Relational developmental systems: a paradigm for developmental science in the postgenomic era.

This commentary argues that the anomalies suffered by the population behavior genetics paradigm are more widespread than suggested by Charney, including many made in the field of developmental science. Further, it is argued that, according to the criteria established by Kuhn, there is and has been available an alternative scientific paradigm that provides the formative context for Charney's postgenomic view. This is the relational developmental systems paradigm.
