Answer :

A large portion of Earth's biological life variety may be attributed to speciation, which is the process by which one group of interbreeding populations or individuals divides into two or more reproductively separated groups. A new plant or animal species is developed through speciation. A group within a species undergoes speciation when it diverges from other individuals in the species and acquires its own distinct traits. speciation is the process of evolution in which new, different species are formed. A single evolutionary lineage is divided into two or more genetically distinct life during speciation.
