Detailed explanation-1: -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.

Detailed explanation-2: -Speciation can be natural and can occur as a normal part of the evolutionary process. Artificial speciation is also possible and can be created by laboratory experiments or through agriculture and animal husbandry. Fruit flies are a primary example of artificial speciation. Another well-known example is domestic sheep.

Detailed explanation-3: -Sympatric speciation is rare. It occurs more often among plants than animals, since it is so much easier for plants to self-fertilize than it is for animals.
