In primates that are highly sexually dimorphic, males often reach maturity later than females, and young adult males do not show the size, morphology, and coloration of mature males. Here we describe extended male development in a hominin species, Paranthropus robustus. Ranking a large sample of facial remains on the basis of dental wear stages reveals a difference in size and robusticity between young adult and old adult males. Combined with estimates of sexual dimorphism, this pattern…

Estimates of body mass dimorphism for four hominin taxa are compared to assess changes in male and female size to illustrate the potential for considering howDimorphism changes through time, rather than simply focusing on the magnitude of size dimorphistan in isolation.

Sexual Size Dimorphism in Australopithecus : Current Understanding and New Directions

This chapter addresses concerns and possibilities for future analyses that relate to these confounding effects, and goes on to present the current understanding of size dimorphism within Australopithecus, as well as discussing specific methodologies for measuring relative size variation within fossil taxa.

Sexual dimorphism in Homo erectus inferred from 1.5 Ma footprints near Ileret, Kenya

The results indicate that East African Homo erectus was moreDimorphic than modern Homo sapiens, although less so than highly dimorphic apes, suggesting that the Ileret footprints offer a unique window into an important transitional period in hominin social behavior.

Substantial but Misunderstood Human Sexual Dimorphism Results Mainly From Sexual Selection on Males and Natural Selection on Females

It is argued that sex differences in adipose arise mainly from natural selection on women to accumulate neurodevelopmental resources, similar to those seen in primates where sexual selection, arising from aggressive male mating competition, has produced high levels of dimorphism.

Body Size, Size Variation, and Sexual Size Dimorphism in Early Homo

The range of size variation in Homo habilis/rudolfensis and Homo erectus matches or even is less than that seen in geographically restricted samples of living anthropoid primates, which underscores the critical necessity of improving comparisons of size among fossils and establishing an adequate comparative database of living species.

Digit ratios predict polygyny in early apes, Ardipithecus, Neanderthals and early modern humans but not in Australopithecus

The results suggest that digit ratios represent a supplementary approach for elucidating the social systems of fossil hominins, indicating increased androgenization and possibly higher incidence of polygyny in the early anatomically modern human Qafzeh 9 and Neanderthals.

Sexual Size Dimorphism, Canine Dimorphism, and Male-Male Competition in Primates

A phylogenetic reconstruction of the evolution ofDimorphism, including fossil hominins, indicates that the modern human condition is derived, and suggests that at least some behavioral similarities with Pan associated with dimorphism may have arisen independently, and not directly from a common ancestor.

Drimolen cranium DNH 155 documents microevolution in an early hominin species

An approximately 2-million-year-old male Paranthropus robustus cranium from Drimolen Main Quarry in South Africa refutes influential ideas of sexual dimorphism in this taxon and instead suggests local microevolution within robust australopiths.

Fossil Hominins, the Bipedal Primates

Mandibular development in Australopithecus robustus.

An important role of the postnatal period for mandibular shape development in this species is demonstrated, by comparing its ontogenetic series with a sample of recent humans, examining age-related size variation in 28 linear measurements.




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,

Sexual dimorphism in the face of Australopithecus africanus.

Resampling methodology (bootstrapping) is used here to establish that A. africanus has a greater craniofacial size range than chimpanzees or modern humans, a range which is best attributed to a moderately high degree of sexual dimorphism.

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.

Sexual dimorphism in primate evolution.

Understanding of the behavioral/ecological correlates of growth and development, and of the expression of dimorphism as a function of separate changes in male and female traits, offers great potential for inferring evolutionary changes in behavior over time.

Behavioral ecological implications of early hominid body size

The energetic requirement of the expanded brain may imply altered feeding strategies in both the "robust" australopithecine and Homo lineages.

The evolution of female social relationships in nonhuman primates

Evidence in support of the ecological model is reviewed and the power of alternative models that invoke between-group competition, forced female philopatry, demographic female recruitment, male interventions into female aggression, and male harassment are tested.

Socioecology and the ontogeny of sexual size dimorphism in anthropoid primates.

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.

Life history in male mandrills (Mandrillus sphinx): physical development, dominance rank, and group association.

Adult males were always the most social, and the most brightly colored males, but were not necessarily the largest males present, and alpha male tenure was related to group demography, with larger numbers of rival adult males and maturing adolescent males reducing the time a male spent as alpha male.

Balancing Costs and Opportunities: Dispersal in Male Baboons

A model of dispersal tendency is presented in order to explicate the ways in which differences in population density, predation risk, and the distribution of mating opportunities among groups might result in complex dispersal patterns that are consistent with both the results of the present study and the disparate empirical reports in the literature.

Understanding sexual dimorphism in living primates is important for interpreting the biological and taxonomic significance of variation in the primate fossil record. In the past two decades, there
