In my opinion for this to ful! ly come about the groups moldiness adhere to some type of inbreeding in gear up for the species to survive. And if so, would it non yield to the same gene only mix oer and over not to cause a new species nevertheless to create a mutation that would be phase out by natural selection. According to Johanson the following chart illustrates these rase of the model.
