[It’s been a while since I’ve revived an old Pharyngula-safe post from my old blog, and it seemed like we have the appropriate theme going here today.]

Biologists have long assumed that evolutionary psychology, a controversial branch of psychology that ascribes many common social behaviors to genetics, is a muddled blend of half-understood evolutionary biology, selective data mining and resentment of women’s changing roles in society.

A new study, published in today’s issue of the German publication Unwirklichen Genetikjournal, does not challenge that assessment. But it does suggest that some men may be genetically predisposed to believe in evolutionary psychology, a finding that may well suggest future methods of treatment of the psychological malady.

Believers in evolutionary psychology maintain that feminism sets itself in opposition to millions of years of anthropoid evolution, and is thus futile and inhumane to men. Allegations made by believers include references to putative differences in math skills between men and women, a supposedly irresistible but entirely non-visually stimulated female attraction toward powerful and/or arrogant males, and the existence of a genetically preordained male right to multiple female sexual partners.

Many such men hold to these beliefs despite an absolute lack of supporting scientific evidence, says Dr. Ulrike Mann-Esser, chair of the sexual anthropology department at Universität Ulm and the study’s lead researcher. “But we had no way to determine why this was so until last year’s discovery of the locus taedius.”

The locus taedius, discovered accidentally last year by a graduate student working with David Gelernter, is a section of the human hindbrain that shows significant electrical activity when a person retrieves long-term memories that he or she does not find interesting.

In Mann-Esser’s study, 200 male subjects, who had small electrodes implanted in their locus taedius and glued to various places on the skin, were asked to stand outside the door of a glass cubicle and open the door for anyone trying to enter. Inside the cubicle was a male Pilates instructor posing as a researcher. A handful of highly attractive female graduate students were instructed to approach the cubicle, ignore the subjects while the door was opened, then proceed into the cubicle and place a hand on the chest of the “researcher.” Levels of locus taedius activity were recorded for each subject.

“By setting up a stimulus that often spurs EvPsych statements in the susceptible,” says Mann-Esser, “we hoped to be able to detect increased locus taedius activity among those men who had half-remembered bits of evolutionary biology come to mind from high school. The skin electrodes measured galvanic response and thus sexual arousal, which allowed us to determine which subjects were merely trying to recall female sexual anatomy from textbook figures so that we could exclude them from consideration.”

At first, approximately fifteen percent of male subjects showed significant locus taedius activity without sexual arousal. “We thought that seemed rather high,” says Mann-Esser, “until the Pilates instructor’s boyfriend showed up and two-thirds of that fifteen percent showed dramatic galvanic response changes.”

Further study by Mann-Esser’s team found a surprising commonality among the five percent of subjects showing clinical signs of susceptibility to evolutionary psychology, which the team refers to as “Desmond Morris Syndrome,” or DMS. Ninety percent of the DMS-positive subjects shared a single allele, first isolated by researchers at the University of Lucerne. The recessive allele, named luz-R, was absent from the remaining 95 percent of test subjects. (The corresponding dominant allele, luc-ID, has been tentatively linked to critical thought faculties and penis size.)

Mann-Esser admits that the existence of a “DMS gene” is confusing from an evolutionary standpoint. “Most genes persist because they contribute to reproductive success in one way or another. Sometimes this is in surprising ways, such as the gene for sickle-cell anemia, a crippling condition for those possessing two copies of the gene, but conferring resistance to malaria to heterozygous individuals with one normal gene. But the luz-R gene is strongly correlated with complete reproductive failure due to sexual selection against the gene by human females.

“It may be that early human populations carrying the recessive gene in their genome benefited from having certain individuals who were more likely to stand there and lecture the lion about how man is clearly the most fearsome predator on the savannah and then be eaten, thus allowing the rest to escape. It’s puzzling, though. We clearly need to study the issue further.”

One evolutionary psychology partisan maintains that evolutionary psychology itself holds the key to understanding the existence of the luz-R gene. “It’s ridiculously obvious, and has been proven time and again beyond the point where any rational person not swayed by politically correct feminism could dispute it,” says BigBoyBob87, a frequent commenter on a number of feminist blogs.

“You only need to look at sage grouse,” continues BigBoyBob87. “They reproduce by leks, in which a group of males converge in a spot to attract females and only the alpha males get to mate, while the others complain about the alpha males being big jerks. Anthropologists have proven that that very same evolutionary psychology observation is a major theme in Paleolithic art, as in for instance the Mousterian Pluvial cave painting Females of Breeding Age Always Mate With Damn Metro sapiens and Toss Us Nice Guys on Communal Trash Midden.” [See figure 1.]

When asked how any of the preceding actually supported his contention that DMS conferred selective fitness on men with the luz-R allele, BigBoyBob87 suggested that this author was only parroting the feminist line in order to get laid.

 

Happy Thanksgiving from those of us in the United States! It’s a day in which we Estadounidenses traditionally gather to celebrate the debt of gratitude we owe the original inhabitants of the land for helping the first European colonists survive. The remembrance takes many forms. Most commonly, we commemorate our Native cousins by not paying any attention to them at all, though on occasion we note their contributions by red-baiting their allies. And every once in a while, we celebrate this holiday by destroying irreplaceable Native ceremonial art dating back to a time contemporaneous with the European Bronze Age.

From my KCET story linked above:

The petroglyphs are thought to be as much as 3,500 years old, and still play an important role in the cultural life of the Owens Valley Paiute and Shoshone people. Paiute tribal historic preservation officer Raymond Andrews told Los Angeles Times reporter Louis Sahagun this week that the vandalized petroglyphs are regularly visited by modern-day Native people of the Eastern Sierra. “We still use this sacred place as a kind of church to educate tribal members and children about our historical and spiritual connections. So, our tribal elders are appalled by what happened here.”

According to the BLM, the vandals drove ladders, power saws, and portable generators to the site to attempt to remove the petroglyphs. Four were apparently removed successfully. A fifth, shown above, was damaged by saw cuts but left in place: a sixth was broken after removal and left on site. BLM rangers also reported hammer damage to dozens of nearby petroglyphs.

You don’t have to buy into Paiute/Shoshone religious beliefs to find an act like this appalling, just as you wouldn’t need to be a Magdalenian animist to get pissed off if someone took a crowbar to the Megaloceros paintings at Lascaux. A couple years ago a couple of slack-jawed nitwits took their paintball guns into a canyon in southern Nevada that figures prominently in the origin myths of a number of Native people along the lower Colorado River. Said nitwits defaced a number of petroglyph panels there. One doesn’t have to actually believe that Mastamho the creator’s son dug the Colorado out of the desert sands with his walking stick and sent the local tribes off in different directions to feel grief and anger at that damage to culturally significant artwork.

I won’t venture a guess as to the motivation of the thieves, though I suspect — to steal a joke from Professor Bérubé — a primitive form of outrage influenced by what the Greeks called μεθαμφεταμινε. Whatever their motivation, they need to be found and corrected before they do it again. The desert has a deep human history every bit as fascinating and inspiring as its natural history. Damaging it damages our common heritage. On the off chance a reader here has a friend of a friend who knows something, the BLM and the local Tribal government have set up a reward for info.
