How does this work? Rodents produce pheromonal odors with individual signatures, derived from genes called the major histocompatibility complex (MHC). This is a super variable gene cluster that produces unique proteins that form a signature for an individual. This was first studied by immunologists. What does the immune system do? It differentiates between you and invaders—“self” and “nonself”—and attacks the latter. All your cells carry your unique MHC-derived protein, and surveillance immune cells attack any cell lacking this protein password.[/b]
Not much here in the way of memes, right Satyr?
Castration decreases sexual urges in the subset of sex offenders with intense, obsessive, and pathological urges. But otherwise castration doesn’t decrease recidivism rates; as stated in one meta-analysis, “hostile rapists and those who commit sex crimes motivated by power or anger are not amenable to treatment with the antiandrogenic drugs.
Cue, among others, the feminists.
Infuse oxytocin into the brain of a virgin rat, and she’ll act maternally—retrieving, grooming, and licking pups. Block the actions of oxytocin in a rodent mother, and she’ll stop maternal behaviors, including nursing.
Here’s the thing then: How much of this is applicable to us?
During one wave, I suddenly found myself cramped over in front of my tent, stark naked, painful, liquid acidic craps, and, the humiliation of it all, surrounded by six elephants, silent, quizzical, polite, murmuring, almost solicitous, their trunks waving in the air investigating my actions and moans. They watched my agonized shitting as if it were an engrossing, silent Shakespearean tragedy performed in the round.
I guess you had to be there.
Suppose a person harmed people two generations ago; are this person’s grandchildren obliged to help his victims’ grandchildren? Subjects viewed a biological grandchild as more obligated than one adopted into the family at birth; the biological relationship carried a taint. Moreover, subjects were more willing to jail two long-lost identical twins for a crime committed by one of them than to jail two unrelated but perfect look-alikes—the former, raised in different environments, share a moral taint because of their identical genes.
Let’s untangle this once and for all.
People see essentialism embedded in bloodlines—i.e., genes.
I’ll bet they do.
