Cryptic Sexual Selection - More Control Issues 1
Identifying the evolutionary processes that cause genetic and phenotypic divergence among species is one of the fundamental goals of evolutionary biologists. Darwin (1871) first pointed out that male traits such as plumage coloration, which he hypothesized to influence sexual selection, rapidly diverge among closely related species. In an earlier book (Sexual Selection and Animal Genitalia; Ebe...
متن کاملPostcopulatory fertilization bias as a form of cryptic sexual selection.
Males and females share most of their genetic material yet often experience very different selection pressures. Some traits that are adaptive when expressed in males may therefore be maladaptive when expressed in females. Recent studies demonstrating negative correlations in fitness between parents and their opposite-sex progeny suggest that natural selection may favor a reduction in trait corr...
متن کاملSexual selection by cryptic female choice on male seminal products - a new bridge between sexual selection and reproductive physiology.
Selection clearly focuses on differences in reproduction, but studies of reproductive physiology generally have been carried out in a near vacuum of modern evolutionary theory. This lack of contact between the two fields may be about to change. New ideas indicate that sexual selection by cryptic female choice has affected the evolution of products in male semen that influence female reproductiv...
متن کاملChoosy Females Exploring the role of cryptic female choice in sexual selection and battles over paternity
'he image of two males I engaged in a dramatic battle over the right to mate with a female is a staple of television nature documentaries. Such male-male competition leads to intrasexual selection among males•evolutionary selection for traits that increase a male's ability to compete with other males for reproductive access to females. But females are not necessarily passive participants in the...
متن کاملMore compatible with 'cryptic miliary tuberculosis'.
More compatible with 'cryptic miliary tuberculosis' To the Editor—I read with interest the case report published by Shea and Ip titled " Pulmonary tuberculosis complicating asbestosis ". 1 On reading the details, I could not agree on the authors' interpretation of the findings and the diagnosis of asbestosis. While it is beyond doubt that the findings of calcified pleural plaques point towards ...
