the continent moved creating a new environment because of water and air temperature. Therefor species had to change.
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.
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.
In allopatric speciation, geographic isolation occurs first when a population becomes physically separated by barriers such as mountains, rivers, or distance. This separation prevents individuals from interbreeding, leading to reproductive isolation over time as the two populations evolve independently. As genetic divergence increases due to natural selection, mutation, and genetic drift, reproductive isolation mechanisms develop, resulting in the emergence of distinct species.
Geographic isolation does not need to be maintained indefinitely for speciation to occur because the initial separation can lead to divergent evolutionary paths due to different selective pressures and genetic drift. Over time, even if populations come back into contact, they may have accumulated sufficient genetic differences and adaptations that prevent interbreeding, thus maintaining reproductive isolation. This process can result in the emergence of distinct species even after the original geographic barriers are removed.
Speciation caused by geographic division is known as allopatric speciation. This process occurs when a population is separated by physical barriers, such as mountains or rivers, leading to reproductive isolation. Over time, the isolated groups may evolve distinct traits and become separate species due to differing environmental pressures and genetic drift.

Geographic isolation as a mechanism for reproductive isolation. In sympatric speciation, new species arise within the same geographic area without physical barriers separating populations. This process typically involves ecological, behavioral, or genetic factors leading to reproductive isolation within a single population.
That would be geographic isolation and reproductive isolation. Both could lead to speciation.

Geographic isolation causes the environments to separate. The members of each side will be separated and gradually become more and more distinct as time goes. Eventually, when they are unable to interbreed, that is evidence of speciation.
Specation can be used in many ways.
