How do new species form ... Sympatric, parapatric or allopatric: The most important way to classify speciation? Philosophical Transactions of the Royal Society B: Biological Sciences 363, 2997 ...

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 ...

Vicariance is the emergence of geographic barriers to dispersal and gene flow, which spatially isolates populations and may lead to the formation of new species (i.e., allopatric speciation ...

Having at least briefly considered the problems of phylogenetics and systematics using genetic markers, we will turn to speciation. This is one of the fundamental problems of evolutionary biology -- ...

But the origin of a species, otherwise known as speciation, takes thousands, maybe millions of years, a fact that makes it extraordinarily difficult to study. Consequently, the process of speciation ...
