An international team of researchers have sequenced the whole genome of an octopus, revealing unique genomic features that likely played a role in the evolution of traits such as large complex nervous systems and adaptive camouflage. They sequenced the genome of the California two-spot octopus, the first cephalopod ever to be fully sequenced, and mapped gene expression profiles in 12 different tissues. The study is published in Nature. Cephalopods are the most intelligent invertebrates and have demonstrated elaborate problem-solving and learning behaviors.
