The researchers discovered that ancient genomic rearrangements brought distant DNA regions into contact, altering gene regulation. This process may have led to the development of large, elaborately structured nervous systems capable of complex behaviors like problem-solving and rapid camouflage.Why it mattersCephalopods have exceptionally large and complex nervous systems, but the origins of this co
