No, the point I was trying to make is that even with absolutely perfect transmission (which is the best they could hope for) it can be very difficult to translate words back into actions. It's also hard to learn golf or dancing from a book (again, perfect error-free memorisation) because there's a lot of knowledge which doesn't fit well into words. Muscle memory, once you've got it.

I presume this was also true of the making of stone tools, or pottery. And of the recognition of edible plants & mushrooms. All of these are skills which I'd be surprised to see transmitted over a long time-lapse. (Without being at all surprised by the memorisation of stories, at a level I could never match.)

The most recent example might be the Australian aborigines fire rituals. After this year's bush fires there have been many calls to use their fire ritual burnings once again. I gather this has been done in the Northern Territories for a few years, and is far more successful than advanced, technological and knowledge filled approaches (Western arrogance that our way must be better) that pushed the traditional out for decades. They seem to have kept more than enough to be far better at it than those meant to know. How well they work in a significantly changed climate is another question, but it appears to work better.

Speculating wildly here, we don't know the Neanderthals didn't ritualise the activity into a dance or an act to retain some of the process as well as the words. As we do with dancing, martial arts, even theatre or early stages of ancient apprenticeships. That might transmit the muscle memory of golf or stone tool making -- without the practised skill. How far that remains applicable using a stick in place of a golf club, or pine cone in place of a lump of flint is impossible to guess, but puts you closer than mere words.

I have to assume they wouldn't suffer the Wikipedia tendency to explain the technical so technically perfect (including all obscure jargon) that it's often bordering on impossible for an intelligent outsider, deeply skilled in other technical fields, to follow. :)

What's the time-period for the firebreaks? I mean when these skills last used, even if on a smallish scale?

OK, ritualising a "how to ride a bicycle dance" seems like it could be a way to pass more information than a perfectly repeated poem / book. (Perhaps thinking of oral tradition as meaning Homer not how to chip flint is a blind spot in how we think about such things?) Would still be extremely curious to know of any examples where this actually happened.
