How can sympatric speciation occur
WebSympatric speciation is the evolution of a new species from a surviving ancestral species while both continue to inhabit the same geographic region.

Four main types of population pairs exist in nature. Sympatric populations (or species) contrast with parapatric populations, which contact one another in adjacent but not shared ranges and do not interbreed; peripatric species, which are separated only by areas in which neither organism occurs; and allopatric species, which occur in entirely distinct ranges that are neither adjacent nor overlapping.
