What is it called when speciation occurs even though populations live within the same geographical area. When a population disperses throughout an area, into new, different and often isolated habitats, multiple speciation events can occur in which the single original species gives rise to many new species; this phenomenon is called adaptive radiation. Convergent evolution occurs in an unrelated group of organisms. When this involves large number of species to occupy different ritches, this is called the adaptive radiation.
