title: Evolutionary genetics: big effect of a small RNA.
abstract: A new study demonstrates that tissue-specific changes in the expression of a microRNA contribute to morphological variation in nature. This and other examples suggest that the evolution of microRNA-regulated gene networks may follow the same general principles as the more familiar regulatory networks controlled by transcription factors.
