The phenomenon of the sympatric speciation is a term that is used for the biological explanation for the evolution of new species which have been evolving to survive from the species formation which were formed from their ancestors. The word sympatric speciation has its roots in the Greek Language that translates to ‘homeland together’. The term was first coined by Edward Bagnall Pultron, in the year 1904 that completely explains the theory behind the sympatric speciation and the derivation of the term. The species have been evolving from their ancestral forms to the genetically modified form only to strive with the changes in the environment but being in the same geographical region. When the term sympatric speciation is explained with the help of the concepts of biogeography and evolutionary biology, it is specified that there are two forms of the referred organisms about this concept that specify the sympatric and sympatry are two different types of the terms that are used for different organisms. These organisms are the ones that ranges from the overlapping nature they possess for occurring together in the same place. When both the organisms are found to be on the closely related species, they are termed as the sister species and they appear to be belonging to the distribution of the species that would automatically relate to the sympatric speciation. This is the biological term that describes the genetic modification of the species and usually handled with the help of the geographical location of the species.

The phenomenon of sympatric speciation occurs when the specific population of a species are belonging to the same geographical location or the same habitat. The occurrence of the speciation is mostly dependent on the phenomenon that is dependent on the occurrence of polyploidy in the species which is a biological phenomenon that occurs between the offspring of the species with the generation of the number of the general chromosomes that are doubled in nature. Speaking it in a much simpler format, it can be said that the species are split into two groups with the processing of future generations such that the two species belonging to the offspring zone do not share the similar genetic pools as it would have occurred before. Therefore, this phenomenon holds special importance in the provision of the understanding that is related to the studies of the evolution of the same species ranging from different locations or belonging to the same location. The idea behind the phenomenon of sympatric speciation especially makes it easier to understand how is it possible that organisms belonging to the same species and belonging to the same geographical location do not share the similar genetic coding. For example, the Hawthorn Fly is also considered to be a species generating the characteristics of sympatric speciation. However, this is based on the preference that the species usually inhabit based on the location they chose for laying their eggs. The idea is to find out the genetic evolution of different species as it appears on the same geographical area.
