d. Open question: what is the mechanism by which memes influence behavior?
i. Memes we have vs. memes we act on (Itunes: Top 25 Most Played).
III. Genetic vs. memetic evolution.
a. Genetic evolution does influence memetic evolution.
i. Why babies listen to their parents and other adults. Because it works for the survival of the genes: `don’t put your hand on the stove’. (It may be that this `open transmission’ line closes as the child ages and becomes engaged with humans of increasing genetic distance). So in many religions there is a meme that takes advantage of this open line of transmission: `send your children to Sunday school’.
