Epigenetic Influence of Stress and the Social Environment

The first two links are scientific papers and the third is a popular article from Discover magazine. They are all quite readable though and worth a look. If you search epigenetics in this blog you’ll find a number of related articles.

Scientists taught white mice to fear the smell of cherry blossoms. (“So Bob, what do you do for a living?” “I frighten mice.”)

The offspring of these frightened mice were never subjected to this cherry blossom trauma but mysteriously, they also feared the smell. More amazing still, the grandchild generation of the original trauma mice, also never subjected to the treatment, reacted with fear. Now further studies are not only confirming these results but showing that deprivation and stress alter inheritance multi-generationally. It affects both physiology and neurology.

The evidence is in. Pain and suffering flow across time. Cruelty keeps jumping forward like a skipped stone. We don’t know authoritatively how many generations forward these effects can travel but 3 and 4 generations are documented using an animal model. And rather than just imagining separate generations of inherited fear, and the many influences on the phenotype of those people, imagine how many poor choices their inheritance initiated. Imagine the effects flowing into the places they live in and their families and friends. Consider the implications for large communities who have suffered trauma almost collectively. In some places and times that could mean whole generations where virtually everyone is bent and twisted by the suffering of their parents and grandparents. How often will behavior born of trauma result in fresh trauma to another?

There is nothing parents love more than their children, and every parent fears passing along something bad to their children. Our new knowledge means that anyone suffering a serious trauma, or having survived desperate stressful times, can be certain that some effects will be passed to their children from the moment of conception.

It makes an act of profound cruelty almost unimaginably important and scales up the guilt accordingly. In the form of random violent crimes for example the effects are stark enough: One innocent victim becomes how many? 3? 6? Don’t forget the 3rd generation…perhaps 18 people? And the 4th generation as well; let’s say 35 people affected by that injury. They don’t even know, they can’t know who they might have been instead, because that crime made them what they are. They might be more fearful, or angry, or just less hopeful than the hypothetical person without the trauma. We don’t know, but it’s safe to say they are bent AWAY from their strength and happiness.

Now consider:

  • Soldiers returning with PTSD
  • Black America
  • Poor America
  • Syrian survivors

When a child grows up shaped by a parent with trauma and then lives in poverty and anxiety, we have lost a well-functioning citizen 20 years in the future. And we’ve lost their offspring 40 years in the future. Epigenetics makes a simple, compelling case for the auto-perpetuation of misery and poverty and violence. It makes a case that democracy builds failure into its future by doing too little to alleviate it. A starving, fearful child is a crime against the future and her community and in a sense, the whole world but we are awfully good at feeling peaceful about that crime.

20% of American children grow up in poverty. It’s certain that many of them are second and third generation poverty. Poverty is Hydrochloric acid for optimism and aspiration. How is this not a self-perpetuating sinkhole of damaged and downgraded people?

“Those people are just like that.” is the kind of statement you might hear people say related to race or culture or class. The poor have been viewed forever as inherently flawed, undeserving, and unfit based on the sordidness and chaos of poverty everywhere. It’s probably more accurate to say people can be that way when they and their parents have been ground into emotional hamburger and left to pull themselves up by their own bootstraps. There’s a chance that we are living out a dystopian science fiction story where in all cultures, regardless of race, a whole class of people, less happy, strong, and confident is being bred through societal neglect. Any limits to the number of generations this damage is “paid forward” is irrelevant because the suffering of each new generation is likely enough to paint over their hopes of the foreseeable future. Big social programs have been deemed failures when they didn’t produce results in “Political time” but perhaps bringing generational trauma to an end is the work of a couple of generations and therefore almost impossible to convince taxpayers to support. And perhaps our famously cheap and nasty social programs wouldn’t soften the blow enough anyway.

Yet the import of this knowledge places responsibility on our shoulders once we know.

My map of this territory assumes that social Darwinism and the eugenics movement are an expression of the cultural conservatism that I’ve described in my various “Tension force” articles. These same views while not acceptable in “mixed company” (wow, what a phrase) inform the thinking of most powerful members of the right wing. These are also the beliefs that most classic left-wingers assume are shared by people with a sociobiological perspective . They are wrong though, this view is not scientific, it is very much an expression of conservative beliefs.  Further explanation will follow explaining why the right wing is already arguing against the implications of epigenetic influences. However, people on the left also need to expand their thinking. If you stick with me through my next article on epigenetics I think you’ll see that a species behavior perspective can be a STRONGER position for reform. Hang in, OK?

I. Introduction

Social Darwinism, a term coined in the late 19th century to describe the idea that humans, like animals and plants, compete in a struggle for existence in which natural selection results in “survival of the fittest.” Social Darwinists base their beliefs on theories of evolution developed by British naturalist Charles Darwin. Some social Darwinists argue that governments should not interfere with human competition by attempting to regulate the economy or cure social ills such as poverty. Instead, they advocate a laissez-faire political and economic system that favors competition and self-interest in social and business affairs. Social Darwinists typically deny that they advocate a “law of the jungle.” But most propose arguments that justify imbalances of power between individuals, races, and nations because they consider some people more fit to survive than others.

The term social Darwinist is applied loosely to anyone who interprets human society primarily in terms of biology, struggle, competition, or natural law (a philosophy based on what are considered the permanent characteristics of human nature). Social Darwinism characterizes a variety of past and present social policies and theories, from attempts to reduce the power of government to theories exploring the biological causes of human behavior. Many people believe that the concept of social Darwinism explains the philosophical rationalization behind racism, imperialism, and capitalism. The term has negative implications for most people because they consider it a rejection of compassion and social responsibility.


I. Darwin was very influenced by Thomas Malthus who wrote that the poor would always breed right up to society’s ability to provide for them and then loads of them would die (and live) miserably until the numbers balanced out. Therefore Malthus thought society shouldn’t do even as much as it was already doing to alleviate suffering , which wasn’t much of anything. He saw it as cruel to give the poor any ideas that things would be ok if they kept on as they were. This is where the phrase “Cruel to be kind” arises. Picture some plump, wealthy victorian saying it as he discourages his wife from putting out leftovers for the poor. We have these same forces in politics today. Senator Paul Ryan is described as a budget conservative but he’s really just in favor of zero help for the poor. Ryan’s politics are more informed by his favorite writer, Ayn Rand than by any “Judeo/Christian values”. Ayn Rand’s collected works are basically social Darwinism in the form of dense philosophical potboilers. -HM 

II. Origins

Social Darwinism originated in Britain during the second half of the 19th century. Darwin did not address human evolution in his most famous study, On the Origin of Species (1859), which focused on the evolution of plants and animals. He applied his theories of natural selection specifically to people in The Descent of Man (1871), a work that critics interpreted as justifying cruel social policies at home and imperialism abroad. The Englishman most associated with early social Darwinism, however, was sociologist Herbert Spencer. Spencer coined the phrase “survival of the fittest” to describe the outcome of competition between social groups. In Social Statics (1850) and other works, Spencer argued that through competition social evolution would automatically produce prosperity and personal liberty unparalleled in human history.

In the United States, Spencer gained considerable support among intellectuals and some businessmen, including steel manufacturer Andrew Carnegie, who served as Spencer’s host during his visit to the United States in 1883. The most prominent American social Darwinist of the 1880s was William Graham Sumner, who on several occasions told audiences that there was no alternative to the “survival of the fittest” theory. Critics of social Darwinism seized on these comments to argue that Sumner advocated a “dog-eat-dog” philosophy of human behavior that justified oppressive social policies. Some later historians have argued that Sumner’s critics took his statements out of context and misrepresented his views.

II. At its origin, social Darwinism had the powerful aura of a scientific proof around it. Science was doing wonders and now science says that WE are the fittest. It’s just not right to mess around with the natural order. Social Darwinists and their current equivalents always like to suggest that they are down to earth realists just facing truths that mushier heads can’t face. Of course Darwinian theory “proved” nothing all, much less that charity is a wasted effort.

We know that Darwin was an aristocrat and in fact saw life through this lens: IE That the rich and powerful have triumphed over the poor through natural superiority. That this is the right and proper way of life. He was a bit reticent about doing away with all kindness to the unfortunate but he mumbled here and there in his writings about having to give up the sentimental approach one day. Of course this philosophy is a perfect display of the “I Deserve This” rationalization that people do when things start to go well for them. See neuromechanical cruelty specifically “Money on the mind” for more. -HM

III. Hereditarianism

Studies of heredity contributed another variety of social Darwinism in the late 19th century. In Hereditary Genius (1869), Sir Francis Galton, a British scientist and Darwin’s cousin, argued that biological inheritance is far more important than environment in determining character and intelligence. This theory, known as hereditarianism, met considerable resistance, especially in the United States. Sociologists and biologists who criticized hereditarianism believed that changes in the environment could produce physical changes in the individual that would be passed on to future generations, a theory proposed by French biologist Jean-Baptiste Lamarck in the early 19th century. After 1890, hereditarianism gained increasing support, due in part to the work of German biologist August Weismann. Weismann re emphasized the role of natural selection by arguing that a person’s characteristics are determined genetically at conception.

III. Galton was the one who coined the term “eugenics” and believed in it utterly. -HM

IV. The Struggle School

Toward the end of the 19th century, another strain of social Darwinism was developed by supporters of the struggle school of sociology. English journalist Walter Bagehot expressed the fundamental ideas of the struggle school in Physics and Politics (1872), a book that describes the historical evolution of social groups into nations. Bagehot argued that these nations evolved principally by succeeding in conflicts with other groups. For many political scientists, sociologists, and military strategists, this strain of social Darwinism justified overseas expansion by nations (imperialism) during the 1890s. In the United States, historian John Fiske and naval strategist Alfred Thayer Mahan drew from the principles of social Darwinism to advocate foreign expansion and the creation of a strong military.

IV. It’s horrible and haunting to see the foreshadowing that hinted at the world wars straight ahead. It’s also clear that the theory here is being used to simply rationalize the beliefs of those who wanted military adventures. Nobody was more of a social Darwinist than Hitler. If he had one ultimate belief it was in universal struggle and winner take all. -HM 

V. Reform Darwinism

After 1890, social reformers used Darwinism to advocate a stronger role for government and the introduction of various social policies. This movement became known as reform Darwinism. Reform Darwinists argued that human beings need new ideas and institutions as they adapt to changing conditions. For example, U.S. Supreme Court Justice Oliver Wendell Holmes, Jr. reasoned that the Constitution of the United States should be reinterpreted in light of changing circumstances in American society.

“I know the right kind of people when I see them. “

Some reformers used the principles of evolution to justify sexist and racist ideas that undercut their professed belief in equality. For example, the most extreme type of reform Darwinism was eugenics, a term coined by Sir Francis Galton in 1883 from the Greek word eügenáv, meaning well-born. Eugenicists claimed that particular racial or social groups–usually wealthy Anglo-Saxons–were “naturally” superior to other groups. They proposed to control human heredity by passing laws that forbid marriage between races or that restrict breeding for various social “misfits” such as criminals or the mentally ill.

V. Reforms

1. We can see the broad cross pollination of ideas here as some progressive thinkers also saw a way to frame their point in evolutionary terms.

2. We also notice of course, the terrifying confidence of some people concerning what parts of the human garden needed trimming. -HM

VI. Social Darwinism in the 20th Century

Although social Darwinism was highly influential at the beginning of the 20th century, it rapidly lost popularity and support after World War I (1914-1918). During the 1920s and 1930s many political observers blamed it for contributing to German militarism and the rise of Nazism (see National Socialism). During this same period, advances in anthropology also discredited social Darwinism. German American anthropologist Franz Boas and American anthropologists Margaret Mead and Ruth Benedict showed that human culture sets people apart from animals. By shifting the emphasis away from biology and onto culture, these anthropologists undermined social Darwinism’s biological foundations. Eugenics was discredited by a better understanding of genetics and eventually disgraced by Nazi dictator Adolf Hitler’s use of eugenic arguments to create a “master race.” During World War II (1939-1945), the Nazis killed several million Jews, Roma (Gypsies), and members of other groups, believing them inferior to an idealized Aryan race.

Social theories based on biology gained renewed support after 1953, when American biologist James Watson and British biologist Francis Crick successfully described the structure of the DNA molecule, the building block of all life. During the 1960s anthropologists interested in the influence of DNA on human behavior produced studies of the biological basis of aggression, territoriality, mate selection, and other behavior common to people and animals. Books on this theme, such as Desmond Morris’s Naked Ape (1967) and Lionel Tiger’s Men in Groups (1969), became best-sellers. In the early 1970s American psychologist Richard J. Herrnstein revived the social Darwinist argument that intelligence is mostly determined by biology rather than by environmental influences.

During the 1960s, British biologist W. D. Hamilton and American biologist Robert L. Trivers produced separate studies showing that the self-sacrificing behavior of some members of a group serves the genetic well-being of the group as a whole. American biologist Edward O. Wilson drew on these theories in Sociobiology: the New Synthesis (1975), where he argued that genetics exerts a greater influence on human behavior than scientists had previously believed. Wilson claimed that human behavior cannot be understood without taking both biology and culture into account. Wilson’s views became the foundations of a new science–sociobiology–and were later popularized in such studies as Richard Dawkins The Selfish Gene (1976). Wilson’s critics have alleged that sociobiology is simply another version of social Darwinism. They claim that it downplays the role of culture in human societies and justifies poverty and warfare in the name of natural selection. Such criticism has led to a decline in the influence of sociobiology and other forms of social Darwinism.

VI. There are several weird takeaways from this.

First, Darwin’s theory was a blend of a scientific observation and his own personal beliefs. It was shaped by his position of privilege. Second, that it was popularly accepted by the rich and powerful because it supported what they already believed, that success was self-justifying. Third that everyone who EVER used the theory to explain or justify a political philosophy did so on very little justification, simply borrowing the credibility of science and wrapping it for transparently selfish reasons around whatever they were selling. 

As a separate point, notice that the author of this article, Robert Bannister, dismisses sociobiology explicitly as a form of social Darwinism. His writing here reminds me of a dog turning around in circles before lying down. “Wilson’s critics” unnamed and unquestioned, carry the day by alleging it, and we’re done and home by 4. 

A couple of problems: E.O. Wilson’s book Sociobiology: the New Synthesis, was a carefully researched work by a renowned Harvard ethologist and it said almost nothing about human beings, let alone excusing war and poverty. The book (and Wilson himself) were found to contain a strain of deadly ideas by expert witch-finders, and suppressed. His opponents called themselves a study group but limited their study to a bit of reflexive kicking. They momentarily observed something 300 yards off, resembling a duck and decided without observation of any walking or talking like a duck, that it must be a duck. 

Also, Wilson was and is a scientist, seriously exploring a theory with malice toward none. Not a single other example of social Darwinism can be described that way. The idea that we must have a kind of “faith based” research where nothing offends the political officer is possibly the only MORE demented road for humanity to take. 

Noam Chomsky, a linguist and political scientist, surprised many by coming to the defense of sociobiology on the grounds that political radicals need to postulate a relatively fixed idea of human nature in order to be able to struggle for a better society, claiming that leaders should know what human needs were in order to build a better society.

Arguments against Darwin generally come with theology as the endgame. It reminds me of the artificially intelligent toaster on Red Dwarf; it would engage the crew in deep philosophical chats which all came down to asking if they’d like some toast. My argument against Darwin is his insufficiency. Charles Darwin is the Sigmund Freud of evolutionary theory. His role was groundbreaking and important but his theory is primitive and wrong seen from today. My last article described the cronyism that rewarded him with this iconic status. I don’t know that his name would even be included in our current view of evolutionary theory were it not a battlement that must not be surrendered. Neo Darwinism is essentially Fort Darwin in the middle of extreme Born-again territory. This understandably makes us close ranks despite our differences, but when our wagons are in a circle it’s a sure thing they aren’t going anywhere.

Adding to the situation are the whole constellation of behaviors Thomas Kuhn outlined in The Structure of Scientific Revolutions. There is a naturally conservative and reticent approach among scientific professionals. First, there is the paradigm of our moment which is built on all the earlier work in our field. There MUST be a foundation and things that call that foundation into question are not likely to be welcomed with open arms. If something truly and suddenly proved the state of a discipline wrong, at one level it would be a triumph and at another, a tragedy. It would crash and trash much current research and practice. Jobs would be lost and it would be necessary to fall back to the last critical turning point before starting again from more basic principles. Finally, there tends to be a generational transition; the hard heads often have to age out of the system before a new theory is truly accepted.

Fortunately due to the power of the scientific method it’s extremely rare for a large theoretical collapse. However, it IS in the nature of research moving forward that new principles will be uncovered which are so RIGHT that earlier paradigms are wrong in comparison. It can be sudden or through long diligent efforts but all research will look like alchemy from a distant enough point. Still, it seems unfair to earlier scientific explorers who may be wrong by the light of today, but were as right as possible in their own time. A little generosity hurts no one. Lamarck was about the most correct person on earth about his subject at the time of his writing. Darwin and Wallace likewise, let’s grant them all winner status without faulting them for not being perfect and not staying current long after their time.

Some basic problems with Darwinism

  1. It’s a tautology (circular logic): Survival of the fittest means the fittest are the ones who survive. What exactly is fitness? Something that apparently is present in survivors.
  2. It describes a negative feedback (we could call it “natural elimination”) but not a positive feedback.  Or perhaps only a negative-positive feedback which is really just a distinction without a difference. We see why some die, but why do others change and continue to change? 
  3. No helpful mutation in an individual would be reinforced naturally in the next generation, each would be diluted.
  4. There is no evidence from long term well constructed studies of the kind of random helpful mutations Darwinism requires even in the groups subjected to more mutagens.
  5. The fallback explanation of an unimaginable time scale as the missing piece that completes the puzzle is insufficient to close the gaps we find.

Both Wallace and Lamarck believed in some principle that guided evolution generally toward more success on average. Almost as if the infinite monkeys at typewriters had automatic spelling and grammar check turned on. And perhaps an app that edited out utter nonsense. This is closer to what life on earth looks and feels like…but to this day we have no means of identifying and studying such a principle. Therefore it is unscientific not in the sense of being wrong, just by being un-measurable and undetectable. In his time, Dmitri Mendeleev (who imagined the periodic table)  predicted as yet undiscovered elements because within the framework he was using there were gaps in significant places. Logically, he thought,  there should be something in that spot. That’s how I feel about the missing mechanisms in evolutionary theory. I suspect they are there because the current theory is a tiny sheet that does not cover this bed.

The one interesting breakthrough that seems to be in this class of guiding principles is epigenetic or soft inheritance. It’s very new but means of positive feedbacks leading to positive variation are becoming visible in this field and its many developing subdisciplines. We find information across generations, and the experiences of parents affecting the phenome of the children. Wallace and Lamarck are being reconsidered. I think they should be granted full equality with Darwin as founders.

We shouldn’t regularly act from fear of being compromised by theology if we budge from an earlier spot. It’s Theology that never budges with it’s hand full of supposed aces. Science moves, not impulsively but empirically. Our position so long after Darwin, is blessed with a million knowings he didn’t have a available, but relative to the future we are just as wrong and insufficient as he is to us. It can’t be helped. Or perhaps the only help is accepting and remembering it. It won’t help us measure what we can’t detect but it may help us think in less black and white terms and to look for meaningful gaps. The undetectable of today is the foundation of the theory tomorrow.

“It darkles, (tinct, tint) all this our funnaminal world.” ― James Joyce, Finnegans Wake

In 1994 three researchers wandered the Ardèche valley in southern France beside the river of the same name. Their work would look odd and delicate to us. They were hoping to discover hidden caves and their method was to feel for small drafts of air rising through piles of rock. Some explorers do this by literally sniffing about, hoping to scent the smell of a cave. That day, these three discovered a near miracle. It was a huge cave full of ancient human art perfectly sealed by a landslide for around 20 thousand years. This is the Chauvet cave, named for the lead explorer.

Abundant charcoal on the site allowed good carbon dating. The primary use of the cave by humans dated from 32 thousand years ago. This placed the art at 10 thousand years older than the oldest art we knew of. I want to write that age as a number.

32,000 years ago. 30,000 BCE. This time is the upper paleolithic or “old stone age”. Something strange happened in the neolithic. About 9000 years ago an emergent rush of lifestyle change transformed humanity from small tribes of wandering hunters to villages of farmers. As a group, we abandoned what we had always done for something new.

The long paleolithic period in southern Europe leaves little to tell us who we were, but what we do find is vivid and strange. The paintings in the Chauvet cave are amazing. Like most cave paintings they are of animals rendered with smooth confident lines and subtle shading. What isn’t so obvious is what the paintings meant to the artists. When it was in use, Chauvet cave had a large opening that would have allowed sunlight into the first chamber. There are no paintings in the first chamber. Well, only one… just at the point the sunlight could not reach.

Paintings are for darkness.

The painters used all the features of the cave as part of the art. A horse appears to be running out of an alcove. Bumpy cave walls become 3d anatomy; a bison shoulder, a lion’s hip. Looked at from different angles things transform and shift identity. This part of a horse turns into that part of a wolf. Some animals might be a group standing together, or a single animal moving through space as if we paused an animation with multiple frames visible at once.

The world surrounding this canvas is worth considering. Europe was in an ice age, there were glaciers 9000 feet thick. It was cold but dry and sunny. The people would have dressed as traditional Inuit Indians do, with reindeer leather and furs. They carved bone flutes on the pentatonic scale. The sea level was 3oo feet lower and a determined hunter could have walked from Paris to London (or you know, those geographical locations).  The world was crammed with animals familiar and strange: Cave bears, lions, hyenas, mammoths, hairy rhinoceros, horses, bison, leopards, wolves, ibex, reindeer. In the same area lived a distinctly separate species of humanity; Neanderthals. Neanderthals left no paintings. Why did we paint and why didn’t neanderthals paint?

Humans didn’t live in the cave. They went down into the dark with their torches to conduct some kind of passionate business they had with this wild world they lived in.  Continue reading

The basic difference between Darwin’s theory and Wallace’s was this: Darwin focused on competition between individuals and Wallace focused on environmental pressures on local populations.

Alfred Russel Wallace was a nearly lifelong world traveler and naturalist and was taken with the way that distinct subspecies could be found in adjoining territories with no transitional form in between. Why did they change? How did they change? Later Wallace developed BioGeography from these thoughts. He also became a passionate early ecologist and wrote a book speculating on the possible nature of life on other planets. He also suspected that there was some form of intelligence that played a role in the evolution of species but while this was a spiritual belief, he didn’t attribute that intelligence to any theist god.

There were both unconscious and practical reasons why the Linnean society favoring Darwin’s theory over Wallace’s (besides cronyism). As I mentioned in my first article, Darwin’s bloody struggle scenario with the victory defining the winner as “more fit” supported the very strong belief system among the upper classes that the poor were sort of a failed version of human beings and that it was the kindest thing really, to let them die off in large numbers to “thin the heard”. This is where the chilly phrase “Cruel to be kind” comes from. Wallace thought that understanding the principles of evolution could improve people’s lives and alleviate suffering. This is the essence of how these scientific theories shade into politics. And this exact issue is alive today.

Darwin’s theory was also more accessible than Wallace’s,  It made a good, simple mental cartoon. “Stronger thing beats weaker thing, Win and go to next round!”.  Compare that to Wallace’s vision of environmental stresses on all the members of a local species driving evolution. It’s more sophisticated, but we enjoy protagonist based stories so much more.

The other reason was Wallace’s teleological (meaningful) engine of evolution. If you leave a gap in your theory big enough to drive a god through, the church might rush that spot in an effort to hijack any scientific theory of evolution and claim it for theology instead. There is some justification for this, Wallace’s work HAS been used as source material for some creationists. The very simple (and incorrect) answer that every bit of evolution was driven by nothing but random mutations and extremely slow change was a defense against the church, but it became a prison for all the evolutionary biologists forced since then to salute it like a flag.

And while Lamarck was never in direct competition with Darwin he was a groundbreaking thinker who had shaped the discussion. Although he was not the first thinker to advocate organic evolution, he was the first to develop a truly coherent evolutionary theory. Lamarck suggested that characteristics which were “needed” were acquired (or diminished) during the lifetime of an organism then passed on to the offspring. He incorporated this mechanism into his thoughts on evolution, seeing it as resulting in the adaptation of life to local environments. Lamarck also referred to a tendency for organisms to become more complex, moving “up” a ladder of progress. He referred to this phenomenon as (translated) “The force that perpetually tends to make order”.  Continue reading

(Amazing supporting stories:   Argentine super hive (scary) |  Ant communication via pheromones  |  Cell communication  )

Every living thing uses chemistry for communication.

Cells communicate through their own language of chemical signals. Different compounds, such as hormones and neurotransmitters, act like command instructions, telling a cell about the environment around it and communicating instructions.

Insects and animals communicate with chemicals and pheromones, lightly spiced with templated physical signals, in simpler words, body language.

Ants for example (I like talking about ants!) have a smell language that includes the following common phrases:

  • I found food, follow me
  • Danger (even what KIND of danger in some ants)
  • I am your relative (I belong here, and this is my job)
  • I am the queen (and here is an evaluation of my health and whether we need princesses, drones, etc)
  • I’ve been squashed! Danger!
  • I am dead, haul my body out. (Funny article about spraying a living ant with dead ant smell.)

Ants are territorial and maintain borders. The borders are defined with pheromones. They generally steer clear of other territories, but sometimes ants have to fight other ants over food access, invasion, etc.   Imagine an ant hive invaded, it’s WAR! But how do they know it? Ants are pretty dumb and they can’t hear a general announcement. An alarm pheromone “goes viral” and the hive goes into an aggressive posture. And then…

“These colonies conduct ritualized tournaments as a part of the defense of their foraging territories. Opposing colonies summon their worker forces to the tournament area, where hundreds of ants perform highly stereotyped display of fights (italics mine). When one colony is considerably stronger than the other, in other words, able to summon a larger worker force, the tournaments end quickly and the weaker colony is sacked. During the final incursions, the queen is killed or driven off and the larvae, pupae, callow, and honeypot workers are transported to the raider’s nest.

The behavior is mysterious, for ants. Why don’t they simply attack each other? Why is it “highly stereotyped”? The ultimate battle won’t be. They are learning something that affects the outcome. This behavior is symbolic signaling. These are very simple creatures but their scope of communication is roughly parallel to even very complex mammals like wolves. Chemistry is the powerful, swelling music, and body language (stereotyped display) is the lyrics.”

The Ants, Bert Hölldobler and Edward O. Wilson (pages 219 & 220)

Scent is fundamental because chemistry is fundamental.

“Who trusted God was love indeed
And love, Creation’s final law.
Tho’ Nature, red in tooth and claw
With ravine, shriek’d against his creed.

~ Alfred Lord Tennyson’s In Memoriam A. H. H., 1850.

No human creation grows in isolation from the culture around it or from the deeper rules of our species. Science isn’t exempt from this truth, especially where theories and results cross swords with ideology and vested interest.

Charles Darwin wasn’t a bad guy, he was highly intelligent with a gentle disposition. Nor was he an especially good guy. As restless as his intellect was, he was a creature of his class and his time. He was rich and privileged and utterly convinced of the rightness of this arrangement. In his world, it was a given that the aristocracy earned its good fortune with innate superiority. The poor were a sorry lot who were to be pitied (within reason) for their inadequacy. They lived in squalor and lack due to their flawed nature.

This harsh and rejecting aspect of the human mind toward poverty is becoming well documented. If you haven’t already read it, I suggest you take a quick look at my post Neuromechanical Cruelty. Hating or at least disdaining and disliking the poor appears to be a human norm. Being nice and helpful to the rich, likewise. Those behaviors are the classic homosapien elevation of an “alpha” group deemed superior. These rise to the top of a power pyramid. The large base beneath consists of people smiling at those above and frowning at those below. This is the piece of our nature that automatically creates a rich, protected elite and self sorts the rest into a caste or class system. This is our history everywhere since the late Neolithic. It is an innate part of how human tribes over a certain size, organize themselves. It isn’t imposed from above even though it feels that way.

Anyway, the reason you know about Darwin’s theory of evolution is not because he alone was correct. It is because his version of evolutionary theory supported the pre-existing beliefs of the English aristocracy and because he was one of them. Far from shocking them, he essentially told them they had been right all along.

In terms of public reaction, the publication of Darwin’s theory played several different roles simultaneously.

  1. When many people were beginning to look at life through a non-religious lens and sensing the absurdity of Adam and Eve, it was a practical, possible alternative.
  2. When different ideas about evolution were gaining popularity, it was the one that most supported the status quo, current biases and justified the existence (and power!) of the upper class.
  3. It tacitly deposed Jehova, an invisible omnipresent bloodthirsty god full of hates and jealousies with an observable omnipresent bloodthirsty god for whom it was nothing personal.
  4. It became the insurgent landfall of science in the struggle with religious authority and once established, became ground that must not be surrendered.

The British empire was at the height of its “Imperial Century”, at this time, it included over 14 million square miles of territory and 450 million people. It included more than a quarter of the world’s population and it was said that the sun never set on the British Empire, a phrase attributed to a Scottish writer, John Wilson. It’s not surprising then, that the dominant meme about life among the upper class British at this time was that life was a bloody struggle, that success was evidence of superiority and to the victor go the spoils. Might makes right. You can hardly blame them for thinking so.

With its emphasis on fitness as the key to evolutionary success and competitive pressure as the engine driving it, Darwin’s theory described a bloody struggle, in the end rewarding the best. This is a case of fielding a scientific theory which seems radical on one hand but reassuringly familiar on the other. If you were tasked with deciding between two radical theories, wouldn’t you feel at least an attraction to the one that more confirmed what you already believed? Confirmation bias is a hell of a drug.

Darwin’s competition was Alfred Russel Wallace who was poor, politically progressive, and lower class. Wallace had sent Darwin his own theory in 1858 to see what he thought of it. Darwin was shocked at the similarity to his own work and after YEARS of sitting on it, rushed to publication. When the theory of natural selection was unveiled to the scientific community at the Linnean Society on July 1, 1858, the entire program was engineered by Darwin’s colleagues and close friends, Joseph Hooker and Charles Lyell, to give their friend priority. When Origin was published a little over a year later, modern evolutionary theory became Darwin’s theory.

It’s worth noting that the champions of “Survival of the fittest” cheated to win. This was not the only time that a scientific theory gained prominence through collusion by powerful friends but possibly the most ironic. Of course, it’s possible that Darwinism would have won in a fair fight… but it didn’t. Cronyism made certain it didn’t have to.

In a follow up I’ll talk about:

  • The fascinating redemption in just the last few years of both Wallace and Jean-Baptiste Lamarck. Lamarck was a still earlier evolutionary theorist who has mostly been mentioned in a hundred years of biology textbooks in order to say he was wrong.
  • How “Social Darwinism” grew like a weed in Darwin’s yard.
  • The reason certain weaknesses of the Darwinian theory have lasted far longer than they should have.
  • The reason that the current right wing is ALREADY getting involved in fighting against certain recent discoveries about inheritance. (Hint: they lead to questions about some of the very same biases I mentioned at the beginning of this article).

Humans are born according to an algorithm allowing a wide curve of features and preferences such as:


  1.  Self asserting (extreme archetype: Psychopathic self involvement)   |    Self transcending (extreme archetype: Saintly generosity and sacrifice)
  2. Follow the pack (instinctively flows with peer pressure)   |    Follow my own path (instinctively flows their own way)
  3. Past loving (keep the familiar = “conservative”)    |    Future loving  (allow for change = “progressive”)
  4. Preference for small groups (town)    |    Preference for large groups (city)
  5. Submissive (naturally accept leadership) | Dominant (naturally take charge)
  6. Cautious (“Wouldn’t be prudent”)    |    Daring (risk taking adventurers)
  7. Wandering (Viking approach)   |    Homebound (Bushman approach)
  8. Standard Sexuality    |    Alternate Sexuality 
  9.  Xenophobic   |    Xenophophilic
 There is no pattern or hierarchy in what I’ve listed, merely some of the options.
Wherever people form communities these characteristics will lean this way and that in any given generation. Then a  Darwinian survival of the fittest behavior-styles for that time and place plays out. Naturally certain constellations of these data points are more popular and successful in general, but also specific groups of traits are prized (and thus more successful) in different cultures and different environmental areas with different challenges.
People with the surviving personality data points become the stereotypical “person from…”. But we should be able distinguish the difference between there being SOME reality to a geolocated personality style and simple bigotry. Naturally that generation will have children which trend their way but it’s never as simple as that. Human communities require at least a degree of tension between personality extremes. A group needs to have the adaptability to change gears and directions if opportunity or need arises. There needs to be a healthy homeostasis. Human groups are (pre)programmed to organize themselves to have a society which has a dominant style but includes a range of opinions and styles from fundamentalist hardliners for the local hive story to critical thinking rebels or even revolutionaries.

One reason we can conclude “It takes all kinds” is because life MAKES all kinds.
