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 ...

"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 ...

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 ...

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

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 ...

The spectacular radiation of 2,000 species of cichlid fishes in East Africa is an ideal model system and natural laboratory for studying evolutionary processes. The explosive speciation of cichlids is ...

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 -- ...
