Genomic divergence can cause reproductive isolation between species. The molecular mechanisms underlying reproductive isolation can thus reveal which genomic features evolve rapidly and become unstable or incompatible in hybrids. In a recent paper in Nature, Gibeaux et al. (2018) report paternal genome instability and metabolic imbalance in hybrids between frog species.
