We investigated the moderating influence of individual differences in women’s sociosexuality on romantic preferences within three specific relationship contexts. Female participants were presented with four prospective mates, varying in their ambition and attractiveness, and were asked to rate interest in these targets as short-term sexual partners, as casual dating partners, and as long-term r...

At first glance, color preferences might seem to be the most subjective and context-dependent aspects of color cognition. Yet they are not. The present study compares color preferences of women and men from an industrialized and a remote, nonindustrialized culture. In particular, we investigated preferences in observers from Poland and from the Yali in Papua, respectively. Not surprisingly, we ...

Female mate preferences for ecologically relevant traits may enhance natural selection, leading to rapid divergence. They may also forge a link between mate choice within species and sexual isolation between species. Here, we examine female mate preference for two ecologically important traits: body size and body shape. We measured female preferences within and between species of benthic, limne...

Diverging sexual communication systems can lead to the evolution of new species that no longer recognize each other as potential mates. The coevolution of male and female components of sexual communication is facilitated by physical linkage between genes underlying signals and preferences. By crossing two closely related Hawaiian crickets (Laupala kohalensis and Laupala paranigra) with vastly d...

The recent incorporation of sexual selection theories into the rubric of Evolutionary Psychology has produced an important framework from which to examine human mating behavior. Here we review the extant empirical and theoretical work regarding heterosexual human mating preferences and reproductive strategies. Initially, we review contemporary Evolutionary Psychology’s adaptationism, including ...

Exotic Becomes Erotic: Explaining the Enigma of Sexual Orientation Daryl J. Bem Cornell University In this address, I outline my “Exotic-Becomes-Erotic" theory of sexual orientation (Bem, 1996) , which provides the same basic account for both opposite-sex and same-sex erotic desire—and for both men and women. It proposes that biological variables do not code for sexual orientation per se but fo...

The joint evolution of female mating preferences and secondary sexual characters of males is modeled for polygamous species in which males provide only genetic material to the next generation and females have many potential mates to choose among. Despite stabilizing natural selection on males, various types of mating preferences may create a runaway process in which the outcome of phenotypic ev...

Multiple cues, across multiple sensory modalities, are involved in mate choice in a wide range of animal taxa. This multiplicity leads to the prediction that, in adaptive radiations, sexual isolation results from divergence in multiple dimensions. However, difficulties in directly measuring preferences and detecting multiple effects limit our ability to empirically assess the number of independ...

Ornamental secondary sexual traits are hypothesized to evolve in response to directional mating preferences for more ornamented mates. Such mating preferences may themselves evolve partly because ornamentation indicates an individual's additive genetic quality (good genes). While mate choice can also confer non-additive genetic benefits (compatible genes), the identity of the most 'compatible' ...

It is commonly assumed that natural selection imposed by predators is the prevailing force driving the evolution of aposematic traits. Here, we demonstrate that aposematic signals are shaped by sexual selection as well. We evaluated sexual selection for coloration brightness in populations of the poison frog Oophaga [Dendrobates] pumilio in Panama's Bocas del Toro archipelago. We assessed femal...
