This chapter advances a theory of the development of individual differences in reproductive strategies by drawing on the West–Eberhard model of switch-controlled systems. The first part of the chapter describes the concept of switch-controlled modular systems and their critical role in the development and maintenance of alternative reproductive strategies. This part also dicusses ultimate causation. The chapter asks: At an evolutionary level, how has the process of natural selection organized these modular systems? The second part of the chapter discusses the conditions under which natural selection favors regulation of alternative reproductive strategies through adaptive genetic variation versus conditional responsivity to developmental conditions.

Keywords:   individual differences, reproductive strategy, West–Eberhard model, switch-controlled modular systems, natural selection, adaptive genetic variation, conditional responsivity
