1 小时 52 分钟Today, I have the pleasure of chatting with Joseph Henrich,
who is a professor of human evolutionary biology at Harvard University,
and an author of two of my favorite books,
The Weirdest People in the World, and before that, The Secret of Our Success.
And I was just mentioning to you that I remember reading this, I don't know, many,
many years ago when I was in college,
and at the time I didn't think I would get a chance to ask you questions about it.
I recently had your colleague, David Raikkon, and we were discussing certain things in the...
record of human history where he said like look you eventually just got to have Joseph Henryk on and ask him these questions
because he's the one who would know so let me ask you one of the questions which I was super intrigued by which he raised and I didn't we didn't come up to an answer to so One of the things he's discovered through his genetic evidence is that 70,000 years ago,
across Eurasia,
there's so many different human species from the Denisovans to the Neanderthals to the Hobbits.
apparently there's this one group which was potentially the size of one to ten thousand people in the Near East which subsequently explodes and now everybody who's descended from Eurasia descends from this one group.
And so I guess the question is like what happened?
What did they figure out?
A typical assumption when people think about this, if you put it in the Paleolithic,
they assume that it has to do with some kind of genetic changes.
Now, Reich's lab...
There's no obviously big changes in the DNA.
So it's a little bit of a puzzle.
