Everyone knows that about 65 million years ago, a massive asteroid hit the Earth and wiped out all the dinosaurs. Except, well, not so much. Most species of dinosaurs went extinct in the aftermath of the impact, but some survived.
Those survivors continued on, breeding and evolving over the epochs. Today, there are at least 10,000 species of dinosaur that roam the planet, and they come in a huge diversity of sizes, shapes, and colors. We call them - you guessed it - birds.
