The biological equivalent is "allopatric speciation," an evolutionary process in which one species divides into two because the original homogenous population has become separated and both groups ...

How do new species form? Like most areas of Evolutionary Biology, research related to the formation of new species - 'speciation ' - is rich in historical and current debate. Here, we review both ...

As long as the individuals in a population have the opportunity to interbreed and combine genes, they remain one species. A population of one species can only evolve into more than one species if ...

What is unknown is whether such local ‘adaptations' are correlated with genetic differentiation, which is a necessary precursor to speciation. Future studies that incorporate ecological ...
