Experts say octopuses could rule the world after we're gone.
Could octopuses become Earth's next dominant species after humans?
Some scientists think it's possible.
With intelligence rivaling that of mammals, tool use, problem-solving abilities, and highly sensitive perception, octopuses already possess many traits we associate with advanced species.
Their decentralized nervous systems-more akin to massive data processors than traditional brains-grant them remarkable dexterity and independence across their eight limbs. Biologist Tim Coulson believes these sea creatures might adapt and radiate across diverse environments in a post-human world, especially if they harness energy sources like tidal power.
But big hurdles remain before octopuses could build anything resembling civilization. Most species are solitary and cannibalistic, lacking the intergenerational learning and social structures necessary for cultural evolution. Scientists argue they would need to become more communal and parental to truly thrive as a society. Still, glimpses of social behavior in some species hint at potential. If octopuses don't rise to dominance, researchers say other unlikely creatures-like nematodes or even cockatoos-might take up the mantle. Either way, nature seems poised to continue, even in humanity's absence.
