Who takes over if humans disappear from Earth? Scientists have a surprising answer
Produced by: Manoj Kumar
Octopus Takeover?
If humanity vanishes, octopuses may rule Earth. According to Oxford professor Tim Coulson, these intelligent marine creatures possess unique qualities that make them prime candidates for world domination.
Marine Masterminds
Tim Coulson told The European that octopuses are some of Earth’s most “resourceful creatures,” with problem-solving abilities and dexterous tentacles—a skill set that could help them construct civilizations in a post-human world.
Problem-Solving Pros
Octopuses exhibit advanced cognition, manipulating objects, using tools, and even solving puzzles. Coulson notes this adaptability could allow them to thrive in changing environments, building a foundation for civilization.
Flashes of Color
These creatures don’t just communicate; they send messages through complex flashes of color. This unique skill might help octopuses coordinate, interact, and develop societies if humans were to disappear.
Neural Powerhouse
With an advanced neural structure, octopuses possess remarkable problem-solving skills, says Coulson. This might let them adapt to shifting planetary conditions, ensuring survival in a transformed world.
Underwater Cities
Though not suited for land, Coulson speculates that octopuses could evolve underwater communities, resembling human cities. Some already weigh over 100 pounds and reach 20 feet in length, suggesting a capacity for architectural feats.
Incredible Escapes
Coulson highlights anecdotes of octopuses escaping their tanks to visit others at night, showcasing not only intelligence but social curiosity—traits that might drive community-building in their watery realms.
Long Evolution
For octopuses to achieve dominance, it might take millions of years of evolution. Yet Coulson asserts their intelligence, adaptability, and resilience give them an edge over other species if humans disappear.
Brains of the Sea
While it’s impossible to predict evolution, Coulson imagines octopuses becoming the “brains of the sea” in a post-human era, replacing humans—and potentially even primates—as the planet’s most intelligent species.
