Mate choice by males has been documented in many taxa including fruit flies (Drosophila spp.). It is still unclear, however, whether male mate choice varies much with age and one cannot readily predict the direction of change in male choosiness with age. We compared mate choice in young (1 day old) and mature (4 days old) male fruit flies (Drosophila melanogaster). Young males spent much less t...

Modern humans have inherited the mating strategies that led to the success of their ancestors. These strategies include long-term mating, short-term mating, extra-pair mating, mate poaching, and mate guarding. This article presents empirical evidence supporting evolution-based hypotheses about the complexities of these mating strategies. Since men and women historically confronted different ada...

This research set out to find out the mate selection criteria among single female teachers. This qualitative study was carried out via thematic analysis approach. Using purposive sampling method, 15 single female teachers aged 18 to 30 years old were identified in Tehran and fifteen semi-structured interviews were conducted. The interviews were recorded, transcribed and then were analyzed using...

In terms of health and healthcare cyberspace and virtual reality can be used differently and for different purposes and consequently create different outcomes. The three main areas which we shall discuss here are: 1) cyberspace as provider of health information and self-help resources, since the anonymity cyberspace provides is particularly important in the highly stigmatized field of psychiatr...

Sexual isolation is a critical form of reproductive isolation in the early stages of animal speciation, yet little is known about the genetic basis of divergent mate preferences and preference cues in young species. Heliconius butterflies, well known for their diversity of wing color patterns, mate assortatively as a result of divergence in male preference for wing patterns. Here we show that t...

This paper begins with a long-term view of the development of cyberspace. This includes a brief examination of the worldview of a 16th-century mapmaker and over 4000 years of development from the early massive bureaucracies of Babylon and Egypt to the current day. This discussion shows that cyberspace is becoming an everyday experience and we need to design tools to help people navigate electro...
