So rather than having local rituals and local myths, many communities would get together periodically to initiate the young men.

And this would help bond that whole group.

There'd be an exchange of technology and teaching that goes on at these.

They'd spent a few months in the same place.

So there was a lot of time for transmission.

Well, eventually the groups have to meet and they're going to compete over territories.

And a bunch of different things can occur.

So groups can copy each other.

So we know that from the ethnographic record and historical cases, sometimes a group will say, oh, those guys have really good technology tools.

Maybe they'll get some migrants or something like that.

And then they can adopt the practices.

So that definitely happens.

But there's also plenty of evidence of violent conflict.

And the Reich Labs evidence and lots of other ancient DNA suggest that there are these dead end genetic lineages.

So, I mean, the Neanderthals are dead end in a sense, although we interbred with them.

So they're in us in some sense.

But they don't have their own pure lineage or anything like that.

The way I describe it in The Secret is that it's a package of things.
