Speciation, the formation of new and distinct species in the course of evolution. Speciation involves the splitting of a single evolutionary lineage into two or more genetically independent lineages.
Sympatric speciation is when two species (in the same geographic area) evolve from the same ancestor organism. As for an example, try doing a search for sympatric speciation stickleback.That should give you a great deal of information on speciation.Cheers!n Sympatric Speciation the separation is non-geographical but more behavioural or social. This form of speciation is believed to be particularly significant in the evolution of insect species and is subsequently favoured as a route of speciation by Entymologists.
