The disappearance of humans would leave a vacuum in the global ecosystem. Soon after we disappear, other species would have the potential to rise to power. History shows that whenever a dominant group vanishes, nature quickly selects new leaders based on adaptability, intelligence, or sheer numbers.
Some candidates for this new world order are already living in our shadow, waiting for the competition to fade away. From the depths of the ocean to the ruins of our cities, these survivors possess unique biological tools that could help them inherit the earth.
In this gallery, we look at the 15 species most likely to dominate a post-human world. Curious? Click to know more.
