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 ...

I expect you to read: Avise, J.C. 2004. Chapter 7: Speciation and hybridization. In Molecular Markers, Natural History and Evolution (2nd edn.). Chapman and Hall, New York. Having at least briefly ...

Speciation is the process by which a single species gives rise to two daughter species, which are genetically distinct and eventually unable to interbreed. Speciation can occur as a result of ...

The more we discover about our species' family tree, the harder it becomes to pinpoint when exactly Homo sapiens emerged, ...

But according to a study published this week in Nature, new species can arise arbitrarily and without provocation, challenging the widely held notion that physical isolation and selection are the ...

As long as the individuals in a population have the opportunity to interbreed and combine genes, they remain one species. A population of one species can only evolve into more than one species if ...

The biological equivalent is "allopatric speciation," an evolutionary process in which one species divides into two because the original homogenous population has become separated and both groups ...

Learn about the evolutionary ease of cichlid fishes, which transition from simple to complex teeth (and vice-versa) faster ...

In project SpecIAnt we study speciation and hybridization using wood ants as a model system. We focus on the recently diverged Formica rufa group wood ants, many of which occur in Southern Finland ...

Indeed, the Galapagos have been called a living laboratory where speciation can be seen at work. A few million years ago, one species of finch migrated to the rocky Galapagos from the mainland of ...

Transforming an untamed wolf into an obedient sausage dog or clingy chihuahua requires some serious time and genetic alchemy, yet new research suggests the process may have been simpler than you'd ...
