In sum then, there are good reasons to be cautious about the use of informational terminology in thinking about development. But it is also possible to over-estimate the strength of the connection between informational conceptions of development and the idea that genes play a uniquely important role in development. There are ways of defending the idea that genes play a special role while acknowledging the interactive character of development. Moreover, an ambitious use of informational concepts is not confined to those within mainstream biological thinking. Eva Jablonka and Marion Lamb defend quite heterodox views of inheritance and evolution, while basing key parts of their work—including an advocacy of “Lamarckian” ideas—around informational concepts (Jablonka and Lamb 2005). They suggest that one of the useful features of informational descriptions is that they allow us to generalize across different heredity systems, comparing their properties in a common currency. In addition, one of the present authors has used informational concepts to distinguish between the evolutionary role of genes from that of other inherited factors whilst demonstrating the evolutionary importance of non-genetic inheritance (Sterelny 2004, 2011). So in various ways, an informational point of view may facilitate discussion of unorthodox theoretical options, including non-genetic mechanisms of inheritance.
