The purpose of this study was to investigate the impact of cyberspace on the lifestyle of young female students. The statistical population of the study was 90 students of Shahid Modarres Girls School of Chenaran city. Considering the number of the population, the complete enumeration method was used to distribute the questionnaire. In general, two major methods of library and field methods hav...

Simulations of the evolution of populations of diploid organisms showed that mate selection strategies which selected for “good genes” and strategies based on assortative mating, confer a much higher average fitness and higher evolutionary stability to populations than random mating. This advantage was more conspicuous the more genes per organism were simulated and the more genes were involved ...

Theoretical and empirical research indicates that sexual selection interacts with the ecological context in which mate choice occurs, suggesting that sexual and natural selection act together during the evolution of premating reproductive isolation. However, the relative importance of natural and sexual selection to speciation remains poorly understood. Here, we applied a recent conceptual fram...

Study of determinants of mate selection by animals has a long history in evolutionary biology and behavioural ecology. However, only during the past decade have investigators begun to conduct experiments exploring the various ways in which observation of the behaviour of others might influence mate selection. Here, we review both field and laboratory studies of behavioural processes that underl...

Millions of people use online dating sites each day, scanning through streams of face images in search of an attractive mate. Face images, like most visual stimuli, undergo processes whereby the current percept is altered by exposure to previous visual input. Recent studies using rapid sequences of faces have found that perception of face identity is biased towards recently seen faces, promotin...

Although mate preference research has firmly established that men value physical attractiveness more than women do and women value social status more than men do, recent speed-dating studies have indicated mixed evidence (at best) for whether people's sex-differentiated mate preferences predict actual mate choices. According to an evolutionary, mate preference priority model (Li, Bailey, Kenric...

Several experiments on children ́s participation in urban planning in Finland, Norway, Switzerland and Italy have demonstrated that young people are sharp analysts of their settings and creative producers of ideas for planning but the authorities are reluctant to expand their top-down, expert-based mode of urban planning to include new groups, such as young people. Will the application of intern...

Under sexual selection, mate preferences can evolve for traits advertising fitness benefits. Observed mating patterns (mate choice) are often assumed to represent preference, even though they result from the interaction between preference, sampling strategy and environmental factors. Correlating fitness with mate choice instead of preference will therefore lead to confounded conclusions about t...

This reflection writing was co-written by seven young people and three Master of Arts Child Youth Care (MA CYC) students from Ryerson University. Our centres around a Canadian youth-led initiative called First, developed as MA CYC placement due to the lack opportunities available during pandemic. First focused on creating safe interactive spaces in cyberspace for Through this reflection, we hop...
