Arecently published phylogeny of Hawaiian cricket species adds to the ongoing debate about the importance of sexual selection in speciation. The phylogeny implies that the genus has speciated faster ...

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 ...

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 ...

March 2 (UPI) --Friendship may be forever, but species diversification isn't. New research suggests speciation is a two-way street. In a new study, scientists offer evidence of two distinct common ...

A University of Arizona graduate student may be the first eyewitness to the birth of a new species. Her new findings, appearing in the June 7, 2004 Proceedings of the National Academy of Science, ...

"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 ...

For over a century, speciation -- where one species splits into two -- has been a central focus of evolutionary research. But a new study almost 20 years in the making suggests "speciation reversal" - ...

As an animal evolves, it can sometimes fork into two separate species. Also known as speciation, this phenomenon depends significantly on the animal’s natural living environment and has repeatedly ...

The Midas cichlid fish from the crater lakes of Nicaragua are one of the the best known examples for sympatric speciation. They evolved from a source population into a variety of independent species ...

Just offshore from the pebble beaches of Bere Point on Malcolm Island, British Columbia, the Naiad Explorer rocks gently in the waters of the Queen Charlotte Strait. The sun has burned off most of the ...

A new study almost 20 years in the making provides some of the strongest evidence yet of the 'speciation reversal' phenomenon -- where two distinct lineages hybridize and eventually merge into one -- ...
