Would that not just be a tipping point in genetic diversity? Once you reach a certain level of complexity in one lineage you get exponentially more variation possible. Likewise, compound that from earlier lineage break aways that are now also reaching a tipping point in their own complexity. In other words, it's just an exponential situation under prime conditions for new species to emerge.
