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 ...

The diversification of a lineage is the net output of speciation minus extinction. A theme that runs through much research into human evolution is whether the determinants of hominin diversification ...

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"—where ...

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 ...

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 ...

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 could help biologists identify and understand the precise genetic changes that lead ...

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 -- ...

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 ...
