The process of speciation allows a single species to diverge into two. Dive into the different versions of this process, including “allopatric speciation” and “sympatric speciation,” and discover how ...

If one accepts some version of the biological species concept, the central problem of speciation is the origin of isolating barriers that prevent actual or potential gene flow among populations (Coyne ...

Theoretical studies indicate that while sympatric speciation is possible, the necessary conditions are considerably more stringent than for speciation in allopatry. Sympatric speciation encounters two ...

It has long been thought that dramatic changes in a landscape like the formation of the Andes Mountain range or the Amazon River is the main driver that initiates species to diverge. However, a recent ...

Contrary to what many people think, two species can hybridize naturally in the wild to give rise to a third species, a finding that fundamentally alters our understanding of the evolution of species ...

A team of researchers has provided the first example of how color patterns on a coral reef fish species can drive its evolution into many distinct species. The researchers looked at feeding and mating ...

"A new species develops if a population which has become geographically isolated from its parental species acquires during this period of isolation characters which promote or guarantee reproductive ...
