ANN ARBOR--A new University of Michigan study of interbreeding between two species of howler monkeys in Mexico is yielding insights into the forces that drive the evolution of new species. How do new ...

Speciation is the process by which new species forms and is the driving force of biodiversity. Since Darwin published On the Origin of Species, great efforts have been performed without interruption ...

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 ...

Reproductive isolation is a biological process that prevents gene flow between populations or species, thereby maintaining or promoting genetic divergence and speciation. It operates through ...

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 ...

Mayr was well known for his championship of the biological species concept and for asserting a predominant role for the geographic separation of populations in the diversification process that gives ...

The modes of speciation that are thought to have contributed most to the generation of biodiversity require population differentiation as the initial stage in the speciation process. Consequently, a ...

"A new species develops if a population which has become geographically isolated from its parental species acquires during this period of isolation characters which promote or guarantee reproductive ...

Speciation is important because it increases biodiversity. A new thesis examines the speciation process in multiple marine species where different populations of the same species might evolve into two ...

Hendry's team observed that male river sockeyes are slimmer than their lake counterparts (to better deal with the river's strong current), while the female river sockeye are larger than their beach ...
