Antisemitic LBK Undead Blitz Megalithic France

I’ve previously warned of the threat presented by the racist LBK (proto-KKK?) culture to Civilization As We Know It.  If only unbiased scientists like Stephen Jay Gould were alive today to broadcast to the 125 IQ coeds with big bazooms the true interpretation of these new “data”:

The widespread distribution of the N1a lineage in Early and Middle Neolithic northwestern Europe may indicate genetic continuity from Mesolithic populations.  This scenario would support a Mesolithic contribution to the earliest Neolithic of Atlantic Europe. This would imply that the N1a lineage was already common in indigenous north European populations and that the spread of the Neolithic was principally the result of cultural diffusion. Although so far the N1a lineage has not been encountered among late European hunter-gatherers in central and north Europe (Bramanti et al., 2009; Malmstro¨m et al., 2009), it is worth noting that less than half of the hunter-gatherers’ paleogenetic data come indeed from the pre-Neolithic period (predating LBK expansion). Finally, no paleogenetic data currently exist for the Mesolithic period in Western Europe. This prevents any conclusion being drawn about N1a occurrence during the Mesolithic period in those regions.

Debunking a racialist myth about the genetic variation between dog breeds

In a previous entry, I made the following comment:

For dogs it’s:

Canus (genus) lupus (species) familiaris (subspecies).

There are 37 subspecies of Canis lupus.

Breeds don’t qualify as subspecies.  The genetic differentiation between dog breeds is tiny (don’t know exact percentage, but it’s much less than between human races).

This is not true. 

I’ve heard this bit about limited genetic differentiation in dogs repeated a number of times in racialist circles.  I remember Jared Taylor using it in a debate with Tim Wise. 

Steve Sailer wrote:

Dog genome research progress has been fairly slow, partly for economic reasons, but partly, I suspect, because dogs aren’t really that variable, strange as it may seem. Without breeding, dogs in the tropics seem to wind up medium size, short-haired, and yellowish, reddish, or brownish.

My hunch is that genetic diversity in dogs will prove to be narrow but deep, focusing on a small number of genes that vary sharply, whereas genetic diversity among humans will prove broader but shallower than among dogs, involving more genes than among dog breeds, but not as sharply defined. [ed- this last part might be true- there may be fewer SNPs in dogs, but I’m not sure about this.  It is certainly true that indivisual SNPs have much larger phenotypic effects in dogs, which is one reason why a comparison between dog breeds and human races could be considered inappropriate]

The myth seems to originate from the book Race: The Reality of Human Differences, by Frank Miele and Vincent Sarich (which I also read several years ago).  Miele writes:

I (Miele) then raised the question of dog breeds. I’ve liked dogs since I was a kid and am now on my third (the first two bullterriers and now a Great Dane).  I’ve also been to a number of dog shows and even took my first bull terrier to an AKC championship.  In addition, I’ve read widely both in the popular literature on dogs as well as in scientific journals that cover canine behavior genetics.  I pointed out to Vince that there were huge differences between dog breeds, both in morphology and in behavior.  How different were they genetically?  Had the same methodology been applied to sorting out dog breeds as was described for humans in Chapter 5?  With such large morhphological and behavioral differences, shouldn’t there be large DNA differences betwen the breeds? (It is now well known that the morphological and behavioral characteristics that distinguish breeds from one another are genetically bases.) Vince’s surprising answer was that (at that time) not only were there no known DNA differences between the breeds, but these methods couldn’t even distinguish between domestic dogs and wolves.  Although it was possbile to identify individuals with the same microsatellite approach that has been in use for the past two decades, only this year (2003) have researchers been able to distinguish between a few dog breeds by DNA differences.

Miele also repeated parts of this in an online essay published on Vdare in 2008:

Despite minimal genetic differences, human physical racial differences are clearly observable.

Likewise for dogs. But only recently has genetic analysis been able to distinguish between breeds—or even between dogs and wolves.

Vince’s surprising answer, though, was very misleading.  Or Miele misinterpreted what he was told.

In reality, dog breeds are much more genetically diverse than human races, and they can be classified very accurately.

In a 2004 paper in Science, Parker et al. showed that very accurate classification is possible (410 of 414 dogs were correctly assigned to their breed).  They also showed by Analysis of Molecular Variance (AMOVA, a technique often used for estimating genetic variability using microsattelites and repeats, although it can also be used for SNPs) that 27% of genetic variance is between breeds.  Using SNP data, they calculated an Fst distance between the breeds of 0.33.  A recent paper on a genome-wide SNP analysis on 919 dogs from 85 breeds, showed by AMOVA that 65.1% of genetic variance was within breeds, 31.1% between breeds, and 3.8% between breed groups (they defined 10 different groups:  Spaniels, Retrievers, etc.).  They also that as few as 20 diagnostic SNPs can be used to accurately classify dogs into their breeds.

How does the genetic variation in dogs compare to that of humans?  AMOVA analysis of humans shows that approximately 85% of variance is between individuals, 5% is between populations in the same racial group, and 10% is interracial (btw, this number is also close to the updated Fst measurement of Xing et al.).  The average Fst distance between human races is approximately 0.15.

So, we can see that dog breeds are actually much more variable than human races.  The myth of limited genetic diversity prevalent in racialist circles (to which I also fell victim) needs to be dispelled.

Invasive subcon keeps it ‘empirical’

Razib writes the following, in response to a recent paper highlighting the exquisite structure detectable at the village level in Europe:

The utility of this sort of data collection and analysis in the modern world is an empirical question. On the one hand many Europeans are relatively less inclined to move in comparison to Americans. And yet the breaking down of borders with the European Union and the likely need for a more productive economic sector on that continent because of changing demographics point to greater mobility, migration and mixing, which would make these sorts of studies of only near-term use. Of more interest to me are going to be fine-grained analyses of social groups. For example the Indian caste system. Last fall in the Reich et al. paper the authors seemed to be indicating the likelihood of a lot of between population variance groups these groups. It doesn’t matter if a particular Bania sub-caste from Gujarat is scattered across the world, from Kenya to England to the United States. They may all still marry amongst a set of individuals who hale [sic] from the same original few villages.

Good times.

No, an empirical question is one which can be answered by direct observation.  The direct observation here is the exquisite genetic structure of Europeans. By this leap of illogic he can quickly arrive at the conclusion that such studies are ‘only of near-term use.’ Razib wants to keep things ‘empirical’ so people don’t ask important questions, like “Is this worth preserving?”.  This way, Razib can celebrate the ‘good times’ that are the detection of village-level structure of subcons in White countries that are being transformed by 3rd world immigration.  But people will wake up to this arrogant, invasive subcon.  The conservationist instinct is one of the strengths of Europeans.  Making the case for returning invasive species to their lands of origin will be one part of doing what me must to remain who we are.

Craig Venter debunked by his own DNA, once again

Craig Venter, recently made in/famous by his work on creating synthetic bacterial life, has long been infamous in racialist circles for his wild statements about human biodiversity, including one about all humans being ”essentially identical twins.” Following the initial release of the draft sequence for the human genome, few scientists did as much as Venter to downplay human genetic diversity. 

For the first few years after the release of the human genome sequence, the consensus figure was that any 2 people have 99.9% of their DNA sequence in common.  You still hear this number cited today by people who are not aware that Craig Venter himself, or rather, his DNA, showed in 2007 that this was an underestimate.  The 0.1% was based predominantly on SNPs (single nucleotide polymorphisms, i.e. single base pair differences), but neglected structural variation like CNVs (copy number variants).  The authors showed 4.1 million structural variants (22% of which were structural) that covered 12.3 megabases (74% of which involved structural variation).  The end result was a new estimate of 99.5% similarity between 2 human genomes.

Now, a recent paper, again using Venter’s DNA, shows that 99.5% was also an underestimate.  The authors report almost 41 megabases of new structural variation in the Venter genome.  When ones accounts for differences to the reference human sequence due to SNPs (0.1%), inversions (~ 0.3%), and indels/CNVs (~ 1.2%), the percent similarity between human genomes is now estimated to be ~ 98.4%, in the range of previous estimates of human/chimpanzee similarity.

Non-parametric Analysis of Population Structure

I recently had a chance to look over this paper which n/a had pointed out a while back on his blog.  Unlike popular Bayesian clustering approaches such as structure and BAPS, the authors’ new method (Maximization of Genetic Distance, MGD) does not make assumptions about intra-population or inter-locus allele distributions, namely that they are in Hardy-Weinberg and linkage equilibrium.  In this sense, the method is analogous to statistical methods like Wilcoxon rank-sum (Mann-Whitney) and Kruskal-Wallis, which are non-parametric versions of the t-test and one-way ANOVA, respectively (these methods are non-parametric in that they do not assume a specific underlying distribution for the data, in these cases Normal). 

MGD uses a simulated annealing algorithm to find the partition that maximizes the average genetic distance between populations.  In this respect, it is very similar to traditional clustering methods like k-means.  One interesting feature of the method is that it permits use of different distance measures.  The authors use Nei’s D, which, while superior to Fst/Gst in that it is less sensitive to the level of heterozygosity, has the disadvantage of approaching infinity under certain conditions.  Jost’s D, a more recently developed measure, may prove superior here.  In simulation studies, the method performs better than structure or BAPS when the number of clusters is large or population structure is more complex.  However, only structure gives the correct clustering solution when Fst is as low as 0.01.

Perhaps the most interesting result from the paper is the following, which compares the clustering solutions of structure and MGD over different numbers of desired clusters (2-7).  The data set used is the HGDP microsatellite markers from Rosenberg’s 2002 paper.

(Af: Africa; E: Europe; ME: Middle East; CSA: Central-South Asia; EA: East Asia; O: Oceania; Am: America; Kal: Kalash)

MGD appears to be more robust, in the statistical sense, than structure, as would be expected from a non-parametric method.  The Kalash are no longer a structural outlier.  At K = 7, we get clusters corresponding to the main geographic regions of the HGDP populations.  Perhaps most interesting is the result for MGD at K = 6.  Here, we see the Middle Eastern populations emerging as a new cluster, while Oceanians and East Asians remain together in one cluster.  According to Cavalli-Sforza’s Fst distance matrix (Table 2.3.2 in HGHG, or Table 3.2 in Salter’s book), the distance between Europeans and non-European Caucasoids is 0.0155, while the distance between East Asians and New Guineans/Australians is 0.0734 (and 0.0724 for Pacific Islanders).  The results with MGD suggest some higher-level genetic difference between Europeans and Middle Easterners that is not being captured by Fst, which is an imperfect measure of genetic distance.  As a caveat, it’s worth noting, though, that the Fst distance between non-European Caucasoids and Europeans is approaching the limits of the MGD method. 

Based on the results of this paper, in particular the nonexistence of the Kalash as a separate cluster using MGD, it is questionable as to whether structure always provides the ‘most correct’ answer.

Seeing the Structure for the SNPs

Single locus based measures of genetic variance are the source of much of the misunderstanding about the existence of race and ethnicity.  They have also been used by politically motivated scientists to discredit the concept of race.  When arguing online with race-deniers, race realists often refer to A.W.F. Edward’s article on “Lewontin’s Fallacy” as a means to counter the claim that race cannot exist because most of the genetic variability (single locus based) is within human groups.  There was also a recent demonstration by Harpending (see Appendix) that the diversity loss of having all races spare one vanish from the earth would be the same as that from having all members of a race spare 2 couples vanish.  Graphic rebuttals are often PCA (or MDS) plots or structure clusters from studies that use hundreds or thousands of SNPs or microsattelites.  Recently, I came across the following, in a figure from a 2008 Nature paper, which nicely shows how deceptive statements about racial commonalities can be when based on single locus measures:

At the single locus level, 81.2% of SNPs can be found in all 5 major races.  However, when allelic correlation structure is considered, only 12.4% of haplotype clusters are common to all. 

This figure makes a good addition to the rebuttal toolbox for online discussions with race-deniers.

Revisiting Race in a Genomic Age

The book Revisiting Race in a Genomic Age (2008) has numerous academic contributors—most or all on the Left. Their collective angst stems from the wide popularization of several key developments from genetic research. First, racial differences are very important when it comes to how people are treated medically. Genetic differences affect response to medicines and other treatments. It is difficult to argue that we are all the same when there are medical treatments directed to persons of one race or another. Forensic science, prominent in television and movies, shows that race can be determined from a bit of DNA.

In a recent series of papers, population geneticists argue that the genome holds the key to medically and forensically significant biological differences among human racial and ethnic populations. Increasingly, genetic variation among human populations—races, ethnicities, nationalities—is an object of keen biomedical interest.

Second, there is a great deal of interest in genealogy. What really bothers race deniers is that Blacks have a high level of interest in “geographic ancestry”: the use of genes to determine not only their race, but also their tribal origins (even though there is no real difference between a race, a tribe, etc.). “Geographic ancestry”, “population group”, or “continent of ancestry”, are code words used by liberals to avoid the reality of race. They wish to protect Blacks from the stigma of racial differences; at the same time blacks are embracing genes to determine their racial background.

Selected behavioural traits by race

It would be interesting to build up as detailed a picture as possible of selected behavioural traits by race, and even within-race.  We have, I think, a pretty good idea of the sociobiology of Europeans.  We talk a lot about issues of individualism and altruism, intelligence, civilisational capacity, faith, sexual mores, and so on.  The tendency is, though, to see other racial and ethnic groups through the prism of their competition with us - some more than others, of course.  When we contemplate their evolutionarily-selected behavioural traits, which would likely not be adaptive for us, we may be tempted to express the strong emotional signals that necessarily accompany maladaptiveness.

I would like to avoid that kind of “noise” and, if possible, collate through the comments thread as many ideas as we can muster about the traits of Ashkenazics and other Jews, Eurasians, East Asians, South Asians, Mexicans, Arabs, North Africans, Sub-Saharans, and so on.

For example, one can see that Han Chinese place a very high value on conformism which appears to include a strong desire for approval from authority, and on honour which in the negative form of face-saving may be linked to the same desire.  Japanese, which might in large measure mean Yamato, are perhaps weaker than Han on conformism but stronger still on honour.  Even so, Japanese parents will allow school teachers to beat any sign of rebellious individualism out of children who are scarcely more than infants (damn, you see what I mean about moral interpolation).

These are both populations which exhibit the adaptiveness in a northern hemisphere, cold-climate environment of high-K strategies for intelligence.  But how different the outcome is from the European experience, and how fascinating that difference.

How fully can we explicate that difference on its own terms?  And what of other group differences?

The Specter of Genetic Communism

Racial cohesion is a result of different factors, important ones being similar physical appearance and behavioural patterns (whose aggregate phenotype is a ‘culture’ or ‘civilization’).  The difference in physical appearance between races is obvious and results in implicit negative attitudes towards racial others.  Aggregate behavioural differences can also be stark and are a major cause of the displacement of native Whites via ‘White Flight’.

One of the main weapons in the elite arsenal to weaken criticism of race-replacement has been the PC mythology on race:  that it doesn’t exist, that differences are only skin deep, that differences are the legacy of White racism, and corrective social programs can equalize achievement.  Although researchers have long ago taken the hammer to many of these idols, their worship in the popular press and political class continues.  The torrent of data coming from projects like HapMap, however, now portends a coming twilight.  Heretical musings bubble up in establishment organs like Slate and the NYT (though orthodoxy still prevails overwhelmingly).  Social programs, like No Child Left Behind, continue to fail.  The general avoidance or dismissal of heritable differences between human groups by the left (who do the elite’s ideological programming) is becoming less viable as a strategy for suppressing dissident views on race.

The crumbling of the dominant racial mythology and increasing racial tension undermine the legitimacy of Western elites who impose, or fail to prevent, race-replacement.  As Whites become increasingly displaced and dispossessed, their discontent weakens the foundations of the current political structure.

What is to be done?

Pretty picture of Europe

Right here.

From Nature:-

Genes mirror geography within Europe

Understanding the genetic structure of human populations is of fundamental interest to medical, forensic and anthropological sciences. Advances in high-throughput genotyping technology have markedly improved our understanding of global patterns of human genetic variation and suggest the potential to use large samples to uncover variation among closely spaced populations1, 2, 3, 4, 5. Here we characterize genetic variation in a sample of 3,000 European individuals genotyped at over half a million variable DNA sites in the human genome. Despite low average levels of genetic differentiation among Europeans, we find a close correspondence between genetic and geographic distances; indeed, a geographical map of Europe arises naturally as an efficient two-dimensional summary of genetic variation in Europeans. The results emphasize that when mapping the genetic basis of a disease phenotype, spurious associations can arise if genetic structure is not properly accounted for. In addition, the results are relevant to the prospects of genetic ancestry testing6; an individual’s DNA can be used to infer their geographic origin with surprising accuracy—often to within a few hundred kilometres.

From Dienekes’ post:-

The realization that not only major continental races, but also ethnic groups are biological entitites goes against the prevailing politically correct orthodoxy. According to this orthodoxy, European nations are artificial cultural constructions whose members share a “myth” of common origins; they are “constructed” products of the last few centuries; ethnic identification is a subjective notion of self-identity, rather than an objective notion of ancestry and homeland.

It now appears that while European nations are not races, they are, nonetheless, biological populations, occupying specific positions along the Caucasoid genetic continuum, and distinguishable from most other European nations, if not always their immediate neighbors.

Sperm and egg donor registries.

An article in the Chicago Tribune discusses the need for setting up a registry of egg and sperm donors. The argument for such a need seems a bit odd. The danger it seems is that a donor may have a condition that manifests itself later in life, like colon cancer, and they should be able to inform those children who carry the donors genes of the condition.

I don’t see how that is any different from parents who have family histories of ailments going ahead with having children. It is fairly accepted I assume that few of us are without at least some serious deleterious mutations of this sort or that. A registry however would be a good way to track quality donors by lineage, keeping track of the quality of the offspring, and using certain family lines as regular donors.

Are Jews White?

Are Jews White?

by

Robert E. Reis

The Southern Poverty Law Center has declared war on Professor Kevin MacDonald, but the SPLC has not declared war on Jared Taylor and American Renaissance.

The SPLC has good things to say about American Renaissance and about Jared Taylor.

The SPLC mentions that American Renaissance consistently deletes readers’ posts critical of the Jews. The SPLC describes American Renaissance as “100% clean” white nationalism.

Jared Taylor and American Renaissance cater to modern non-Orthodox Jews by claiming that Jews are white.

E. Michael Jones believes that the American Renaissance is “the white man’s version of the NAACP, which is to say, one more organization which manipulates the race issue in the interests of the revolutionary Jews. The main purpose of the American Renaissance is to convince deracinated Protestants that Jews are white, and, therefore, no threat to their interests.”

If non-Jewish white people see Jews as white people in the context of the relationship between whites and blacks in America or in the context of non-white immigration to white countries, then Jews disappear from the radar screens. Ordinary white people will not suspect Jews and Jewish groups of having hidden motives when they make policy recommendations.

Are Jews white? Or are they a genetic clustering that is “acting in a way that cannot please God and makes them the enemies of the whole human race” (I Thess 1:15).

Eugenics in a most unlikely place.

It is common practice, now that eugenics in moving quickly within the science of reproductive genetics, to dismiss eugenics as pseudoscience. In fact, eugenics never ceased to play its part in demographics as it went from negative eugenics to Planned Parenthood, to preimplantation diagnosis, to sperm banks and attempts at cloning. Along with this goes the unfolding testing of individual’s genetic code revealing their personal genealogy or racial makeup.

In Darwin Day in America: how our politics and culture have been dehumanized in the name of science by John G. West, 2007, a very typical approach is used to delegitimize eugenics:

“For decades, eugenics was embraced as legitimate by America’s leading scientists and scientific organizations such as the American Association for the Advancement of Science. Critics of eugenics, meanwhile, were stigmatized as antiscience and religious zealots. Yet the critics turned out to be right.”

In most books that mention eugenics, this is the standard rebuttal—a factual sounding statement without substance. Eugenics is a very broad area of scientific inquiry and breeding practice—as simple as picking a healthy mate to assure healthy children to selecting a defective fetus to be aborted.

Then I came across a book that reveals just how progressive Israeli eugenics is in comparison to Germany, with most modern countries in-between. A Life (Un)Worthy of Living: Reproductive Genetics in Israel and Germany, by Yael Hashiloni-Dolev, 2007, shows that the Israeli attitudes are closer to the progressive era attitudes that prevailed 100 years ago. As a modern, progressive state that embraces science and eugenics, it is quite absurd to claim that there is anything but solid science driving the genetic revolution, and one cannot separate eugenics from this scientific advancement. In Israel, the purpose is to have only healthy children, have as many children as possible, while giving preference to the life of the mother over the fetus where the interest of each is in conflict.

Racial Genetic Similarity and Difference: A New Study

One scientific topic that I have previously discussed is the biological validity of the race concept. This, unfortunately, has become necessary, because some people, perhaps with political motivations, assert, contrary to the evidence, that “race does not exist” and that race is a “social construct” with “no biological foundation.” These views have been effectively refuted in various forums, and more objective researchers support the race concept as well, if for no other reason the important medical implications of racial differences.

One popular and misinterpreted finding that has been eagerly grasped at by those who preach that “race is not real” is derived from the work of Richard Lewontin, which demonstrated that more genetic variation exits within rather than between groups. I have previously explained how Lewontin’s finding in no way discredits the race concept. However, there are “anti-racist” activists who still claim, based on their misinterpretations of population genetics, that individual Europeans (“whites”) can be more genetically similar to sub-Saharan Africans (“blacks”) than to other Europeans. Until now, there has been no formal proof that this assertion is incorrect. I am now pleased to say that a recent scientific paper has delved into this very topic and that the findings of this paper clearly demonstrate that the race deniers are wrong. First, let me give a brief introduction for the sake of clarity.

Kinship and Fertility

by JW Holliday

Guessedworker has expressed interest in the paper An association between the kinship and fertility of human couples, Helgason et al., Science 319:813-816, 2008, from the deCODE Genetics research group.  Therefore, a few comments are appropriate.

This paper demonstrates that, in an analysis of Icelandic couples born between 1800 and 1965, there is a “significant positive association” between kinship and fertility; maximal reproductive success was observed for couples with kinship relatedness at the level of third or fourth cousins.

The authors conclude that these differences in reproductive success (i.e. fitness*) have a “biological basis” - that is, a genetic basis.

I’d first like to reproduce several comments from the paper (blockquote) with some of my own (plain text) comments included.  I will then briefly cite some reviews of this paper, and then, finally, will reintroduce the concept of outbreeding depression which was previously discussed at “Majority Rights” with respect to the pro-miscegenation propaganda of Alon Ziv.

First deCODE:

Although Icelanders have experienced a socioeconomic transformation from 1800 to the present (14, 15), accompanied by a reduction in family size and decreasing kinship between couples (Table 1), essentially the same relationship between kinship and fertility was observed at the beginning and end of this 200-year period (fig. S2). By estimating kinship between spouses at a genealogical depth of up to 10 generations, it was possible to examine the association with fertility and reproductive success at a very fine scale. Thus, for example, there is a statistically significant difference in the number of children produced by couples related at the level of sixth versus seventh cousins (P = 1.4 x 10–7). Relationships at this genealogical distance are rarely known to the couples or their families and acquaintances in their social environment and are unlikely to influence factors such as age at the commencement of reproduction or the practice of consanguineous unions to preserve family property (4, 16).

Obama for president?

About a year ago I read Barack Obama’s book Dreams from my Father. To keep it short his Kenyan father while at a university in Hawaii met his to be Irish mother. The first part of the book is about that relationship or lack of one, and how his father left to go back to Kenya and his mother traveled in search of helping the world’s needy, though he spent very little time talking about his mother. He was raised almost entirely by his White grandparents, except for a short spell in Indonesia where he lived with his mother and her new Indonesian husband.

When he became a teenager he discovered his blackness, and with the help of other black friends he became the angry black man, rebellious, blaming whitey for his problems, and offended that he was not part of the Black culture. I have little doubt that if he becomes President, we will see initiatives to return to making equal outcomes for Blacks one of his primary agendas. His bringing the country together will fail miserably, in my opinion. The major damage he can do is to appoint judges who are in favor of entitlements for minorities, though the party regulars may be able to keep the more radical or unqualified from be appointed.

In 1972 the medical establishment had decided that infectious diseases were being eradicated in the developed world. It decided the future of medicine was finding solutions for the problems causes by non-infectious diseases.

The consensus was wrong on two counts. It did not foresee AIDS, Legionnaire’s disease, Ebola, Marburg, antibiotic-resistant TB, “flesh-eating staph, hepatitis C, and Rift Valley fever. Stomach ulcers and some forms of cancer and some forms of heart disease, definitely; all cancers and all heart diseases and diabetes, Alzheimer’s disease and schizophrenia are possibly caused by infections.

Race in humans: A reply to the “Statement on Race” by the American Anthropological Association (AAA)

This is a discussion section for the race FAQ at the wiki, which presently doesn't discuss all the things that it should, but it will be periodically updated. Suggestions for improvement and criticism will be appreciated. If you offer criticism, stick to scientific issues, and you better have the requistive scientific background.

Pauline Hanson and the abuse of DNAPrint testing for multicultural ends

Back in February this article by journalist Edmund Burke appeared in the Brisbane tabloid, Courier-Mail.  It was not very subtle in the way it set about its business:-

FORMER One Nation leader Pauline Hanson, the proudly outspoken proponent of polarising immigration policies, has discovered she is of Middle Eastern heritage.

When told of the results, the former fish and chip shop owner appeared flustered, making references to “rape and pillage” in ancient times, adding:
“All I can think of is that probably down the track it eventuated from some war.

“But I’m not going to knock it. It has made me who I am.”

Ms Hanson is not the only prominent Queenslander with a mixed racial background, with the same international testing process revealing that Premier Peter Beattie has even greater links to the Middle East.

Middle Eastern is defined for the test as modern-day Saudi Arabia, Iraq, parts of Iran, Syria and [removed] and the Arab countries of North Africa.

Greece and Turkey are defined as southeastern European while northern European is defined by countries such as England, Ireland and Scotland.

The tests use 176 genetic markers to trace racial ancestry back thousands of years and were carried out by Florida-based company DNAPrint Genomics.

When taking the test at her rural property outside Ipswich before Christmas, Ms Hanson, who recently attacked Muslims for “eradicating Australian traditions”, said she was confident her ancestry came from England and Ireland.

In December the right-wing firebrand, who once warned that Australia was in danger of being swamped by Asians, launched a fresh attack on black South Africans and Muslims.

David Sloan Wilson, group selection, culture

The following is a brief but interesting commentary from JW on a David Sloan Wilson paper (pdf) that, not surprisingly, was criticized by Razib on Gene Expression.

A few excerpts from the paper:-

Group selection provides the fitness differences that were lacking within groups. In the case of a no-cost public good, any variation among groups is sufficient for the A-type to evolve to fixation in the total population, because positive among-group selection is unopposed by within-group selection.  If providing a public good requires a private cost, then positive selection at the group level is opposed by negative selection at the individual level and the outcome depends upon the relative strength of the two processes.  More generally, groups can evolve into adaptive units that are designed to maximize their contribution to the total gene pool to the extent that selection among groups prevails against selection within groups. This is also part of the consensus that emerged in the middle of the 20th century; it remains theoretically valid today …

That sound thinking can be compared to Richard Dawkins’ absurd strawman argument against group selection, as quoted in OGI by Salter, in which he asks why lions don’t refrain from eating antelope, “for the good of the mammals” (or something to that idiotic effect).  I mean, hello, where is the selective pressure to result in such behavior?  Is “the good of the mammals” a selective pressure to out-compete the strong selective pressure on lions to be efficient predators on antelope (never mind that lions, as a group, can cooperate in hunting, but that’s another story)?

Robert Boyd, who has championed cultural group selection for as long as I have championed group selection in general, has stated that the received wisdom about genetic group selection is correct and that culture is required to make group selection a significant evolutionary force…

Here is where the biopolitical Salterians can find some common ground with the culturalist Yockeyians because Western High Culture may assist in forming the cultural input needed for making white group selection a “significant evolutionary force”.

Human cognition is usually assumed to be an individual-level process, even if the outcome of the cognition is adaptive at the group level (eg, an individual deciding to provide a public good at private expense).  Another possibility is that the group becomes the cognitive unit, with social interactions comparable to neuronal interactions.  The concept of a group-mind might sound like science fiction but its likelihood follows directly from multilevel selection theory, has been well documented in social insects, and is fully plausible for human groups…

Does MacDonald’s work describe such a human group-mind?

In closing, let’s note that there is some irony in Razib’s complaint that Wilson uses an unrealistic “pipe-dream” model to explain group selection (actually, on a small part of the overall paper).  Tame white GNXP blogger David B based his “Salter Intermarriage Fallacy” upon the wildly unrealistic scenario of exactly equal migration and intermarriage between all peoples and all nations – something that has never happened and will never happen.  Not that that bothered Razib.  Then again, David B’s “work” supports South Asian Diaspora interests.  Wilson’s work, if it catches the attention of the “wrong” people, may be understood to oppose those interests.  By the way, group selection is not necessary for the pursuit of EGI, it is a “why”, not a “what”.  But nevertheless, a study of group selection can inform as to methods to be used to rationally pursue genetic interest objectives.

Actually, the reverse may be true; incorporating concepts of EGI may bolster the significance of Wilson’s ideas, and may better explain the actions of those who provide public goods for their group even at some degree of private cost.
