How much time passed between the extinction of the dinosaurs and the emergence of humans? Explained
Roughly 65 million years transpired between the demise of the dinosaurs and the advent of contemporary humans. Dinosaurs perished roughly 66 million years ago, probably due to a devastating asteroid collision that signaled the conclusion of the Cretaceous era. Subsequently, mammalian species started to thrive, with primitive primates emerging around 55 million years ago. Through the course of millions of years, certain primates underwent transformations into early hominins, setting the stage for the eventual arrival of modern humans roughly 300,000 years in the past.
