The application of molecular genetic techniques has revolutionized our view of avian mating
systems. Contrary to prior expectations, birds are only very rarely sexually monogamous …

The aim of this review is to consider the potential benefits that females may gain from mating
more than once in a single reproductive cycle. The relationship between non-genetic and …

▪ Abstract Extra-pair paternity (EPP) is extremely variable among species of birds, both in its
frequency and in the behavioral events that produce it. A flood of field studies and …

Research conducted in the last fifteen years has placed in question many of the traditional
conclusions scholars have formed about human female sexuality. Though conventional …

A previous study by the authors showed that the body scent of men who have greater body
bilateral symmetry is rated as more attractive by normally ovulating (non-pill-using) women …

The magnitude of the effect of good genes as a viability benefit accruing to choosy females
remains a controversial theoretical and empirical issue. We collected all available data from …

We describe the development and initial application of a semiautomated parentage testing
