Origins of Political Order: Mistaken About Evolution

I just finished Part 1 of Francis Fukuyama’s Origins of Political Order. First off, I like the book. He’s an evolutionist, and a Hobbesian, which is to say that he understands human nature, and he bases his theory of the state upon that foundation.

Now, a mistake: Fukuyama’s description of human evolution is wrong. It’s only a little bit wrong, but it’s totally wrong. Fukuyama tells the familiar “one tribe out of Africa” story. We now know this is wrong, because we have genetic evidence of interbreeding with Neandertals, not to mention Denisovians, and presumably dozens of biologically modern Homo Sapien tribes that left Africa at different times.

Of course, Fukuyama’s book was published a month before that paper came out, and presumably written a while before.

On the other hand…

For a genetic example of what happens when one people conquers another, we need look no further than the high frequency of European Y chromosomes in the Americas. I would expect most pre-historic genetic exchanges to follow similar models. When an anthropologist says “population displacement,” we should interpret that to mean “they killed all the men and raped and married the women.” This means that conquerors not only take their enemies’ land, they also absorb genetic information, which is then selected for.

Fukuyama is exactly the sort of person who ought to have doubted the old story. Rome claimed to have founded itself upon a crime of mass rape. And the old testament doesn’t shy away from what to do with conquered people. Fukuyama actually quotes Genghis Khan and notes his massive offspring.

So, while one can hardly blame Fukuyama for making this error, since it was the conventional scientific view, if he had been following his own method of science+anthropology+historical analysis more rigorously, he might not have.
