Scientists find a surprising genetic twist behind octopus intelligencehttps://www.sciencedaily.com/releases/2026/10/261011211552.htm
The remarkable intelligence of octopuses, squid, and cuttlefish may trace back to an ancient reshuffling of their DNA that created new connections between genes. Scientists discovered that these changes in the genome's 3D structure may have helped drive the evolution of their unusually complex nervous systems.
