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 paper appears in the Journal of Evolutionary Biology. New species more commonly ... A less common type of speciation, called "sympatric," occurs when a new species arises from a single ...

Before jumping into the specifics of speciation, it is beneficial to first understand the biological definition of a species. A species is a group of organisms whose members share similar traits, but ...

A 2015 study in the journal Molecular Biology and Evolution ... data from more than 50,000 species (though this included few bacteria), the researchers found that speciation generally requires ...

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 ...

But the origin of a species, otherwise known as speciation, takes thousands, maybe millions of years, a fact that makes it extraordinarily difficult to study. Consequently, the process of speciation ...

For over a century, speciation -- where one species splits into two -- has been ... professor of zoology and evolutionary biology at University of Oslo and another leader of the study.

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 ...

In a study published today in the journal Current Biology, Rabeling and ... evolutionary concept called sympatric speciation, the possibility “for a species to split into two species without ...

Arecent phylogeographical examination of east African river cichlid fish species has pinpointed the area of speciation to a now extinct lake in Botswana. The turbid rivers of Africa typically ...

This is evidence that ecological speciation can occur on short time scales and across species that are not necessarily known for being paragons of ecological speciation research in the past.

This unique bird raised an intriguing question: can hybrids give rise to a perfectly valid species? Hybrid speciation is quite rare in animals, but it does occur naturally. In this scenario ...
