物种形成可以是渐进的或突然的，涉及很少或很多遗传变化。推断产生这种模式的过程是困难的，并且可能需要考虑物种形成的紧急和非线性特性，例如当临界点的小变化对分化有很大影响时。临界点涉及正反馈和间接选择源于基因组区域之间的关联，由于初始条件和进化历史的影响，以及依赖于系统组件的模块化的双稳定性。这些特征与其他细胞、生态和社会系统中的突然“政权转移”有关。因此，用于理解其他复杂系统的工具可以卓有成效地应用于物种形成研究。
Speciation can be gradual or sudden and involve few or many genetic changes. Inferring the processes generating such patterns is difficult, and may require consideration of emergent and non-linear properties of speciation, such as when small changes at tipping points have large effects on differentiation. Tipping points involve positive feedback and indirect selection stemming from associations between genomic regions, bi-stability due to effects of initial conditions and evolutionary history, and dependence on modularity of system components. These features are associated with sudden 'regime shifts' in other cellular, ecological, and societal systems. Thus, tools used to understand other complex systems could be fruitfully applied in speciation research.
