The resolution of evolutionary conflicts within species

Evolutionary conflicts of interest occur at all levels, scales and forms of biological organization. They are a fundamental component of the living world and range from conflicts between genetic elements and cells, to conflicts between the sexes and between competing individuals. Yet, the existence of admirably well functioning genomes, bodies, mating pairs and societies suggests that processes must exist to resolve or mitigate such conflicts. We organized this special feature 'The resolution of evolutionary conflicts within species' to encourage the flow of knowledge between fields that traditionally have often taken different approaches to study evolutionary conflicts. Contributed papers discuss data from bacteria, plants and animals (including humans) and present theory, molecular mechanisms and population dynamics of how conflicts are resolved in nature. Together, they contribute to a synthetic theory of conflict resolution.
