At the center of the new findings is an evolutionary concept called sympatric speciation, the possibility “for a species to split into two species without any geographic separation,” Schultz says.

Yet, even under ideal conditions, sympatric speciation occurred only a fraction of the time in the model. But that does not mean sympatric speciation is not impossible in nature, the authors argue.

Thus, two new examples of sympatric speciation that are recently described in Nature (Barluenga et al, 2006; Savolainen et al, 2006) form an important expansion of the literature.

Heredity - Speciation: Reinforced butterfly speciation. ... This provides further support for the plausibility of sympatric speciation and suggests that it may be more common than is often supposed.

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 ...

Study: Cooperation, not struggle for survival, drives speciation, evolution "Evidence for sympatric speciation is growing," said researcher David Marques. By Brooks Hays.

But a number of recent theoretical studies have suggested that so-called sympatric speciation can occur, in which different populations originate in one geographical area, but do not interbreed.
