A fundamental assumption of adaptive explanations of female attractiveness is that bodily features that males judge as attractive reliably signal youthfulness, healthiness, and fertility or female mate value. One of the bodily features, waist-to-hip ratio (WHR), is a reliable indicator of a female’s reproductive age, sex hormone profi le, parity and risk for various diseases. Systematic variati...
This study aimed to investigate the effect of social comparison on self-perception and mate preferences. For this purpose, 225 undergraduate student participants provided their self-perception before and after evaluating descriptions of stimuli subjects specifically developed with high or low levels of physical, social and status related attributes. Participants also provided a description of t...
Correlated evolution of mate signals and mate preference may be constrained if selection pressures acting on mate preference differ from those acting on mate signals. In particular, opposing selection pressures may act on mate preference and signals when traits have sexual as well as nonsexual functions. In the butterfly Colias philodice eriphyle, divergent selection on wing color across an ele...

Obesity in children and young people is a significant public health issue. It can be associated with adverse health, economic and social implications. It is argued that preventing obesity needs adaptation to a healthy lifestyle, which includes behavioral modification, reduction in sedentary behavior, changes in nutrition, managing stress and increased...
Why do females of many species mate with more than one male? One of the main hypotheses suggests that female promiscuity is an insurance mechanism against the potential detrimental effects of inbreeding. Accordingly, females should preferably mate with less related males in multiple or extrapair mating. Here we analyse paternity, relatedness among mating partners, and relatedness between parent...
A computational study is conducted to evaluate the hypothesis that mate selection is the evolutionary origin of communication. A population of neural networks is evolved for two cooperative tasks mate selection and prey capture. Simple codes developed for mate selection serve as an effective stepping stone for prey capture but not vice versa. Mate selection followed by an additional prey captur...
