Invertebrate microRNAs (miRNAs) can suppress developmental variability that is caused by environmental and genetic variation. In this issue of Developmental Cell, Kasper et al. (2017) show that zebrafish miRNAs suppress variability in cardiovascular development during embryogenesis, providing insight into the conserved link between miRNAs and robustness.
