Question

Discuss the mechanisms of speciation

Answer 1

The key to one species diverging into two or more different species is establishing a barrier to gene flow. ... In this way, geographic isolation may lead to reproductive isolation and the formation of new species. Allopatric speciation is thought to be the main mechanism of speciation among most groups of organisms.

Answer 2

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.
