The process of speciation allows a single species to diverge into two. Dive into the different versions of this process, including “allopatric speciation” and “sympatric speciation,” and discover how ...

Theoretical studies indicate that while sympatric speciation is possible, the necessary conditions are considerably more stringent than for speciation in allopatry. Sympatric speciation encounters two ...

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 ...

Identification of genes involved in reproductive isolation opens novel ways to investigate links between stages of the speciation process. Are the genes coding for ecological adaptations and sexual ...

Contrary to what many people think, two species can hybridize naturally in the wild to give rise to a third species, a finding that fundamentally alters our understanding of the evolution of species ...

(Phys.org)—A research team working in Israel has found what might possibly be an example of evolutionary divergence in action – and it's not due to a natural barrier. In their paper published in the ...

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 ...

"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 ...

This activity is designed to make the process of speciation more accessible to students by involving them in an example using the fictional species the Tub-Tubs. Throughout the process you can ...
