Sexual dimorphism is commonly used to directly infer or support reconstructions of social behavior in early hominins. This is often done by comparing the magnitude of sexual size dimorphism to that seen in extant primates and extrapolating a likely social behavior. Such comparisons are of limited value, though, allowing only the inference of strong male–male competition when dimorphism is strong. Recent studies have begun to focus on the selective factors that impact female body size, and… 
Postcranial indicators of primate sexual dimorphism: implications for reconstructing fossil hominin sexual dimorphism and hominin palaeoecology
The sustained accuracy of sex estimation through the best skeletal metric discriminators makes discriminant function analysis a practicable method of classifying sex for fossil hominin specimens.
Estimating sexual size dimorphism in fossil species from posterior probability densities
The posterior density peak (pdPeak) method is introduced that utilizes the Bayesian inference to provide posterior probability densities of dimorphism levels and within-sex variance simultaneously and provides unbiased estimates ofDimorphism at levels lower than previously possible.

It is found that are territorial solitary and carnivorous carnivorans exhibited selection towards increased degree of male-biased SSD compared to other carnivoran with alternative social systems and diets, and the absence of Rensch’s rule across most carnivoran clades suggests a relaxation of the influences of sexual selection on SSD.
Pathways to paternal care in primates.
Evidence of paternal care and extended breeding bonds in owl monkeys, baboons, Assamese macaques, mountain gorillas, and chimpanzees is reviewed, suggesting that there are multiple pathways by which conditions conducive to male care can arise.

Interest in the evolution of human behavior has always featured large in evolutionary biology, challenging the imaginations not just of paleoanthropologists and archeologists, but also of virtually
Anthropological Prosociality via Sub-Group Level Selection
A novel mechanism, sub-group level selection (sGLS) is hypothesised by triangulating two pieces of data rarely considered by evolutionary biologists, and it is contended that sGLS supplied an exponential effect which was available to LCA who left the forest, but was not sufficiently available to any other primates.
Mate Choice and the Persistence of Maternal Mortality
The hypothesis that irrespective of the causes, the risks of all factors causing maternal mortality would be aggravated by disassortative mating, specifically male preference for younger females who are generally small statured and at higher risk of obstetric complications is entertained.
Was monogamy a key step on the hominin road? reevaluating the monogamy hypothesis in the evolution of cooperative breeding
This work evaluates whether the prevalence of cooperative breeding in contemporary human societies suggests a monogamous hominin past, and suggests that monogamy provides a general rule for explaining evolutionary transitions to cooperative breeding.
Great Ape Social Systems
For decades, the social systems of the great ape species were described as being fundamentally different, but long-term field studies have questioned this idea. Although orangutans seem to be less


Interpreting hominid behavior on the basis of sexual dimorphism.
A joint comparison of recent models for the behavioral correlates of both canine dimorphism and body sizeDimorphism of Australopithecus afarensis and A. robustus can be reconciled with a mating system characterized by low-intensity male-male competition.

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.
Sexual Dimorphism, the Operational Sex Ratio, and the Intensity of Male Competition in Polygynous Primates
A weight-corrected measure of sexual dimorphism and a biologically realistic assay of mating competition, the operational sex ratio, are employed to reexamine the factors favoring the evolution of sexual sizeDimorphism in primates and produce results consistent with the sexual selection hypothesis.
Relationship of sexual dimorphism in canine size and body size to social, behavioral, and ecological correlates in anthropoid primates
The degree of canine size dimorphism is closely related to the amount of male intrasexual selection in a given mating system; and the degree of body sizeDimorphism may be modified by selection pressure from factors such as habitat, diet, foraging behavior, antipredator behavior, locomotory behavior, and female preference.
Sexual selection and canine dimorphism in New World monkeys.
It is concluded that intermale competition among platyrrhine species is the most important factor explaining variations in canine dimorphism, and the significant effects of size and sizeDimorphism in some models may be evidence that natural selection also plays a role in the evolution of increased canine Dimorphism.
Allometry for Sexual Size Dimorphism: Pattern and Process in the Coevolution of Body Size in Males and Females
Sexual size dimorphism (SSD) is common in both plants and animals, and current evidence suggests that it reflects the adaptation of males and females to their different reproductive roles. When
Intrasexual competition and body weight dimorphism in anthropoid primates.
Re-evaluate variation in adult body weight dimorphism in anthropoids, testing the sexual selection hypothesis using categorical estimates of the degree of male-male intrasexual competition ("competition levels"), and test the hypotheses that interspecific variation in body weightDimorphism is associated with female body weight and categorical Estimates of diet, substrate use, and phylogeny.
Phylogenetic analyses of primate size evolution: the consequences of sexual selection
An independent contrast analysis of male and female size (log weight) showed that these are tightly correlated and that size dimorphism is not a simple allometric function of size, and the directional investigation indicates that the magnitude of change in haplorhine dimorphisms is larger after an increase in sexual selection than after a decrease.
Sexual dimorphism in weight among the primates: The relative impact of allometry and sexual selection
It is proposed that the overall size of a species determines whether theDimorphism will be expressed as size dimorphism,rather than in some other form, and that sexual selection due to differences in the reproductive potential of males and females is the primary cause of sexual Dimorphism.

It is suggested that sexual selection is the primary determinant of degree and pattern of sexual dimorphism in platyrrhines, but that there is also a dietary effect and natural selection may have some effect, although not the parameters analyzed here.
