Sympatric


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

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

Sympatric
Occurring in the same place.
Synapomorphy
Shared derived characters that are regarded as homologous are called synapomorphies, e.g. the presence of mammary glands in all three lineages of mammals (monotremes, marsupials and placentals).

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.

sympatric Having the same or overlapping regions of geographical distribution. Noun, sympatry.
sympatric speciation Speciation that occurs in populations that have overlapping ranges.

Sympatric speciation occurs when two subpopulations become reproductively isolated without first becoming geographically isolated. Insects that live on a single host plant provide a model for sympatric speciation.
Full article >>>

In sympatric speciation, species diverge while inhabiting the same place (sympatric). Examples of sympatric speciation are found in insects which become dependent on different host plants in the same area. Increased ploidy levels, i.e.

The proposed species are sympatric—they occupy the same habitat. Observation of many species over the years has failed to establish even a single instance of two diagnostically different populations that exist in sympatry and have then merged ...

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.
