The process of speciation allows a single species to diverge into two. Dive into the different versions of this process, including “allopatric speciation” and “sympatric speciation,” and discover how ...

If one accepts some version of the biological species concept, the central problem of speciation is the origin of isolating barriers that prevent actual or potential gene flow among populations (Coyne ...

Studies of reproductive isolation have shown that the number of genes that are involved is often large. Between closely related species of Drosophila, the number of such genes might often be in the ...

It has long been thought that dramatic changes in a landscape like the formation of the Andes Mountain range or the Amazon River is the main driver that initiates species to diverge. However, a recent ...

A team of researchers has provided the first example of how color patterns on a coral reef fish species can drive its evolution into many distinct species. The researchers looked at feeding and mating ...

Blind mole rats could be a real eye-opener for evolutionary science. According to a new study, the burrowing rodents are key to answering a controversial question about how new species arise. Sex is a ...
