This is a little quote from E. O. Wilson’s Sociobiology that I deleted from the previous post for being a little tangential, but it is still interesting
Guppies (Lebistes reticulatus) are well known for the stabilization of their populations in aquaria by the consumption of their excess young.
So that’s what happened to my pet fish! I always wondered why they seemed to appear and disappear at random. It wasn’t a big enough bowl to logically be losing them in.
Um. Poor guppies.
“Cannibalism is commonplace in the social insects, where it serves as a means of conserving nutrients as well as a precise mechanism for regulating colony size. The colonies of all termite species so far investigated promptly eat their own dead and injured. Cannibalism is in fact so pervasive in termites that it can be said to be a way of life in these insects. …
The eating of immature stages is common in the social Hymenoptera.
Hymenoptera is an order of insects with over 150,000 species, including ants and bees. (Termites, despite also being social, are not members of hymenoptera, and are more closely related to cockroaches.)
Among most or all hymenopterans, sex is determined by the number of chromosomes an individual possesses. Fertilized eggs get two sets of chromosomes (one from each parent’s respective gametes) and develop into diploid females, while unfertilized eggs only contain one set (from the mother) and develop into haploid males. The act of fertilization is under the voluntary control of the egg-laying female, giving her control of the sex of her offspring. This phenomenon is called haplodiploidy.
However, the actual genetic mechanisms of haplodiploid sex determination may be more complex than simple chromosome number. In many Hymenoptera, sex is actually determined by a single gene locus with many alleles. In these species, haploids are male and diploids heterozygous at the sex locus are female, but occasionally a diploid will be homozygous at the sex locus and develop as a male, instead. This is especially likely to occur in an individual whose parents were siblings or other close relatives. Diploid males are known to be produced by inbreeding in many ant, bee, and wasp species. Diploid biparental males are usually sterile but a few species that have fertile diploid males are known.
One consequence of haplodiploidy is that females on average actually have more genes in common with their sisters than they do with their own daughters. Because of this, cooperation among kindred females may be unusually advantageous, and has been hypothesized to contribute to the multiple origins of eusociality within this order. In many colonies of bees, ants, and wasps, worker females will remove eggs laid by other workers due to increased relatedness to direct siblings, a phenomenon known as worker policing.
Another consequence is that hymenopterans may be more resistant to the deleterious effects of inbreeding. As males are haploid, any recessive genes will automatically be expressed, exposing them to natural selection. Thus, the genetic load of deleterious genes is purged relatively quickly.
Back to Wilson:
In ant colonies, all injured eggs, larvae, and pupae are quickly consumed. When colonies are starved, workers begin attacking healthy brood as well. In fact, there exists a direct relation between colony hunger and the amount of brood cannibalism that is precise enough to warrant the suggestion that the brood functions normally as a last-ditch food supply to keep the queen and workers alive. In the army ants of the genus Eciton, cannibalism has apparently been further adapted to the purposes of caste determination. According to Schneirla (1971), most of the female larvae in the sexual generation (the generation destined to transform into males and queens) are consumed by workers. The protein is converted into hundred or thousands of males and several of the very large virgin queens. It seems to follow, but is far from proved, that female larvae are determined as queens by this special protein-rich diet. Other groups of ants, bees, and wasps show equally intricate patterns of specialized cannibalism…
Nomadic male lions of the Serengeti plains frequently invade the territories of prids and drive away or kill the resident males. The cubs are also sometimes killed and eaten during territorial disputes. … Infant mortality is much higher as a result of the disturbances [in the social order of langurs.] In the case of P. entellus, [a langur species,] the young are actually murdered by the usurper…
The main character of the first 4 chapters of Harry Potter isn’t Harry: it’s the Dursleys:
Mr and Mrs Dursley, of number four, Privet Drive, were proud to say that they were perfectly normal, thank you very much. They were the last people you’d expect to be involved in anything strange or mysterious, because they just didn’t hold with such nonsense.
The Dursleys are awful and abusive in an over-the-top, Roald Dahl way that somehow manages not to cause Harry any serious emotional problems, which even I, a hard-core hereditarian, would find improbable if Harry were a real boy. But Harry isn’t the point: watching the Dursleys get their comeuppance is the point.
JRR Tolkien and JK Rowling both focused on the same group of people–common English peasants–but Tolkien’s depiction of the Hobbits are much more sympathetic than Rowling’s Muggles, even if they don’t like adventures:
This hobbit was a very well-to-do hobbit, and his name was Baggins. The Bagginses had lived in the neighborhood of The Hill for time out of mind and people considered them very respectable, not only because most of them were rich, but also because they never had any adventures or did anything unexpected: you could tell what a Baggins would say on any question without the bother of asking him.
We could wax philosophical (or political) about why Tolkien sees common folk as essentially good, despite their provinciality, and why Rowling sees them as essentially bad, for precisely the same reasons, but in the end both writers are correct, for there is good and bad in all groups.
Why are the Dursleys effective villains? Why is their buffoonish abuse believable, and why do so many people identify with young Harry? Is he not the Dursley’s kin, if not their son, their nephew? Shouldn’t they look out for him?
One of the great ironies of life is that the people who are closest to us are also the most likely to abuse us. Despite fears of “stranger danger” (or perhaps because of it) children are most likely to be harmed by parents, step-parents, guardians, or other close relatives/friends of the family, not strangers lurking in alleys or internet chatrooms.
…there were an estimated 57 000 deaths attributed to homicide among children under 15 years of age in 2000. Global estimates of child homicide suggest that infants and very young children are at greatest risk, with rates for the 0–4-year-old age group more than double those of 5–14-year-olds…
The risk of fatal abuse for children varies according to the income level of a country and region of the world. For children under 5 years of age living in high-income countries, the rate of homicide is 2.2 per 100 000 for boys and 1.8 per 100 000 for girls. In low- to middle-income countries the rates are 2–3 times higher – 6.1 per 100 000 for boys and 5.1 per 100 000 for girls. The highest homicide rates for children under 5 years of age are found in the WHO African Region – 17.9 per 100 000 for boys and 12.7 per 100 000 for girls.
(Aside: in every single region, baby boys were more likely to be murdered than baby girls–how’s that “male privilege” for you?)
Estimates of physical abuse of children derived from population-based surveys vary considerably. A 1995 survey in the United States asked parents how they disciplined their children (12). An estimated rate of physical abuse of 49 per 1000 children was obtained from this survey when the following behaviours were included: hitting the child with an object, other than on the buttocks; kicking the child; beating the child; and threatening the child with a knife or gun. …
.In a cross-sectional survey of children in Egypt, 37% reported being beaten or tied up by their parents and 26% reported physical injuries such as fractures, loss of consciousness or permanent disability as a result of being beaten or tied up (17).
. In a recent study in the Republic of Korea, parents were questioned about their behaviour towards their children. Two-thirds of the parents reported whipping their children and 45% confirmed that they had hit, kicked or beaten them (26).
. A survey of households in Romania found that 4.6% of children reported suffering severe and frequent physical abuse, including being hit with an object, being burned or being deprived of food. Nearly half of Romanian parents admitted to beating their children ‘‘regularly’’ and 16% to beating their children with objects (34).
. In Ethiopia, 21% of urban schoolchildren and 64% of rural schoolchildren reported bruises or swellings on their bodies resulting from parental punishment (14).
Ugh. The Dursleys are looking almost decent right now.
In most ways, the Dursleys do not fit the pattern characteristic of most abuse cases–severe abuse and neglect are concentrated among drug-addicted single mothers with more children than they can feed and an unstable rotation of unrelated men in and out of the household. The Dursley’s case is far more mild, but we may still ask: why would anyone mistreat their kin? Wouldn’t natural selection–selfish genes and all that–select against such behavior?
There are a number of facile explanations for the Dursley’s behavior. The first, suggest obliquely by Rowling, is that Mrs. Dursley was jealous of her sister, Lily, Harry’s mother, for being more talented (and prettier) than she was. This is the old “they’re only bullying you because they’re jealous” canard, and it’s usually wrong. We may discard this explanation immediately, as it is simply too big a leap from “I was jealous of my sister” to “therefore I abused her orphaned child for 11 years.” Most of us endured some form of childhood hardship–including sibling rivalry–without turning into abusive assholes who lock little kids in cupboards.
The superior explanation is that there is something about Harry that they just can’t stand. He’s not like them. This is expressed in Harry’s appearance–the Dursleys are described as tall, fat, pink skinned, and blue eyed with straight, blond hair, while Harry is described as short, skinny, pale skinned, and green-eyed with wavy, dark hair.
More importantly, Harry can do magic. The Dursley’s can’t.
It’s never explained in the books why some people can do magic and not others, but the trait looks strongly like a genetic one–not much more complicated than blue eyes. Magic users normally give birth to magical children, and non-magic users (the term “muggle” is an ethnic slur and should be treated as such,) normally have non-magical children. Occasionally magical children are born to regular families, just as occasionally two brown-eyed parents have a blue-eyed child because both parents carried a recessive blue eyed gene that they both happened to pass on to their offspring, and occasionally magical parents have regular children, just as smart people sometimes have dumb offspring. On the whole, however, magical ability is stable enough across generations that there are whole magical families that have been around for hundreds of years and non-magical families that have done the same.
Any other factor–environmental, magical–could have been figured out by now and used to turn kids like Neville into competent wizards, so we conclude that such a factor does not exist.
Magic is a tricky thing to map, metaphorically, onto everyday existence, because nothing like it really exists in our world. We can vaguely imagine that Elsa hiding her ice powers is kind of like a gay person hiding the fact that they are gay, but being gay doesn’t let you build palaces or create sentient snowmen. Likewise, the Dursely’s anger at Harry being “one of them” and adamantly claiming that magic and wizardry don’t exist, despite the fact that they know very well that Mrs. Dursley’s sister could turn teacups into frogs, does resemble the habit of certain very conservative people to pretend that homosexuality doesn’t exist, or that if their children never hear that homosexuality exists, they’ll never become gay.
The other difficulty with this metaphor is that gay people, left to their own devices, don’t produce children.
But putting together these two factors, we arrive at the conclusion that wizards are a distinct, mostly endogamous ethnic group that the Dursleys react to as though they were flaming homosexuals.
How many generations of endogamy would it take to produce two genetically distinct populations from one? Not many–take, for example, the Irish Travellers:
Researchers led by the Royal College of Surgeons in Ireland (RCSI) and the University of Edinburgh analysed genetic information from 42 people who identified as Irish Travellers.
The team compared variations in their DNA code with that of 143 European Roma, 2,232 settled Irish, 2,039 British and 6,255 European or worldwide individuals. …
They found that Travellers are of Irish ancestral origin but have significant differences in their genetic make-up compared with the settled community.
These differences have arisen because of hundreds of years of isolation combined with a decreasing Traveller population, the researchers say. …
The team estimates the group began to separate from the settled population at least 360 years ago.
That’s a fair bit of separation for a mere 360 years or so–and certainly enough for your relatives to act rather funny about it if you decided to run off with Travellers and then your orphaned child turned up on their doorstep.
How old are the wizarding families? Ollivander’s Fine Wands has been in business since 382 BC, and Merlin, Agrippa, and Ptolemy are mentioned as ancient Wizards, so we can probably assume a good 2,000 years of split between the two groups, with perhaps a 10% in-migration of non-magical spouses.
Harry is, based on his parents, 50% magical and 50% non-magical, though of course both Lily and Petunia Dursley probably carry some Wizard DNA.
In The Blank Slate, Pinker has some interesting observations on the subject of sociobiology:
As the notoriety of Sociobiology grew in the ensuing years, Hamilton and Trivers, who had thought up many of the ideas, also became targets of picketers… Trivers had argued that sociobiology is, if anything a force for political progress. It is rooted in the insight that organisms did not evolve to benefit their family, group, or species, because the individuals making up those groups have genetic conflicts of interest with one another and would be selected to defend those interests. This immediately subverts the comfortable belief that those in power rule for the good of all, and it throws a spotlight on hidden actors in the social world, such as female sand the younger generation.
Further in the book, Pinker continues:
Tolstoy’s famous remark that happy families are all alike but every unhappy family is unhappy in its own way is not true at the level of ultimate (evolutionary) causation. Trivers showed how the seeds of unhappiness in every family have the same underlying source. Though relatives have common interests because of their common genes, the degree of overlap is not identical within all their permutations and combinations of family members. Parents are related to all of their offspring by an equal factor, 50 percent, but each child is related to himself or herself by a factor of 100 percent. …
Parental investment is a limited resource. A day has only twenty-four hours … At one end of the lifespan, children learnt hat a mother cannot pump out an unlimited stream of milk; at the other, they learn that parents do not leave behind infinite inheritances.
To the extent that emotions among people reflect their typical genetic relatedness, Trivers argued, the members of a family should disagree on how parental investment should be divvied up.
And to the extent that one of the children in a household is actually a mixed-ethnicity nephew and no close kin at all to the father, the genetic relationship is even more distant between Harry and the Dursleys than between most children and the people raising them.
Parents should want to split their investment equitably among the children… But each child should want the parent to dole out twice as much of the investment to himself or herself as to a sibling, because children share half their genes with each full sibling but share all their genes with themselves. Given a family with two children and one pie, each child should want to split it in a ratio of two thirds to one third, while parents should want it to be split fifty fifty.
A person normally shares about 50% of their genes with their child and 25% of their genes with a niece or nephew, but we also share a certain amount of genes just by being distantly related to each other in the same species, race, or ethnic group.
Harry is, then, somewhat less genetically similar than the average nephew, so we can expect Mrs. Dursley to split any pies a bit less than 2/3s for Dudley and 1/3 for Harry, with Mr. Dursley grumbling that Harry doesn’t deserve any pie at all because he’s not their kid. (In a more extreme environment, if the Dursleys didn’t have enough pie to go around, it would be in their interest to give all of the pie to Dudley, but the Dursleys have plenty of food and they can afford to grudgingly keep Harry alive.)
Most kinds of social behavior, including perhaps all of the most complex forms, are based in one way or another on kinship. As a rule, the closer the genetic relationship of the members of a group, the more stable and intricate the social bonds of its members. …
Parent-offspring conflict and its obverse, sibling-sibling conflict, can be seen throughout the animal kingdom. Littermates or nestmates fight among themselves sometimes lethally, and fight with their mothers over access to milk, food, and care…. The conflict also plays out in the physiology of prenatal human development. Fetuses tap their mothers’ bloodstreams to mine the most nutrients possible from their body, while the mother’s body resists to keep it in good shape for future children. …
Trivers touted the liberatory nature of sociobiology by invoking an “underlying symmetry in our social relationships” and “submerged actors in the social world.” He was referring to women, as we will see in the chapter on gender, and to children. The theory of parent-offspring conflict says that families do not contain all-powerful, all-knowing parents and their passive, grateful children. …
Sometimes families contain Dursleys and Potters.
Most profoundly, children do not allow their personalities to be shaped by their parents’ nagging, blandishments, or attempts to serve as role models.
Quite lucky for Harry!
The offspring cannot rely on its parents for disinterested guidance. One expects the offspring to be preprogrammed to resist some parental manipulation while being open to other forms. When the parent imposes an arbitrary system of reinforcement (punishment and reward) in order to manipulate the offspring to act against its own best interests, selection will favor offspring that resist such schedules of reinforcement.
(Are mixed-race kids more likely to be abused than single-race kids? Well, they’re more likely to be abused than White, Asian, or Hispanic kids, but less likely to be abused than Black or Native American children [Native American children have the highest rates of abuse]. It seems likely that the important factor here isn’t degree of relatedness, but how many of your parents hail from a group with high rates of child abuse. The Dursleys are not from a group with high child abuse rates.)
Let us return to E. O. Wilson’s Sociobiology:
Mammalogists have commonly dealt with conflict as if it were a nonadaptive consequence of the rupture of the parent-offspring bond. Or, in the case of macaques, it has been interpreted as a mechanism by which the female forces the offspring into independence, a step designed ultimately to benefit both generations. …
A wholly different approach to the subject has been taken by Trivers (1974). … Trivers interprets it as the outcome of natural selection operating in opposite directions on the two generations. How is it possible for a mother and her child to be in conflict and both remain adaptive? We must remember that the two share only one half their genes by common descent. There comes a time when it is more profitable for the mother to send the older juvenile on its way and to devote her efforts exclusively to the production of a new one. To the extent that the first offspring stands a chance to achieve an independent life, the mother is likely to increase (and at most, double,) her genetic representation in the next breeding generation by such an act. But the youngster cannot be expected to view the matter in this way at all. …
If the mothers inclusive fitness suffers first from the relationship, conflict will ensue.
At some point, of course, the child is grown and therefore no longer benefits from the mother’s care; at this point the child and mother are no longer in conflict, but the roles may reverse as the parents become the ones in need of care.
As for humans:
Consider the offspring that behaves altruistically toward a full sibling. If it were the only active agent, its behavior would be selected when the benefit to the sibling exceeds two times the cost to itself. From the mother’s point of view, however, inclusive fitness is gained however the benefit to the sibling simply exceeds the cost to the altruist. Consequently, there is likely to evolve a conflict between parents and offspring in the attitudes toward siblings: the parent will encourge more altruism than the youngster is prepared to give. The converse argument also holds: the parent will tolerate less selfishness and spite among siblings than they have a tendency to display…
Indeed, Dudley is, in his way, crueler (more likely to punch Harry) and more greedy than even his parents.
Altruistic acts toward a first cousin are ordinarily selected if the benefit to the cousin exceeds 8 times the cost to the altruist, since the coefficient of relationship of first cousins is 1/8. However, the parent is related to its nieces and nephews by r=1/4, and it should prefer to see altruistic acts by its children toward their cousins whenever the benefit-to-cost ratio exceeds 2. Parental conscientiousness will also extend to interactions with unrelated individuals. From a child’s point of view, an act of selfishness or spite can provide a gain so long as its own inclusive fitness is enhanced… In human terms, the asymmetries in relationship and the differences in responses they imply will lead in evolution to an array of conflicts between parents and their children. In general, offspring will try to push their own socialization in a more egoistic fashion, while the parents will repeatedly attempt to discipline the children back to a higher level of altruism. There is a limit to the amount of altruism [healthy, normal] parents want to see; the difference is in the levels that selection causes the two generations to view as optimum.
To return to Pinker:
As if the bed weren’t crowded enough, every child of a man and a woman is also the grandchild of two other men and two other women. Parents take an interest in their children’s reproduction because in the long run it is their reproduction, too. Worse, the preciousness of female reproductive capacity makes it a valuable resource for the men who control her in traditional patriarchal societies, namely her father and brothers. They can trade a daughter or sister for additional wives or resources for themselves and thus they have an interest in protecting their investment by keeping her from becoming pregnant by men other than the ones they want to sell her to. It is not just the husband or boyfriend who takes a proprietary interest in a woman’s sexual activity, then, but also her father and brothers. Westerners were horrified by the treatment of women under the regime of the Taliban in Afghanistan from 1995 to 2001…
[ah such an optimist time Pinker wrote in]
Like many children, Harry is rescued from a bad family situation by that most modern institution, the boarding school.
The weakening of parents’ hold over their older children is also not just a recent casualty of destructive forces. It is part of a long-running expansion of freedom in the West that has granted children their always-present desire for more autonomy than parents are willing to cede. In traditional societies, children were shackled to the family’s land, betrothed in arranged marriages, and under the thumb of the family patriarch. That began to change in Medieval Europe, and some historians argue it was the first steppingstone in the expansion of rights that we associate with the Enlightenment and that culminated in the abolition of feudalism and slavery. Today it is no doubt true that some children are led astray by a bad crowd or popular culture. But some children are rescued from abusive or manipulative families by peers, neighbors, and teachers. Many children have profited from laws, such as compulsory schooling and the ban on forced marriages, that may override the preferences of their parents.
The sad truth, for Harry–and many others–is that their interests and their relatives’ interests are not always the same. Sometimes humans are greedy, self-centered, or just plain evil. Small children are completely dependent on their parents and other adults, unable to fend for themselves–so the death of his parents followed by abuse and neglect by his aunt and uncle constitute true betrayal.
But there is hope, even for an abused kid like Harry, because we live in a society that is much larger than families or tribal groups. We live in a place where honor killings aren’t common and even kids who aren’t useful to their families can find a way to be useful in the greater society. We live in a civilization.
In The Blank Slate, Steven Pinker gives about the best recommendation I can think of for Wilson’s book:
At Harvard there were leaflets and teach-ins, a protester with a bullhorn calling for Wilson’s dismissal, and invasions of his classroom by slogan-shouting students. When he spoke at other universities, posters called him the “Right-Wing-Prophet of Patriarchy” and urged people to bring noisemakers to his lectures. Wilson was about to speak at a 1978 meeting of the American Association for the Advancement of Science when a group of people carrying placards (one with a swastika) rushed onto the stage chanting, “Racist Wilson, you can’t hide, we charge you with genocide.” One protester grabbed the microphone and harangued the audience while another doused Wilson with a pitcher of water.
Pretty intense for a guy whose career is mostly about ants.
Since it is easier to remember what you have read if you take notes and then transcribe them, and this thing is 574 pages long, I’ll be transcribing some of my notes here as I go along.
The book gives lots of interesting examples of different concepts. For example, in the section on parasitism, there’s an example of a variety of termite that moves into and eats the nests of other termites, thus making a termite mound-in-a-mound, I suppose. To be fair, some termite mounds are about as big as a house and so this is a totally reasonable thing for termites to do.
Chapter 1: The morality of the Gene
Camus said that the only serious philosophical question is suicide.
That is wrong even in the strict sense intended. …
From now on, let’s use “” instead of blockquotes.
Chapter 2: Elementary Concepts
“Genes, like Leibnitz’s monads, have no windows; the higher properties of life are emergent. To specify an entire cell, we are compelled to provide not only the nucleotide sequences but also the identity and configuration of other kinds of molecules placed in and around the cells. To specify an organism requires still more information about both the properties of the cells and their spacial positions. And once assembled, organisms have no windows. A society can be described only as a set of particular organisms, and even then it is difficult to extrapolate the joint activity of this ensemble from the instant of specification, that is, to predict social behavior. …
“Society: a group of individuals belonging to the same species and organized in a cooperative manner. … Yet aggregation, sexual behavior, and territoriality are important properties of true societies, and they are correctly referred to as social behavior. … Since the bond of the society is simply and solely communication, its boundaries can be defined in terms of the curtailment of communication.”
EvX: I have been thinking for a long time about language as effective barriers of culture. Not that culture can’t cross language barriers (movies get dubbed all the time,) but it’s much harder. And since some languages are easier to learn than others, (eg, Finnish is harder than German if you speak English,) cross-language communication is probably easier between some groups than others. The Finns (and a few other European groups) speak non-Indo-European languages, which might make them more functionally isolated within the European context than, say, their neighbors in Sweden.
Back to Wilson:
“Individual: Any physically distinct organism… The distinction between the individual and the colony can be especially baffling in the sponges. … [Hah.]
“Population: A set of organisms belonging to the same species and occupying a clearly delimited area at the same time. This unit… is defined in terms of genetic continuity. In the case of sexually reproducing organisms, the population is a geographically delimited set of organisms capable of freely interbreeding with one another under natural conditions. …
“In sexually reproducing forms, including the vast majority of social organisms, a species is a population or set of populations within which the individuals are capable of freely interbreeding under natural conditions. By definition the members of the species do not interbreed freely with those of other species, however closely related they may be genetically. … In establishing the limits of a species it is not enough merely to prove that genes of two or more populations can be exchanged under experimental conditions. The population must be demonstrated to interbreed fully in the free state.”
[Example: Lions and Tigers can interbreed, yet even in places where their ranges historically overlapped, no one ever reported finding wild ligers or tigons. While they can interbreed in zoos, their behavior is different enough in the wild that it doesn’t happen.]
EvX: And here’s where people ask about Sapiens and Neanderthals. Yes, they interbred. But it looks like they didn’t interbreed much (while they bred plenty with their own,) and it also looks like there’s been a fair amount of selection against Neanderthal DNA in modern humans, winnowing down the genes passed on to us. For example, there’s pretty much no Neanderthal DNA on the Y chromosome, suggesting that any sons of Neanderthal-Sapiens unions were infertile (or didn’t make it at all.) There’s also no (known) Neanderthal mtDNA, suggesting that the matings that did happen involved Neanderthal men with Sapiens women–or if the opposite pairing happened, those children were brought into Neanderthal tribes. At any rate, the pattern is far from complete interfertility.
Back to Wilson:
“A population that differs significantly from other populations belonging to the same species is referred to as a geographic race or subspecies. Subspecies are separated from other subspecies by distance and geographic barriers that prevent the exchange of individuals, as opposed to the genetically based “intrinsic isolating mechanisms” that hold species apart. Subspecies, insofar as they can be distinguished with any objectivity at all, show every conceivable degree of differentiation from other subspecies. At one extreme are the populations that fall along a cline–a simple gradient in the geographic variation of a given character. In other words, a character that varies in a clinal pattern is one that changes gradually over a substantial portion of the entire range of the species. At the other extreme are subspecies consisting of easily distinguished populations that are differentiated from one another by numerous genetic traits and exchange genes across a narrow zone of intergradation.
The main obstacle in dealing with the population as a unit… is the practical difficulty of deciding the limits of particular populations.”
EvX: I would like to point out that humans made up these words to carve up a part of reality that doesn’t always carve that easily. For example, it may be obvious that a wolf species that ranges over thousands of miles is pretty different at the far east and far western extent of its range, but there may be no exact spot in between where the eastern type ends and the western type begins. By contrast, sometimes in human societies you have groups of genetically and culturally distinct people separated for centuries by little more than a road, a wall, a religion, or a language. There is no a priori reason to think that one of these cases fits the definition and the other does not.
But the language we use to delineate groups of ants or wolves or fungi is not the language we use to delineate humans, not just because we wish to be inaccurate, but also because we generally wish to show each other respect. We do so by avoiding language normally reserved for non-humans and using special terms for humans, eg, my offspring are normally referred to as my “children.”
Back to Wilson.
“What is the relation between the population and the society? Here we arrive unexpectedly at the crux of theoretical sociobiology. The distinction between the two categories is essentially as follows: the population is bounded by a zone of sharply reduced gene flow, while the society is bounded by a zone of sharply reduced communication. Often the two zones are the same…
The Multiplier Effect
“Social organization is the class of phenotypes furthest removed from the genes. It is derived jointly from the behavior of the individuals and the demographic properties of the population… A small evolutionary change in the behavior pattern of individuals can be amplified into a major social effect by the expanding upward distribution of the effect into multiple facets of life. …
“Even stronger multiplier effects occur in the social insects. … The structure of nests alone can be used to distinguish species within the higher termites.”
EvX: There follows an interesting description of how termites build their mounds, also known as “termitaries.”
“Multiplier effects can speed social evolution still more when an individual’s behavior is strongly influenced by the particularities of its social experience. This process, called socialization, becomes increasingly becomes increasingly prominent as one moves upward phylogenetically into more intelligent species, and it reaches its maximum influence in the higher primates. Although the evidence is still largely inferential, socialization appears to amplify phenotypic differences among primate species. …
S”ocialization can also amplify genetically based variation of individual behavior within troops. The temperament and rank of a higher primate is strongly influenced by its early experiences with its peers and its mother.”
EvX: This is a really interesting idea. We hear constantly that ideas like race and gender are social constructs, but what exactly a social construct is we hear far less often. The implication–at least as the phrases are employed–is that they are not real at all, that they are make believe, that we have chosen some random and arbitrary place to carve up reality and that we could use some other random place just as well, but Wilson provides a much better conception: “social constructs” are really amplified ideas about the world around us. In other words, they’re exaggerated stereotypes.
For example, let’s imagine a world in which the average male is taller than the average female, but there’s a lot of variety in height and so there are many individual men who are shorter than a good chunk of women, and likewise many women who are taller than a decent chunk of men. The idea that “men are taller than women” is of course true on average, but also an exaggeration. Men who are particularly short and women who are particularly tall may dislike the fact that they don’t match this Platonic ideal.
Back to Wilson:
“The Evolutionary Pacemaker and Social Drift
“…when evolution involves both structure and behavior, behavior should change first and then structure. In other words, behavior should be the evolutionary pacemaker. … Social behavior also frequently serves as an evolutionary pacemaker. The entire process of ritualization, during which a behavior is transformed by evolution into a more efficient signaling device, typically involves a behavioral change followed by morphological alterations that enhance the visibility and distinctiveness of the behavior.
“The relative lability of behavior leads inevitably to social drift, the random divergence in the behavior and mode of organization of societies or groups of societies. …
“The amount of variance within a population of societies is the sum of the variations due to genetic drift, tradition drift, and their interaction. … Even if the alteration to social structure of a group is due to a behavioral change in a key individual, we cannot be sure that this member was not predisposed to the act by a distinctive capability or temperament conferred by a particular set of genes …
“…Cavalli-Sforza and Feldman (1973) have suggested that in human social evolution the equivalent of an important mutation is a new idea. If it is acceptable and advantageous, the idea will spread quickly. If not, it will decline in frequency and he forgotten. Tradition drift in such instances, like purely genetic drift, has stochastic properties amenable to mathematical analysis.”
EvX: Good old memes. How I love them.
“All true societies are differentiated populations. When cooperative behavior evolves it is put to service by one kind of individual on behalf of another, either unilaterally or mutually…
“The proportions of the demographic classes [like old and young people] also affect the fitness of the group and, ultimately, of each individual member… a deviant population allowed to reproduce for one to several generations will go far to restore the age distribution of populations normal for the species.”
EvX: By “deviant population” he means a population that has more or less of a particular class than is ideal, like if an ant colony lost half of its workers in an accident or a plague wiped out most of the children in a society.
“Only if its growth is zero when averaged over many generations can the population have a chance of long life. There is one remaining way to be a success. A population headed for extinction can still possess a high degree of fitness if it succeeds in sending out propagules and creates new populations elsewhere.”
Greetings! Grab a cup of coffee and pull up a chair. Tea is also good. Today we’re diving into chapter one of Philip Auerswald’s The Code Economy, “Jobs: Divide and Coordinate.”
I wish this chapter had been much longer; we speed through almost 2.5 million years of cognitive evolution in a couple of pages.
The earliest hominins had about the same short-term memory as a modern-day chimpanzee, which is to say they could keep track of only two operations at a time. … Our methods for creating tools gradually became more sophisticated, until we were using the tools we created to produce other tools in a repetitive and predictable manner. These processes for creating stone tools were among humanity’s first production algorithms-that is, the earliest code. They appeared almost simultaneously in human communities in most part of the world around 40,000 BC.
…[E.O.] Wilson refers to this phenomenon more broadly as the discovery of eusocial behavior… Wilson situates the date far earlier in human history than I do here. I chose 50,000 years [ago] because my focus is on the economy. it is clear that an epochal change in society occurred roughly 10,000 years BCE, when humans invented agriculture in six parts of the world simultaneously. The fact of this simultaneity directly suggests the advance of code represented by the invention of agriculture was part of a forward movement of code that started much earlier.
What do you think? Does the simultaneous advent of behavioral modernity–or eusociality–in far-flung human groups roughly 50,000 years ago, followed by the simultaneous advent of agriculture in several far-flung groups about 10,000 years ago speak to the existence of some universal, underlying process? Why did so many different groups of people develop similar patterns of life and technology around the same time, despite some of them being highly isolated? Was society simply inevitable?
The caption on the photo is similarly interesting:
Demand on Short-Term Working Memory in the Production of an Obsidian Axe [from Read and van der Leeuw, 2015] … We can relate the concepts invoked in the prodcution of stone tools to the number of dimensions involved and thereby to the size of short-term workign memory (STWM) required for the prodction of the kind of stone tools that exemplify each stage in hominin evolution. …
Just hitting the end of a pebble once to create one edge, as in the simplest tools, they calculate requires holding three items in the working memory. Removing several flakes to create a longer edge (a line), takes STWM 4; working an entire side takes STWM 5; and working both sides of the stone in preparation for knapping flakes from the third requires both an ability to think about the pebble’s shape in three dimensions and STWM 7.
(The Wikipedia article on Lithic Reduction has a lovely animation of the technique.)
It took about 2 million years to proceed from the simplest tools (working memory: 3) to the most complex (working memory: 7.) Since the Neolithic, our working memory hasn’t improved–most of us are still limited to a mere 7 items in our working memory, just enough to remember a phone number if you already know the area code.
All of our advances since the Neolithic, Auerswald argues, haven’t been due to an increase in STWM, but our ability to build complexity externally: through code. And it was this invention of code that really made society take off.
By about 10,000 BCE, humans had formed the first villages… Villages were the precursors of modern-day business firms in that they were durable association built around routines. … the advance of code at the village level through the creation of new technological combinations set into motion the evolution from simplicity to complexity that has resulted in the modern economy.
It was in the village, then, that code began to evolve.
What do you think? Are Read and van der Leeuw just retroactively fitting numbers 3-7 to the tools, or do they really show an advance in working memory? Is the village really the source of most code evolution? And who do you think is more correct, Herbert Spencer or Thomas Malthus?
Auerswald then forward to 1557, with the first use of the word “job” (spelled “jobbe,” most likely from “gobbe,” or lump.)
The advent of the “jobbe” a a lump of work was to the evolution of modern society something like what the first single-celled organism was to the evolution of life.
The “jobbe” contrasted with the obligation to perform labor continuously and without clearly defined roles–slavery, serfdom, indentured servitude, or even apprenticeship–as had been the norm throughout human history.
Did the Black Death help create the modern “job market” by inspiring Parliament to pass the Statute of Laborers?
I am reminded here of a passage from Gulick’s Evolution of the Japanese, Social and Psychic, (published in 1903):
The idea of making a bargain when two persons entered upon some particular piece of work, the one as employer, the other as employed, was entirely repugnant to the older generation, since it was assumed that their relations as inferior and superior should determine their financial relations; the superior would do what was right, and the inferior should accept what the superior might give without a question or a murmur. Among the samurai, where the arrangement is between equals, bargaining or making fixed and fast terms which will hold to the end, and which may be carried to the courts in case of differences, was a thing practically unknown in the older civilization. Everything of a business nature was left to honor, and was carried on in mutual confidence.
“A few illustrations of this spirit of confidence from my own experience may not be without interest. On first coming to Japan, I found it usual for a Japanese who wished to take a jinrikisha to call the runner and take the ride without making any bargain, giving him at the end what seemed right. And the men generally accepted the payment without question. I have found that recently, unless there is some definite understanding arrived at before the ride, there is apt to be some disagreement, the runner presuming on the hold he has, by virtue of work done, to get more than is customary. This is especially true in case the rider is a foreigner. Another set of examples in which astonishing simplicity and confidence were manifested was in the employment of evangelists. I have known several instances in which a full correspondence with an evangelist with regard to his employment was carried on, and the settlement finally concluded, and the man set to work without a word said about money matters. It need hardly be said that no foreigner took part in that correspondence. …
“This confidence and trustfulness were the product of a civilization resting on communalistic feudalism; the people were kept as children in dependence on their feudal lord; they had to accept what he said and did; they were accustomed to that order of things from the beginning and had no other thought; on the whole too, without doubt, they received regular and kindly treatment. Furthermore, there was no redress for the peasant in case of harshness; it was always the wise policy, therefore, for him to accept whatever was given without even the appearance of dissatisfaction. This spirit was connected with the dominance of the military class. Simple trustfulness was, therefore, chiefly that of the non-military classes. …
“Since the overthrow of communal feudalism and the establishment of an individualistic social order, necessitating personal ownership of property, and the universal use of money, trustful confidence is rapidly passing away.
We still identify ourselves with our profession–“I am a doctor” or “I am a paleontologist”–but much less so than in the days when “Smith” wasn’t a name.
Auerswald progresses to the modern day:
In the past two hundred years, the complexity of human economic organization has increased by orders of magnitude. Death rates began to fall rapidly in the middle of the nineteenth century, due to a combination of increased agricultural output, improved hygiene, and the beginning of better medical practices–all different dimensions of the advance of code…. Greater numbers of people living in greater density than ever before accelerated the advance of code.
Sounds great, but:
By the twentieth century, the continued advance of code necessitated the creation of government bureaucracies and large corporations that employed vast numbers of people. These organizations executed code of sufficient complexity that it was beyond the capacity of any single individual to master.
I’ve often wondered if the explosion of communist disasters at the beginning of the 20th century occurred because we could imagine a kind of nation-wide code for production and consumption and we had the power to implement it, but we didn’t actually have the capabilities and tools necessary to make it work.
We can imagine Utopia, but we cannot reach it.
Auerswald delineates two broad categories of “epochal change” as a result of the code-explosion of the past two centuries: First, our capabilities grew. Second:
“we have, to an increasing degree, ceded to other people–and to code itself–authority and autonomy, which for millennia we had kept unto ourselves and our immediate tribal groups as uncodified cultural norms.”
Before the “job”, before even the “trade,” people lived and worked far more at their own discretion. Hoeing fields or gathering yams might be long and tedious work, but at least you didn’t have to pee in a bottle because Amazon didn’t give you time for bathroom breaks.
Every time voters demand that politicians “bring back the jobs” or politicians promise to create them, we are implicitly stating that the vast majority of people are no longer capable of making their own jobs. (At least, not jobs that afford a modern lifestyle.) The Appalachians lived in utter poverty (the vast majority of people before 1900 lived in what we would now call utter poverty), but they did not depend on anyone else to create “jobs” for them; they cleared their own land, planted their own corn, hunted their own hogs, and provided for their own needs.
Today’s humans are (probably not less intelligent nor innately capable than the average Appalachian of 1900, but the economy (and our standards of living) are much more complex. The average person no longer has the capacity to drive job growth in such a complicated system, but the solution isn’t necessarily for everyone to become smarter. After all, large, complicated organizations need hundreds of employees who are not out founding their own companies.
But this, in turn, means all of those employees–and even the companies themselves–are dependent on forces far outside their control, like Chinese monetary policy or the American electoral cycle. And this, in turn, raises demand for some kind of centralized, planned system to protect the workers from economic hardship and ensure that everyone enjoys a minimum standard of living.
Microstates suggest themselves as a way to speed the evolution of economic code by increasing the total number of organisms in the ecosystem.
With eusociality, man already became a political (that is, polis) animal around 10,000 or 40,000 or perhaps 100,000 years ago, largely unable to subsist on his own, absent the tribe. We do not seem to regret this ill-remembered transition very much, but what about the current one? Is the job-man somehow less human, less complete than the tradesman? Do we feel that something essential to the human spirit has been lost in defining and routinizing our daily tasks down to the minute, forcing men to bend to the timetables of factories and international corporations? Or have we, through the benefits of civilization (mostly health improvements) gained something far richer?
