Briefings

A University of Vienna study proposes that 3D genome organization, rather than just gene content, drives the evolution of complex nervous systems in coleoid cephalopods. The research suggests that how the genome is folded in three dimensions enables the rapid development of sophisticated behaviors like problem-solving and camouflage, potentially explaining the evolutionary leap from simpler to complex brains.

Key points

• Scientists at the University of Vienna propose that 3D genome organization, not just gene content, drives the evolution of complex nervous systems in coleoid cephalopods.
• The study indicates that the specific folding of the genome in three dimensions may enable rapid development of sophisticated behaviors such as problem-solving and camouflage.

Context and limitations

The study is a preprint from October 2026 and does not include peer review or full publication. Specific dates for behavioral observations or precise 3D structural measurements are not provided in the evidence.
