We’ve conquered every terrain, climbed every peak, and explored the ocean depths. There’s practically nowhere on this planet that people don’t live. We’ve built mega-cities, dammed vast rivers, and drilled deep below the surface of the Earth. Yes, humanity’s colossal impact on the globe can’t be denied: for good or ill, we’ve reshaped vast swathes of our environment. Yet while there’s not a lot of debate about our dominance as a species, the reasons behind why we’ve managed to become so preeminent are less obvious – and you might be surprised by one theory that scientists have developed.

Dominant Species

“Dominant species” is a term you might have often heard used by ecologists. It means that there’s a particular type of animal (or plant) that isn’t only particularly plentiful in a certain environment but also has a disproportionate impact on the other living things around it. If you remove the dominant species then it means change for the entire ecosystem.
