Sympatric speciation

Sympatric speciation (reproductive isolation)
Genetic isolation by mutation / reproductively isolated / but inhibit same habitat
Drift can cause further divergence between isolated gene pools
Hybridisation in plants ...

Sympatric Speciation
Sympatric speciation happens when members of a population develop some genetic difference that prevents them from reproducing with the parent type.

Sympatric Speciation
Sympatric speciation refers to the formation of two or more descendant species from a single ancestral species all occupying the same geographic location.

sympatric speciation
[Gk. syn, together with + patra, fatherland, country]
A mode of speciation occurring as a result of a radical change in the genome that produces a reproductively isolated subpopulation in the midst of its parent population.

5 Sympatric Speciation in Drosophila melanogaster
In a series of papers (Rice 1985, Rice and Salt 1988 and Rice and Salt 1990) Rice and Salt presented experimental evidence for the possibility of sympatric speciation.

sympatric speciation Speciation that occurs in populations that have overlapping ranges.
sympatry Populations or species with overlapping geographic distributions. Contrast with allopatry.

In sympatric speciation, species diverge while inhabiting the same place. Examples of sympatric speciation are found in insects which become dependent on different host plants in the same area.

Sympatric speciation: the formation of new species without geographic isolation; the acquisition of reproductively isolating mechanism among individuals coexisting in the same area. Not infrequent in plants.
