Figure 2. — Intragenomic arms races between the selfish genetic elements and the cellular machinery drive the evolution of hybrid incompatibilities. Interactions between selfish elements and host genomes co-evolve as selection favors selfish elements that can evade host defenses. This in turn triggers an evolutionary response favoring host variants that can defend themselves from selfish elements. The genes that are at the interface of these conflicts are predicted to diverge rapidly under selection, and can lead them to become incompatible between species.
