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 ...

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 ...

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 ...

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 ...

New species can form astonishingly quickly — or the process can take eons. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Charles Darwin ...

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 ...

It’s a tale as old as wine. Two organisms meet over a barrel of alcohol and decide to mate. Geneticist Maitreya Dunham didn’t see it happen. But she has molecular evidence that two yeast species ...
