How do new species arise? Speciation is difficult to observe directly because it is a long, slow process in nature. It has been theorized that when populations of a species separate and adapt to different environments they become less successful at interbreeding and may form new species. An experimental test, involving two yeast strains evolving under laboratory conditions that accelerated speciation, confirms that hybrids of populations adapted to different environments were less able to reproduce (less fit) than hybrids of populations all adapted to the same environment. This is evidence for a fundamental link between divergent adaptation and the development of reproductive isolation......
