The theory was originally developed as island biogeography, to explain species richness of actual islands, principally oceanic. It proposes that the number of species found in an undisturbed insular environment is determined by immigration and extinction.
Explanation:
Wilson of Harvard, developed a theory of "island biogeography" to describe such uneven distributions. They suggested that the number of species on any island displays a balance within the rate at which new species establish it and the rate at which residents of secured species become extinct.
