Allopatric speciation and sympatric speciation are two factors. Allopatric speciation occurs when physical barriers are formed, separating the specie. This will cause the specie to evolve at different rates causing a new specie to form. Sympatric speciation is less likely to occur when comparing it to allopatric. In sympatric speciation is no longer physical but generic. For example a mutation in the genetic order of the specie (which does not happen as often as physical barriers), and a different mating preference/season.
The theory you are referring to is called allopatric speciation. It suggests that new species can evolve when a population becomes geographically isolated, leading to genetic divergence and eventually the formation of distinct species.
This occurs through adaptive radiation and allopatric speciation. The reproductive isolation is the separation of two populations of the same species, preventing interbreeding and production of a fertile offspring.
Adaptive radiation is a rapid form of speciation that takes place when there is a mass immigration to new ecological niches, or a mass extinction of one dominant life form opening up niches for other life forms. Darwin's finches are examples of the former, as they reached the Galapagos Islands as one species and radiated from there into many different species of birds make there living in various ways that called for morphological changes, basically in beak size and shape. The death of the dinosaurs is an example of the latter radiation event. That is when several types of small mammals radiated out into all the niches left open bu the dinosaurs.
Kipukas are isolated areas of land spared by lava flows, providing opportunities for plant and animal species to evolve independently. Speciation in kipukas can occur through mechanisms such as genetic drift and adaptation to specific ecological niches within these unique habitats. Over time, these isolated populations may diverge and form new species due to the distinct environmental conditions present in kipukas.
The term that best describes the result of a new species evolving from an existing species is "speciation." This process occurs when populations of a species become reproductively isolated and undergo genetic changes over time, leading to the emergence of distinct species. Speciation can occur through various mechanisms, including allopatric, sympatric, and parapatric speciation.

Speciation
The theory you are referring to is called allopatric speciation. It suggests that new species can evolve when a population becomes geographically isolated, leading to genetic divergence and eventually the formation of distinct species.
The general term for the process by which new species form is "speciation." Speciation occurs when populations of a species become isolated and diverge through various mechanisms, leading to genetic and phenotypic differences that eventually result in the formation of distinct species.
The process by which new species form is called speciation. Speciation occurs when populations of a species become reproductively isolated and diverge over time, leading to the evolution of distinct species. This can happen through mechanisms such as geographic isolation, genetic drift, and natural selection.
Macroevolutionary processes ARE speciation. The allelic change over time is great enough to form a new species by the species concept; the species can no longer interbreed successfully.
B. Allopactric speciation on island archipelagos. As the organisms move from island to island rapid speciation is observed because of variations in resource acquisition more than just variation in environment. Amplified radiation is observed. Example is finches on the Galapagos Islands. Hawaii also gives this example.
Alopatric speciation.
