Evolution of mutualisms: trends, models

There is no general theory of mutualism…; underlying problems revolve around explicitly defining vague terms, such as “alignment of interest”, and employing biologically realistic

currencies (i.e., costs and benefits) at biologically relevant scales of organizations.
