 2000 species. To address substantial uncertainty in the insect phylogeny, we use a brute force… 
The evolution of parental care diversity in amphibians
It is shown that egg attendance, arguably one of the simplest care behaviours, is gained and lost faster than any other care form, while complex adaptations, like brooding and viviparity, are lost at very low rates, if at all.
Sex roles and the evolution of parental care specialization
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.
Patterns of parental care in Neotropical glassfrogs: fieldwork alters hypotheses of sex‐role evolution
It is discovered that a brief period of maternal care is widespread and occurs in species previously thought to lack care, and this change is associated with substantial increases in care levels – a pattern supporting the hypothesis that male‐only care evolved via constraints on maternal expenditure.
Where are all the moms? External fertilization predicts the rise of male parental care in bony fishes
It is suggested that moving control of fertilization outside of the female reproductive tract raises male confidence in parentage and increases the potential for paternal care, highlighting that in an aquatic environment in which fertilization is external, paternal care is an effective reproductive strategy.
Sex-biased parental care and sexual size dimorphism in a provisioning arthropod
This study reveals that such costs can be associated with the evolution of dimorphism, and this should be investigated in other clades where parental care costs differ between sexes and species.
Contribution of males to brood care can compensate for their food consumption from a shared resource
Test the hypothesis that male contribution to biparental brood care has a beneficial effect on offspring fitness but that this effect can be masked because the male also feeds from the shared resource, and shows that a mouse carcass prepared by two Nicrophorus beetles is lighter, which can influence offspring fitness when food availability is limited.
Sexual selection of male parental care in giant water bugs
The results suggest that sexual selection plays an important role in maintaining elaborate paternal care in giant water bugs, but the importance of egg-bearing by males in female mate choice varies among species.
Coevolution influences the evolution of filial cannibalism, offspring abandonment and parental care
This work uses a mathematical framework to explore how co-occurrence and coevolution among care, abandonment and cannibalism can influence the life-history conditions under which care is expected to evolve and suggests that in some cases, the evolution of parental care can be inhibited by offspring abandonment and filial cannibalism.
Polyandrous bee provides extended offspring care biparentally as an alternative to monandry based eusociality
It is suggested that the multiple-mating strategy of these bees increased the amount of time for interactions between the sexes, and this longer period of potential interaction supported the origin of biparental care.


The evolution of male and female parental care in fishes
The predominance of male parental care in fishes is not explained by males deriving greater benefits from care, but by males paying smaller future costs, and males thus accrue a greater net fitness advantage from parental care.
The evolution of parental care in insects: the roles of ecology, life history and the social environment
Insects are uniquely suitable for experimental and comparative research on the complex interplay between ecology, life history, and the social environment, and how these social interactions may in turn be influenced by ecological factors such as food availability or population density is discussed.
Patterns of parental care in invertebrates
The origins and transitions of extended care in invertebrates are confined primarily to post-fertilization traits that increase offspring fitness, beyond the temporary housing and passage of the fertilized egg within the female.
The Evolution of Paternal Care with Overlapping Broods
This work presents a model of parental care with overlapping broods in which males can mate and guard simultaneously, even though there is a trade‐off between these two activities and derives quantitative estimates of fitness for different strategies for two species of assassin bugs with male and female uniparental care and shows that the model predicts the correct form of care for both species.
A cost of polygyny is unlikely to drive a female care strategy to fixation on its own; however, if caring males suffer a cost of lost mating opportunities then a cost-of-polygyny may destabilize male care and result in the evolution of uniparental female care.

The laboratory has formalized Williams’s Principle into the relative value theorem and found that its application to fishes, the taxa with the most diverse patterns of parental care, can help to explain which sex provides care and how much.
Evolutionary transitions in parental care and live bearing in vertebrates.
In the numerous taxa that display live bearing by females, including teleosts, elasmobranchs, squamate reptiles and invertebrates, it is found that live bearing has always evolved from a lack of care.
Sexual selection and the evolution of exclusive paternal care in arthropods
The results suggest parallels between prezygotic nuptial gifts and exclusive postzygosis paternal care and support the hypothesis that, in arthropods, male behaviours that enhance female reproductive success either directly by releasing females from the fecundity constraints of maternal care or indirectly by identifying mates with superior genes are traits on which sexual selection has acted.
Parental Care Trade‐Offs and Life‐History Relationships in Insects
It is proposed that the metabolic demands of multiple offspring must scale with species body size more steeply than the parent’s provisioning capacity, resulting in larger females laying fewer eggs.
