Apparently, it's written all over your partner's face: Men with short, wide faces have higher sex drives and may be more likely to cheat. https://www.aol.com/article/lifestyle/2017/09/25/face-shape-may-reveal-if-youre-dating-a-cheater/23222179/ - [Science Says Nice Guys Have More Sex | Better | NBC News](https://evolutionlab.nipissingu.ca/science-says-nice-guys-have-more-sex-better-nbc-news/) - Human Evolution Lab | Recent research suggests altruists are more likely to get lucky with potential sex partners. https://www.youtube.com/watch?v=-AzLUlFXhkU - [Tina Piché Publishes](https://evolutionlab.nipissingu.ca/tina-piche-publishes/) - Human Evolution Lab | Congratulations to former lab student Tina Piché on her first publication based on her thesis work.

Former thesis student Brian Bird, and former lab coordinator SarahJayne Connick, will both be attending master’s programs at Laurentian University in the fall. Best of luck! - [Graduate Studies](https://evolutionlab.nipissingu.ca/graduate-studies/) - Human Evolution Lab | The Evolution Lab congratulates two former students on being accepted to graduate studies. Former thesis student Tina Piche will be attending Liverpool and Lab coordinator Marlena Pearson will be attending Ryerson University. Congratulations! - [Health Affecting Mating](https://evolutionlab.nipissingu.ca/health-affecting-mating/) - Human Evolution Lab | Across cultures, health is an important mating characteristic (Buss et al., 1990). Recent research shows that both men and women rank health as the fourth most important trait (out of 18) in a marriage partner, and that men and women rank health as the third most important trait (again, out of 18) in a partner - [Immune Function](https://evolutionlab.nipissingu.ca/immune-function/) - Human Evolution Lab | Signaling and cueing theories suggest that animals are sensitive to morphological features which might provide information about the genetic quality of a potential mate, especially as it pertains to the organism’s health and viability. Indeed, mating with an unhealthy partner confers a number of risks to both the individual and their offspring. Yet surprisingly little - [Morphology Augmentation](https://evolutionlab.nipissingu.ca/morphology-augmentation/) - Human Evolution Lab | Ornamentation is common in the natural environment, where successful displays to the opposite sex can lead to mating opportunity. We are studying the many ways human morphology can signal mate-value (Arnocky, Bird, & Perilloux, 2014), as well as how individuals alter their morphological displays through modern practices such as diet pills, skin tanning, and cosmetics - [Intrasexual Competition](https://evolutionlab.nipissingu.ca/intrasexual-competition/) - Human Evolution Lab | In sexually-reproducing species, both intersexual and intrasexual competition can bolster reproductive fitness (Darwin, 1859; 1871). We are exploring how competition is expressed in human behavior, with a focus on direct aggression (physical violence, threats), indirect aggression (gossiping, social exclusion) in both peer (Arnocky & Vaillancourt, 2012) and romantic relationships (Arnocky, Sunderani, Miller, & Vaillancourt, 2012). - [Operational Sex Ratios](https://evolutionlab.nipissingu.ca/operational-sex-ratios/) - Human Evolution Lab | The ratio of reproductively-viable males to females in a given population (i.e., the Operational Sex Ratio) can influence a host of mating-related behaviors. We are interested in examining how human behavior is sensitive to mate scarcity versus abundance. We have recently found that men and women primed with perceived mate-scarcity behave more aggressively toward an - [Mate Poaching](https://evolutionlab.nipissingu.ca/mate-poaching/) - Human Evolution Lab | Mate-poaching involves attempting to mate with someone who is already in an existing relationship. Mate-poaching is risky, with the possibility of retaliation from the cuckold or opprobrium from the social group. This begs the question: Why mate-poach, when there are so many eligible mates available? We are interested in understanding whether mate-poaching confers mating benefits - [Graduate Success](https://evolutionlab.nipissingu.ca/graduate-success-2/) - Human Evolution Lab | A big congratulations to former thesis student, Angela Ribout, for her recent acceptance into the School and Applied Child Psychology graduate program at the University of Calgary! - [Wendy Gomes Publishes](https://evolutionlab.nipissingu.ca/wendy-gomes-publishes/) - Human Evolution Lab | Congratulations to former lab student Wendy Gomes on her first publication based on her thesis work.
