Answer 2

The situations that speciation will occur is ; when two populations are reproductively isolated. Speciation involves the formation of new and distinct species during evolution. It entails the splitting of a single evolutionary lineage into two or more genetically independent lineages. For example, in allopatric speciation, groups from an ancestral population evolve into separate species due to a period of geographical separation.
