What’s the most amazing yet unexplained event in human history? [Serious](r/AskReddit)
Actually, the general consensus within archaeology has slowly turned away from this idea over the last 15 years or so. A lot of this has to do with discoveries of much older technological / symbolic advances in Africa. Perhaps the most famous set of material includes pierces shells and an engraved ocre plaque from the site of Blombos. These objects are thought to be at least 70,000 years old. If you’re interested in a longer read, perhaps the most famous ‘tide turning’ article on the subject is titled “The Revolution that Wasn’t” and can be found for free in PDF from here. It’s 15 years old now, so it’s in some ways out of date, but at this point it’s considered a classic. This book is another good resource if you can find it.
