Reproductive dynamics as a game.
Loci <-> Players
Alleles <-> Strategies
Genotype <-> Strategy profile.
Common interests (all loci get same payoff/fitness).
Sexual reproduction converges to monomorphic pure NE genotype.
Mutations add alleles/strategies. Transition to new NE with higher fitness.

Cultural evolution driven by subjective selection. Enjoyed the paper, but not wholly convinced by the subjective/objective dichotomy used. Yes, selection can occur towards intermediate goals, but it still seems like a kind of messy objective selection.

Subjective selection and the evolution of complex culture
Why is culture the way it is? Here I argue that a major force shaping culture is subjective (cultural) selection, or the selective retention of cultural variants that people subjectively perceive as ...

Harmonic games are the opposite of potential games. In potential games, player incentives are aligned, in harmonic games, player incentives are opposed. Turns out that no-regret learning is Poincaré recurrent in harmonic games. i.e. dynamic returns to close to its starting point.
No-regret Learning in Harmonic Games: Extrapolation in the Face of...
The long-run behavior of multi-agent online learning -- and, in particular, no-regret learning -- is relatively well-understood in potential games, where players have common interests. By contrast,...
