Sympatric speciation is among the most controversial and challenging concepts in evolution.
There are a multitude of definitions of speciation alone, and when combined with the …

Sympatric speciation has always fascinated evolutionary biologists, and for good reason; it
pits diversifying selection directly against the tendency of sexual reproduction to …

Until recently, our view of speciation was that reproductive isolation evolves during long
periods of allopatry through the accumulation of genetic differences that result in genetic …

The likelihood of sympatric speciation is perhaps the most controversial aspect of speciation,
and certainly one of the most contested questions in evolutionary biology. Speciation in …

Sympatric speciation, the evolution of reproductive isolation without geographic barriers,
remains highly contentious. As a result of new empirical examples and theory, it is now …

Sympatric speciation has been of key interest to biologists investigating how natural and
sexual selection drive speciation without the confounding variable of geographic isolation …

Sympatric speciation has become increasingly accepted in the past decade, as a result of
new models substantiating its plausibility and new evidence that the conditions specified by …

Sympatric speciation illustrates how natural and sexual selection may create new species in
isolation without geographic barriers. However, recent genomic reanalyses of classic …

While it now appears likely that sympatric speciation is possible, its generality remains
contentious. If it really is rare, then most natural populations must not fit the assumptions of …

Sympatric speciation is a composite phenomenon requiring both ecological differentiation
and the evolution of a mating structure that induces reproductive isolation. Ecological and …
