  • The interaction between hybridisation and polyploidisation is thought to play an important role in eukaryote speciation. Here the authors sequence yeast crosses and show associations between hybridisation, genome instability, and genome duplication, suggesting these may have roles in the establishment of new hybrids.

  • Saccharomyces cerevisiaehas become an important model organism in the field of evolutionary genomics. Comparative genomic analysis of laboratory, wild and domesticated yeast populations is generating insights into how new species form and how populations adapt to their environments.

  • Hybridization across species can lead to offspring with reduced fertility. Here, the authors experimentally evolve yeast and show that whole-genome duplication during asexual reproduction can restore fertility in hybrids over a relatively short evolutionary timespan.

  • Hybrids are often considered evolutionary dead ends because they do not generate viable offspring. Here, the authors show that sterile yeast hybrids generate genetic diversity through meiotic-like recombination by aborting meiosis and return to asexual growth.
