When two organisms typically do not interbreed with one another, they are considered different species. But what are the reproductive barriers that isolate one population from another? Hear the ...

In natural populations, the mechanisms of evolution do not act in isolation. This is crucially important to conservation geneticists, who grapple with the implications of these evolutionary processes ...

1. The Crinia signifera and C. insignifera superspecies include seven closely related species which, while lacking much morphological variation, show marked differentiation in male mating-call ...

Experiments were designed to clarify the role of olfactory stimuli in sexual isolation between the closely related and allopatric mice, Peromyscus maniculatus rufinus and P. polionotus leucocephalus.

The budding yeast Saccharomyces cerevisiae has become an important model for evolutionary genomics owing to the development of high-throughput sequencing technologies. Comparative genomics analysis of ...
