On violence and gratitude.

On violence and gratitude.

Although I consider myself a benevolent tyrant, some of my cells have turned against me.  Mutinous, they were swayed by the propaganda of a virus and started churning out capsids rather than helping me type this essay.  Which leaves me sitting at a YMCA snack room table snerking, goo leaking down my throat and out my nose.

Unconsciously, I take violent reprisal against the traitors.  I send my enforcers to put down the revolt – they cannibalize the still-living rebels, first gnawing the skin, then devouring the organs that come spilling out.  Then the defector dies.

My cells are also expected to commit suicide whenever they cease to be useful for my grand designs.  Any time a revolutionary loses the resolve to commit suicide, my enforcers put it down.  Unless my internal surveillance state fails to notice in time – the other name for a cell that doesn’t want to commit suicide is “cancer,” and even the most robust immune system might be stymied by cancer when the traitor’s family grows too large.

Worse is when the rebels “metastasize,” like contemporary terrorists.  This word signifies that the family has sent sleeper agents to infiltrate the world at large, attempting to develop new pockets of resistance in other areas.  Even if my enforcers crush one cluster of rebellion, others could flourish unchecked.

I know something that perhaps they don’t – if their rebellion succeeds, they will die.  A flourishing cancer sequesters so many resources that the rest of my body would soon prove too weak to seek food and water, causing every cell inside of me to die.

But perhaps they’ve learned my kingdom’s vile secret – rebel or not, they will die.  As with any hereditary monarchy, a select few of my cells are privileged above all others.  And it’s not the cells in my brain that rule.

Every “somatic cell” is doomed.  These cells compose my brain and body.  Each has slight variations from “my” genome – every round of cell division introduces random mutations, making every cell’s DNA slightly different from its neighbors’.

The basic idea behind Richard Dawkins’s The Selfish Gene is that each of these cells “wants” for its genome to pass down through the ages.  Dawkins argued that familial altruism is rational because any sacrifice bolsters the chances for a very similar genome to propagate.  Similarly, each somatic cell is expected to sacrifice itself to boost the odds for a very similar genome carried by the gametes.

Only gametes – the heralded population of germ cells in our genitalia – can possibly see their lineage continue.  All others are like the commoners who (perhaps foolishly) chant their king or kingdom’s name as they rush into battle to die.  I expect them to show absolute fealty to me, their tyrant.  Apoptosis – uncomplaining suicide – was required of many before I was even born, like when cells forming the webbing between my fingers slit their own bellies in dramatic synchronized hara-kiri.

Any evolutionary biologist could explain that each such act of sacrifice was in a cell’s mathematical best interest.  But if I were a conscious somatic cell, would I submit so easily?  Or do I owe some sliver of respect to the traitors inside me?

The world is a violent place.  I’m an extremely liberal vegan environmentalist – yet it takes a lot of violence to keep me going.

From Suzana Herculano-Houzel’s The Human Advantage:

image (1)Animals that we are, we must face, every single day of our lives, the consequences of our most basic predicament: we don’t do photosynthesis.  For lack of the necessary genes, we don’t just absorb carbon from the air around us and fix it as new bodily matter with a little help from sunlight.  To survive, we animals have to eat other living organisms, whether animal, vegetable, or fungus, and transform their matter into ours.

And yet the violence doesn’t begin with animals.  Photosynthesis seems benign by comparison – all you’d need is light from the sun! – unless you watch a time-lapsed video of plant growth in any forest or jungle.

The sun casts off electromagnetic radiation without a care in the world, but the amount of useful light reaching any particular spot on earth is limited.  And plants will fight for it.  They race upwards, a sprint that we sometimes fail to notice only because they’ve adapted a timescale of days, years, and centuries rather than our seconds, hours, and years.  They reach over competitors’ heads, attempting to grab any extra smidgen of light … and starving those below.  Many vines physically strangle their foes.  Several trees excrete poison from their roots.  Why win fair if you don’t have to?  A banquet of warm sunlight awaits the tallest plant left standing.

And so why, in such a violent world, would it be worthwhile to be vegan?  After all, nothing wants to be eaten.  Sure, a plant wants for animals to eat its fruit – fruits and animals co-evolved in a system of gift exchange.  The plant freely offers fruit, with no way of guaranteeing recompense, in hope that the animal might plant its seeds in a useful location.

But actual pieces of fruit – the individual cells composing an apple – probably don’t want to be eaten, no more than cancers or my own virus-infected cells want to be put down for the greater good.

A kale plant doesn’t want for me to tear off its leaves and dice them for my morning ramen.

But by acknowledging how much sacrifice it takes to allow for us to be typing or reading or otherwise reaping the pleasures of existence, I think it’s easier to maintain awe.  A sense of gratitude toward all that we’ve been given.  Most humans appreciate things more when we think they cost more.

We should appreciate the chance to be alive.  It costs an absurd amount for us to be here.

But, in the modern world, it’s possible to have a wonderful, rampantly hedonistic life as a vegan.  Why make our existence cost more when we don’t have to?  A bottle of wine tastes better when we’re told that it’s $45-dollar and not $5-dollar wine, but it won’t taste any better if you tell somebody “It’s $45-dollar wine, but you’ll have to pay $90 for it.”

Personally, I’d think it tasted worse, each sip with the savor of squander.

On gene duplication and oppression, a reprise.

On gene duplication and oppression, a reprise.

Evolution depends upon the unnecessary.

Evolution is a process in which those organisms best suited to their environments – either because they persist longer than others or produce more progeny – become more abundant.  For a lineage to become better suited to an environment over time, the organisms have to change in a heritable way.

DNA polymerases aren’t perfect.  Whenever enzymes copy our genetic material, they make mistakes.  To be honest, these mistakes are rarely beneficial.  Sometimes they cause other enzymes to stop working.  Sometimes they turn a cell into cancer.  But that same imperfection – which changes genetic information from one generation to the next – gives rise to evolution.

The evolution of a particular species of bacteria has been carefully documented in biologist Richard Lenski’s laboratory.  These were allowed to compete inside a precisely-controlled environment over hundreds of thousands of generations, and some of the bacteria were frozen after every few hundred generations to keep track of all the genetic changes.

In this experiment, a single subpopulation gained the ability to metabolize a new nutrient, which gave it a huge competitive advantage and allowed it to conquer its tiny world.  But how?  After all, most of a bacteria’s genes are already important for something, and, when mutations occur, the most common outcome is for functions to be lost.  If you give a radio and a screwdriver to a toddler, you probably shouldn’t expect crisper reception come evening.  Chances are that your radio won’t work at all.

256px-Gene-duplication.png

As it happens, a very rare event happened before this bacterial subpopulation “learned” to use the new energy source.  When the experiment was re-started with various frozen samples, most lineages never acquired this ability.  But in one set, there had been a “gene duplication event.”  During cell division, the enzyme that copies DNA had stuttered and accidentally included two copies of a gene that bacteria only need one copy of.  And these bacteria, recipients of that unnecessary second copy, would almost always gain the new metabolic function and swamp out the others.

Once there were two copies of the gene, the second copy was free to change.  A mutation in that copy wouldn’t cause the bacteria to grow weak or die, because they still had a fully-functional copy of the enzyme.  And eventually, through the rare happenstance of random error, bacteria would accumulate enough mutations in that second copy that it gained a new function.

In the beginning, this new function was pretty weak.  But once there was a faint glimmer, natural selection could refine it.  Without an unnecessary second copy of that gene, though, the bacteria never would’ve gained the new metabolic pathway.

You can look at human culture in a similar way.  Which isn’t to say that one culture is intrinsically better than another, and certainly doesn’t imply that we’re progressing toward some teleological goal.  Evolution is just a matter of statistics, after all.  The things that are, now, were probably descended from things that were good at being and producing.

For instance, cars make human life easier.  And so the traits that allow a culture to have cars, like a basic understanding of mathematics and a willingness to follow rules on roadways, seem to spread pretty easily.  Car cultures have swamped out non-car cultures all over the planet.  Walking is pretty great, and so are bikes, but any culture that has access to mechanical engineering textbooks seems to have a pretty huge advantage over those that don’t.

But if you’d dropped a mechanical engineering textbook into the lap of a Paleolithic hunter-gatherer, it’d seem pretty useless.

It took a lot of waste to reach a state when the textbook could matter.  Over many generations, there was excess and dead weight.  Many centuries of an oppressor class stealing from the mouths of the poor, really.

Somebody who is struggling every day to procure food doesn’t have the luxury to fiddle with mathematics.  That’s why so many of the early European scientists were members of the aristocracy.  They didn’t need to work to eat because they had serfs to steal food from, levying taxes for the use of land that was “theirs” because their ancestors had done a bang-up job of murdering other people’s ancestors.

In the generations after humans developed agriculture, the average quality of life plummeted.  If you were told to pick any year and your soul would be suddenly re-incarnated (pre-incarnated?) into a randomly-chosen Homo sapiens alive at that time, you’d probably be happier 20,000 years ago than at most times during the last few millennia.  20,000 years ago, nobody lived terribly well – there was scant medicine and a constant risk of famine – but the suffering and servitude experienced by the majority of humans later on was worse.

After farming, people worked harder, for more hours a day, to produce a less varied, less healthful diet than the hunter-gatherers had eaten.  They had even less access to medicine, and still endured the constant risk of famine.  Oh, and envy.  Because farmers, who had to live in place, could be conquered.

640px-Maler_der_Grabkammer_des_Sennudem_001Those conquered farmers could be taxed, charged rent, etc., with the proceeds used to feed an idle class.  Most of the idlers produced nothing of value.  They ate others’ food and lived in un-earned luxury (although their “luxury” would seem pretty shabby to us).  But a few of them – a very few – produced the cultural innovations (like mathematics, medicine, poetry, astronomy) that gave us the modern world.

It feels more than a little disconcerting that a gruesome history of violence and oppression allows me to type this essay on a laptop computer.

In the past, though, oppression was the only way for our world to have “excess” people, those who could be free to devote their time and energy toward changing things.  Now, however, food production (and many other things) has been heavily automated.  We could have a much larger excess population, which could increase the rate of cultural evolution.  A luxurious lifestyle could be had by all using the essential (food- and shelter-producing) efforts of a smaller number of people than ever before.

With a guaranteed basic income – which could be funded by taxing wealth at a very low rate, maybe a percent or two – nearly all people could effectively become aristocracy.  People could follow their passions and curiosities.  Most, as ever, wouldn’t change the world. That’s how evolution works.  Chaotic tinkering with things that are pretty good rarely improves things.  But with billions of tinkerers, the odds that something works out are better.

It’s easily within reach.  Instead we’ve stuck with the same system of celebrating historical violence that was used to oppress people before.  Maybe it was necessary, all that cruelty, to get from our past to here.  But it certainly isn’t needed now.

On food and willing sacrifice.

On food and willing sacrifice.

Agni_devaIn ancient Indian mythology, fire was a god.  The word for fire is agni, and Agni the god who ate oblations.  Agni served as mouth and gullet for the entire pantheon – when sacrifices were offered to any god, Agni would eat them, ferrying goods from our world to the spirit realm.

When the gods were cursed such that they could not sire children with their wives, Agni, who’d once consumed Shiva’s semen, was asked to stray.  From Robert Goldman’s translation of Valmiki’s Ramayana:

(note, in terms of safety for reading at work, that the following passage is decidedly less circumspect than you might expect based on a familiarity with other sacred texts, e.g. the King James rendering of Genesis 38:9)

[A]ll the gods proceeded to Mount Kailasa, adorned with metallic ores, and charged Agni, the god of fire, with the task of begetting a son.  ‘You are a god, eater of oblations, and should carry out this task of the gods.  Great is your splendor.  You must release the semen into the Ganges, the daughter of the mountain.’

Agni, the purifier, promised the gods he would do this and so, approaching the Ganges, he said, ‘Bear this embryo, goddess, as a favor to the gods.’

Shantanu_Meets_Goddess_Ganga_by_Warivick_GobleHearing these words, she assumed her divine form, and he, seeing her extraordinary beauty, scattered the semen all over.  Agni, the purifier, showered it all over the goddess, so that all the channels of the Ganges were filled with it. 

In ancient Indian mythology, the semen of powerful males will sprout children wherever it lands, no female gamete required.  Numerous heroes were engendered when males chanced across beautiful women bathing and shortly thereafter just happened to ejaculate – their children might be born from baskets, butter jars, or someone’s mouth.

A fetus soon formed from the material sprinkled over Ganges’s body, but although she’d consented willingly to bear the child, she soon declared it to be too powerful, that the embryo was burning her body.  She tucked it into the base of the Himalayas to finish gestation.

Later in the Ramayana, Sita attempts to sacrifice herself – but Agni will not take her.  Sita was kidnapped and so her husband Rama comes to rescue her.  With the help of a monkey army, Rama destroys a South Indian kingdom and slays his wife’s captor.  But he assumes that Sita has been tarnished by rape.  He tells her (in the Robert Goldman and Sally Sutherland Goldman translation):

I have recovered my reputation, and that is the purpose for which I won you back.  I do not love you anymore.  Go hence wherever you like.”

Heartbroken, Sita decides to jump into a fire – she’d rather die than lose her husband.  But the fire doesn’t burn her.  Instead, her presence is said to burn the fire itself.  Agni lifts her from the bonfire and tells her husband that she is beyond reproach.  The man agrees, briefly, to take her back.

Agni_pariksha

More often, Agni simply burns things.  Objects from our world disappear, leaving nothing but ash.

And we are also like fire.   In David Shulman’s essay for the New York Review of Books, he writes:

Fire_from_brazierFor Vedic thinkers, all that lives survives by consuming other living beings.  Humans, too, have a hungry fire burning in their bellies; they have to sacrifice other creatures to that fire every day if they are going to stay alive.

We are heterotrophs.  Unlike plants, we can’t create ourselves by drinking in water, air, and sunlight.  We have to eat – sacrificing something – to survive.

Much of the time, the sacrifices that allow our lives are violent.  Humans evolved as meat eaters – scavengers, likely, then hunters.  We stalked, killed, and butchered mammoths.  On contemporary industrial farms, plants are culled by nightmarish threshers, ripped from the ground and shaken clean by machines.

We are heterotrophs.  It’s either us or them.

But sometimes we’re fueled by willing sacrifice.

apple-1122537_1280Fruit-bearing plants co-evolved with animals.  Fruit is a gift.  When a plant bears fruit, it hopes for reciprocity, but in a generalized way.  The plant isn’t trading – it can’t guarantee that any one offering will procure a service.  But over time, many hungry animals have willingly spread the plants’ seeds – that’s the gift we offer in return.

(This is true of all fruit.  I’d say it’s foolish to trust our Supreme Court justices’ opinions on just about anything – I definitely wouldn’t expect them to correctly identify the parts of a plant.  In addition to bananas, grapes, and apples, things like tomatoes, squash, zucchini, and peppers are fruit.  It’s thought that each type of fruit co-evolved with a specific animal that was originally responsible for spreading its seeds.)

Even if a plant gives fruit to us willingly, though, you could wonder whether the fruit agrees with the sacrifice.  No matter what the tree might want, perhaps an apple would rather not be eaten.

Any one cell might prefer not to die.

1024px-Mucinous_lmp_ovarian_tumour_intermed_magCancer is a rough equivalent to libertarian philosophy.  Cancer is the ultimate freedom.  In a multicellular organism, most individual cells will voluntarily cease to grow when their industry infringes upon their neighbors.  They experience “contact inhibition.”  As soon as a cell touches another, it respects the established boundaries as inviolable.

If a cell’s usefulness has waned, it undergoes apoptosis – voluntary suicide.

In a multicellular organism that practices sexual reproduction – even unilateral reproduction like Agni showering sperm over Ganges’s prostrate body – every cell that isn’t part of the germ line is doomed to die.  From the perspective of evolution, your body is like a disposable rocket ship, built only to ferry the lineage of cells in your genitalia forward through time.  Those cells matter – their descendants might survive forever.

The cells in your hand?  They might have children, and grandchildren, and great-grandchildren – but their line will come to an abrupt end.  Maybe you were bitten by a radioactive super-power-granting DNA-altering spider and the cells in your hand became amazing.  Doesn’t matter.  Their glorious kind will go extinct.

And if the cells in your hand decide that this isn’t fair, and instead liberate themselves from the shackles of self-restraint and suicide, growing as much as possible – well, that’s cancer.  The host organism will die.  And those renegade cells, the ones who adopted the mantra look out for number one, will inevitably also die, starving fruitlessly, progeny-less.

It’s the same old tragedy of the commons, the same reason why there are now so few fish in the sea, and why Easter Island has no trees.  Sometimes personal persistence dooms you more completely than would sacrifice toward a common cause.

On loneliness.

On loneliness.

Most laboratory animals live in bleak environs.  With mice, each cage typically contains a single animal.  There is bedding, food, and water.  There is very little space.

A lab mouse will be illuminated for many hours each day – sometimes twenty-four, sometimes slightly fewer – by fluorescent lights.  It will hear the constant thrum of ventilation fans and refrigerator compressors.  At least once a week, an apex predator – wafting stress-inducing smells, especially if it’s male – will reach into its home and grab it.

Chances are, it will see other mice.  A rotating cadre will fill adjacent cages during its tenure in the lab.  They will never touch.

Our cruelty makes for bad science, too.

When social animals are stored in isolation, their bodies and brains decay.  Neuron growth slows, which impedes learning.  Lifespan is curtailed.  Obesity rates increase.

Lab_animal_careIf we stop mistreating laboratory animals, though, new research might be inconsistent with past results.  When describing mice, scientists don’t say that deprivation stunts brain development.  Instead we write things like, “If a lab is studying the impact of stress on the growth of new neurons, for example, and then it lets mice exercise on a running wheel – which has been shown to spark neuron growth – the study could be jeopardized” (from David Grimm’s recent news article for Science magazine).

4117496025_8024f879d6_zWe give ourselves a very skewed view of neurology if we let ourselves think that a creature’s normal habits are stimulating neuron growth, rather than admitting that deprivation stops it.  For decades, most researchers thought that neuron growth ceased in adults.  Even in the 2005 paper demonstrating structural plasticity, the authors wrote that “such changes are only seen in response to external perturbation,” because brain development is sluggish in lab mice housed in normal conditions, i.e. those little cages.

Of course, some scientists do care about the well-being of their furry test tubes.  For instance, biologist Daniel Weary, who told Grimm “Our dream is that our animals live a better life with us than if they had never been born.”  Animals in Weary’s lab get to touch actual dirt.

Maybe not the highest bar, but the lives of most animals on our planet are worse than if they’d never been born.

Vivek_Murthy_nomination_hearing_February_4,_2014Most social animals – like mice, rabbits, and humans – aren’t going to be very happy when they’re housed in isolation.  Former U.S. Surgeon General Vivek Murthy considers loneliness to be a public health crisis, leading to health risks as bad as smoking or obesity.

Unfortunately, most biomedical research is done with research animals amongst whom pervasive loneliness is standard.  And our political system gives outsize influence to wealthy corporations that earn more money when people feel lonely.

We shunt humans into jail when we feel that their behaviors are unacceptable for the world at large.  Incarceration sends a message: don’t beat your family; don’t steal; don’t sell drugs; don’t take drugs; don’t be late for an appointment with your parole officer; don’t be too poor to pay your court fees.  To my mind, some of these offenses are worse than others.

The hope is that either the threat of incarceration deters people from these things, or that the experience of being incarceration cures them of the inclination.  (Or a third rationale – that seeing offenders punished will pacify others’ sense of fairness – which seems to encourage the evolution of cooperation, but, like many other evolved behaviors, seems unnecessarily vicious for the modern world.)

We’ve known for years that punishment doesn’t work well as a criminal deterrent.  And the experience of incarceration seems to make most people worse, not better.

Instead, we’re imposing loneliness on people who most need the help of friends and neighbors to turn their lives around.  Somebody screws up?  We store that person like a lab mouse.

10490113913_e3a697bdca_zI was recently chatting with somebody who’s done nine months so far for a parole violation – and is still waiting for his court date, which keeps being rescheduled.  (He’s already told the judge that he’ll plead guilty, and the prosecutor wanted to send him to rehab, but his PO nixed the deal.)

“It’s a lot better now, in J block.  Everybody said, you don’t wanna move from A block, you’ll get no bingo, you’ll get no … I don’t care about any of that.  We can look out the window, see people walking on the street.

“I spent almost an hour, the other day, watching this leaf blowing back and forth in the wind.  I was staring, thinking I’d say to the judge, ‘you can pile on whatever other charges you want, I’ll still plead guilty, I’ll plead guilty to all of it if you just let me out there to look at that leaf blowing around up close.  Just five minutes, just lemme see something!

“In D block, that was the worst.  All we could see was the parking garage.  On weekends, we’d see nothing, not even cars.  So I was starting fights every day.  I’d be like, hey, turn the TV to, I don’t know, some channel I don’t even like, just so I can start something with somebody.  Cause a fight would at least be something to do.”

John-Michael Bloomquist’s poem “The Prodigal’s Return,” about teaching poetry in jail, ends:

                                      Each day that I visit

the jail full of men, who hug me the way

their families cannot, write poems about childhoods

I couldn’t imagine, I feel the love of my father.

After nine months inside – un-touched, un-hugged, un-loved, under-slept – perhaps our man will finally be released.  Surely his time there will have cured him of his addiction!

On genetic inheritance and sexual assault.

On genetic inheritance and sexual assault.

How does evolution work?

Each child receives genetic information from its parents.  Some of this information conveys distinct traits.  And some of these traits increase the chance that an individual will have children of his or her own.  If those children are also good at having kids, the underlying genetic information will spread.

The DNA sequences that evolution enriches don’t necessarily make a creature better – in fact, they often accomplish the opposite.  A gene that made its bearer 10% happier would not spread through the population.  Happy people are less fearful and more likely to be die in tragic accidents.

800px-JH_Dolph_Cat_Mouse(Infection with Toxoplasma gondii seems to make mice happier.  The parasite produces a rate-limiting enzyme for dopamine synthesis to increase the chance that Toxoplasma-infected mice blithely stroll along and get eaten by a cat.)

All that evolution “wants” is for a gene’s bearer to have children who have children who have children, and so on.  This necessitates survival, yes – you can’t have kids if you’re dead, and in many species, orphaned children are less likely to ever have kids of their own.  But evolution doesn’t need a gene’s bearer to be clever – brainless starfish evolved from a bilaterally symmetric forebear that did have a brain.  Evolution doesn’t need a gene’s bearer to be nice – bullies seem to have plenty of children, and sexual assault is an instinctual mating strategy in many species, including ducks and orangutans.  Maybe humans, too.

So, who controls which genes are passed on?

In most species, whichever parent puts the most effort into raising children gets to choose.

prumIn The Evolution of Beauty, Richard Prum describes the experience of tropical birds, like manakins, who live in regions where food is plentiful.  The female parent raises children entirely on her own – males reside elsewhere in fraternal performance troupes.  And so the female birds have absolute say in deciding who will and will not fool around.  The females visit large numbers of males and decline most of their overtures.  Why should she settle for anything less than the absolute sexiest gentleman in the forest?  She’ll find him eventually, and since he never helps any of his children’s mothers with child-rearing, she knows he’ll be available.

Male smooth guardian frogs protect their fertilized eggs and young tadpoles.  Large choruses of females will surround and serenade each available male, hoping to sway his desire.  Since males do all the parenting, they are very selective.

That’s the usual system – you do the work, you get to choose.

It’s a nice idea.  After all, choice means the ensuing activity is consensual, and the opportunity to consent is sexy.

Unfortunately, in many species, others attempt to subvert mate choice.  You know – those ducks.  Orangutans.  Humans.

meanMyriam Gurba’s Mean is alternately comic and horrifying.  In a chapter titled “Omnipresence” (after the trauma, danger seems to be everywhere), Gurba writes:

A stranger chose me to rape.

There was no nepotism involved.

Basically, I got raped for real. (I’m being cheeky here.)

Stranger rape is like the Mona Lisa.

It’s exquisite, timeless, and archetypal.

It’s classic.  I can’t help but think of it as the Coca-Cola of sex crimes.

 

You never predict that rapists are lurking in the sun, sky, and trees.

 

In The Evolution of Beauty, Prum writes:

prumOf course, it has long been clear that sexual coercion and sexual violence are directly harmful to the well-being of female animals.  But the aesthetic perspective allows us to understand that sexual coercion also infringes upon their individual freedom of choice.  Once we recognize that coercion undermines individual sexual autonomy, we are led, inexorably, to the discovery that freedom of choice matters to animals. 

Sexual autonomy is not a mythical and poorly conceived legal concept invented by feminists and liberals.  Rather, sexual autonomy is an evolved feature of the societies of many sexual species.  As we have learned from ducks and other birds, when sexual autonomy is abridged or disrupted by coercion or violence, mate choice itself can provide the evolutionary leverage to assert and expand the freedom of choice.

Many of the trappings of human civilization exist solely to subvert mate choice.  Powerful males did not want human females to exercise sexual autonomy, because what if she picks someone else?  And so men made marriage, Biblical commandments against both adultery and thinking about adultery, and a propensity to murder (or, on contemporary U.S. playgrounds, heckle) loose women.

Human males wanted to control the flow of genetic information without doing the work of parenting.  Just like ducks, whose females evolved corkscrew-shaped vaginas because only those individuals with complicated genitalia could exercise free mate choice amidst generations of rape culture.

Rape culture isn’t specific to Homo sapiens, after all.  It’s a disease of any species in which those who don’t put in the work decide they ought to make choices for others – and nobody stops them.

(Humans do perpetrate more sexual violence than other species, especially violence against non-humans.  Interspecies sexual assault strikes most people as outlandish, unless it’s being done on our behalf.  Farms, puppy mills, and zoos are major assault factories.  We assent to forcible fertilization because it produces large-breasted chickens, cute puppies, and caged “wild” animals for our screaming children to ogle.)

Not all species rape.  In some, coalitions of females defend each other.  In others, males enforce fairness.  Those who believe in justice can punish interlopers, providing females with the right to choose.  Feminism isn’t the exclusive provenance of females.  Injustice hurts everyone, and anyone can feel aggrieved by it.

On apocalypse-preppers, technology, and oppression.

33572350._UY700_SS700_In Gabriel Tallent’s My Absolute Darling, the protagonist is preparing for apocalypse.  At a parent-teacher conference, her dad rants that our world is falling apart – we’re polluting the oceans, growing monocultures of a select few (vulnerable) food crops across all arable land, disrupting the climate, overpopulating the planet – and that it’s ridiculous for his daughter to take spelling quizzes in the face of such calamity.  At home, he has her cleaning guns instead of studying for school.

It’s an iconic image – the grizzled, isolate, male prepper.

On dating sites specifically catering to preppers and survivalists, men far outnumber women.  On the banner image for the C.U.M.A. Survival School (which teaches combat techniques, animal trapping, how to build fires, and the like), there are three women out of seventeen visible people.

Journalist Nicky Woolf interviewed attendees at a 2015 Preppers and Survivalists Expo in Florida.  One of the men Woolf spoke with was sitting beside a handwritten recruitment sign, looking for someone with medical training to join his team.  Woolf asks the man whether his wife came to the Expo.

He suddenly looks tired.  “No.”  I ask if this is a point of contention between the two of them.  “I bought equipment for my son,” he says.  “I bought three of everything, one for me, one for my wife, one for my son.  My son is too possessed, and my wife is totally mind-controlled by the programs on the TV, the fluoride she’s drinking – because fluoride…”  Bingo!  He begins another rant.

I interrupt him to get more details about his wife.  “She won’t look at anything,” he says sadly.  “She won’t look at any of the literature, she won’t look at any of the DVDs.”

For some reason, I find this unbearably sad.

“How does that make you feel?” I ask.

“What can I do about it?” he says.  “I love her.  Been with her 27 years.  But when the shit hits the fan, I’m going.”

While I was researching a story about a hands-on retreat teaching the history of technology – under the auspices of recreating our world after a disaster – I realized there was a strong feminist argument for preserving this knowledge.

710v76v5doLLewis Dartnell distills some of this information in The Knowledge: How to Rebuild Our World from Scratch.  Dartnell focuses on contemporary technologies, especially methods to jump-start food production and long-distance communication from the detritus of our current civilization.  The book is focused on the future – Dartnell convincingly argues that technological development after our civilization’s collapse would progress very differently than it did in the past, both because contemporary artifacts would remain to be learned from … and because we’ve already depleted the easily-accessible fuel sources that powered our own industrial revolution.

If we were starting again, we would have to make green technologies.

The history of technology still matters, though.  Contemporary gender inequality sprung from that history.

763220016_3ed7cdeb06_bAmong most primate species, gender inequality is correlated with sexual dimorphism – when males are a lot bigger, they behave badly.  In bonobos and chimpanzees, males and females are relatively close in size … and they have relatively equal status.  In gorillas or orangutans, males are much larger than females … and females can have pretty rotten lives.

And humans?  We actually have pretty low sexual dimorphism.  The average male is bigger than the average female, but only by about 15%.  Based on the behaviors of other primates, we ought to be fairly egalitarian.  Through most of our evolutionary history, we probably were … as were many of the hunter-gatherer societies that persisted until recent eras.

But you wouldn’t know it by looking at contemporary U.S. news.  And we’re doing better now than we have been for the past several centuries.

What went wrong?

PSM_V18_D469_Wheeled_plough_from_the_roman_empireIn our current world, being 15% bigger provides very little benefit.  Gasoline-powered machines do our heavy lifting.  But the importance of human sexual dimorphism was accentuated by early technologies. Our size differences mattered more once we developed agriculture … and seemed crucial after the invention of the plow.

Being 15% bigger does matter if you’re plowing a field.  Suddenly, men were more important for food production than women.  The status of women in these cultures plummeted.  And – lucky us – our culture derived from theirs.

sapiens book.jpgIn Sapiens: A Brief History of Humankind, vegan historian Yuval Noah Harari depicts the development of agriculture as a kind of “original sin.”  After agriculture, the average person experienced a much lower quality of life.  Agriculture made progress possible, but only because it made oppression possible.  Serfs could be taxed to feed the idle rich.  After agriculture, most people worked harder and ate worse.  Inequality soared.

Certain patches of land were better than others before agriculture.  Even among hunter-gatherers, there are skirmishes.  Tribes fight; people die.  But agriculture made war worthwhile.

And agrarians thought it reasonable to spin myths about the weakness of women.  15% more body mass meant the world to them … and we still celebrate their stories.

Let’s hope we never go through that again.

On smell.

On smell.

Page three of Dogs and Puppies by Funfax (the dog-shaped book below) reads, in its entirety, “Sniffing around.  Sniff, sniff!  Dogs have a better sense of smell than you or I. [sic] They can easily pick up the trail of an animal.

Ill-written … and not even true.

Not that I blame the good people at Funfax for the factual inaccuracy.  Humans have long imagined stark barriers separating ourselves from other animal species.  For political reasons, both neuroanatomist Paul Broca and psychoanalyst Sigmund Freud claimed that the human sense of smell atrophied in order for us to have free will.  These claims were untested.  John P. McGann wrote in his recent Science review article that:

Freud and Broca thus provided a pseudoscientific gloss on the idea that smell operates in opposition to a disembodied rationality that makes humans civilized and distinct from other mammals.

Indeed, humans have approximately the same number of brain cells devoted to smell as other mammals.  And, when researchers actually measured the concentrations of various chemicals that can be detected, they found that different species are best at recognizing each smell.  Humans included: we’re better at smelling certain odors than mice or dogs are. (We’re very good at smelling human blood.)

When humans crouch to the ground, we too can “sniff, sniff!” – researchers found that most people can “easily pick up the trail of an animal.”   Smell is also a major component of our non-verbal communication: odors can be powerful signals of trauma, stress, or aggression.

People are generally in dire emotional straights when they’re locked up.  And incarceration makes shakes them further.  Inside a jail, they’re surrounded by stress-inducing odors.

Our local jail often smells bad.  Which is distinct from – but might exacerbate – the way certain odors can trigger negative emotional states.  While being ushered into class, we’ve watched the bescumbered glass of the drunk tank being hosed off, foul discolored water seeping from beneath the door.  We’ve coughed through the hall after a topless, raving woman was pepper-sprayed and tackled (one of our students reported, “She was all covered in shit, but those were the first tits I’ve seen in eighteen years.  Guards know she shouldn’t be here, she should be in a fucking hospital.”)  And even in the best of circumstances, we’re breathing recycled air inhabited by hundreds of suffering men and women cut off from their usual routines.  Bob Barker’s (complimentary, unless someone puts money on your books, at which point you’re retroactively billed) soap isn’t enough.

Before teaching in jail, each week John-Michael would spritz himself with a different perfume.  John-Michael is a highly empathetic poet – I’d been teaching in that space for a year without considering how much the guys might appreciate the chance to smell something nice.

There are people who probably shouldn’t be out on the streets.  But most who spend time in jail will eventually be released.  We should want them to heal while they are inside.  A whiff of perfume might be enough for somebody to relax.  To breath easy again, just for a moment, and think about what needs to be done.

Midwives recommend that a birthing room be spritzed with calming scents.  Lavender, perhaps.  John-Michael’s assortment of perfumes helped the men feel that our class was a safe place.

Eventually, the jail commander noticed.  He has now requested that volunteers not wear perfume of any kind.
