Snakes owe some of their success to one of Earth’s most devastating moments, the Cretaceous-Paleogene extinction event. The suborder serpentes thrives in all sorts of ecological environments, and is native to every continent except Antarctica.
Some 66 million years ago, dinosaurs ruled the Earth but with the sudden impact of a massive asteroid, the reign of the dinos came to an end. What followed was a mass extinction event where 75% of all life withered away.
One of the surprising victors of this ecological disaster was the lowly snake. Capable of going without food for months and finding solace underground, in freshwater, and on forest floors, the snake was uniquely suited to the suddenly hostile environment.
Now, millions of years later, snakes have become one of the most successful and diverse suborders on Earth.
Faced with little competition, snakes were able to spread out and flourish, as their keen survival skills made them highly adaptable, and now there are over 3,000 different snake species living in places from the ocean to deserts.
Research published in the Nature Communications journal indicates that all modern snakes can trace their evolutionary history to the ones that survived the asteroid impact 66 million years ago.
Humans talk about the age of dinosaurs giving way to the age of the mammal, but that appears to be erroneous. The dinosaurs gave way to the snakes, and they don’t appear to be giving up their spot in the food chain anytime soon.
