> Anyone that knows history knows that humans were as tame, if not tamer, in the past. Plus uneducated. Most of humanity has never been agile, curious and resourceful.

Anthropologists know that ancient hunter gatherers were stronger, fitter, and typically had lower rates of morbidity than us. Which kind of undermines your “agile” and “tame” bit.

I’d also say going from nothing to stone tools counts as quite resourceful, if you ask me. Given that our ancestors had the same basic wiring and larger brains, I’d actually wager on them being more curious and clever than modern humans.
