Thank evolution for birds!

A long time ago in a land far, far away, GIANT insects roamed the Earth's skies with unparalleled size and freedom.

How big are we talking? Their wingspan was the size of a modern-day HAWK!

Researchers believe that the insects became massive due to the large levels of oxygen in the atmosphere some 300 million years ago.

The data shows that the higher the oxygen level, the larger the insects.

But things changed.

Around 140 million years ago, birds started evolving and learned how to fly. With better aerodynamics and predatory skills, the birds began competing with the insects for prey, and soon the birds began eating the giant insects as well.

80 million years later, bats also started to evolve and along with further evolved birds (and the possible arrival of an asteroid), dinosaurs and the giant insects became extinct.

Again, we can't thank evolution enough!

Could U imagine insects the size of modern birds in the sky?!?!?!

Creepy!
