    What is the oldest expertise that's been passed down from person to person? Is there a chain for flint-knapping for example?

        Persistence hunting seems a good bet.

        Do you think it beats walking though? That's the best answer I've seen so far on this thread.

        I know too little about that. But I would think humans would learn to walk without that expertise being ‘passed down from person to person’.

        I'd guess that our kind of walking co-evolved with teaching it.

        Good point! Once we go down that route we get to monkeys teaching each other or even much further. https://www.nwf.org/News-and-Magazines/National-Wildlife/Animals/Archives/2015/Animal-Teaching.aspx …pic.twitter.com/qNOsLtWbwe

        Walking, talking - parent to child.. otherwise would we be scooting around babbling away?

        Walking could be it actually.

        Given that coevolution is a slow process and walking wouldn't be key to early hominid babies (carried) but only useful for adults...

        And that it could be easily discovered by any able bodied hominid, I'm not sure it's the right answer. But maybe

        I'm increasingly inclined to think it was just survival knowledge ab local env. what not to eat, where not to wander, local animal calls...

        Indicating specific types of danger, etc. Tools come later. Advanced skills after that

        I think you're on to something here. But it's got to be baser. How about just that knowledge should be shared?

        I think that's part of what I was suggesting. Like plant x = good, plant y = bad. Don't wade into a river unless you have no other option
