I like the graphic, I did cause it does show that if we take off the ancient in human history, the humans evolution is normal, while the ancient is abnormal. The knowledge they had were much higher than even now. and if we consider that we suppose to have much more year of experience from the first time human exist than the ancient civilizations, it would have been normal the high knowledge 10k years later and just why during middle age almost all knowledge from ancient been lost. to gradually regain the knowledge the ancient had like how to make beer come from the ancient time.
