All these predictions have now ... A lack of strong examples for speciation by genetic drift, yet evidence for ecologically-similar species pairs (Price 2007), has led to the development of ...

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 ...

Speciation is the process by which a single species gives rise to two daughter species, which are genetically distinct and eventually unable to interbreed. Speciation can occur as a result of ...

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 ...

All of them evolved from one ancestral species, which colonized the islands ... Indeed, the Galapagos have been called a living laboratory where speciation can be seen at work.
