"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 a central and fundamental process in evolution that concerns the origin of reproductive isolation. The latest generation of genomic approaches provide remarkable opportunities to ...

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

When two organisms typically do not interbreed with one another, they are considered different species. But what are the reproductive barriers that isolate one population from another? Hear the ...

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 ...

Matías Gómez-Corrales, a recent biological sciences Ph.D. graduate from the University of Rhode Island, and his advisor, Associate Professor Carlos Prada, have published a paper in Nature ...

This process, called "reinforcement", prevents closely related species from interbreeding thus driving them further apart genetically and promoting speciation. Although scientists have speculated ...

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 ...
