Sympatric speciation is the process in which two groups of organisms living in the same habitat diverge into separate species.
The evolution of a new species from a surviving ancestral species while both remain in the same geographic region is known as sympatric speciation. In evolutionary biology and biogeography, sympatric and sympatry refer to organisms whose ranges overlap to the point where they coexist at least in some places. If these organisms are closely related (for example, sister species), this distribution could be due to sympatric speciation. Sympatry is derived from the Greek roots v ("together") and t ("togetherness") ("homeland"). Edward Bagnall Poulton coined the term in 1904.
