Detailed explanation-1: -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 is an evolutionary process by which a new species comes into being. A species is a group of organisms that can reproduce with one another to produce fertile offspring and is reproductively isolated from other organisms.
Detailed explanation-3: -It is an evolutionary process that leads to the formation of a new and distinct species that is reproductively isolated from another species. Speciation is also called ‘cladogenesis’, which means arising from a splitting event where the parent is split into two distinct species.
Detailed explanation-4: -Natural selection has always been considered a key component of adaptive divergence and speciation (2, 15–17), but the importance of selection has been eclipsed in recent decades by a strong focus on the geography of speciation and on the purely genetic mechanisms by which reproductive isolation evolves (see refs.
Detailed explanation-5: -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.
