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 ...

If one accepts some version of the biological species concept, the central problem of speciation is the origin of isolating barriers that prevent actual or potential gene flow among populations (Coyne ...

Extra genomes appear, on average, to offer no benefit or disadvantage to plants, but still play a key role in the origin of new species, say scientists. Plant biologists have long suspected polyploidy ...
