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 ...

Speciation is one of the core issues in evolutionary biology. Sympatric speciation is the evolution of reproductive isolation without geographic barriers in which new species arise from a single ...

Or is so-called sympatric speciation also possible -- the evolutionary divergence of a population within the same geographical area? Only few examples of sympatric speciation are known worldwide, and ...

Mate choice, competition, and the variety of resources available are the key factors influencing how a species evolves into separate species, according to a new mathematical model that integrates all ...

One of the world's best examples of sympatric speciation, when two species from a single ancestor form in the absence of a geographical barrier, has been found among the swaying palm trees on ...

The Midas cichlid fish from the crater lakes of Nicaragua are one of the the best known examples for sympatric speciation. They evolved from a source population into a variety of independent species ...

The mechanisms by which new species arise are still not fully understood. What are the evolutionary processes that drive the evolution of new species? Evolutionary biologists traditionally assumed ...

Reproductive isolation between groups of individuals would appear to be a sine qua non for the evolution of new species, without which gene flow between those individuals would maintain genetic ...

"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 ...
