How does speciation occur through isolation
WebFeb 12, 2024 · Like all forms of speciation, the process is usually very gradual. Parapatric speciation is when speciation occurs in subpopulations of the same species that are mostly isolated from each other, but have a narrow area where their ranges overlap. WebAllopatric speciation involves geographical isolation of a population from other populations of the parental species, and acquisition of characters that promote or ensure reproductive isolation once sympatry is reestablished. A plausible scenario for …
