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 ...

It has long been thought that dramatic changes in a landscape like the formation of the Andes Mountain range or the Amazon River is the main driver that initiates species to diverge. However, a recent ...

Corrales, a recent biological sciences Ph.D. graduate from the University of Rhode Island, and his advisor, Associate ...

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 ...

Studies of reproductive isolation have shown that the number of genes that are involved is often large. Between closely related species of Drosophila, the number of such genes might often be in the ...

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 ...

After up to two million years of separate evolution, two types of common raven have been ‘caught in the act’ of consolidation, say scientists Speciation, where one species diverges into two, is a well ...

Together, these results indicate that the single genetic swap probably set speciation in motion, Uy said. "I think we do have a speciation gene because this substitution creates a different physical ...

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" - ...

German researcher Christian Rabeling was digging up ant colonies on a college campus in Brazil when he found something unexpected—certain ants appeared smaller and shinier and had wings. Rabeling soon ...

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 -- ...
