Speciation - Wikipedia, the free encyclopedia

Speciation is the evolutionary process by which new biological species arise. The biologist Orator F. Cook seems to have been the first to coin the term 'speciation' for the splitting of lineages or ...

Unlike the previous modes, sympatric speciation does not require large-scale geographic distance to reduce gene flow between parts of a population. How could a randomly mating population reduce gene flow and speciate?

The key to speciation is the evolution of genetic differences between the incipient species. For a lineage to split once and for all, the two incipient species must have genetic differences that are expressed in some way that causes matings between them to either not happen or to ...

There has been much debate about whether speciation can occur without a population being physically split by some barrier. This type of speciation is called sympatric speciation. Sympatric speciation has probably been responsible for producing the great diversity of cichlid fish in some African lakes.

Evolutionary Biology: Evidence for sympatric speciation? ... Sympatric speciation is difficult to demonstrate in nature and remains a hotly debated issue. Barluenga et al.1 present a case of putative sympatric speciation for two cichlid species in the Nicaraguan crater lake Apoyo, but they overlook or reinterpret some...
