How do new species form? Like most areas of Evolutionary Biology, research related to the formation of new species - 'speciation ' - is rich in historical and current debate. Here, we review both ...

"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 ...

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 ...

Or is so-called sympatric speciation also possible -- the evolutionary divergence of a population within the same geographical area? Only few examples of sympatric speciation are known worldwide, and ...

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" - ...

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 ...

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 ...

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 -- ...
