The idea that one species give rise to new kinds of species, new genera, new families, orders, classes, or kingdoms is known as Speciation.
Step-by-step explanation:
Speciation is an evolutionary process in which new and different species are formed. In this process the new species is produced with the chromosomes twice the normal number. Speciation generally happens when the members in the large population leave the group and migrate to different location.
There are four types of speciation,
i) Allopatric Speciation
ii) Sympatric Speciation
iii) Parapatric Speciation
iv) Quantum Speciation
Geographical isolation, genetic drift and natural selection are the main cause of speciation.
