“Mammals and dinosaurs diverged from a common ancestor about 260 million years ago. Dinosaurs subsequently evolved to fill every possible ecological niche, from which they ruled the earth for 160 million years and became the most successful vertebrates in the history of the planet. During all that time we mammals managed to evolve into nothing larger than a cat.”
