For centuries, humans have wondered why dinosaurs were extinct.
In the last century scientists correlated the date a meteor collided with Earth with the approximate date the extinction occurred. They theorized that the Earth was covered with a thick dense cloud.
In the last several decades, archeologists have found evidence that the dinosaurs are actually descendants of birds.
I have a different theory that explains why dinosaurs are extinct. Dinosaurs tasted like chicken.
Natural selection at work.
