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 ...

Speciation is a concept in evolutionary process wherein new and distinct species are formed. A new research discovered the reversal of speciation in ravens. The study, which is the product of an ...

Continental lake-dwelling zooplanktonic organisms have long been considered cosmopolitan species with little geographic variation in spite of the isolation of their habitats. Evidence of morphological ...

Clues from fish diversity suggest that interbreeding between species could be a major mechanism of fast speciation. To biologists eager to understand how one species can split into two, the apple ...

The evolution of a new species can occur rapidly enough for them to observe the process in a simple laboratory flask, biologists have discovered. In a month-long experiment using a virus harmless to ...

Scientists have theorized that how fast one species branches out to become two, a process called speciation, is in the genes. If a couple of key genes are located close to each other on the 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 ...

The tunnels of the London Underground are hot, dark, and damp. Crowds of warm-blooded humans congregate on the platforms. Stagnant pools of water collect beneath the tracks. The subterranean transit ...

Within-species variance in corticosterone levels showed close to zero repeatability, thus it is highly unlikely that this is a species-specific trait that influences diversification rates. These ...

A paper published by URI researchers reveals key mechanisms in speciation in corals. Critically threatened by climate change, a better understanding of coral biology will help efforts to conserve and ...
