Butterfly genomics sheds light on the process of hybrid speciation.
How common is hybridization between species and what effect does it have on the evolutionary process? Can hybridization generate new species and what indeed is a species? In this issue, Gompert et al. (2014) show how massive, genome-scale data sets can be used to shed light on these questions. They focus on the Lycaeides butterflies, and in particular, several populations from the western USA, ...
متن کاملMicrobial Speciation.
What are species? How do they arise? These questions are not easy to answer and have been particularly controversial in microbiology. Yet, for those microbiologists studying environmental questions or dealing with clinical issues, the ability to name and recognize species, widely considered the fundamental units of ecology, can be practically useful. On a more fundamental level, the speciation ...

متن کاملPlant speciation.
Like the formation of animal species, plant speciation is characterized by the evolution of barriers to genetic exchange between previously interbreeding populations. Prezygotic barriers, which impede mating or fertilization between species, typically contribute more to total reproductive isolation in plants than do postzygotic barriers, in which hybrid offspring are selected against. Adaptive ...
متن کاملSympatric speciation
What is sympatric speciation? The likelihood of sympatric speciation is perhaps the most controversial aspect of speciation, and certainly one of the most contested questions in evolutionary biology. Speciation in general is defined as the evolution of strong, genetically based ‘isolating barriers’ between populations that prevent them from exchanging genes, for example, mate discrimination, ha...
