Why Are Octopuses So Smart? The Answer May Lie in How Their DNA Folds

The extraordinary intelligence of octopuses, squid, and cuttlefish may be linked to more than just their genes. Octopuses can solve problems, squid can rapidly change their appearance, and cuttlefish display remarkably sophisticated behaviors. These abilities rely on unusually complex nervous systems, but how such biological complexity evolved remains an open question. A new study suggests [...]
