WebOct 25, 2005 · Under the assumption that the divergence of mating preferences among populations is a key source of premating isolation, our results are consistent with the classic by-product model of allopatric speciation. In this model, new species arise as a side effect of natural selection adapting populations to their different environments [ 12, 23 – 25 ]. WebIn biology, a species complex is a group of closely related organisms that are so similar in appearance and other features that the boundaries between them are often unclear.

WebAllopatric speciation is just a fancy name for speciation by geographic isolation, discussed earlier. In this mode of speciation, something extrinsic to the organisms prevents two or more groups from mating with each other regularly, eventually causing that lineage to speciate.
