Possible selective advantages, including some new ones, for hermaphroditism are reviewed. It is proposed that hermaphroditism should evolve under the following conditions: (a) where it is hard to find a mate; (b) where one sex benefits from being larger or smaller than the other; or (c) where there are small, genetically isolated populations. Some conceptual problems and a comparative means of study are discussed. The literature is reviewed to show the conditions under which hermaphroditism may… 
Why be an hermaphrodite?
TLDR
The basic argument of this paper is that the sex habit of a species is determined by selection acting on the number of offspring produced by individuals of different types.

TLDR
Darwin's theory of sexual selection provided the key to understanding sex switches, but it was not invoked until 1969 when it was conjoined with ideas about relative size influenced by the work of Bernhard Rensch.
Brooding and the evolution of hermaphroditism.
Hermaphroditism as a reproductive strategy for metazoans; some correlated benefits
Abstract The concept of hermaphroditism is examined, the terminology is reviewed, and several new terms are proposed: EUHERMAPHRODITISM for the occurrence together of eggs and sperm in the individual
Protogynous hermaphroditism in fishes of the family Scaridae
TLDR
Attempts to clarify the selective advantage of sequential hermaphroditism, which is now recognized as a widespread population phenomenon, have not always kept pace with histological and physiological studies.
Sex change and sexual selection
TLDR
Giselin (2) shifted the focus by suggesting that if members of one sex increase in fertility more rapidly with age than those of the other, then natural selection will favor a genotype whose individuals are all born into the sex that suffers less from being young.
Sexual adaptations to high density in hermaphrodites
TLDR
This approach can explain the presence of a number of obvious adaptations known from hermaphrodites, which cannot be explained by assuming that low density has been the rule in their evolutionary past.
Simultaneous hermaphroditism; cost and benefit.
Accessory male investment can undermine the evolutionary stability of simultaneous hermaphroditism
TLDR
It is explored how sexual selection on male accessory investments that offer a paternity benefit affects the evolutionary stable strategy SA in outcrossing, simultaneous hermaphrodites and across much of the parameter space, the model predicts male allocations well above 50 per cent.

Experimental and cytological studies on bisexual and hermaphrodite free‐living nematodes, with special reference to problems of sex
TLDR
Sexual instinct seems to be lacking in males of R. dolichura and R. elegans and certain peculiar males show developmental processes approaching those of hermaphrodites.
Functional Hermaphroditism and Self-fertilization in a Serranid Fish
TLDR
Mating behavior of pairs and groups of hermaphrodites shows two types of behavioral patterns involving different color changes.
ON THE EVOLUTION OF PARTHENOGENESIS IN LONCHOPTERA (DIPTERA)
TLDR
The purpose of this paper is to report work carried out on the dipterous genera Lonchoptera and Drosophila which bears on the forces and mechanisms that promote evolutionary change, and what must not happen if evolution is to occur.
Evidence of self-fertilization in certain species of barnacles
TLDR
From a very large number of observations on both Balanus balanoides (L.) and Elminius modestus Darwin there remains little doubt that in these two species copulation is necessary before eggs are brought into the mantle cavity where they are fertilized.
EVIDENCE FOR THE EXISTENCE OF HOMOZYGOUS CLONES IN THE SELF-FERTILIZING HERMAPHRODITIC TELEOST RIVULUS MARMORATUS (POEY)
TLDR
The transplantation test has been used to determine whether fish that had descended from the same wild-caught progenitor possess identical genotypes, and it has proved that hermaphrodites kept in isolation in aquaria, and their her maphrodite descendants keep in isolation ab ovo, have reproduced by self-fertilization.
LYCASTIS QUADRATICEPS, AN HERMAPHRODITE NEREID WITH GIGANTIC OVA
TLDR
Among the Annelida Polycha@ta the genus Ly castis in the family Nereid2e has the sfriking physiological pecu liarity that a majority of its known species are found living in fresh water as well as in the sea, a thing of rare occurrence in other families of the Polych@ta.
MULTIPLE MATING AND EFFECTIVE POPULATION SIZE IN CEPAEA NEMORALIS
TLDR
The rarity of fixation suggests that the effects of genetic drift are somehow reduced in most populations of Cepaea, and that the effective population size must be relatively small.
The patterns of sexuality and the classification of serranid fishes. American Museum novitates ; no. 2207
TLDR
The present paper describes the general structure of the serranid gonads that exhibit three types of hermaphroditism, and it is expected that additional patterns will be found.
REPRODUCTIVE MECHANISM OF UNISEXUAL AND BISEXUAL STRAINS OF THE VIVIPAROUS FISH POECILIOPSIS
TLDR
From preserved material collected within the range of strain "F," Miller was able to identify females with two types of dentition, one of these is considered to be the normal type in that the minute inner teeth are like those of the male.
Existence of Multiple Sex Genotypes in the Hermaphrodite Polychaete Worm Ophryotrocha puerilis siberti
TLDR
Ophryotrocha puerilis can be considered as an unbalanced hermaphroditic species because of its marked sex variability.
