While it is true the dinosaurs may have gone extinct because of a meteorite strike upon the earth, it is also important to note they died with all their defenses intact. Their giant horns and claws made them maladapted in times of great transition. They were still beyond challenge in contests of violence; but they were, by the same invulnerability, incapable of adapting to their new environment. Their great level of consumption also made them unsustainable. This kind of extinction by way of fortification is also the fate of every human empire. Perhaps this is what is meant by the phrase “the meek will inherit the earth.”
