I agree with Ikelos… What if we were to find traces of civilization from that period, or even from just 1 million years ago?

The more I learn about the beginnings of civilization (Ancient Egypt, Gobekli Tepe, etc.), the more I am beginning to believe that something is wrong with the currently widely-accepted timeline. Indeed, it appears that the origins of civilization occurred much earlier than is now widely accepted. Such an assumption, however, begs the question: What happened to those civilizations? I read recently that all human beings are the descendants of only 10,000 ancestors. What if there were great civilizations prior to the extinction event that nearly wiped out humans?

Hi Vinny,

It’s a common misconception, but dimetrodons were actually not dinosaurs–they were reptiles that lived in the late Permian era.

That meant to say 190 million years before the dinos bit the bullet

Don’t put a picture of a large dinosaur for an article about the extiction event that happened 190 million years before dinoaurs were the dominant organisms.

Imagine we find traces of civilization during that period… lol. I wonder what the Quaternary extinction event and the mass extinctions occurring today will look like in another 250 million years…

The Permian was the most biodiverse period in the earths history, we have still yet to recover, (and probably never will).
