Around 100 scientists gathered at Heidelberg recently for a workshop exploring the burgeoning use of yeasts in studies of evolution and ecology. Yeasts as model systems permit an ideal marriage between theory and experiment and the meeting concentrated on four core issues in evolutionary biology the architecture of the genome and its evolution the ecological and genetic structure of natural populations the mechanisms of selection that lead to adaptation and their study in the laboratory and the evolution of sex and mating systems. Here we report a few of the highlights. Genome structure and evolutionary process The genome sequences of many yeast species and strains are now available providing a playground for evolutionary biologists to pursue comparative genomics. Bernard Dujon Institut Pasteur Paris France presented the work of the Génolevures consortium on the genome evolution of hemiascomycetous yeasts focusing on the evolution of novel genes. The common ancestor of the Saccharomyces sensu stricto species complex Saccharomyces species that can mate to produce viable hybrids underwent a whole-genome duplication WGD around 100 million years ago and as Dujon described this event had a profound effect on the genome structure of the affected species and led to the emergence
