3D genome 'entanglement' may explain cephalopods' complex brains

Original: 3D genome 'entanglement' may explain how cephalopods evolved complex brains

Researchers report that 3D genome 'entanglement' may explain how cephalopods, including octopuses and squid, evolved their remarkably complex brains. The finding suggests the way DNA folds and interacts within cells could have allowed large-scale genetic rearrangements, driving the development of sophisticated neural systems unique among invertebrates.

Why now: New research into the genetic origins of cephalopod intelligence is drawing attention to how genome structure shapes brain evolution.
