ADVANTAGES OF SPECIES BARRIERS? Natural selection can increase reproductive isolation (the Wallace Effect). Allopatric selection from adaptive divergence also leads to an increase in speciation. The production of viable offspring is the key driver in nature. Differences in molecular construction and compatibility can lead to sterility or in viable offspring. Perhaps it is all just an accident of molecular incompatibility, just like sexual organ incompatibility can cause a barrier, rather than a competitive advantage.
