> On a side note regarding early sapiens: I never understood why most people assume that humans today are, on average, more intelligent than our ancestors 40,000 years ago. because "intelligence" is a vague thing and it connects with education. For example, the average person with a school education today can do math better than Leonardo da Vinci, which enables some stuff to be invented today more easily than before.
