Geographic Isolation is one of the most important factors.

Answer 2

Speciation is a process of diversity in species appears with time and the most important factor that plays a huge role in speciation is "geographical isolation".

Geographic isolation is a term that is used to explain isolation among species due to their mating pattern with other organisms of the same species. Migration of species from one place to another place due to several external factors such as temperature and food scarcity, also leads to change in their mating pattern that results in speciation.
