Primate Models for Australopithecine Sexual Dimorphism
Several different models of sexual dimorphism in the South African australopithecines are compared with sexual dimorphism in the living primates. Australopithecine dimorphism is placed in an evolutionary context, and contrasting trends in the hominid and pongid lineages are shown. Evidence suggesting that the australopithecines were an extremely polytypic taxon is presented, and a high level of...

متن کاملSexual Dimorphism in Mammals: Avian Models and Unanswered Questions
The degree of sexual dimorphism found in mammals ranges from species in which females are larger than males (Rails 1976a) to those in which males are much larger than females and possess striking secondary sexual characteristics which females lack. Although some work has been done on mammals, principally pinnipeds (Bartholomew 1970; Stirling 1975) and primates (Crook 1972), current theories as ...
متن کاملSexual size dimorphism in anurans.
Several hypotheses have been proposed to explain the direction and extent of sexual size dimorphism in anurans (in which males are usually smaller than females) as a result of sexual selection. Here, we present an analysis to test the hypothesis that sexual dimorphism in anurans is largely a function of differences between the sexes in life-history strategies. Morphological and demographic data...
متن کاملWnt Signaling in Sexual Dimorphism.
The embryonic gonad of Drosophila melanogaster begins to display sexually dimorphic traits soon after its formation. Here we demonstrate the involvement of a wnt family ligand, wnt-2, in the induction of these sex-specific differences. We show that wnt-2 contributes to the survival of a male-specific population of somatic gonadal precursor cells (SGPs), the male-specific SGPs that are located a...
