Divergence
Actually it is.
Sympatric Speciation develops within the range of the parent population. This type of speciation does not include geographical isolation, and can occur rapidly if a genetic change results in a barrier between the mutants and the parent population.
Speciation can occur through various mechanisms, including allopatric speciation, where populations become geographically isolated and evolve independently, and sympatric speciation, where new species arise within the same geographic area, often due to behavioral or ecological differences. Other forms include parapatric speciation, where populations are adjacent but still diverge due to environmental gradients, and peripatric speciation, a form of allopatric speciation involving a small population at the edge of a larger one. These processes can be driven by factors such as natural selection, genetic drift, and reproductive isolation.
The two phases of speciation are allopatric speciation and sympatric speciation. Allopatric speciation occurs when populations are geographically isolated, leading to genetic divergence due to natural selection, mutation, and genetic drift. In contrast, sympatric speciation happens within the same geographic area, often through mechanisms such as polyploidy in plants or behavioral changes in animals that reduce gene flow. Both processes ultimately result in the formation of new species.
Both sympatric and allopatric speciation involve the formation of new species through the genetic isolation of populations. In both cases, reproductive barriers develop that prevent gene flow between populations, leading to divergence and eventually the formation of separate species. The key difference between the two is that sympatric speciation occurs within the same geographic area, while allopatric speciation involves speciation due to geographic isolation.
Allopatric speciation.
sympatric , allopatric and parapatric speciation

Isolation Is necessary for speciation to occur.
Actually it is.
if you are referring to the the worksheet the evolution of living things from the textbook holt science and technology, the answer is speciation
Alopatric speciation. " Other country. "
allopatric speciation
allopatric speciation
Caralous linnaeus theory is accepted theory of speciation
They both are mechanisms by which new species arise
This concept is called allopactric speciation.
