WebExplanation: Biogeographical isolation is a speciation process that involves the evolution of the species due to the forces like physical and biological that result in to new species. This type of evolution result in a new species that are not reproductive fertile or compatible with the species from they isolated. WebGeographic isolation refers to the separation of members of a population by a physical barrier, such as a mountain or body of water, which disrupts the gene flow between them and begins the process of speciation. …
