Dinosaurs' Dominance: A World Without Extinction

If dinosaurs never went extinct, mammals would have stayed small and insignificant.

That asteroid impact sixty six million years ago wiped out seventy five percent of all species,

giving mammals the chance to evolve and dominate. Without that catastrophic event,

dinosaurs would still rule the planet. Theropods would have continued evolving, possibly developing

even higher intelligence. Humans would never exist because our mammal ancestors needed that extinction

to thrive and eventually evolve into primates. The world would be completely unrecognizable, with massive sauropods

and intelligent raptors controlling every ecosystem on Earth.
