The Black Queen hypothesis (BQH) is a reductive evolution theory which seeks to explain how natural selection (as opposed to genetic drift) 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.
