It’s a fascinating theory: Humans are certainly smarter than the (now-extinct) homo erectus, yet the homo erectus managed to traverse the entire known world — including islands only accessible by watercrafts. Their brains were only half the size of ours, yet they successfully escaped from Africa and populated remote regions of western Europe and southeast Asia.
And they did it all between 1 and 2 million years ago!
Meanwhile, modern humans have been around for roughly 300,000 years. But until about 10,000 years ago, humanity’s accomplishments (aside from wiping out all that yummy, delicious megafauna) were embarrassingly limited: No agriculture. No metallurgy. No large cities. No writing. No great monuments. No enduring culture.
Modern humans didn’t even arrive in Europe until 45,000 years ago! For whatever reason, we just (mostly) stayed in Africa.
And then, suddenly, great leaps in innovation simultaneously appeared throughout the globe, including Egypt, Mesopotamia, China, and Mesoamerica. As far as we can tell, all four of these regions independently developed complex systems of written languages within 3,000 years. […]
