This analysis investigates the ontogeny of body size dimorphism in apes. The processes that lead to adult body size dimorphism are illustrated and described. Potential covariation between ontogenetic processes and socioecological variables is evaluated. Mixed‐longitudinal growth data from 395 captive individuals (representing Hylobates lar [gibbon], Hylobates syndactylus [siamang], Pongo pygmaeus [orangutan], Gorilla gorilla [gorilla], Pan paniscus [pygmy chimpanzee], and Pan troglodytes…

The present study shows that intergeneric variation in size is largely a consequence of differences among species in the rate of body weight growth, and suggests links between ontogenetic patterns and social and ecological variables.

Investigation of these alternative ontogenetic pathways indicates that multiple factors influence the ontogeny of sexual dimorphism in primates, and demonstrates the importance of ontogenetics and life history variation in primates.

The ontogeny of sexual dimorphism in free-ranging rhesus macaques.

The ontogeny of size dimorphism in rhesus macaques is achieved by bimaturism and a faster male growth rate, as an outcome of sex-specific growth strategies, and these results provide new data for understanding the development and complexities of primateDimorphism.

Much variation recorded by this study remains unexplained, providing additional evidence of the need to specially examine female ontogeny before primate body size dimorphism can be satisfactorily explained.

Although lowland and mountain gorillas do not appear to have evolved novel adaptations of the postcranium which correlate with differences in locomotor behavior, the present investigation establishes subspecies differences in ontogeny and sexual dimorphism which may be linked with ecological variation.

Sexual dimorphism in Australopithecus afarensis was similar to that of modern humans

These data eliminate some apparent discrepancies between the canine and skeletal size dimorphism in hominoids, imply that the species was not characterized by substantial sexual bimaturation, and greatly increase the probability that the reproductive strategy of A. afarensis was principally monogamy.

Ontogenic differences in sexual size dimorphism across four plover populations

The results suggest that adult SSD can emerge at different stages of development (prenatal, postnatal and post‐juvenile) in different populations of the same species, and discuss the proximate mechanisms that may underlie these developmental differences.

Patterns of sexual variation in hominoid mandibular morphology: a framework for interpreting the hominin fossil record

This work describes the phenotypical expression of sexual dimorphism in the mandible of six extant hominoid species, including humans, using geometric morphometrics and finds significant differences in how sexualDimorphism is expressed phenotypically even amongst closely related species with small divergence times.

Morphological analyses of the teeth and locomotor skeletons of pongids and humans also corroborate the Ferris et al. branching sequence, and a variety of shared, unique features of the karyotypes of African apes lend strong credence to this phylogeny.

Sexual dimorphism in mammals is not entirely satisfactorily explained by the models that are advanced to account for it among birds. This may be because species‐specific styles of being dimorphic,

Ontogenetic approaches to sexual dimorphism in anthropoids

It is suggested that an investigation of the ontogenetic bases of sexual dimorphism can provide new insights and information unobtainable from studies concerned only with adult endpoints, and it is demonstrated that although all dimorphic anthropoids appear to be characterized by somebimaturism, the degree varies significantly.

A re-evaluation of subspecific variation and canine dimorphism in woolly spider monkeys (Brachyteles arachnoides).

It is suggested that the level of geographic variation in woolly spider monkey canine dimorphism is not consistent with subspecific status, and the lack of clear distinctions between populations in the degree of canineDimorphism complicates assessments of behavioral variation between these populations.
