Detailed explanation-1: -Speciation occurs when a group within a species separates from other members of its species and develops its own unique characteristics. The demands of a different environment or the characteristics of the members of the new group will differentiate the new species from their ancestors.
Detailed explanation-2: -Speciation is the process by which new species form. It occurs when groups in a species become reproductively isolated and diverge. In allopatric speciation, groups from an ancestral population evolve into separate species due to a period of geographical separation.
Detailed explanation-3: -In the most common type of speciation, allopatric speciation, new species arise via the geographic isolation of populations (Figure 6.1).
