Sexual dimorphism in Upper Palaeolithic hand stencils
Sexual roles in deep prehistory are among the most intriguing puzzles still to solve. Here the author shows how men and women can be distinguished by scientific measurement in the prints and stencils of the human hand that occur widely in Upper Palaeolithic art. Six hand stencils from four French caves are attributed to four adult females, an adult male, and a sub-adult male. Here we take a ste...
متن کاملQuantifying the potential for sexual dimorphism using upper limits on Bateman gradients
Sex differences in the correlation between number of offspring and number of mates likely drive much of the evolution of morphological and behavioral sexual differences. These correlations have traditionally been represented by slopes from regressions of number of offspring on number of mates (Bateman gradients). Typically the Bateman gradient is assumed to be large for males and zero for femal...
متن کاملReduced Skull Sexual Dimorphism in a Local Sheep Breed
This study estimated the magnitude of sexual dimorphism in a relict sheep from Catalunya (NE Spain), called Fardasca,using geometric morphometric techniques. For these analyses, a total of 18 skull specimens (2 adult males and 16 females) were studied. Our results suggest that the breed is not cranially dimorphic, so sex determination using landmarks described here as criteria is likely to yiel...
متن کاملManipulation of feeding regime alters sexual dimorphism for lifespan and reduces sexual conflict in Drosophila melanogaster
Sexual dimorphism for lifespan (SDL) is widespread, but poorly understood. A leading hypothesis, which we test here, is that strong SDL can reduce sexual conflict by allowing each sex to maximize its sex-specific fitness. We used replicated experimental evolution lines of the fruit fly, Drosophila melanogaster, which had been maintained for over 360 generations on either unpredictable 'Random' ...
