The Black Queen hypothesis (BQH) is a reductive evolution theory which seeks to explain how natural selection can drive gene loss. In a microbial community, different members may have genes which produce certain chemicals or resources in a "leaky fashion" making them accessible to other members of that community. If this resource is available to certain members of a community in a way that allows them to sufficiently access that resource without generating it themselves, these other members in the community may lose the biological function involved in producing that chemical. Put another way, the black queen hypothesis is concerned with the conditions under which it is advantageous to lose certain biological functions. By accessing resources without the need to generate it themselves, these microbes conserve energy and streamline their genomes to enable faster replication.
