Microorganisms can make collective decisions via quorum sensing. Shared DNA works as a committment device.

I can see why studying economics would cause someone to be skeptical of evolution.

Interesting. Given that your field seems to be about understanding game theory and exactly how to escape Moloch, have you thought about looking deeper into the subject to see whether the microorganisms due something that useful in a more wider scale and could move on the economist's understanding of cooperation?

Beliefs have to pay rent ;)
