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, the formation of new and distinct species in the course of evolution. Speciation involves the splitting of a single evolutionary lineage into two or more genetically independent lineages.
Detailed explanation-3: -Speciation is an evolutionary process by which a new species comes into being.
Detailed explanation-4: -Adaptive radiation is the process by which one species evolves into two or more species. This occurs as a result of different populations becoming reproductively isolated from each other, usually by adapting to different environments.
Detailed explanation-5: -The two modes of speciation are allopatric speciation and sympatric speciation. During allopatric speciation one population is divided by a geographical barrier. In sympatric speciation one population is divided into different groups based on behavioral changes rather than geographic isolation.
