Ideology, evolution and the culture-wars

Mark Kleiman says:

Most of my friends…the blue team…are genuinely puzzled by the anti-evolution fury evident among elements of the red team….

To which I say, I am genuinely puzzled by the anti-genetic fury often in evidence among elements of the blue team. Just because we are animals doesn’t imply we should behave like other animals, and just because we have behavioral biases rooted in our genetic heritage doesn’t mean we should valorize our biases as necessary for the Good Life. I agree with Lindsay Beyerstein, we shouldn’t “play along with those delusions because” we preceive that the ends are just or proper. We should attempt to find a way to attain the Good Life and live by Truth.

Addendum: William Jennings Bryan’s concern that evolutionary accounts of human ancestry from animals dovetailed too well with Social Darwinist attempts to control and oppress the “lower orders” merges the two cautionary impulses.

Also, Mark says:

The account in Genesis, whether believed literally or accepted as a morally relevant metaphor, provides a very direct and convincing argument in favor of universal human rights….

Uh, when was the last time Mark read Genesis?

Super-size this!

Here is the explanation of Judaism and Islam in the “devout Christian spends a month as a Muslim” episode of “30 Days”.Jews believe in the existence of one true God and are still waiting for his son, the Messiah, to save them.

[Muslims] base their religions on the writings of a later prophet, MuhammadLet’s start with the fact that this was a voiceover during an animated segment, in contradiction to the prohibition on figurative art that both Judaism and Islam share.

1. Judaism does not identify the Messiah as “God’s son”.
2. Referring to the Qur’an as the “writings” of Muhammad is technically incorrect because, according to Muslim tradition, Muhammad was illiterate, like most people of his time and setting. Moreover, the cartoon depicted him leafing through a book.

Developmental stability, symmetry and heterozygosity

Specific questions regarding general rules in organismic biology can sometimes be rather tricky to answer…because of variation between taxa and environmental context there are usually exceptions. A visitor to this website had a few questions regarding asymmetry and heterozygosity, and I responded that the relationship between the two (generally assumed to be a negative one, that is, heterozygosity tends to correlate with less asymmetry) is one where the latter influences the buffering of the developmental arc which leads to bilateral symmetry. When you see lists of traits with heritabilities bilateral symmetry tends to show a low heritability. The reason is that it is usually considered a genetic trait, there is strong selection against any mutations which would result in asymmetries because such a phenotype is not very fit. That being said, perfect symmetry is not achieved because there are other factors which affect the developmental arc of an organism, whether they be environmental or genetic. I offered that the relationship between heterozygosity and lower fluctuating asymmetry results from the more robust immune systems of heterozygous individuals. The logic is that infection tends to interfere with optimal development. Obviously this logic is most relevant in the case of organisms with adaptive immune systems, so I’m not going to point to flie studies. Here is an on point quote from (page 221, use the “search inside” feature on Amazon):

The clear relationships between parasitism and disease and asymmetry may have environmental or genetic origins (Thornill and Moller 1997). The genetics of disease susceptibility in relation to developmental instability have been investigated to some extent for humans by Russian geneticists. Botvinev et al. (1980) found that children with non-modal [rare] body mass suffered disproportionaly from a range of diseases including infectious diseases. These groups of children were characterized by deviant allele frequencies for blood group loci and lower levels of heterozygosity. Althukov et al. (1981) noted that children with acute pneumonia have a marked disposition to viro-bacterial diseases, a high frequency of small developmental anomalies, and a smaller body length and mass at birth. The study also demonstrated significant differences in four genetic systems between the two groups of children, a lower heterozygosity per locus, and a higher frequency of rare antigen combinations and rare electrophoretic protein variants….

More study needs to be done of course (I emailed a researcher who has done some relevant studies, but they seem unpublished for now). Heterozyogsity is not the only variable affecting symmetry and developmental stability (rare alleles probably alludes to deleterious mutations, though heterozygosity is related to this because of its masking potential). There are studies which show that lines of flies that have been separated for many generations may give rise to hybrids which are less developmentally stable. This is not due to a less robust immune system (flies don’t haven’t adaptive immune systems), but likely there are coadapted gene complexes which have evolved in diverging genetic backgrounds and the F1 generation exhibit deleterious epistatic effects.1 Speciation is probably one end outcome of this process as hybrids eventually become inviable.

Related: Here is the PUBMED query for “developmental stability heterozygosity.”

1 – Imagine an ancestral population with genotype AABB. In population 1 there might a mutation which gets fixed so that the population is now AAbb. Now imagine a second substitution so that population 1 is now aabb (the BB -> bb substitution happened first!). Assume that population 2 remains AABB. If there were epistatic interactions between the two loci, then an AaBb genotype might be less fit because of negative epistatic effects between the ancestral and derived states.

North African mtDNA lineages in Iberia

Dienekes has an interesting post which summarizes a recent paper that surveys “African” (north and sub-Saharan) mtDNA lineages in Ibera. Here is a snip of interest:

…However, the observed geographic structuring for one of the haplogroups does not fit the expected distribution provided by simplistic historical considerations. In fact, although for haplogroup L the north-south increasing frequency is corroborated by historical data, the opposite trend, observed for haplogroup U6, is more difficult to reconcile with the magnitude and time span of the Islamic political and cultural influence, which lasted longer and was more intense in the south….

U6 seems to be of north African origin, and the researchers are curious as to its north-to-south gradient. Let us grant that U6 is north African (as opposed to an ancient Iberian variant which they lacked resolution to distinguish) and that the north-south gradient is not an artifiact of methodological error. It might interest the researchers that in the author (who seems to be well versed in Iberian history) asserts that the Berber soldiers who first crossed over into Iberia were settled in the north of the peninsula (the Arab generals and tribes who crossed over received the choice southern regions). And it is also relevant that the first Berber settlers were likely “converted” to Islam within their lifetimes,1 so their fidelity to their new faith might not have been reinforced by custom, habit or tradition.

1 – I put converted in quotes because all histories that mention these Berber soldiers recruited by the general Tariq ibn-Ziyad offer that their embrace of Islam was quite pro forma.

localization of g

The extreme localization of g strongly confirms that psychometric tests are measuring something real, but also strongly suggests that g is only an aspect of intelligence. After all, the rest of the brain is also doing information processing of a variety of types. This information processing is vital to goal accomplishment. Ultimately, this should not be new news. There are plenty of examples of people being severely cognitively impaired by brain damage without loosing IQ. Lobotomy patients are one of the more historically important examples of this. At any rate, how do those here interpret this. Is there simply not enough normal variability between people in how their non-g associated information processing works for it to have practical significance?

Euro-radical Islam

Swung by a book store where I saw a Foreign Affairs article titled Europe’s Angry Muslims. You can’t read it online, but that’s OK, the piece is mostly a hurried jumble of assertions. Instead, check out this report, Bearers of Global Jihad? Immigration and National Security after 9/11, which is clearly the source of the article in Foreign Affairs. I haven’t read the whole ~150 pages, though I did jump down to the figures and data collection appendix. The point that I found unsurprising, though still concerning, is the prominence of Euro-Muslims in these jihadi movements (that is, second generation+). The unfortuante santorum of the Euro-Muslim cultural interface? Perhaps. So where’s the clean-up crew?

The Rebirth of Hebrew

I have at times been critical of the usual story of the rebirth ofHebrew as a spoken language (last time here). Usually they focus on thefactthat the ancient Hebrew language lacked vocabulary for many aspects ofmodern life, and onthe heroic story of Eliezer Ben Yehuda, who discovered and inventedmany of the missing terms, and raised the firstHebrew-speaking child in 2000 years. My instinctive criticism has beenbased on asingle observation: it is extremely difficult for an adult to learn aforeign language, and it almost never happens that a person will feelcompletely comfortable speaking a language acquired in adulthood. Andyet, millions of Jews did exactly that. For no practical reason, theyabandoned their mother tongues for Hebrew – a language, at the time, spoken bynobody. 

This is the real story of the rebirth of Hebrew: that millions ofpeople were persuaded to do this highly unnatural act. It is indeed amiracle (at least, if you will, in thesense of a seemingly highly unlikely event) that millions of Jewssuddenly began speaking a “dead” language. It is an event unique inhuman history, and it is very surprising to me that it has been solittle studied with any seriousness.

Before I get into what I contend is the real story, let me review the usual one (all ofwhich is true, by the way, just not as interesting). It goes likethis: Hebrew was kept alive for thousands of years after it ceased tobe spoken, as a language of scholarship and ritual, through the loveof the Jewish people. Toward the end of the 19th century, Jews began toleave their ghettos and participate in modern life. This wasaccompanied by a flourishing of the Hebrew language, such as hadn’tbeen seen since the Golden Era of Spain, in which Jews wrote in Hebrewabout all aspects of life. Eliezer Ben Yehuda moved to the Land ofIsrael, then ruled by the Turks (the region was not yet calledPalestine – that name would be be applied by the British only afterWorld War I) and endeavored to bring about the rebirth of Hebrew as aspokenlanguage. To this end, he compiled a dictionary of 500,000 items,rediscovering Hebrew’s lost vocabulary, and inventing hundreds of newterms. He also raised the first Hebrew-speaking family. Othersfollowed his lead, and spoken Hebrew was reborn.

While very nice, no part of this story is unique, except the part thatis left unexplained. There are many, many unspoken languages that have been kept alive over long periods of timeas literary or ritual languages, among them: Latin, Ancient Greek, Coptic, Ge’ez, Sanskrit, Avestan,Classical Arabic (as different from modern dialects as Latin is toItalian), and Classical Chinese– none of them have been revived as a spoken language. On the otherhand, many unwritten dialects have been elevated to written languages:At the time of the rebirth ofHebrew, ethnic minorities around the world were rediscovering theiridentities, and many spoke languages that lacked vocabulary for modernlife. Ben Yehuda’s work was certainly important for the revival ofHebrew, and he is justifiably celebrated, but similar thingshappened in Czech, Modern Greek, Finnish, and many other languages.Unexplained: How were millionsof ordinary Jews convinced to abandon their mother tongues?

I have finally discovered the answer, the missing link to the story. On the recommendation of Amritas, I ordered a copy of  by Benjamin Harshav.It is not an easy read. It’s written in a dry and academic style, so for lack of time and energy I readonly the second of its three parts, which deals directly with the rebirth of Hebrew. (The first part deals with thehistorical background, and thethird with Harshav’s translations of primary sources.)

In the last decades of Turkish rule of what would become Israel (atthe time there was no one name that referred to the whole area), thelanguage of government wasTurkish, the peasants spoke the local dialect of Arabic (which even tothis day is not written), the Jews spoke various languages, especiallyArabic and Yiddish, and education, such as it was, was mostly conductedin French and German. It was in this milieu that small groups of highlymotivated Jews founded new communitiesof like-minded peoplewith the specific purpose of creating a Jewish community that wouldembody their ideals, one of which was to speak Hebrew. The newcommunities included thecity of Tel Aviv, numerous small kibbutzim, and other agriculturalcommunities. It isimportant to understand that these were small self-selected groups: they did something that the vast majority are unwilling, or unable, to do.

It was within this small, self-selected population that Hebrew wasreborn as a spoken language. 

But it is not the end of the story: So asmall group of isolated, highly motivated, energetic people managed torevitalize Hebrew. How, then, did their numbers grow to the millionsthat they are today? 

After World War I, Turkey was defeated, and its empire divided between France and Britain. The League of Nations crafted the British Mandate to, among other things, “secure the establishment of the Jewish nationalhome” in Palestine, and Jews began to organize themselves into the politywhich was to become Israel. (Actually, even in Turkish times thevarious religious groups had a certain degree of autonomy, in what wascalled the millet system,which was preserved under the British Mandate, and persists in Israelto this day.) The Palestinian Jews were heterogeneous – religiously,politically, and linguistically. The dominant languages among themwere Arabic and Yiddish, neither of which were used for intellectualpurposes.Indeed, the intellectual languages had been French and German, but wereabout to be superseded by English. This state of diversity and flux wasprobably a contributing factor to the success of Hebrew, but was not,in my opinion, the main one, especially considering the fact thatalmost all Hebrew speakers at the time were native speakers of Yiddish,which could easily have followed the path of development of languagessuch as Czech. The reason Hebrew succeeded: The same,self-selected, group that pioneered the revitalization of Hebrew alsobecame the leaders of the Jewish community in Palestine.

And from then on, we are backto ordinary sociolinguistic processes. It has happened many, many timesthat a language spoken by a small but important group of peoplehas supplanted a much more widely-spoken language. To name just a fewinstances from historical times (many more can be reconstructed fromlinguistic evidence): Latin in the western Mediterranean, Greek in theeastern Mediterranean, Arabic in Mesopotamia, the Levant, and NorthAfrica, Hungarian in Hungary, English in Ireland. In Palestine, at thebeginning of the 20th century, that language was Hebrew.

ADDENDUM: At the end of book 2, Harshav examines the question ofwhether modern He
brew is really a “European” language. While he doesn’tgo quite so far as to say that it is, he seems to think that it hasbeen heavily Europeanized. I take issue with this claim. First of all,a speaker of modern Hebrew can understand the language of the Bibleabout as easily as a speaker of modern English can understand its KingJames translation, and Mishnaic (Talmudic) Hebrew is about as closeto modern Hebrew as 17th or 18th-century English is to the modernlanguage. That’s pretty close, I would say. Harshav quotes a typicalparagraph from a newspaper, and has this to say about it:

1. International words: kilometer, television, Antarctica, July, cabinet, Africa, NBC.

2. New Hebrew words for international terms: race, [television]networks, missile, launched, report, nuclear weapons, Minister of Tradeand Industry, area (in the sense of geographical area), the UnitedStates.

3. Phrases that represent Euro-American concepts: “hasbroadcast information stating that,” “a certain place,” “standardversion,” “denied reports,” “nuclear weapons,” “fifth of July,” “Israelwill not be the first,” “confined himself to stating the standardversion”

4. The microsyntax, concerning contiguous words, or immediateconstituents, is essentially Hebrew: the coordination of verb and noun;the use of the definite article, prepositions, and connectives; thegenitive phrases. Yet, the macrosyntax is European: the sentence in thefirst paragraph accumulates five stages of states of affairs, whichcould not be done in the syntax of traditional texts.

I find points 1-3 very odd. How can you talk about thingsthat go on in the modern world without having words for them? Are thosewords intrinsically Euro-American because the objects and concepts theyrefer to were mostly invented by Euro-Americans? He even admits inthe next paragraph that: “the roots of most of the words are Hebrew or quasi-Hebrew”!Point 4 is more interesting, it is the point I was addressing in thelinkabove. Itseems to me that the major transformation in the (written) language wasnot from Semitic toEuropean, but from a language meant to be spoken to a language meant tobe read. The Mishnaictexts were transmitted orally before they were written down, and their”macrosyntax”reflects that. A similar observation can be made in English whencomparing the works of Chaucer (which were meant to be read aloud) tomodern texts. For that matter, even today a well-written speech willhavesimplified sentence structure. Would you say that the language ofChaucer and Reagan is really Semitic? It should be pointed out that allthis Europeanmacrosyntax is achieved in Hebrew with the ancient set of particles, inotherwords the difference is one of degree not kind: no new kind of sentencestructurehas been invented. Indeed, the Hebrew of Maimonides(1135-1204), who was a native Arabic (Semitic language)speaker,has a macrosyntax not far from the modern idiom. Is complex sentencestructure a European characteristic or simply a modern one? Put anotherway, does a reading (as opposed to listening) audience inevitably leadto more complex sentence structure? I would be interested in data fromother languages.

honest disagreement

I would like to suggest that many of the people who argue against large genetic influences on behavior are actually doing so in good faith. They assert that environment influences behavior more than genes do because it is obvious that this is the case. It is, for instance, obvious that the difference between the behavior of the African American students and the European students in a typical urban school is trivial compared to the difference between the Franks and their genetic decendents the French, or even compared to the difference between Athens 700BC, Athens 200 BC and Athens 300 AD or between Rome in 0AD, Rome in 1000AD and Rome in 2000AD, or Scandinavia in 1600 and 1900. In a given century, the difference in violence between Columbia and Costa Rica (both Hispanic, 9-fold), between Japan (both East Asian 18-fold), or between Russia and Sweden (both European, 25-fold). By comparison, Linda Gottfredson asserts that intelligence accounts for a 7-fold difference in incarceration rate. If you have any familiarity with anthropology or with history then the evidence that culture matters immensely more than genetics is simply obvious.

The shocking thing which most people don’t realize is the underreported lack of measurable statistical consequences of parenting to the development of broad and predictively important measures of general ability or temprament. Obviously, parents can do much to encourage the development of expertise, from provision of a multi-lingual background to raising the Polgars or the Williamses, and expertise is far more impressive than sheer IQ in terms of the magnitude of the difference in ability it creates, and this also makes it seem that parents can obviously make their children smarter. They can do so, but a) in the vast majority of cases they don’t, and b) psychometrics are intentionally defined in such a manner as to be resilliant to cultural biases, training, etc. Importantly, defining psychometrics in such a manner as to define traits which are resistant to change does not leave us with predictively unimportant traits. Instead, these traits, which seem to almost entirely reflect genes and random developmental patterns are on a statistical level an extremely good predictor of life-outcomes.
