Aristotle on heterogeneity as a cause of civil war

Aristot. Pol. 5.1303a
A difference of race (1) is also conducive to civil war, until they acquire a common spirit: just as a city (2) cannot come into being by a chance multitude, nor in a chance length of time: this is why, whoever has accepted co-settlers either in the beginning or later (3), most of the time they revolted.

στασιωτικὸν δὲ καὶ τὸ μὴ ὁμόφυλον, ἕως ἂν συμπνεύσῃ: ὥσπερ γὰρ οὐδ᾽ ἐκ τοῦ τυχόντος πλήθους πόλις γίγνεται, οὕτως οὐδ᾽ ἐν τῷ τυχόντι χρόνῳ: διὸ ὅσοι ἤδη συνοίκους ἐδέξαντο ἢ ἐποίκους, οἱ πλεῖστοι διεστασίασαν
Notes:

1. A. is not speaking of a difference of race (τὸ μὴ ὁμόφυλον) in the modern sense of continental groups; his examples following this passage all involve different Greek peoples who were involved in a common settlement. Indeed, the very word translated as "conducive to civil war" (στασιωτικὸν) refers to inter-Hellenic conflicts (cf. Plat. Rep. 5.470c, where the terminology of στασιάζειν is applied to "unnatural" inter-Hellenic conflicts, while war itself (πόλεμον) is reserved for inter-ethnic conflicts.)

2. Note that by city (πόλις), A. is not speaking only of the physical entity of a city, but rather its political identity, i.e., a city-state. A physical city can certainly exist with a "chance multitude", but A. warns that a city-state cannot, until a sufficient length of time has transpired for the different elements in it to acquire a common spirit.

3. A. uses the words συνοίκους and ἐποίκους. The first one denotes those who live together, and is usually used for those who participate in the act of foundation of a city-state. The second term denotes those who are later added to the population, after the city has already been established.

Aristotle's emphasis on common descent (ὁμόφυλον) as a preventive factor against war seems strange by present-day norms, especially since he is speaking of the co-existence of different sets of Greeks, rather than the co-existence of different ethnic groups, or even different races.

This is why he does not suggest that the possibility of peaceful cohabitation is inherently impossible, but that it takes a long time, until the constituent elements "acquire a common spirit" (ἕως ἂν συμπνεύσῃ).

It appears that Aristotle did believe in inherent differences between nations (cf. Aristot. Pol. 1.1252b, 7.1327b) which would presumably make the possibility of acquiring a "common spirit" even more remote, if not impossible. States with a Greek and non-Greek citizen body were unheard of at his time, so the issue does not seem to have even crossed his mind.

Regional homogeneity of mtDNA in Sweden

Int J Legal Med. 2009 Jul 10.

Homogeneity in mitochondrial DNA control region sequences in Swedish subpopulations.

Tillmar AO et al.

In order to promote mitochondrial DNA (mtDNA) testing in Sweden we have typed 296 Swedish males, which will serve as a Swedish mtDNA frequency database. The tested males were taken from seven geographically different regions representing the contemporary Swedish population. The complete mtDNA control region was typed and the Swedish population was shown to have high haplotype diversity with a random match probability of 0.5%. Almost 47% of the tested samples belonged to haplogroup H and further haplogroup comparison with worldwide populations clustered the Swedish mtDNA data together with other European populations. AMOVA analysis of the seven Swedish subregions displayed no significant maternal substructure in Sweden (F (ST) = 0.002). Our conclusion from this study is that the typed Swedish individuals serve as good representatives for a Swedish forensic mtDNA database. Some caution should, however, be taken for individuals from the northernmost part of Sweden (provinces of Norrbotten and Lapland) due to specific demographic conditions. Furthermore, our analysis of a small sample set of a Swedish Saami population confirmed earlier findings that the Swedish Saami population is an outlier among European populations.

Metric and non-metric variation of Ainu

Am J Hum Biol. 2009 Jul 10.

Metric and nonmetric dental variation and the population structure of the Ainu.

Hanihara T.

Gene flow and genetic drift are important factors affecting geographic variations in human phenotypic traits. In the present study, the effects of gene flow from an outside source on the pattern of within- and among-group variation of the Ainu from Sakhalin Island and three local groups of Hokkaido are examined by applying an R-matrix approach to metric and nonmetric dental data. The comparative samples consist of their ancestral and neighboring populations, such as the Neolithic Jomon, the subsequent Epi-Jomon/Satsumon, the Okhotsk culture people who migrated from Northeast Asia to the northeastern part of Hokkaido during a period 1600-900 years B.P., and modern non-Ainu Japanese. The results obtained by using the census population sizes of the regional groups of the Ainu as an estimate of relative effective population size suggest the possibility of an admixture between the Okhotsk culture people and the indigenous inhabitants in Hokkaido, at least in the coastal region along the Sea of Okhotsk. Such gene flow from Northeast Asian continent may have exerted an effect on the genetic structure of the contemporary Ainu. The present findings indicate that the population structure, as represented by genetic drift and gene flow, tend to be obscured in the results obtained by standard statistical methods such as Mahalanobis' generalized distance and Smith's MMDs. The present extension of the R-matrix approach to metric and nonmetric dental data provide results that can be interpreted in terms of a genetically, archaeologically, and prehistorically suggested pattern of gene flow and isolation.

Intermarriage and the risk of divorce in the Netherlands

Prompted by my recent post on Constantinus Porphyrogenitus and inter-ethnic marriage.

From the paper:
We therefore introduce two hypotheses. The first hypothesis is the main-effects hypothesis, which argues that the more traditional the value orientation of a religious or national origin group, the lower the risk of divorce.

...

Our second hypothesis concerns the effect of the spouses’ religion and national origin, and argues that when the religions or national origins of the two spouses are dissimilar, the risk of divorce is higher.We call this the heterogamy hypothesis. Assumingthat the main-effects hypothesis is valid, we need to decide what constitutes evidence for the heterogamy hypothesis. If the divorce risk of a mixed marriage (between, say, a member of group A and a member of group B) is higher than the divorce risk of AA marriages but lower than the divorce risk of BB marriages, we argue that adaptation is taking place. The behaviour of those couples is in between the two groups, and one can argue that this is simply the average of the two group effects and not a heterogamy effect (Jones 1996). To analyse real heterogamy effects, we employ both a strong and a weak form of the heterogamy hypothesis. According to the strong heterogamy hypothesis, AB marriages will have a divorce risk that is higher than the maximum divorce risk of AA and BB marriages. For example, we expect that a marriage between a Catholic and an unaffiliated person will have a divorce risk that is higher than the (already) high risk for unaffiliated couples. According to the weak heterogamy hypothesis, AB marriages will have a divorce risk that is higher than the average risk of AA and BB marriages. In our example, the risk of the mixed group will be higher than the average of the low risk for Catholics and the high risk for unaffiliated couples.
The data is supportive of the strong heterogamy hypothesis, according to which an AB has a higher chance of a divorce than the highest of AA and BB:
Are there effects of heterogamy on the risk of divorce? Table 8 shows that the answer is clear: most mixed combinations have a risk of divorce that is higher than the highest level of divorce in the two homogamous groups. The average ratio is 2.02, indicating that mixed marriages have a risk of divorce twice as high as that of the maximum level of divorce in the two corresponding groups. This effect is quite strong and clearly supports the strong heterogamy hypothesis.

...

We also find variations in the magnitude of the effects that are consistent with our hypothesis about value orientations. Combinations of Dutch and Turkish or Moroccan persons reveal a stronger heterogamy effect than combinations involving Dutch and Western European persons. The effects for combinations involving Southern Europeans are in between the combinations with Turks or Moroccans and the combinations with Western Europeans. When looking at combinations involving
minority men, the differences are quite strong. The ratio is 4.7 for combinations involving Turkish men, 2.4 for combinations involving Moroccan men, and 1.5 for combinations involving Western European men. Because European groups are more similar than Moroccan and Turkish groups to the Dutch in values and lifestyle, this finding is consistent with theoretical interpretations of the heterogamy effect
in terms of value similarity.
The paper has detailed tables on the various combinations of intermarriage between different Dutch religious denominations and national origins. What seems clear is that Constantinus' ideas about religious and ethnic homogamy as more conducive to harmonious cohabitation seem to be supported by the data.

Intermarriage and the risk of divorce in the Netherlands: The effects of differences in religion and in nationality, 1974-94

Matthijs Kalmijn et al.

A textbook hypothesis about divorce is that heterogamous marriages are more likely to end in divorce than homogamous marriages. We analyse vital statistics on the population of the Netherlands, which provide a unique and powerful opportunity to test this hypothesis. All marriages formed between 1974 and 1984 (nearly 1 million marriages) are traced in the divorce records and multivariate logistic regression models are used to analyse the effects on divorce of heterogamy in religion and national origin. Our analyses confirm the hypothesis for marriages that cross the Protestant-Catholic or the Jewish-Gentile boundary. Heterogamy effects are weaker for marriages involving Protestants or unaffiliated persons. Marriages between Dutch and other nationalities have a higher risk of divorce, the more so the greater the cultural differences between the two groups. Overall, the evidence supports the view that, in the Netherlands, new group boundaries are more difficult to cross than old group boundaries.

Analysis of five Neandertal Genomes (Briggs et al. 2009)

This is a very exciting paper, both for the apparent advance in ancient DNA technology, and for the finding of a smaller effective population size for Neandertals. The reduced mtDNA diversity in Neandertals might be the result of selection. Even among current cold-adapted populations, mtDNA diversity is reduced, and this is due to bioenergetic adaptation for a cold climate.

Chemistry World has some details on the new technical advance:
Now, Pääbo and colleagues have created a quicker, less expensive, and less wasteful method to reconstruct the genomes of ancient specimens. 'The samples we used in this new project were even more poorly preserved than that original sample [analysed last year], meaning that the shotgun method would have cost hundreds of millions of pounds,' says graduate student Adrian Briggs who helped pioneer the new technique. 'Hence the need for our new targeted retrieval method - primer extension capture (PEC).'

'We have managed to immortalise a precious DNA source, for example a Neanderthal DNA extract, by making many thousands of copies of every original DNA molecule in that source,' says Briggs. In doing so, ancient DNA sequences can be stored in a 'library' they can be used again and again. The technique uses 5'- biotinylated oligonucleotide primers and a DNA polymerase that isolate Neanderthal mtDNA sequences from the plethora of contaminant DNA. Sequences of interest are then directly extracted from this amplified library of degraded DNA before the sequencing step. 'This saves on experimental time and costs by several thousand fold,' Briggs adds.

Eske Willerslev, an expert on ancient DNA at the University of Copenhagen, Denmark, thinks this is an important technological breakthrough. 'The capture approach makes it possible to retrieve very short pieces of DNA (50-70bp) that is difficult if not impossible using regular [ approaches,' he comments. 'This means that the chances of retrieving endogenous rather than contaminant DNA increases significantly.'
The much publicized Neandertal DNA data from Vindija cave were taken from an almost ideal sample in terms of preservation.

LiveScience has some details on the implications for the demography of Neandertals:
In fact, new genetic evidence from the remains of six Neanderthals (Homo neanderthalensis) suggests the population hovered at an average of 1,500 females of reproductive age in Europe between 38,000 and 70,000 years ago, with the maximum estimate of 3,500 such female Neanderthals.

"It seems they never really took off in Eurasia in the way modern humans did later," said study researcher Adrian Briggs of the Max-Planck Institute for Evolutionary Anthropology in Germany.

The research, which will be published in the July 17 issue of the journal Science, suggests the small population size of our ancestral cousins may have been a factor in their demise.

"Because there never really were millions of them, they probably were more susceptible to some event that made them go extinct, which to me, suspiciously coincides with the emergence of modern humans," Briggs told LiveScience.

Ian Tattersall, curator of anthropology at the American Museum of Natural History in New York, who was not involved in the current research, said the study "does support notions that toward the end of last ice age, the Neanderthal population was declining as a result of harsh circumstances." He added, "I don't believe Neanderthals would've gone extinct if it wasn't for this new element, the Homo sapiens competing for the same resources."
I really find it hard to believe that Neandertals died out beause of competition with Homo sapiens. After all, a population of a few thousand could quite easily have been accommodated in Paleolithic Europe; population density was so low, that there were plenty of resources for modern humans and Neandertals alike.

There are plenty of scenaria for the disappearance of the Neandertals, ranging from absorption by modern humans (although recent estimates of introgression are usually from modest to very low) to cannibalism, to contracting diseases brought by Homo sapiens and for which they had no immunity. We don't even know how long the co-existence between the species was before the disappearance of Neandertals. The argument for a causative role of modern humans in Neandertal demise is weakened if the latter persisted for many thousands of years after the arrival of the former.

If, however, Neandertals were so limited in numbers, perhaps there was no major reason for their disappearance. It could very well have been a statistical accident as random fluctuations in population size may have driven them to a non-viable demographic size from which they may not have been able to recover.

As usual for a Science paper, there are plentiful open access supplementary data.

Targeted Retrieval and Analysis of Five Neandertal mtDNA Genomes

Adrian W. Briggs et al.

Abstract

Analysis of Neandertal DNA holds great potential for investigating the population history of this group of hominins, but progress has been limited due to the rarity of samples and damaged state of the DNA. We present a method of targeted ancient DNA sequence retrieval that greatly reduces sample destruction and sequencing demands and use this method to reconstruct the complete mitochondrial DNA (mtDNA) genomes of five Neandertals from across their geographic range. We find that mtDNA genetic diversity in Neandertals that lived 38,000 to 70,000 years ago was approximately one-third of that in contemporary modern humans. Together with analyses of mtDNA protein evolution, these data suggest that the long-term effective population size of Neandertals was smaller than that of modern humans and extant great apes.

mtDNA from the Carpathian Highlands

Hum Biol. 2009 Feb;81(1):43-58.

Mitochondrial DNA sequence variation in the boyko, hutsul, and lemko populations of the carpathian highlands.

Nikitin AG et al.

Abstract Genetic studies of the distribution of mitochondrial DNA (mtDNA) haplogroups in human populations residing within the Carpathian Mountain range have been scarce. We present an analysis of mtDNA haplogroup composition of the Boykos, Hutsuls, and Lemkos, three population groups of the Carpathian highlands. In our study Hutsuls had the highest frequency of subhaplogroup H1 in central and eastern Europe. Lemkos shared the highest frequency of haplogroup I ever reported and the highest frequency of haplogroup M(*) in the region. MtDNA haplogroup frequencies in Boykos were different from most modern European populations. We interpreted these unique mtDNA frequencies to be evidence of diverse and dynamic population histories in the Carpathian highland region.

Constantinus Porphyrogenitus on inter-ethnic marriage

Constantinus VII was a 10th c. Byzantine Emperor.

Constantinus Porphyrogenitus, De administrando imperio, Ch. 13
Because each nation has different customs and divergent laws and institutions, it must hold its own things, and perform the associations necessary for the continuation of life from the same nation. As every animal mixes with those of the same genus, so has it been established as a just thing for every nation to form marriage partnerships not with people of a different race and language, but of the same genus and speech. Because, herein grows sameness of mind, and intercourse, and friendly discourse, and cohabitation. But different customs and divergent laws give birth rather to dislikes and conflicts and hatreds and civil wars, which do not bring about friendship and intercourse, but enmity and dissent.

ἕκαστον γὰρ ἔθνος διάφορα ἔχον ἔθη καὶ διαλλάττοντας νόμους τε καὶ θεσμοὺς ὀφείλει τὰ οἰκεῖα κρατεῖν καὶ ἀπὸ τοῦ αὐτοῦ ἔθνους τὰς πρὸς ἀνάκρισιν βίου κοινωνίας ποιεῖσθαι καὶ ἐνεργεῖν. ὥσπερ γὰρ ἕκαστον ζῷον μετὰ τῶν ὁμογενῶν τὰς μίξεις ἐργάζεται, οὕτω καὶ ἕκαστον ἔθνος οὐκ εξ ἀλλοφύλων καὶ ἀλλογλώσσων ἀλλ’ ἐκ τῶν ὁμογενῶν τε καὶ ὁμοφώνων τὰ συνοικέσια τῶν γάμων ποιεῖσθαι καθέστηκε δίκαιον. ἐντεῦθεν γὰρ καὶ ἡ πρὸς ἀλλήλους ὁμοφροσύνη καὶ συνομιλία καὶ προσφιλὴς συνδιατριβὴ και συμβίωσις περιγίνεσθαι πέφυκε· τὰ δε ἀλλότρια ἔθη καὶ διαλλάττοντα νόμιμα ἀπεχθείας μᾶλλον καὶ προσκρούσεις καὶ μίση καὶ στάσεις εἴωθεν ἀπογεννᾶν, ἅπερ οὐ φιλίας καὶ κοινωνίας ἀλλ’ ἔχθρας καὶ διαστάσεις φιλεῖ ἀπεργάζεσθαι.

The punishment of treason in ancient Athens

"Archeptolemus son of Hippodamus, the Agrylian, and Antiphon son of Sophilus, the Rhamnusian, being both present in court, are condemned of treason. And this was to be their punishment: that they should be delivered to the eleven executioners, their goods confiscated, the tenth part of them being first consecrated to Athene; their houses to be levelled with the ground, and in the places where they stood this inscription to be engraved on brass, '[The houses] of Archeptolemus and Antiphon, traitors.'

That Archeptolemus and Antiphon should neither of them be buried in Athens, nor anywhere else under that government. And besides all this, that their posterity should be accounted infamous, bastards as well as their lawful descendants;  and he too should be held infamous who should adopt any one of their descendants for his son. And that all this should be engraved on a brass tablet, and that tablet should be placed where that stands on which is engraved the decree concerning Phrynichus."

Andreas Willi on Macedonia

Andreas Willi has written a rebuttal of sorts (pdf) to the letter of the Macedonia Evidence Initiative. It is an extremely interesting piece of doublethink, and as such, it is useful to address in some detail.

Willi (henceforth W.) writes:
The internet documentation which is referred to in the letter may be right when it sees nothing but “a personal grudge” behind Demosthenes’ calling Philip II a “barbarian,” but to cite Herodotus 5.22 as conclusive evidence that Alexander the Great was “thoroughly and indisputably Greek” is seriously misleading, since Herodotus’ statement “I happen to know that [the forefathers of Alexander] are Greek” is triggered precisely by the existence of a dispute over the matter, long before the age of Demosthenes.
Indeed, there was a dispute over the matter, but the key point is that the dispute was resolved in favor of the Macedonian claims of Hellenicity. So, if the Hellanodikai of ancient Olympia accepted the Macedonian king as a Hellene, what reason does W. have to doubt them? Indeed, this acceptance occurred a century and a half at least before the ascent of Macedonians as a great power, so there is no reason to think that the judges' acceptance was the result of pressure.

Thus, we know that Alexander affirmed his Hellenicity --by choosing to compete at the Olympic games-- and this affirmation (and that of his successors who also competed) were affirmed by the other Greeks. We have both a proclamation and an acceptance of his Hellenicity.

W. writes:
As for (b), the question “Why was Greek the lingua franca all over Alexander’s empire if he was a ‘Macedonian’?” cannot be adequately answered with the words “[Because] Alexander the Great was Greek,” given that we have numerous examples of ancient empires in which the lingua franca was not the language of the ruler.
The unnamed examples of "ancient empires" notwithstanding, it is the case that Empires usually spread their own language. The Romans much esteemed Greek as a language of learning, but they spread Latin, not Greek to most of their Empire. Centuries later, the Europeans, who much esteemed Latin, spread Spanish or English to their empires.

Languages are spread by people, and Empires spread the languages of their peoples. What wondrous miracle would result in myriads of Macedonians settling throughout Asia not to leaving a single trace of their non-Hellenic presence? Did the Macedonians decide to abandon their language at precisely the time of their own triumph? A simpler explanation is that they did not.

But, here comes the doublethink, as W. writes of the ancient Paionians:
What is at the core of the letter is a mistaken and unhealthy notion of historical identity. “While it is true that the Paionians were subdued by Philip II, father of Alexander, in 358 B.C. they were not Macedonians and did not live in Macedonia”—but is that really so? How many Paionians did we ask about it, and at what point in history?
Thus, W. questions the letter's statement that the Paionians were not Macedonians. None of the ancient sources ever confuse the two people, or assert that the Paionians were Macedonians. But, let us grant, for the sake of argument, that at some point in their history, the Paionians felt like Macedonians.

But, if feelings sufficed, then how can W. deny the feelings of the Macedonian kings to be Hellenes? If Paionians may be Macedonians since they may have considered themselves to be such, how can W. simultaneously cast doubt to the claims of the Macedonian kings to be Hellenes, when they certainly did consider themselves to be such.

W. continues:
The comparison with Egypt is awkward, for at least after the incorporation of “Paionia” under Antigonos Gonatas (249 BCE) a territorially continuous political unity had come into being which survived as such in the Roman provincial administration. That the case of Egypt is rather different in this respect need hardly be stressed.
Suppose that Paionians did start feeling like Macedonians during Roman times. Certainly, in Strabo's time, who lived after the Roman conquest, the Paionians continue to be reckoned as a different people, while Macedonia is reckoned as part of Hellas. But, let's suppose that indeed a "Macedonian identity" formed.

But, then, in Byzantine times, the Macedonian theme, consisted of a completely different region, in Thrace. So, whatever, "Macedonian" identity may have formed, it was no lasting thing, having disappeared by medieval times, and transferred to Thrace. Thus, the argument that FYROM Slavs can be seen as inheritors of a distinctive "Macedonian" identity from antiquity collapses. Their only relationship to Macedonia is that they happen to live in what was the Ottoman province of Macedonia.

W. writes:
Moreover, to use an ancient but immediately relevant analogy, are we really to think that Thucydides got it all wrong when he wrote that, decades before the conquest of Paionia, the term “Macedonia” also applied to lands not inhabited by “ethnic” Macedonians (Thuc. 2.99)?
But, Thucydides statement actually opposes W's argument:
Assembling in Doberus, they prepared for descending from the heights upon Lower Macedonia, where the dominions of Perdiccas lay; [2] for the Lyncestae, Elimiots, and other tribes more inland, though Macedonians by blood and allies and, dependents of their kindred, still have their own separate governments. [3] The country on the sea coast, now called Macedonia, was first acquired by Alexander, the father of Perdiccas, and his ancestors, originally Temenids from Argos. This was effected by the expulsion from Pieria of the Pierians, who afterwards inhabited Phagres and other places under Mount Pangaeus, beyond the Strymon (indeed the country between Pangaeus and the sea is still called the Pierian gulf) of the Bottiaeans, at present neighbors of the Chalcidians, from Bottia, [4] and by the acquisition in Paeonia of a narrow strip along the river Axius extending to Pella and the sea; the district of Mygdonia, between the Axius and the Strymon, being also added by the expulsion of the Edonians. [5] From Eordia also were driven the Eordians, most of whom perished, though a few of them still live round Physca, and the Almopians from Almopia. [6] These Macedonians also conquered places belonging to the other tribes, which are still theirs--Anthemus, Crestonia, Bisaltia, and much of Macedonia proper. The whole is now called Macedonia, and at the time of the invasion of Sitalces, Perdiccas, Alexander's son, was the reigning king.
It is clear from this passage that Macedonians e.g., the Lyncestae) existed outside the Macedonian state, while some people who lived within it were not reckoned as Macedonians. Macedonians and the "Kingdom of Macedonia" are not conterminous entities. Thucydides does not assert that the non-Macedonians within the Macedonian state become, by reason of their inclusion in this state, Macedonians.

Thus, there were non-Macedonians within the Kingdom of Macedonia, and none of the independent self-governing Macedonians listed by Thucydides lived in present-day FYROM.

W. writes:
But to call Cleopatra a “Macedonian” gives away what constitutes true identity in the eyes of the letter’s authors: to them, identity seems defined by ancestry and blood-lines, by the past more than the present. Are we then to conclude that, for example, John F. Kennedy—or George W. Bush or Barack Obama, for that matter—were never real Americans? And if John F. Kennedy’s ancestors spoke Irish at one point, is it preposterous for all English-speaking Americans to use him today in their construction of a national identity because of that?
On what basis was Cleopatra not a Macedonian? She was a Macedonian by blood, and indeed by a fairly inbred pedigree full of Macedonians. But, suppose we discount, for the sake of argument, the importance of ancestry. Why, still, was Cleopatra not a Macedonian?

According to W. the conquered Paionians became Macedonians on account of them being conquered, but Cleopatra, the descendant of the conquerors of Egypt became a non-Macedonian, and, presumably, an Egyptian.

In W's strange world of doublethink, it appears that conquerors become the conquered (Cleopatra becomes an Egyptian), and the conquered become the conquerors (Paionians become Macedonians).

W. continues the JFK analogy:
By coming to America John F. Kennedy’s ancestors chose to become Americans (with Irish roots); but why could the Slavs coming to Macedonia then not become Macedonians (with Slavic roots)?
The analogy is false, for several reasons. First of all, JFK's ancestors came to the US as peaceful immigrants while the Slavs came to Macedonia as enemies of the local inhabitants. One needs to read the Miracula Sancti Demetrii to see what the local Macedonians thought of Slavs during the time of their arrival.

But, for the sake of argument, let's accept that the Slavs after several centuries, and because they live in part of Ottoman Macedonia, have some reason to consider themselves some kind of Macedonian. If this was all they did, no Greek would mind; after all, Greeks speak of Turkocretans, or Turkocypriots, or Slavomacedonians.

No, the real issue is that the Slavs of FYROM want to usurp the rights to the use of Macedonians exclusively for Slavs. Consider the official FYROM state policy about the existence of a "Macedonian" minority in Greece, which is -supposedly- oppressed by Greeks.

Going back to the Irish immigrants example, imagine if Irish immigrants not only started calling themselves Americans, but also started speaking about an American minority (by which they meant Americans of Irish origin) oppressed by "Anglos." That is, they tried to dispossess the original bearers of the name and take it as their property. Yet, this is precisely what FYROM Slavs are attempting to do.

W. writes:
No matter what its ethnic mix was—and what serious scholar would nowadays want to argue that the only “good” states are ethnically “pure” states, in which everyone must speak the same language?—the tendentiously-labeled “pseudo-greater Macedonia,” far from being a recent invention, did exist as a real recent invention, did exist as a real identitarian concept well before the 20th century. And in a sense its roots can be traced back to the conquests of Philip II, Alexander the Great and their successors in “Paionia”; for if those conquests had never taken place, the history of the region would have looked different and the territory of “Paionia” might not have shared the fate and fortune of “Aegean” Macedonia for long stretches of its history. Thus, unless one subscribes to a dangerous “blood-and-soil ideology,” there is no reason why the modern Slavic Macedonians should not be allowed to continue to call their country “Macedonia” and to pride themselves in Alexander the Great just as much as the modern Hellenic Greeks do. What does it matter if Alexander “was Greek, not Slavic,” as long as no one claims the opposite?
This is a truly peculiar argument. Alexander's conquests influenced the history of much of the known world, so, should they all be called Macedonians on account of being conquered by the actual Macedonians?

Also, what can one make of the statement about sharing the "fate and fortune"? Was a Macedonian Greek in any case closer to a Skopje Slav because they both happened to live in a territory that Ottoman Sultans claimed to be Macedonia? Was he not closer --Ottoman borders notwithstanding-- to a Thessalian or Thracian Greek? If we abandon the "blood-and-soil ideology", should we replace it with a "borders-and-history ideology", whereby an annexation of Paionia 23 centuries ago has forever marked the territory as Macedonia?

FYROM Slavs may, of course, feel pride that the ancient Paionians were conquered by Philip and Alexander a thousand years before their linguistic ancestors came to Macedonia. I don't feel particular pride that Greece was conquered by the Romans or the Ottomans or the Nazis, but there's no accounting for taste.

One cannot fail to notice, however, how thoroughly un-Macedonian this attitude is. Philip and Alexander loved Greek culture, and proudly proclaimed their Greekness, while these modern "Macedonians" despise Greeks, and proudly proclaim their non-Greekness. I submit this as exhibit A in the case that they are not, indeed, Macedonians at all.

Restricted geographic distribution for Y-Q* paragroup in South America

Graciela Bailliet et al.

Abstract

We analyzed 21 paragroup Q* Y chromosomes from South American aboriginal and urban populations. Our aims were to evaluate the phylogenetic status, geographic distribution, and genetic diversity in these groups of chromosomes and compare the degree of genetic variation in relation to Q1a3a haplotypes. All Q* chromosomes from our series and five samples from North American Q* presented the derivate state for M346, that is present upstream to M3, and determined Q1a3* paragroup. We found a restrictive geographic distribution and low frequency of Q1a3* in South America. We assumed that this low frequency could be reflecting extreme drift effects. However, several estimates of gene diversity do not support the existence of a severe bottleneck. The mean haplotype diversity expected was similar to that for South American Q1a3* and Q1a3a (0.478 and 0.501, respectively). The analysis of previous reports from other research groups and this study shows the highest frequencies of Q* for the West Corner and the Grand Chaco regions of South America. At present, there is no information on whether the phylogenetic status of Q* paragoup described in previous reports is similar to that of Q1a3* paragroup though our results support this possibility.

mtDNA of Hakka and Chaoshanese

Tracing the origins of Hakka and Chaoshanese by mitochondrial DNA analysis

Wen-Zhi Wang et al.

Abstract

Hakka and Chaoshanese are two unique Han populations residing in southern China but with northern Han (NH) cultural traditions and linguistic influences. Although most of historical records indicate that both populations migrated from northern China in the last two thousand years, no consensus on their origins has been reached so far. To shed more light on the origins of Hakka and Chaoshanese, mitochondrial DNAs (mtDNAs) of 170 Hakka from Meizhou and 102 Chaoshanese from Chaoshan area, Guangdong Province, were analyzed. Our results show that some southern Chinese predominant haplogroups, e.g. B, F, and M7, have relatively high frequencies in both populations. Although median network analyses show that Hakka/Chaoshanese share some haplotypes with NH, interpopulation comparison reveals that both populations show closer affinity with southern Han (SH) populations than with NH. In consideration of previous results from nuclear gene (including Y chromosome) research, it is likely that matrilineal landscapes of both Hakka and Chaoshanese have largely been shaped by the local people during their migration southward and/or later colonization in southern China, and factors such as cultural assimilation, patrilocality, and even sex-bias in the immigrants might have played important roles during the process.

Y chromosome and mtDNA of eastern Aleuts

Ann Hum Biol. 2009 Jul 8:1-16. [Epub ahead of print]

Mitochondrial DNA and Y-chromosome variation in five eastern Aleut communities: Evidence for genetic substructure in the Aleut population.

Zlojutro M, Rubicz R, Crawford MH.

Since Russian contact in 1741, the Aleut communities of southwestern Alaska have undergone a series of demographic upheavals stemming from forced relocations, disease epidemics, population bottlenecks, and pervasive admixture with European populations. This study investigates the impact of key historical events on the genetic structure of the Aleut population through analysis of mitochondrial and Y-chromosome DNA variation in five eastern Aleut communities. Results from HVS-I sequencing and Y-chromosome typing reveal patterns of variability that exhibit east-west geographic differentiation for the major Aleut haplogroups. This finding is underscored by SAMOVA and Monmonier analyses that identify genetic discontinuities between eastern and western Aleut populations. The majority of Aleut Y-chromosomes were characterized to haplogroups of mostly Russian, Scandinavian and Western European origin (approximately 85%), which is in stark contrast to the 3.6% of Aleut mtDNA lineages identified as non-Native American, and thus indicating a large degree of asymmetrical gene flow between European men and Aleut women. Overall, this study identifies a significant relationship between geography and genetic variation in the Aleut population, with a distinct substructure along an east-west axis that reflects the combined effects of founder events in aggregate island communities, male-biased gene flow from European populations, and the original peopling of the Aleutian Archipelago.

Human remains from the Moravian Gravettian

Human remains from the Moravian Gravettian: morphology and taphonomy of additional elements from Dolní Vestonice II and Pavlov I

E. Trinkaus et al.

Abstract

Zooarchaeological analysis of the earlier Mid Upper Paleolithic (MUP) (Pavlovian) assemblages from Dolní Vstonice II and Pavlov I, southern Moravia, have yielded 11 additional remains from Dolní Vstonice II (five of which may be associated) and 20 remains from Pavlov I (16 of which come from a pair of hands, Pavlov 31). These remains are those of early modern humans, albeit with a few generally archaic features. At least two of them represent very tall individuals, among the tallest known for the Upper Paleolithic. These remains also raise the question, previously posed, as to the nature of differential treatment of the dead among MUP humans, given the presence of ritual burials, isolated bones and (with Pavlov 31) selected associated anatomy.

A highly annotated whole-genome sequence of a Korean individual

Jong-Il Kim et al.

Abstract

Recent advances in sequencing technologies have initiated an era of personal genome sequences. To date, human genome sequences have been reported for individuals with ancestry in three distinct geographical regions: a Yoruba African, two individuals of northwest European origin, and a person from China1, 2, 3, 4. Here we provide a highly annotated, whole-genome sequence for a Korean individual, known as AK1. The genome of AK1 was determined by an exacting, combined approach that included whole-genome shotgun sequencing (27.8times coverage), targeted bacterial artificial chromosome sequencing, and high-resolution comparative genomic hybridization using custom microarrays featuring more than 24 million probes. Alignment to the NCBI reference, a composite of several ethnic clades5, 6, disclosed nearly 3.45 million single nucleotide polymorphisms (SNPs), including 10,162 non-synonymous SNPs, and 170,202 deletion or insertion polymorphisms (indels). SNP and indel densities were strongly correlated genome-wide. Applying very conservative criteria yielded highly reliable copy number variants for clinical considerations. Potential medical phenotypes were annotated for non-synonymous SNPs, coding domain indels, and structural variants. The integration of several human whole-genome sequences derived from several ethnic groups will assist in understanding genetic ancestry, migration patterns and population bottlenecks.

Two comments on ancient mtDNA from Native American coprolites

They are referring to the paper by Thomas et al. which detected mtDNA haplogroups A2 and B2 in pre-Clovis Americans. The arguments are highly technical, so I won't express an opinion on who of the two is right.

My default position is to have a question-mark next to every ancient DNA study, whether it has been formally criticized or not. Only when a large number of such studies from a similar time/place and by different researchers produce similar results, will we be justified, I think, to remove that question mark.

Comment on "DNA from Pre-Clovis Human Coprolites in Oregon, North America"

Hendrik Poinar et al.

Gilbert et al. (Reports, 9 May 2008, p. 786) analyzed DNA from radiocarbon-dated paleofecal remains from Paisley Cave, Oregon, which ostensibly demonstrate a human presence in North America predating the well-established Clovis complex. We question the authenticity of their DNA results and argue that in the absence of intact stratigraphy and diagnostic artifacts, and in view of carbon isotope anomalies, the radiocarbon dates of the oldest specimens are unreliable.

Response to Comment by Poinar et al. on "DNA from Pre-Clovis Human Coprolites in Oregon, North America"

M. Thomas et al.

The arguments of Poinar et al. neither challenge our conclusions nor would contribute to the verification of our data. We counter their questions about the authenticity of our ancient DNA results and the reliability of the radiocarbon data and stand by the conclusion that our data provide strong evidence of pre-Clovis Native Americans.

Climate has driven mtDNA variation in humans

Yann Klimentidis points me to this very exciting new paper. Some of its authors also contributed to another recent paper which investigated the role of climate in shaping human cranial variation.

The authors compared autosomal, X chromosome and Y chromosome genetic variation with that of mtDNA. For example an impressive 85% of autosomal microsatellite diversity in worldwide humans can be explained by their distance from Africa, but no apparent effect is seen for climate. The effect of distance from Africa is only 18% for HVS-I of human mtDNA, and a strong effect of climate measures (such as temperature) is seen. On the contrary, human Y chromosomes show no relationship with climate.

The effect of climate is also resilient to accounting for distance from Africa (which is very hot, and thus distance from it might be expected to correlate with a decrease in temperature; it is not), and by removing populations living in extreme arctic conditions, for which thermoregulation is of the utmost importance.

I would say that this paper represents the best evidence so far of selection acting on the human Y chromosome.

The implications of this are manifold, and they relate:

(i) to the use of mtDNA to assess population relationships. For example, South Asians have a strong affinity with West Eurasians in their Y-chromosomes and with East Asians in their mtDNA. Nonetheless they do not occupy an intermediate position between the two in autosomal DNA, but are predominantly aligned to West Eurasians.

(ii) to the overall mitochondrial time depth of humanity, i.e., the age of mitochondrial Eve, and what that implies about the recentness of our species (it may be older than its mtDNA time depth), and its possible admixture with other human populations such as Neandertals (it may have occurred, but the non-modern mtDNA may have been selected against)

(iii) to the potential of solving, at least in part, discrepancies between present-day and archaeological mtDNA gene pools, which may not in fact reflect processes of migration, but climate shifts over time.

Note that this is not the first time that adaptive evolution of human mtDNA has been proposed. For example five years ago, Ruiz-Pesini et al. noticed the conservation of internal branch amino acid substitutions at high latitudes, and made the case for energy-related climate adaptation in human mtDNA. The current paper makes a different argument, but arrives at a similar conclusion.

Climate shaped the worldwide distribution of human mitochondrial DNA sequence variation

François Balloux et al.

Abstract

There is an ongoing discussion in the literature on whether human mitochondrial DNA (mtDNA) evolves neutrally. There have been previous claims for natural selection on human mtDNA based on an excess of non-synonymous mutations and higher evolutionary persistence of specific mitochondrial mutations in Arctic populations. However, these findings were not supported by the reanalysis of larger datasets. Using a geographical framework, we perform the first direct test of the relative extent to which climate and past demography have shaped the current spatial distribution of mtDNA sequences worldwide. We show that populations living in colder environments have lower mitochondrial diversity and that the genetic differentiation between pairs of populations correlates with difference in temperature. These associations were unique to mtDNA; we could not find a similar pattern in any other genetic marker. We were able to identify two correlated non-synonymous point mutations in the ND3 and ATP6 genes characterized by a clear association with temperature, which appear to be plausible targets of natural selection producing the association with climate. The same mutations have been previously shown to be associated with variation in mitochondrial pH and calcium dynamics. Our results indicate that natural selection mediated by climate has contributed to shape the current distribution of mtDNA sequences in humans.
