If modern human intelligence evolved 60,000 years ago, why did civilization not develop until 10,000 BC? Potential explanations range from a reconsideration of prehistory to the power of collective learning to early humans getting stuck in "gossip traps." https://bigthink.com/the-past/sapient-paradox-prehistory/
