Sexual selection and mate choice.
The past two decades have seen extensive growth of sexual selection research. Theoretical and empirical work has clarified many components of pre- and postcopulatory sexual selection, such as aggressive competition, mate choice, sperm utilization and sexual conflict. Genetic mechanisms of mate choice evolution have been less amenable to empirical testing, but molecular genetic analyses can now ...
متن کاملMate availability and unmarried parent relationships.
Theoretically, a shortage of males in a local marriage market may influence the formation, quality, and trajectory of unmarried parent relationships. To test these hypotheses, I combine city-level sex ratio data from the U.S. census with microdata on unmarried couples who recently had a child from the Fragile Families and Child Wellbeing study. A shortage of men in a marriage market is associat...

Get out of your chair and go look at some animals behaving. I hope that spring is in the air so that you can see animals courting and mating. Look at insects, birds, mammals, or reptiles. Go to the beach and look at the fiddler crabs. So sad if the dead of winter has set in and animals aren’t engaged in mating rituals. Look at fish in an aquarium. Go to a tropical fish store and look at a tank ...
متن کاملSexual Selection and Condition-Dependent Mate Preferences
The last decade has witnessed considerable theoretical and empirical investigation of how male sexual ornaments evolve. This strong male-biased perspective has resulted in the relative neglect of variation in female mate preferences and its consequences for ornament evolution. As sexual selection is a co-evolutionary process between males and females, ignoring variation in females overlooks a k...
متن کاملIndividual Differences in Moral Disgust Do Not Predict Utilitarian Judgments, Sexual and Pathogen Disgust Do
The role of emotional disgust and disgust sensitivity in moral judgment and decision-making has been debated intensively for over 20 years. Until very recently, there were two main evolutionary narratives for this rather puzzling association. One of the models suggest that it was developed through some form of group selection mechanism, where the internal norms of the groups were acting as path...
