Solution
The process of speciation, if defined by reproductive isolation, is equivalent to "The evolution of reproductive isolating mechanisms". This is because reproductive isolation is a mechanism that prevents species from mating with others. This can evolve over time due to factors like geographical changes, behavioral changes, or genetic changes that result in physical incompatibilities. Therefore, the evolution of these mechanisms directly leads to speciation.
