Model of speciation

WebThis chapter discusses two species models, which are diametrically opposed. The first, often called the 'biological species concept', defines species in terms of 'reproductive isolation', convinced that species arise when subsets of a population are split off and remain geographically isolated over evolutionary time. If and when such new species are … WebEven the first step of the model of ecological speciation, the divergent selection alone has not been demonstrated to occur.

WebLaboratory populations might serve as model systems. One can establish the conditions of the specific model under question and ask if the predicted divergence is observed. Mathematical models can address specific predictions about modes of speciation. Both of these “artificial” methods are important since they can identify what is possible.

It is related to the founder effect, where small living populations may undergo selection bottlenecks.
