What can cause speciation?

In this way, what are the four types of speciation?
There are four major variants of speciation: allopatric, peripatric, parapatric, and sympatric. Speciation is how a new kind of plant or animal species is created. Speciation occurs when a group within a species separates from other members of its species and develops its own unique characteristics.
Secondly, what causes speciation quizlet? When populations of the same species become genetically isolated by lack of gene flow and then diverge from each other due to selection, genetic drift, or mutation.
Regarding this, what must happen for speciation to occur?
New species arise through a process called speciation. For speciation to occur, two new populations must be formed from one original population, and they must evolve in such a way that it becomes impossible for individuals from the two new populations to interbreed.
What type of natural selection causes speciation?
In many cases of speciation by divergent selection, enough ecologically based reproductive isolation will evolve to isolate a pair of new species before many DMIs can accumulate.
