3D genome 'entanglement' may explain how cephalopods evolved complex brains
Scientists at the University of Vienna found that the 3D organization of the genome may have contributed to the evolution of complex brains in cephalopods, such as octopuses, squid, and cuttlefish. 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 matters
Cephalopods have exceptionally large and complex nervous systems, but the origins of this complexity are not well understood. The study's findings provide insights into how genomic changes can translate into organismal novelties. Understanding this process could change how we think about the emergence of new traits during evolution.
