Evolution of sexual size dimorphism in tetrapods is driven by varying patterns of sex-specific selection on size A phylogenetic comparative analysis of male and female body size across tetrapods globally shows that directional change in size is usually greater in males but reveals different underlyin...
sexual selection n.Biology The process in nature by which individuals with certain traits, especially secondary sex characteristics such as colorful plumage and large antlers, are chosen more often for mating and thus pass those traits on to their offspring. ...
Sexual selection is selection due to differential access to quantity and quality of mates. One form of it, intersexual selection, is due to differential access to mates driven by the mate preferences of individuals of the other sex. The major question about sexual selection pursued in theoretical...
The evolution of sexual dimorphism in parasitic cuckoos: sexual selection or coevolution? Sexual dimorphism is ubiquitous in animals and can result from selection pressure on one or both sexes. Sexual selection has become the predominant explana... O, Krüger,NB Davies,MD Sorenson - 《Proceedings...
Darwin examined sexual dimorphism in animals, arguing that sexual selection was important in the evolution of such dimorphism. Sexual dimorphism in plants may have parallel causes and costs. The processes that contribute to sexual dimorphism may also lead to speciation and morphological differences among...
1,2 However, which male traits are involved in mating success and the genetic basis of these traits remains unclear. We used an experimental evolution approach to measure genome-wide responses of Ae. aegypti evolved in the presence and absence of sexual selection. These data revealed for the ...
Sexual selection can operate both intra- and inter-sexually, either sequentially or simultaneously (Table 1). During intrasexual selection, members of the same sex attempt to outcompete rivals, often during direct encounters. Intrasexual selection is typically responsible for the evolution of male arma...

selection and the evolution of beauty: two views Egbert Giles Leigh Jr* Open Access Abstract This is a review of Ryan's A Taste for the Beautiful and Prum's The Evolution of Beauty, two books that show how sexual selection by female choice can favor the evolution of ...
