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: -The two key influencing factors on the change in speciation rate are the environmental conditions and the population size.
Detailed explanation-3: -Reproductive isolation is important for speciation. Reproductive isolation is a process in which two populations of a species are prevented from interbreeding among them. Therefore, this leads to the origin of new species which is called speciation.
