3D DNA structure may explain cephalopods' complex brains
Original: 3D structure of DNA may explain how cephalopods evolved complex brains
A new study suggests the three-dimensional organisation of DNA may explain how cephalopods—octopuses, squids and cuttlefish—evolved their unusually complex brains. Researchers point to changes in genome architecture as a driver behind the expansion of neural complexity in these molluscs, a case of sophisticated cognition evolving independently of vertebrates.
Why now: New research offers a fresh explanation for one of evolution's most striking examples of independent intelligence.
