How ecological divergence can maintain strong reproductive isolation between populations in geographic contact remains poorly understood at the genomic level, but is here studied in a stickleback popu
Many bacterial lineages lack seemingly essential metabolic genes. Previous work suggested selective benefits could drive the loss of biosynthetic functions from bacterial genomes when the correspondin
Atlantic killifish populations have rapidly adapted to normally lethal levels of pollution in four urban estuaries. Through analysis of 384 whole killifish genome sequences and comparative transcripto
