Geographic isolation can affect mating probabilities between two separated populations, but it does not always result in reproductive isolation or the formation of new species. It is also not required for speciation, as there are other factors that can contribute to the emergence of new species, such as polyploidy or adaptive radiation. Finally, the effects of geographic isolation may vary depending on the specific characteristics and adaptations of the organisms involved.
