Sexual selection plays several intricate and complex roles in the related processes of local
adaptation and speciation. In some cases sexual selection can promote these processes …

We review the current status of three well–established models (direct benefits, indirect
benefits and sensory drive) and one newcomer (antagonistic chase–away) of the evolution …

Sexual and asexual reproduction are found throughout the plant and animal kingdoms.
Asexual reproduction has its advantages, chief among which is that it does not require the …

This book presents the first unified conceptual and statistical framework for understanding
the evolution of reproductive strategies. Using the concept of the opportunity for sexual …

The genic capture hypothesis offers a resolution to the question of how genetic variation in
male sexually selected traits is maintained in the face of strong female preferences. The …

Sexual reproduction is associated with the evolution of anisogamy and sperm-producing
males and egg-laying females. The ensuing competition for mates has led to sexual …

Reproduction through sex carries substantial costs, mainly because only half of sexual
adults produce offspring. It has been theorized that these costs could be countered if sex …

Robert Trivers is a pioneering figure in the field of sociobiology. For Natural Selection and
Social Theory, he has selected eleven of his most influential papers, including several …

Sexual selection has manifold ecological and evolutionary consequences, making its net
effect on population fitness difficult to predict. A powerful empirical test is to experimentally …

Mathematical models have played an important role in the development of sexual selection
theory. These models come in different flavors and they differ in their assumptions, often in a …
