Modern dating platforms have given rise to new dating and sexual behaviors. In the current study, we examine predictors of sending unsolicited explicit images, a particularly underexplored online sexual behavior. The aim of the current study was to explore the utility of dark personality traits i. Men, compared to women, were found to have higher explicit image scale scores, and both self-rated mate value and trait Machiavellianism were positive predictors of explicit image scale scores. Interestingly, there were no significant interactions between sex and these variables. Further, Machiavellianism mediated all relationships between other dark traits and explicit image scale scores, indicating this behavior is best explained by the personality trait associated with behavioral strategies.
Sex roles and mutual mate choice matter during mate sampling
Inter-sexual mate competition in three cultures
This blog Part 1 of 2 is a look at the future of sex, dating, and finding a mate. Dating in past generations was local and linear. You had access to a small number of potential mates based on where you lived, where you went to school and your social status. Go here for a great online dating infographic. Between and , there was exponential growth among heterosexual couples meeting online. See the green line in the first chart here. See the green line in the second chart here.
Sex, mate selection, and evolution
Darwinian sexual selection theory holds that mate selection occurs inter-sexually, and mate competition occurs intra - sexually for opposite-sex partners. We demonstrate that inter -sexual mate competition can also occur among humans at appreciable rates that vary by culture. In Canada, inter-sexual mate competition was both rare and inconsequential.
This advantage was more conspicuous the more genes per organism were simulated and the more genes were involved in the phenotype screened for mate selection. The results suggest that the evolutionary advantage of mate selection becomes evident only when the simultaneous adaptation of several genes are simulated. A cautionary lesson from the model is that mating is not likely to be random in nature and that mate selection may direct evolution by accelerating the exposure to natural selection of relevant traits. That is, models assuming random mating may not reflect what is happening in nature as sexual reproduction is probably associated with mate or gamete selection in most living organisms.
