Yeah.

Yeah.

I mean my sense is it replicates quite well.

So we published our paper in 2010 and in late 20-aughts, Armin Falk is an economist and a bunch of others, Ankenbecker, Ben Ankey published a paper where they measured economic preferences in 80,000 people around the world.

And that just showed big variation in things like patients, various kinds of reciprocity, altruism, so the kinds of things we would expect.

And then other large-scale projects have similarly shown lots of variation.

Well, that's always a concern, and it's especially a concern when you're studying hunter-gatherers because a lot of the hunter-gatherers that are left in the world today are places where agriculturalists couldn't easily move to.

So that's something we're thinking about all the time.

The ways around that are to go to places where agriculturalists didn't go or couldn't go.

So we have a lot of good ethnographic history on people in Australia.

And then we have the Arctic populations, which, you know, big sections of Paleolithic Europe were probably kind of like Northern Canada is today.

So at least environmentally, it's not crazy because, you know, Ice Age Europe.

And places like the Aleutian Islands, the west coast of California, we have lots of ethnographic evidence.

And there was no agriculture there.

So, yeah.

So just putting together all these different lines of evidence help us develop a picture.

I wouldn't want to bank everything on the Hadza.

Of course, we can't do experiments with some of those groups, but we can see whether the Hadza look like these other hunter-gatherer groups.

Yeah, I don't have a clear picture of that.

It is the case that the Holocene was a particularly long stretch, a particularly long interglacial.
