WELL, IS CULTURAL ARGUMENTATION SUFFICIENT WITHOUT GENETIC LOGIC? FOR EXAMPLE, WE KNOW THAT LANGUAGE AND RELIGIOUS DIVERSITY PER UNIT AREA IS POSITIVELY ASSOCIATED WITH INTENSITY OF PARASITE SELECTION. THE STRONGER SUCH SELECTION, THE MORE YOU ARE SELECTED TO AVOID STRANGERS WHO MAY BE CARRYING PARASITES TO WHICH THEY ARE ADAPTED BUT NOT YOURSELF.
IN GENERAL PETER—AS WITH HIS ILK—SEEMS OBLIVIOUS TO THE POWERFUL EFFECTS OF CO-EVOLVING PARASITES ON HUMAN SOCIAL EVOLUITON IN THE PAST 40,000 YEARS. FOR EXAMPLE, PHONEME DIVERSITY HAS BEEN SHOWN TO OBEY THE SAME RULE AS GENETIC DIVERSITY—AS “WE” MOVED OUT OF ARICA IN THE LATEST WAVE ABOUT 100,000 YEARS AGO—SERIAL FOUNDER EFFECTS REDUCED GENETIC DIVERSITY AND ALSO PHONEMIC DIVERSITY STEADILY FROM THE COMPLEX CLICK-SOUNDS OF THE !KUNG BUSHMEN TO SOUTH AMERICAN LANGUAGES. A VERY RECENT PAPER SHOWS THE MATTER IS MORE COMPLEX IN AN INTERESTING WAY.
THIS IS PURE BULLSHIT
THERE IS NO UNIT OF HERITABLE CULTURAL VARIATION. THIS IS JUST A METAPHOR. CAN YOU NAME A UNIT THAT REMAINS CONSTANT OVER AN INDIVIDUAL’S LIFETIME AND THEN IS INHERITED UNCHANGED, ABSENT
