Sexual selection is one of the earliest areas of interest in evolutionary biology. And yet, the evolutionary history of sexually dimorphic traits remains poorly characterized for most vertebrate lineages. Here, we report on evidence for the early evolution of dimorphism within a model mammal group, the pinnipeds. Pinnipeds show a range of sexual dimorphism and mating systems that span the extremes of modern mammals, from monomorphic taxa with isolated and dispersed mating to extreme size… Expand
Sexual selection on skeletal shape in Carnivora
TLDR
The hypotheses that carnivorans exhibit sexual dimorphism in skeletal anatomy that is reflective of greater specialization for physical aggression in males relative to females and that thisDimorphism is associated with the intensity of sexual selection are tested. Expand
Solitary meat-eaters: solitary, carnivorous carnivorans exhibit the highest degree of sexual size dimorphism
TLDR
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.

A Total Evidence Phylogenetic Analysis of Pinniped Phylogeny and the Possibility of Parallel Evolution Within a Monophyletic Framework
TLDR
Results suggest the pinniped stem may be expanded to include additional fossil arctoid taxa, including Puijila, Potamotherium, and Kolponomos, and provide further support for prolonged freshwater and nearshore phases in the Evolution of pinnipeds, prior to the evolution of the extreme level of aquatic adaptation displayed by extant taxa.

Evidence for the independent acquisition of aquatic specializations in pinnipeds (seals, sea lions, and walruses): insights from the study of the phylogenetic position, locomotor behaviour, and description of the stem pinniped, Puijila darwini
TLDR
A biomechanical analysis, using functional limb indices of extant carnivorans to predict locomotory modes in extinct taxa, confirms the aquatic adaptations of Puijila, and identifies it as a forelimb-dominated swimmer, and provides strong support for pinniped monophyly. Expand
Cope's rule and the evolution of body size in Pinnipedimorpha (Mammalia: Carnivora)
TLDR
The evolutionary history of pinnipeds does not follow Cope's rule, and it is suggested that the pinniped body size increase was driven by passive diversification into vacant niche space, with the common ancestor of Pinnipedimorpha occurring near the minimum adult body size possible for a marine mammal. Expand
The earliest mustelid in North America
TLDR
The significance of the relatively small size of this new mustelid as it relates to predictions based on increased aridification of the palaeoclimate and the expansion of open habitats in the Oligocene is discussed. Expand
Taxonomic implications of morphometric analysis of earless seal limb bones
Fossil Phocidae (earless seals) are mostly known from isolated postcranial material, forcing researchers to rely upon humeri and femora for the diagnosis of taxa and reconstruction of phylogeny.Expand
The role of social structure and kin associations in the mating system of the polygynous New Zealand sea lion (Phocarctos hookeri)
TLDR
This research aimed to determine whether interactions between male relatives influence male reproductive success, as well as the role of female mate choice in determining the genetic relatedness of mating pairs, an important factor for subsequent offspring fitness. Expand
Insights on the Dental Evolution of Walruses Based on New Fossil Specimens from California
ABSTRACT Twelve new specimens of fossil walruses are described from four Miocene units in California. The new material represents five taxa: (1) a specimen from the Santa Margarita Formation referredExpand
New Data on the Early Odobenid Neotherium mirum Kellogg, 1931, and Other Pinniped Remains from the Sharktooth Hill Bonebed, California
TLDR
The mandibular morphology of the odobenid Neotherium mirum is described in detail, adding further support for the presence of this taxon in the middle Miocene of California and represents the earliest evidence of trans-Pacific dispersal in pinnipeds. Expand

THE ORIGINS OF SEXUAL DIMORPHISM IN BODY SIZE IN UNGULATES
TLDR
A phylogeny of extant ungulate species, along with maximum‐likelihood statistical techniques, are used to provide a test of Jarman's hypothesis, which states that sexual size dimorphism evolved in a three‐step process. Expand
Phylogenetic analyses of sexual selection and sexual size dimorphism in pinnipeds
TLDR
The hypothesis that sexual size dimorphism in pinnipeds is the product of an exclusively male response to sexual selection is supported. Expand
The evolution of reproductive systems in pinnipeds
TLDR
The question of why otariid females reproduce in dense clusters instead of behaving as their relatives, the phocid females, that rear their pups in isolation or in small groups is addressed. Expand
Sexual-Size Dimorphism: Influence of Mass and Mating Systems in the Most Dimorphic Mammals
TLDR
Characteristics and testing for associations among the most dimorphic mammalian taxa—Macropodidae, Primates, Mustelidae, Pinnipedia, Elephantidae, Ruminantia, found that ruminants with tending and harem mating systems were moreDimorphic than those with territorial polygynous and monogamous mating systems.

The mating systems of pinnipeds and marine iguanas : convergent evolution of polygyny
TLDR
It is hypothesize that marginal males, through continuous sexual harassment of females that stay outside territories, have exerted pressure towards the evolution of female gregariousness. Expand
Sexual Size Dimorphism, Canine Dimorphism, and Male-Male Competition in Primates
TLDR
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.

A MODEL FOR THE EVOLUTION OF PINNIPED POLYGYNY

  • 1970
TLDR
The present paper undertakes to elaborate a verbal model based on ideas first suggested by Nutting (1891) and extended by Bertram (1940) and by Bartholomew (1952) and to place it more firmly in a documentable behavioral context. Expand
A Comparative Description of Dimorphism in Skull Ontogeny of Arctocephalus australis, Callorhinus ursinus, and Otaria byronia (Carnivora: Otariidae)
TLDR
It was found that dimorphism increased over ontogeny but was not due solely to allometric extrapolation, because different rates of development were found in some species, including northern fur seal and Callorhinus ursinus. Expand
Mammalian sexual dimorphism.
TLDR
The aim of this review is to discuss current knowledge relating to the evolution, benefits and costs of mammalian sexual dimorphisms and, where possible, draw conclusions that might be beneficial for the husbandry and propagation of mammals today. Expand
Sexual dimorphism and paleoecology in Teleoceras, a North American Miocene rhinoceros
TLDR
Sexual dimorphism is documented in 35 articulated adult skeletons, 24 females, and 11 males, of the Miocene rhinoceros Teleoceras major from Ashfall Fossil Beds, Nebraska, and the apparent herd structure and breeding-age sex ratio for the Ashfall herd suggests a behavioral ecology for T. major different from that of extantrhinoceroses.
