Ability To Rewrite Their Own RNA May Be Behind Octopus Intelligence

Octopuses are alien life among us. They are able to use tools, have three hearts, their arms contain 2/3 of the neurons in an octopuses body and almost have minds of their own, their blood is based on copper rather than iron, and is blue, and are thought to be the most intelligent invertebrates and an important example of advanced cognitive evolution in animals. They also have a special way of using their genes. [Read More]

Octopus Secrets Revealed By Alien Genome

Dramatic differences between the octopus and other invertebrates have been discovered by scientists. The first whole genome analysis of an octopus also shows significant genomic rearrangements, as well as a striking expansion of a family of genes involved in neuronal development once thought to be unique to vertebrates. As reported in Nature, the team uncovered genomic features that likely played a role in the evolution of traits such as large complex nervous systems and adaptive camouflage, including hundreds of octopus-specific genes.
