LOGAN, UTAH, USA - At what point on the journey along the branches of the evolutionary tree does a population become its own, unique species? And is a species still distinct, if it mates with a ...

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 ...

A new approach to genomic species delineation could impact policy and lend clarity to legislation for designating a species as endangered or at risk. Evolutionary biologists model the process of ...

Speciation is important because it increases biodiversity. A thesis from the University of Gothenburg examines the speciation process in multiple marine species where different populations of the same ...

What is ecological speciation? -- Predictions and tests of ecological speciation -- A source of divergent selection -- A form of reproductive isolation -- A genetic mechanism to link selection to ...

Reinforcement, the increase of assortative mating driven by selection against unfit hybrids, is conditional on pre-existing divergence. Yet, for ecological divergence to precede the evolution of ...
