Humans are still evolving despite massive recent lifestyle changes, study finds – no way! =P – “The researchers analysed church records of births, marriages and deaths for 10,000 inhabitants of seven parishes in Finland since the beginning of the 18th Century and concluded that evolution is still occurring despite the dramatic cultural changes over the same period. ‘We are still evolving. As long as some individuals have more children and other individuals have fewer children than others, there is potential for evolution to take place,’ said Elisabeth Bolund of Uppsala University in Sweden. Dr Bolund and her colleagues at the universities of Sheffield and Turku in Finland…found that between 4 and 18 per cent of the variations between individuals in lifespan, family size and ages of first and last childbirth were influenced by genes. ‘This is exciting because if genes affected differences between individuals in these traits, it means they could also change in response to natural selection,’ Dr Bolund said…. The study, published in the journal Evolution, showed that the genetic influence on the timing of when someone is likely to begin a family and the overall size of the family has actually risen higher in recent times compared to the 18th and 19th Centuries. This means that modern humans could still be evolving because people are responding to Darwinian natural selection on the genetic differences between individuals within the population, the scientists said. ‘It is possible that we in modern societies have more individual freedom to express our genetic predispositions because social influences are more relaxed, and this leads to the genetic differences among us explaining more of the reproductive patterns,’ Dr Bolund said.” – h/t ed west!

Fossil Provides Evidence Of Early Human Migration To Europe“Some 55,000 years ago, a person — whether female or male, we don’t know — lived in Manot Cave in the western Galilee area of what is now Israel. Judging from the partial skull recovered from the cave, and described in Nature last week by Israel Hershkovitz of Tel Aviv University and his co-authors, the person was anatomically modern and closely related to the first modern humans who went on to colonize Europe.” – see also The Manot 1 skull and how we now look at Neandertal ancestry in early modern humans from john hawks.

Before Agriculture, Human Jaws Were a Perfect Fit for Human Teeth“The emergence of agricultural practices initiated major changes to the jaw structure of ancient humans, leading to dental problems we still experience.”

Half of our [european] ancestry comes from the Pontic-Caspian steppe“Here’s the latest teaser for the new David Reich et al. paper on the ethnogenesis of present-day Europeans. It’s part of an abstract for a seminar to be held by Professor Reich at Jesus College, Oxford, on February 9. Interestingly, it argues that migrations from the steppe resulted in a ~50% population turnover across northern Europe from the late Neolithic onwards.” – see also Strong (?) linguistic and archaeological evidence for steppe Indo-Europeans from dienekes.

Large multiallelic copy number variations in humans“Thousands of genomic segments appear to be present in widely varying copy numbers in different human genomes…. We find that mCNVs give rise to most human variation in gene dosage—seven times the combined contribution of deletions and biallelic duplications—and that this variation in gene dosage generates abundant variation in gene expression.”

Genetic analysis of human extrapair mating: heritability, between-sex correlation, and receptor genes for vasopressin and oxytocin“[W]e used data on recent extrapair mating in 7,378 Finnish twins and their siblings. Genetic modelling showed within-sex broad-sense heritability — i.e. the percentage of variation in extrapair mating due to genetic variation — of 62% in men and 40% in women. There was no between-sex correlation in extrapair mating, making indirect selection unlikely. Based on previous animal and human findings, we also tested for association of the arginine vasopressin receptor 1A gene (AVPR1A) and oxytocin receptor gene (OXTR) with extrapair mating. We found gene-based association for AVPR1A in women but not in men, and OXTR showed no significant association in either sex. Overall, these findings confirm genetic underpinnings of extrapair mating in humans, but do not suggest that women’s predisposition to extrapair mating is due to selection on men.” – h/t erwin schmidt!

Science Is Not Always “Self-Correcting”“Some prominent scientists and philosophers have stated openly that moral and political considerations should influence whether we accept or promulgate scientific theories. This widespread view has significantly influenced the development, and public perception, of intelligence research. Theories related to group differences in intelligence are often rejected a priori on explicitly moral grounds. Thus the idea, frequently expressed by commentators on science, that science is ‘self-correcting’ — that hypotheses are simply abandoned when they are undermined by empirical evidence — may not be correct in all contexts.” – no, indeed. =/ – from nathan cofnas.

Harsh environments and “fast” human life histories: What does the theory say?“A common belief among human life history researchers is that ‘harsher’ environments – i.e., those with higher mortality rates and resource stress – select for ‘fast’ life histories, i.e. earlier reproduction and faster senescence. I show that these ‘harsh environments, fast life histories’ – or HEFLH – hypotheses are poorly supported by evolutionary theory.” – h/t razib!

Amazonian horticulturalists live in larger, more related groups than hunter–gatherers“Endogamous marriages among kin create intensive kinship systems with high group relatedness, while exogamous marriages among nonrelatives create extensive kinship with low group relatedness. Here, a sample of 58 societies (7,565 adults living in 353 residential groups) shows that average group relatedness is higher in lowland horticulturalists than in hunter–gatherers. Higher relatedness in horticulturalists is remarkable given that village sizes are larger, harboring over twice the average number of adults than in hunter–gatherer camps. The relatedness differential between subsistence regimes increases for larger group sizes.” – h/t andrew sabisky! (thanks, andrew! (^_^) )

How secular family values stack up“[Bengston] was surprised by what he found: High levels of family solidarity and emotional closeness between parents and nonreligious youth, and strong ethical standards and moral values that had been clearly articulated as they were imparted to the next generation. ‘Many nonreligious parents were more coherent and passionate about their ethical principles than some of the “religious” parents in our study,’ Bengston told me. ‘The vast majority appeared to live goal-filled lives characterized by moral direction and sense of life having a purpose….’ [N]onreligious family life is replete with its own sustaining moral values and enriching ethical precepts. Chief among those: rational problem solving, personal autonomy, independence of thought, avoidance of corporal punishment, a spirit of ‘questioning everything’ and, far above all, empathy. For secular people, morality is predicated on one simple principle: empathetic reciprocity, widely known as the Golden Rule. Treating other people as you would like to be treated…. As one atheist mom who wanted to be identified only as Debbie told me: ‘The way we teach them what is right and what is wrong is by trying to instill a sense of empathy … how other people feel. You know, just trying to give them that sense of what it’s like to be on the other end of their actions.'”

(note: comments do not require an email. baby olinguito!)

at the beginning of last year, i outlined my best laid plans for 2014 — what topics i hoped to post about during the year — and, looking back on that post, i kinda-sorta stuck to that plan, but i did drop the ball in some instances (assimilation, for example — did i even post on that in 2014? don’t think so. did i ever mention that i come from a population that’s not very strong in future-time orientation? (~_^) ).

so, lemme try again this year. topics i plan on blogging about in 2015, not necessarily in this order (and with no guarantees!):

assimilation: “you keep using that word….” (hint: i don’t think assimilation is as easy as most people assume it is. example: the four anglo “folkways” of north america, a la albion’s seed, which STILL haven’t assimilated to one another after 300 to 400 years. and they all originated from the same country/broad cultural background!)

– speaking of assimilation, i’d also like to look at how populations and subpopulations self-sort (egs. the Albion’s Seed populations mentioned above, the American Nations pops discussed at length by jayman on his blog, The Big Sort, etc.) and the significance of that. the migration of populations/subpopulations basically.

manorialism: going to continue (and hopefully complete!) my planned series on the history of manorialism in europe and its different regional types.

– i will also dig in further into the origins of The Outbreeding Project in christian europe. (hint: i think it wuz the romans.)

violence: want to look more into the decline in homicides/impulsive violence in western european populations. last year i wrote a sneak preview of where i think my readings on this are leading, at least for england. we shall see how it pans out.

shame vs. guilt cultures: more on this, too.

the tswana: i’m VERY keen on taking a close look at the tswana of southern africa, because they are the one group outside of the arabized world which has a history of father’s brother’s daughter marriage (see here), but botswana is one of the most successful and functional nations in subsaharan africa. ‘sup with that?!

the french: i have started reading The Discovery of France (thanks to everyone who recommended it!), so i want to discuss the french a bit.

italians: my christmas present to myself was a copy of Making Democracy Work: Civic Traditions in Modern Italy by robert putnam et al., so i want to discuss the italians a bit, too.

democracy: really want to look at the histories/evolution of and differences between liberal and other forms of democracy (like consensus democracy). this is important, i think.

history of mating patterns in various populations: i’ll probably just continue trawling around for more info/data on the historical mating patterns of various populations. it’s what i do.

hbd between individuals (as opposed to between groups): ’cause i think we need to talk about that.

– prolly other stuff, too.

note that i do take reader requests! (especially if i find the topic interesting.) (^_^)

i will also have to find someone who can clone me so that i have the time to do all this blogging! (~_^)

also, my new year’s resolution is to no longer enter into “discussions” with people who feel that the existence of human biodiversity or having an interest in it is somehow wrong or waaaaycist or whatever. that is just a waste of my time. from now on, those people will simply be directed to my what is human biodiversity (hbd)? series.

that is all! (^_^)

visitors 2014 - map - turkmenistan

here are the top 20 countries in descending order. the difference between the u.s. and the u.k. is still roughly one order of magnitude. for the wiseguy (krakonos! =P ) who last year asked what the figures were per 100,000 people, total unique visitors from the u.s. for 2014 was 75 per 100,000 — for the u.k., 59 per 100,000 — for the czech republic, 17 per 100,000. (^_^) (note that these are just wordpress stats, so they’re not the greatest.)

Zigzags on a Shell From Java Are the Oldest Human Engravings“The early human Homo erectus also made the oldest known shell tools half a million years ago.” — see also: The art of Homo erectus“What we can say is that these artifacts carry information about the capabilities of their makers. The few non-perishable marked objects also speak to the likely presence of design in perishable elements of material culture. Clothing, however rudimentary, was likely to have been decorated in some way. Wooden tools were also probably notched and zigzagged — as the occasional bone and ivory implements suggest. They lived for the first time in a world that they could change.” – from john hawks.

Genetic diversity of Sub-Saharan Africa revealed[T]he researchers also found that there were more genetic similarities across Africa than they had thought. Dr Sandhu said: ‘The diversity among populations is not as diverse as we expected it to be….’ The researchers found that many Africans have some Eurasian DNA within their genetic ancestry, which suggests that Eurasians migrated back into Africa many thousands of years after they first left. And several of the populations were descended from the Bantu, a group that spread across Africa about 5,000 years ago.” — see also: The African Genome Variation Project shapes medical genetics in Africa.

and here is dienekes on the above study: African Genome Variation project paper“In too many papers to count, decreasing genetic diversity from East Africa was taken as evidence of an origin of H. sapiens in that locality and its expansion from there to Eurasia. This ‘East Africa=cradle of mankind’ theory has, as far as I can tell, nothing really to stand on. Granted, the oldest anatomically modern human remains have been found in East Africa 200-150 thousand years ago. But, the fact that old sapiens have been found in East Africa and not elsewhere is easily explained by the excellent conditions for preservation (as opposed, e.g., deserts or rainforests of Africa or elsewhere), and by the extraordinary effort by palaeoanthropologists in that area. One also needs to overlook a century of physical anthropology that concluded that East Africa was a contact zone between Caucasoids and Sub-Saharan Africans. We now know that there is no deep lineage of humans in modern east Africans. Take out the Eurasian ancestry and only a paltry Fst=0.027 remains with other Sub-Saharan Africans, a fraction of the Fst between, say, Europeans and East Asians.”

Living African group discovered to be the most populous humans over the last 150,000 years“New genetic research reveals that a small group of hunter-gatherers now living in Southern Africa once was so large that it comprised the majority of living humans during most of the past 150,000 years. Only during the last 22,000 years have the other African ethnicities, including the ones giving rise to Europeans and Asians, become vastly most numerous…. ‘This and previous studies show that the Khoisan peoples and the rest of modern humanity shared their most recent common ancestor approximately 150,000 years ago, so it was entirely unexpected to find that this group apparently did not intermarry with non-Khoisan neighbors for many thousand years….'” — see also The Least Bottlenecked Humans of All from razib.

Ants, altruism and self sacrifice“It’s the selfishness of genes that makes us unselfish…. ‘Group selection’ has always been portrayed as a more politically correct idea, implying that there is an evolutionary tendency to general altruism in people. Gene selection has generally seemed to be more of a right-wing idea, in which individuals are at the mercy of the harsh calculus of the genes. Actually, this folk understanding is about as misleading as it can be. Society is not built on one-sided altruism but on mutually beneficial co-operation. Nearly all the kind things people do in the world are done in the name of enlightened self-interest. Think of the people who sold you coffee, drove your train, even wrote your newspaper today. They were paid to do so but they did things for you (and you for them). Likewise, gene selection clearly drives the evolution of a co-operative instinct in the human breast, and not just towards close kin.” – from matt ridley. — see also: E.O. Wilson’s The Social Conquest of Earth from jason collins. h/t billare!

The research, conducted by scientists in Sweden and Finland, indicates that the link is not directly caused by fathers’ behavior but is instead explained by genetic factors that are shared by father and son.”

Are bright people normal?“‘We found no support for the genetic Discontinuity Hypothesis that nonadditive genetic variance is greater for high intelligence….'” – from dr. james thompson.

Booze culture may date back 10 million years say scientists“A new study suggests that primates may have begun drinking alchol 10 million years ago, as fermented fruit on the forest floor…. Experts at Santa Fe College in the US studied the gene ADH4 which produces an enzyme to break down alcohol in the body. It was hypothesised that the enzyme would not appear until the first alcohol was produced by early farmers. But scientists were amazed to find it 10 million years earlier, at the end of the Miocene epoch.” – (them’s *my* ancestors right there! (~_^) )

Psychiatry: End of the Road for “Endophenotypes”?“In a nutshell, the researchers ran seven different genetic studies to try to find the genetic basis of a total of seventeen neurobehavioural traits, also known as ‘endophenotypes’…. Essentially an endophenotype is some trait, which could be almost anything, which is supposed to be related to (or part of) a psychiatric disorder or symptom, but which is ‘closer to genetics’ or ‘more biologica’ than the disorder itself. Rather than thousands of genes all mixed together to determine the risk of a psychiatric disorder, each endophenotype might be controlled by only a handful of genes – which would thus be easier to find…. Over 89% of the searches came up null in this way; for eight of the seventeen traits, the researchers found no associated genes using *any* strategy.” – from neuroskeptic.

Unequal fates for maths superstars“The fates of US child prodigies of the 1970s reveal great accomplishments but strong gender differences…. [B]oth genders reported unusually high levels of satisfaction with their lives and careers. ‘It seems that both sexes got what they wanted from life, even if those things were somewhat different….'” – h/t charles! – see also: Sometimes men and women want different things from ben southwood.

A Magisterial Synthesis Of Apes And Human Evolution“[Russell H.] Tuttle’s tome is a grand synthesis of all the latest research and data about apes and their relation to us…. He believes that bipedalism preceded the development of the brain in early humans –and was likely something inherited from smaller apes already used to using their feet to move laterally along branches in trees. Although chimpanzees and bonobos are our closest relatives on the evolutionary tree, they do not represent in their own locomotion good proto-models of what led to human upright posture and walking.”

‘Superbugs’ Kill India’s Babies and Pose an Overseas Threat“A growing chorus of researchers say the evidence is now overwhelming that a significant share of the bacteria present in India — in its water, sewage, animals, soil and even its mothers — are immune to nearly all antibiotics.” – h/t razib!

The RNA World: molecular cooperation at the origins of life“The RNA World concept posits that there was a period of time in primitive Earth’s history — about 4 billion years ago — when the primary living substance was RNA or something chemically similar. In the past 50 years, this idea has gone from speculation to a prevailing idea. In this Review, we summarize the key logic behind the RNA World and describe some of the most important recent advances that have been made to support and expand this logic. We also discuss the ways in which molecular cooperation involving RNAs would facilitate the emergence and early evolution of life.”

A creeping incremental assault on academic freedom threatens not just what can be spoken aloud, but also what it is permissible to think: thought itself is to be subjected to management, so that its critical power is neutered or constrained….”

The Dark Enlightenment for Newbies“So what is dark about the Dark Enlightenment? Absolutely nothing. The Dark Enlightenment only looks dark in contrast to the blinding (as in, it blinds you) optimism of flash in the pan of blank slate equalism. The things that the DE contend about human nature — that parents naturally favor their children, that sexual attraction is a biological phenomenon, that some people are naturally smarter than others — were all accepted as common sense for most or all of human history. It is the unrealistic utopianism of modern liberalism which is ridiculously absurd. The Dark Enlightenment might be better termed The Return to Normalcy. So the phrase “Dark Enlightenment” might not be the best, but it has received enough attention that I don’t think we should abandon it.” – very nice post from empedocles.

Quick Questions for Peter and Rosemary Grant“There is widespread misunderstanding about evolution; that it occurs extremely slowly and therefore cannot be studied in a person’s lifetime. This was the view of Charles Darwin. Many biologists and others now know that this is not correct…. The idea that animals as large as birds might evolve before our eyes is not so well known, yet our study in the entirely natural world of Daphne Major island has revealed this does in fact happen when there is a change in the environment, and it takes place over a period as short as a year, and repeatedly.” – h/t billare!

But the pervasive occurrence of recoded stop codons, and the backchannel crosstalk between microbes and viruses, paints a more intricate picture of multilingual genetic instructions.”

Jelly genome mystery“The uniqueness of this ctenophore’s nervous system leads Moroz and his team to argue that it must have evolved independently, after the ctenophore lineage branched off from other animals some 500 million years ago.”

Genomic divergence in a ring species complex“Ring species provide particularly clear demonstrations of how one species can gradually evolve into two, but are rare in nature…. Here we use genome-wide analyses to show that, although spatial patterns of genetic variation are currently mostly as expected of a ring species, historical breaks in gene flow have existed at more than one location around the ring, and the two Siberian forms have occasionally interbred.” – h/t razib!

Natural selection and infectious disease in human populations“The ancient biological ‘arms race’ between microbial pathogens and humans has shaped genetic variation in modern populations, and this has important implications for the growing field of medical genomics. As humans migrated throughout the world, populations encountered distinct pathogens, and natural selection increased the prevalence of alleles that are advantageous in the new ecosystems in both host and pathogens. This ancient history now influences human infectious disease susceptibility and microbiome homeostasis, and contributes to common diseases that show geographical disparities, such as autoimmune and metabolic disorders.”

High genetic differentiation between populations often driven by classic selective sweeps“‘We demonstrate that while sites of low differentiation represent sampling effects rather than balancing selection, sites showing extremely high population differentiation are enriched for positive selection events and that one half may be the result of classic selective sweeps. Among these, we rediscover known examples, where we actually identify the established functional SNP, and discover novel examples including the genes ABCA12, CALD1 and ZNF804, which we speculate may be linked to adaptations in skin, calcium metabolism and defense, respectively. Conclusions: We have identified known and many novel candidate regions for geographically restricted positive selection, and suggest several directions for further research.'” – @dienekes’.

Furthermore, the more family intermarriage in a society, the greater the benefit of intermarrying on the number of children couples had. In other words, in societies in which people frequently married their relatives, intermarrying showed a stronger link to having more children.”

The mutation, called A111T, is found in virtually everyone of European ancestry. A111T is also found in populations in the Middle East and Indian subcontinent, but not in high numbers in Africans. All individuals from the Middle East, North Africa, East Africa and South India who carry the A111T mutation share traces of the ancestral genetic code.

Heritability of brain volume change and its relation to intelligence“Human brain volumes change throughout life, are highly heritable, and have been associated with general cognitive functioning…. Results show that changes in volumes of total brain (mean=-6.4ml; -0.5% loss), cerebellum (1.4ml, 1.0% increase), cerebral white matter (4.4ml, 0.9% increase), lateral ventricles (0.6ml; 4.8% increase) and in surface area (-19.7cm2, -1.1% contraction) are heritable (h2=43%; 52%; 29%; 31%; and 33%, respectively). An association between IQ (available for 91 participants) and brain volume change was observed, which was attributed to genes involved in both the variation in change in brain volume and in intelligence. Thus, dynamic changes in brain structure are heritable and may have cognitive significance in adulthood.”

Males showed a stronger positive relation between emotion regulation ability and regional gray matter volume (rGMV) in the right dorsolateral prefrontal cortex.

Good Fences: The Importance of Setting Boundaries for Peaceful Coexistence“Switzerland is recognized as a country of peace, stability and prosperity. This is surprising because of its linguistic and religious diversity that in other parts of the world lead to conflict and violence. Here we analyze how peaceful stability is maintained. Our analysis shows that peace does not depend on integrated coexistence, but rather on well defined topographical and political boundaries separating groups, allowing for partial autonomy within a single country. In Switzerland, mountains and lakes are an important part of the boundaries between sharply defined linguistic areas. Political canton and circle (sub-canton) boundaries often separate religious groups. Where such boundaries do not appear to be sufficient, we find that specific aspects of the population distribution guarantee either sufficient separation or sufficient mixing to inhibit intergroup violence according to the quantitative theory of conflict. In exactly one region, a porous mountain range does not adequately separate linguistic groups and that region has experienced significant violent conflict, leading to the recent creation of the canton of Jura.”

How a Protestant spin machine hid the truth about the English Reformation“It seems that in 1533, the year of Henry’s break from Rome, traditional Catholicism was the religion of the vast majority of the country. And in most places it was absolutely thriving. It had developed a particularly English flavour, with a focus on the involvement of ordinary people in parish churches, village greens, plays, and pageants – much of which seemed to involve a good deal of community parties, dancing, and drinking. It is true that English religion in the early 1500s was not especially studious or erudite. The people did not spend hours a day in biblical studies, contemplation, and moralising in the manner of the more intense European reformers. But England had a nationally cohesive spirituality that was alive and exuberant, with a distinctly community feel…. The conclusion of this modern grassroots scholarship is that bulldozing the Catholic Church off the face of medieval England was not a ‘bottom up’ revolution in which Henry merely acquiesced to his people’s wishes by throwing off a widely hated foreign domination. To the contrary, it looks increasingly like Henry and his circle imposed the Reformation ‘top down’, unleashing 100 years of deep anger and alienation that was only overcome by sustained politicking and ruthless force.” – h/t william briggs!

_____

bennett and lotus (in America 3.0) have the very right idea that anglo-saxons have been living in absolute nuclear families and behaving very “anglo-saxony” for centuries, but they’ve got, imho, the very wrong idea that if other peoples, non-anglo-saxon peoples, just start living like anglo-saxons in absolute nuclear families, they will — via some sort of cultural osmosis or something — start behaving all anglo-saxony, too. i’m not convinced. where, i would ask, is the evidence for this?

in the comments to one of my previous posts on this subject, i pointed out that, for example, italian american families, most of which have been in the u.s. for multiple generations now, are mostly absolute nuclear families — at least they appear to be on the surface. however, italian americans are really strongly attached to their extended families in ways that anglo-americans simply are not. here’s what i said (or, rather, what i quoted):

from “Community and Identity in Italian American Life” in The Review of Italian American Studies (2000) [pgs. 250-251]:

“Family gatherings…are still part of Italian American life….

“Italian Americans, even the more affluent, remain in inner-city enclaves more than other groups do. When Italian Americans do move, many times two or more generations are involved in the exodus to a new suburban residence. If they do not locate together, Italian American family members find residences within short distances of one another. When upwardly mobile children leave their inner-city parents for the suburbs, they visit them more than any other group. When leaving the extended family, Italian Americans most often move into some modified extended family arrangement characterized by continual economic and social exchanges. Similarly, Italian American middle- and working-class children are more likely to take geographical proximity to the family into account when considering college attendance. Contemporary Italian American youth spread their wings, but not too far.

“Although crude survey data indicate that Italian Americans are increasingly intermarrying, these measures miss the reality that many times it is the non-Italian marriage partner who is drawn into the powerful magnet of the Italian American family. In addition, intermarriage need no diminish the ethnicity of the Italian American partner nor does it mean necessarily that the offspring will not be reared in the Italian American way. Italian Americans are more entrepreneurial than most; family businesses, by definition, provide not only income and independence from outsiders but also keep the family together. Socially mobile Itlaian Americans are willing to sacrifice some career and employment opportunities in order to stay within the orbit of family life.”

and from The Italian American Experience (2000) [pgs. 210-211, 373-374]:

“For a long time, it was believed that this sequence was inevitably moving toward the complete absorption of Italian Americans….

“While intermarriage rates have remained lower than for other groups, exogamy among Italian Americans has greatly increased. Divorce rates, even for the most recent generation, remain very low compared to all other ethnic groups. Italian Americans still maintain a pattern of relatively frequent family contacts, with some studies actually indicating an increase in visiting among relatives for later generations. The strength of family ties has been identified as a deterrent to residential mobility and as a factor in the maintenance of Italian American neighborhoods….

“For Italians, family is an all-consuming ideal as is expressed by Luigi Barzini, among many others. For Italian Americans, ‘families’ usually include grandparents, whose influence on family life can be great….

“*L’ordine della familia*, which connotes precise boundaries, role expectations, and clear values for right and wrong behavior, is taught at a very early age and includes:

“- Always respecting parents and grandparents;
– Placing family needs first, staying physically and psychologically close to other members;
– Not talking about the family to outsiders;
– Sometimes maintaining secrets between family members to maintain personal boundaries; other family members do not need to know everythings, particularly if it will cause harm;
– Showing respect for authority outside of the family, but not trusting it;
– and Working hard, but also enjoying life; livining well is sharing food, music, and companionship with those one loves.”

yeah. just like in every sopranos episode that you ever saw. (~_^) why, then, don’t italian americans behave just like anglo americans? they’ve been in the u.s. a pretty long time now … and they live in absolute nuclear families. ‘sup?
_____

so i thought i’d check the gss (General Social Survey) to see how anglo-saxony italian americans are. unfortunately, the gss numbers for italian americans with all four grandparents born in the u.s. (in other words, being at least third generation or more, which ought to make one really american, right?) are really tiny. dr*t.

so, i decided to look at german and irish americans instead in comparison to english/welsh americans — to see how anglo-saxony those two groups have become (quick answer for those tl:dr folks out there [SPOILER ALERT!]: not very).

before we start, though, t. greer recently pointed out the ever-present problem in these self-reported sort-of surveys and that is that we’re relying on how the respondents “identify” ethnically. how “german” are any of the “german americans” in the gss? who knows? however, the same problem should apply, i would think, across the board here with the self-identified english/welsh, german, and irish americans (i purposefully have NOT used the “just american” category since i want to get at how anglo americans behave), so it should all even out (i hope).

i’ve picked out questions that related to: “civicness” (see previous posts here and here for more on what that is), because the english are VERY civic-minded; “familism” (see here and here), because the english are NOT very familistic; and a couple of ones related to ideas about government and the u.s. that i thought sounded pretty anglo-saxony and that i just found interesting. let’s start with those.

for all of these questions, i’ve shown the results for respondents with all four grandparents born in the u.s. AND for all respondents — just because i can (and i thought it might be interesting to compare). for ethnicity i selected the “COUNTRY OF FAMILY ORIGIN [ETHNIC]” parameter. [click on charts for LARGER view.]

should we “Allow public meeting protesting the government” [PROTEST 1]?:

gss - anglo saxons - allow public meetings protesting government 02

england/wales: n=455 for all/n=244 for 4 grandparents
germany: n=604/n=248
ireland: n=412/n=151

should we “Allow publications protesting the government” [PROTEST 2]?:

gss - anglo saxons - allow publications protesting government 02

same n’s as above.

“How close do you feel to America” [CLSEUSA]?”:

gss - anglo saxons - how close do you feel to america

england/wales: n=262/n=205
germany: n=367/n=242
ireland: n=245/n=170

wtf german americans?!

so on those three questions there’s anywhere from a four to a fourteen point spread between the responses of german and irish americans versus anglo americans, with anglo americans consistently being more pro allowing protests against the government of different sorts and more pro american. i agree, four points is not much of a difference, but fourteen is — and, as you’ll see below, this is a consistent pattern, i.e. that third+ generation anglo americans are more anglo-saxony than either third+ generation german americans or irish americans.
_____

the familism questions (again, see previous posts on familism here and here). for all of these:

england/wales: n=96/n=72
germany: n=150/n=100
ireland: n=106/n=70

“How often does R[espondent] contact uncles or aunts [UNCAUNTS]?”:

gss - anglo saxons - how often contact uncles aunts

“How often does R contact nieces or nephews [NIECENEP]?”:

gss - anglo saxons - how often contact nieces nephews

“How often does R contact cousin [COUSINS]?”:

gss - anglo saxons - how often contact cousins

the differences in the familism scores, then, are not that great. still, with the exception of “how often contact nieces/nephews”, both the german and irish american scores reflect greater familism on their part than on the anglo americans. slightly greater, but greater nevertheless.
_____

finally, the civicness questions (again, see previous posts on civicness here and here). for all of these:

england/wales: n=96, n=72
germany: n=150, n=100
ireland: n=106, n=70

“Participated in a charitable organization in past 12 months [GRPCHRTY]”:

gss - anglo saxons - charitable organization

“Participated in activity of a political party [GRPPOL]”:

gss - anglo saxons - political party

“Participated in activity of a political party [GRPUNION]”:

gss - anglo saxons - trade union

“Participated in activity of church in past 12 months [GRPCHURH]”:

gss - anglo saxons - church

“Participated in sports group in past 12 months [GRPSPORT]”:

gss - anglo saxons - sports group

so, again, with the exception of participation in a sports group, the anglo americans score higher than the other two groups on all of the questions. the differences range from just two points to eighteen. in the case of sports, german americans scored just a tad (one point) higher in participation than anglo americans and irish americans four points, but anglo americans are out in front on the other four civic behaviors.

you might be thinking that the not-all-that-great differences in civicness scores between these three groups illustrates that german and irish americans are, in fact, becoming more like anglo americans. (why it should be taking so long is curious though — these are THIRD+ generation groups after all.) however, if we look at the very same questions from the world values survey (2005-2008 wave), we find the SAME pattern!: great britain ahead of germany on all the civicness metrics. (unfortunately, ireland was not included in this wvs wave.) (see also previous post.)

great britain: n=1012-1035
germany: n=2039-2050

note that non-whites are included in these figures. ethnicity was, apparently, not asked in germany, because … well, you know … everybody’s the same, so i didn’t parse out non-whites from the results for britain, either. doesn’t seem to make much difference to the scores — one point here and there — since there are not that many non-whites included in the british survey.

gss - anglo saxons - wvs civicness metrics

as you can see, same patterns again: great britain ahead of germany on all of these civicness measurements. and the differences between the two populations — the (mostly) anglos in britain and the (mostly) germans in germany — are very similar to the differences between the two populations in the u.s. — AFTER THREE+ GENERATIONS of being in the u.s.!:

– charitable organization: u.s.=11%, euro=21%
– political party: u.s.=6%, euro=6%
– trade union: u.s.=5%, euro=8%
– church: u.s.=3%, euro=1%
– sports group: u.s.=1% (higher in germany), euro=5%

i strongly suspect that german americans are not becoming like anglo americans, or if they are, it’s NOT happening very quickly. german americans:anglo americans::germans:anglos. nor do i see any reason to think that other groups like the irish or the italians are becoming anglo-saxons either.
_____

the evidence i’ve presented is not conclusive. obviously. (it’s just a blog post!) Further Research is RequiredTM.

anglo-saxons — or the english of today — have been living in absolute nuclear families for a very long time, but this is more of a symptom of anglo-saxonness than its cause (although there undoubtedly has been feedback between the family type and societal structures). it took the anglo-saxons a looong time to get from being a kindred-based germanic “tribe” to the anglo-saxony individualistic-collectivistic english society that we know today (and have known since about the 1200s-1400s). it’s going to take other societies a similarly looong time to get to the same place — if they will even ever get to exactly the same place — since we are talking about biological processes here including the selection for certain behavioral traits. simply plunking germans — let alone italians (especially southern italians!) — down in absolute nuclear families will NOT turn them into anglos overnight. apparently it won’t even turn them into anglos in three+ generations.

no. anglo-saxons are exceptional. innately so. we should try not to destroy that, since it benefits so many of us.

Diabetes’ genetic underpinnings can vary based on ethnic background, Stanford studies say – the researchers “found a clear geographic pattern in the genetics behind type-2 diabetes. The genetic risk is highest for Africans and drops along the trajectory the first humans took when migrating out of Africa toward East Asia (primarily Japan, China and Korea), where diabetes-linked genes appear to be more protective. Based solely on what is currently known about type-2 diabetes genetics, native Africans would appear to be at higher risk for diabetes, while East Asians would appear to be protected.” – see also genetic risk world map|diabetes.
