Researchers reported that octopuses are the first known invertebrates to show an increase over evolutionary time in microRNAs, which are gene-regulating molecules linked to the development of advanced cells and cognition in humans, mammals and other vertebrates. When combined with the known intelligence of octopuses, the findings provide crucial support for the theory that microRNAs are key to the evolution of intelligent life.
