Why We Fight (Over Land)“In the most recent issue of the journal International Security, Monica Duffy-Toft and Dominic Johnson, political scientists at Oxford, argue that a new theoretical framework is needed to analyze such behavior, one rooted in evolutionary biology…. As Duffy-Toft told me an interview today, ‘It comes back to survival and reproduction. There’s an instinct that we need land in order to exist. We need to have the capacity to get resources to live our lives….’ Duffy-Toft acknowledges that the thesis is controversial. While their piece is currently the lead article in International Security, one of the more prestigious journals in the field, it took almost 10 years to get it published. ‘We’re pushing up against real biases in our field,’ she says. ‘Scholars don’t want to admit that our behavior can be constrained by the fact that we’re animals.’ – *sigh* – original research article here [pdf].

Cochran-Harpending paper on “Amish Quotient”“‘[T]heir social pattern probably drives strong selection for a particular flavor of personality, which is downright fascinating and worthy of further investigation. One could, with difficulty and a lot of investment, identify dimensions of a hypothetical AQ. It would likely include affinity for work, perseverance, low status competition, respect for authority, conscientiousness, community orientation, and so on. We proposed (Cochran, Hardy, & Harpending, 2006) a similar mechanism to account for Ashkenazi Jewish evolution in Medieval times selecting for ability and success in white collar occupations.'” – from steve sailer. previously @west hunter: Inferring an AQ.

The Son Becomes The Father“The failure of parents to appreciably affect the outcomes of their children affirms Gregory Clark’s findings, and indicates that much of the transmission of status from one generation to the next is ultimately genetic in origin…. Almost certainly, throughout history, and across the diverse societies, that has been a huge amount of ‘noise’ in the transmission of status, especially on the individual level and in the short run. The vagaries of the circumstances no doubt imbued good fortune on some and dashed the success of many others. But through it all, the thing that is at the root of continuity – DNA – remained the active ingredient to propagate lineages in their respective places through out the ages.” – from jayman.

About That Gene-Environment Interaction Study by Turkheimer et al.“The upshot is that while environmental deprivation may render genetic differences less important in the determination of children’s IQ, the typical black child in this large and downscale sample had apparently not been raised in deprived circumstances any more frequently than the typical white child in the sample. The lower IQs of blacks in this sample cannot therefore be put down to them having been exposed to environments less conducive to the expression of genetic variance in IQ than the environments experienced by whites.” – @human varieties.

Dopamine D4 receptor gene variation influences self-reported altruism“[T]he DRD4 7-repeat allele is associated with lower scores on the NEO-PI-R Altruism facet scale, accounting for about 2% of the variance. As the DRD4 7-repeat allele has been associated with higher scores in impulsive personality traits and ADHD, our result suggests that individual differences in impulsive behavioral tendencies may play a role in the propensity to behave altruistically.” – h/t tom farsides!

“Natural Law” and Other Rationalizations of Morality“People worry about a ‘grounding’ for morality. There’s really no need to. As Marc Bekoff and Jessica Pierce pointed out in Wild Justice – The Moral Lives of Animals, there are analogs of moral behavior in many species besides our own…. Other animals don’t wonder why one thing is good and another evil. They’re not intelligent enough to worry about it. Hominids are Mother Nature’s first experiment with creatures that are smart enough to worry about it. The result of this cobbling of big brains onto the already existing mental equipment responsible for moral emotions and perceptions hasn’t been entirely happy. In fact, it has caused endless confusion through the ages.” – from helian.

Inclusive fitness theory for the evolution of religion“We describe and evaluate an integrative hypothesis for the origin and evolution of human religious cognition and behaviour, based on maximization of inclusive fitness. By this hypothesis, the concept of God is represented by one’s circle of kin and social salience, such that serving God and serving this circle become synonymous. The theory is supported by data from anthropology, evolutionary theory, psychology, neuroscience, psychiatry, endocrinology and genetics.” – h/t claire lehmann!

Speculations on the Evolution of Awareness“The ‘attention schema’ theory provides one possible account of the biological basis of consciousness, tracing the evolution of awareness through steps from the advent of selective signal enhancement about half a billion years ago to the top-down control of attention, to an internal model of attention (which allows a brain, for the first time, to attribute to itself that it has a mind that is aware of something), to the ability to attribute awareness to other beings, and from there to the human attribution of a rich spirit world surrounding us. Humans have been known to attribute awareness to plants, rocks, rivers, empty space, and the universe as a whole. Deities, ghosts, souls-the spirit world swirling around us is arguably the exuberant attribution of awareness.” – h/t neuroskeptic!

Mugshots Built from DNA Data“A computer program crudely predicts facial structure from genetic variations.”

The Oldest Living Things On Earth“Starting in the 1960s, evolutionary biologists have searched for an overarching explanation to account for all the different ways to grow old. The best-supported ones so far are variants on the old truth that a jack-of-all-trades is a master of none. An organism can collect a finite amount of energy, whether it’s a lion killing gazelles, a tulip capturing sunlight, or a microbe breathing iron at the bottom of the sea. It can use that energy to grow, to produce offspring, to defend itself against pathogens, to repair damaged its damaged molecules. But it has a limited budget. The energy spent on one task is energy that can’t be spent on others. Molecular repair and pathogen defense are both good ways to live longer. But a long-lived organism that produces few offspring will not pass on many copies of its genes to future generations. The organisms that will succeed are the ones that do a mediocre job of keeping their bodies in order, leaving more energy for making babies.” – h/t billare!

Mutation, Not Natural Selection, Drives Evolution – according to masatoshi nei: “Every part of our body is controlled by molecules, so you have to explain on a molecular level. That is the real mechanism of evolution, how molecules change. They change through mutation. Mutation means a change in DNA through, for example, substitution or insertion [of nucleotides]. First you have to have change, and then natural selection may operate or may not operate. I say mutation is the most important, driving force of evolution. Natural selection occurs sometimes, of course, because some types of variations are better than others, but mutation created the different types. Natural selection is secondary.”

End the Hype over Epigenetics & Lamarckian Evolution“They insist that characteristics many researchers assume to be the result of epigenetic inheritance are actually caused by something else. The authors list four possibilities: Undetected mutations in the letters of the DNA sequence, behavioral changes (which themselves can trigger epigenetic tags), alterations in the microbiome, or transmission of metabolites from one generation to the next. The authors claim that most epigenetic research, particularly when it involves human health, fails to eliminate these possibilities.” – h/t jayman!

New warning about ‘Celtic Curse’ blood iron disease“Hemochromatosis is a hereditary disease, linked particularly to Irish and those of Irish origin. It causes your body to absorb too much iron from the food you consume. The excess iron becomes stored in your organs, especially your liver, heart and pancreas. It can lead to life-threatening conditions such as cancer, heart problems and liver disease. Those with Irish heritage have a significantly greater chance of carrying the gene mutation that can contribute to the deadly disorder. Some experts believe that hemochromatosis originated more than 40,000 years ago in Ireland when genes mutated allowing the population to over-absorb iron, to compensate for a poor iron diet.” – h/t 23andMe!

The state is the worst wicked stepmother of all“[T]he number of children raised without one of their parents has increased sharply in recent years, partly due to changing sexual mores but also the involvement of the state itself; the largest increase in non-marital births came after the 1977 Homeless Persons Act gave lone mothers priority on housing lists. The Tory MP behind this proposal wrote, ‘The sad truth is that, until now, the Wicked Stepmother would have got away scot-free.’ Possibly, but there would not have been so many wicked stepmothers, or stepfathers, or mother’s current boyfriends, without the state in the first place.” – from ed west.

Pseudoescepticismo y biodiversidad humana“Desde hace años, sin embargo, existe una tendencia ideológica inflacionaria en el movimiento escéptico que tiende a alejarse del ‘núcleo’ original, cuyos contornos de todos modos son imprecisos (¿es la parapsicología una ciencia?). El inconveniente es que este alejamiento del núcleo, yo lo llamaría ‘escepticismo inflacionario’ o simplemente pseudoescepticismo, desdibuja los criterios de demarcación y hace que los nuevos temas sean más y más propensos a la contaminación moral e ideológica…. Un caso bastante claro es la campaña ‘escéptica’ de descrédito contra la psicología evolucionista, que sólo ha convencido a un pequeño grupo. ¿Pudiera ser que el empeño de grupos ‘escépticos’ de asimilar el movimiento de biodiversidad humana con el ‘racismo científico’ y con la ‘pseudociencia’ (la falacia moralista siempre merodeando) corriera una suerte parecida?” – @la revolución naturalista.

there’s nothing new under it, is there?

just reading Before France and Germany: The Creation and Transformation of the Merovingian World which picks up at the end of the roman empire, and boy does a lot of this sound awfully familiar! the scenario is not exactly the same as what we’ve got today, but a lot of the elements certainly seem to be — electing a new people, debasing the currency, robbing peter to pay paul (i.e. increasing taxes to pay off one’s pals), a general lack of foresight on behalf of so-called leaders. fascinating, but a bit depressing to see the same sorts of behavioral patterns being repeated over and over again. maybe time really is a flat circle. =/ kindle locations 234-263, 278-289:

“Political power within the Empire had long been a juggling act in which participated the senate, the army, and of course the emperor, but all three institutions up to the death of Commodus in 192 had been largely Italian. Over half of the senators were from Italy, and the remainder were, with few exceptions, drawn from the most strongly Latinized provinces-Spain, Africa, and Gallia Narbonensis. Moreover, since they had to invest a considerable amount of their wealth in Italian land, were required to attend meetings regularly in Rome, needed permission to travel outside of Italy, and tended to intermarry extensively, senatorial families of provincial origin rapidly became Italian, just as at a lower level of society, military families were becoming provincial. This senate owed its importance to constitutional, economic, and social factors. First, the constitutional tradition obliged an emperor to select senators to command all of his legions except the one in Egypt, to govern major frontier provinces, and to command the armies. Second, while the senate possessed a strong hereditary nucleus, it was in every generation open to a certain number of candidates who, along with the old established senatorial families, controlled enormous wealth, principally in land. This was especially true in the West, where even in times of crisis the poverty of the imperial treasury often contrasted with the private wealth of individual senators. Finally, through their networks based on political dependents and landholding throughout the Roman world, the influence of senators reached into every corner of the Empire. When provoked, the senate could be a formidable opponent to even the most ambitious emperor.

“Prior to the third century, the military power on which rested imperial control was still primarily found in the Praetorian Guard, that elite body of approximately 10,000 soldiers who served (and sometimes selected or eliminated) the emperor and his household. They were required to be Roman citizens, and, like the senators, were, until the end of the second century, largely drawn from Italy. Thus they too maintained the centrist Latin character of the Empire.

Not surprisingly, therefore, the emperors had all come from Italian families of senatorial rank. Whatever the differences between emperor, senate, and army-bitter, bloody, and brutal as they often were-these conflicts had been among parties that shared major cultural, social, and political values.

“With the reign of Septimus Severus (193-211) [who was only half roman-h.chick], the commander of the Danube army who was proclaimed emperor by his troops, began an important new phase of Roman history. The defenders of the provinces, and particularly those of the West, now came into their own as control of the Empire passed into the hands of those who had saved it — the frontier armies and their commanders. From the perspective of the old Italian senatorial aristocracy and the inhabitants of more settled and civilized areas, this was a period of disaster and crisis. A succession of provincial military commanders, often openly scornful of the senate, were raised to the purple by their armies, fought each other for hegemony, and were usually assassinated for their efforts when they proved incapable either of bringing victory against internal and external foes or of sufficiently enriching their supporters. The senate’s attempts to control the selection of the emperor was constantly thwarted by the tendency of the provincial armies to view succession as hereditary, particularly when the new emperor had come from the military. However, from the perspective of those in the frontier and particularly from Pannonia, it was a golden age. The Western legions had demonstrated their strength and their vitality, and as the Severans sought to consolidate their position they looked to the personnel and the models of their border armies for support.

“Initially Severus himself was willing to work with the senate of which he had been a member, but senatorial opposition led him to rely on the provincial army, which he and his successors rewarded with considerable pay increases, donatives or special bonuses, and the right to marry. The added expenses of this military largesse were financed through the liquidation of the vast wealth he confiscated from the senatorial opposition. His son, known to posterity by his military nickname Caracalla, expanded his father’s promilitary policy, raising soldiers’ pay by 50 percent. To finance this he resorted to two measures. First, as his father had done earlier, he debased the denarius, the silver coin used to pay the troops; within a few decades, this led to the total collapse of imperial coinage. Second, he doubled the traditional 5 percent inheritance tax paid by all Roman citizens, and, to expand the base of this tax, made all free inhabitants of the Empire Roman citizens. This latter measure acknowledged a largely de facto situation, since the distinction between citizen and foreigner no longer had much real significance. However it did strengthen the relative position of provincials in the Empire who, henceforth, from Britain to Arabia, looked upon themselves as Romans with the same rights and possibilities as Italians. These measures, like the increase of military pay, tended to strengthen the position of those peoples on the periphery of the Empire at the expense of those at the center, and those in a position to benefit most from these changes were soldiers and veterans….

“These crises, which led to an even more expanded role for the military, had ironically been caused by it. Because the Severans could never trust the senate to support them, they were forced to find ways to circumvent the role of the senate in commanding the military and to constantly augment the army salary to maintain its good will. This was financed by still more confiscations of senatorial property for real or imagined plots and by drastic devaluation of the silver coinage. This naturally further alienated the senate and brought about enormous problems in the financial stability of the Empire. Exacerbating all this was the fact that the provincial armies, having gotten a taste of their power as emperor-makers, set about it with tremendous vigor, assassinating emperors and raising others at a great rate. Between the death of Severus Alexander (235) and the ascension of Diocletian (284), there were at least twenty more or less legitimate emperors and innumerable pretenders, usurpers, and coregents. The longest reign during this period was that of a pretender, Postumus, who established himself as ruler of Gaul, Britain, Spain, and at times parts of northern Italy for nine years.

“The restoration of order by Diocletian solidified the increasing role of the military. Although credited with having separated civil and military administrations, under him and his successors the civil service was reorganized along military lines, hardly a surprising development given that during the third and fourth centuries the route to high office normally meant military service. Thus many ambitious civil servants either rose primarily through the military or spent some time in it. By the beginning of the fourth century, military organization and structure, along with the soldier’s cultural and political values, had become the primary model along which Roman society was ordered. But these soldiers were no longer the Italian peasants of an earlier age-increasingly they were the very barbarians they were enlisted to oppose.

which reminds me of a passage from another (very politically correct) book — Rome and its Frontiers: The Dynamics of Empire — that i quoted in a comment a while back [pgs. 205-212]:

“[I]n the later Roman Empire frontiers became softer and immigration control more lax at the same time as citizenship and ethnic distinctions within the Empire were becoming blurred. The universal grant of citizenship by the Constitutio Antoniniana of 212 AD was only a formal recognition by the state of a long process that had diminished the concept of citizenship and eroded the distinction between cives and peregrini in the provinces. By the fourth century status and wealth counted for more socially and legally than citizenship….

“To sum up, far from the homogenization of what the Constitutio Antoniniana called the patria communis, that is, the population of the Roman community, internal, social divisions became stronger. Ironically, however, the refinements of status distinctions and social divisions served as a more effective vehicle than any legal measure to allow immigrants to integrate at all levels. What mattered was not whether you were a citizen but whether you could attain equal social or economic status. In this respect, the Roman Empire of the fourth century was the reverse image of the nation-state in the nineteenth century. The juridical personality of the citizen was almost eliminated as frontier controls relaxed and as immigrants were accomodated in ever greater numbers….

“Immigrants provided substitutes for rural recruits, thus leaving agricultural workers on the land to increase state revenue, since they increased the capitation tax and added extra income through the system of adaeratio, which bought them exemption from the military levy. There clearly were concerns in the imperial chancellery for the tax regime and for the rents from imperial estates, which was reflected in contemporary legislation….

“These fiscal and economic benefits to rural production coincide with the concern expressed by the Gallic panegyricists about agri deserti and high taxes, and hence their praise for ‘so many farmers in the Roman countryside’, both as immigrants and as returning prisoners…. The essential point, however, is that…immigrants were officially perceived as good for the economy by bringing down the price of food and by servicing local markets through increased production.

“Whether the peasants of the Gallic countryside felt the same pleasure at the fall in market prices is another matter, and it may have provoked resentment. If modern experience is any guide, there is a sharp difference between economists, who calculate that immigrants are essential to economic growth, and popular opinion, which always believes that immigrants are undesirable because they depress the labor market. But there is no evidence to show that there was institutional, social discrimination against foreign-born workers, once settled inside the Roman Empire….”

…on roman latifundia undercut the native roman farmers. nihil novi sub sole, eh?:

“The first latifundia were accumulated from the spoils of war, confiscated from conquered peoples beginning in the early 2nd century BC. The prototypical latifundia were the Roman estates in Magna Graecia (the south of Italy) and in Sicily, which distressed Pliny the Elder (died AD 79) as he travelled, seeing only slaves working the land, not the sturdy Roman farmers who had been the backbone of the Republic’s army….

“The latifundia quickly started economic consolidation as larger estates achieved greater economies of scale and senators did not pay land taxes. Owners re-invested their profits by purchasing smaller neighbouring farms, since smaller farms had a lower productivity and could not compete, in an ancient precursor of agribusiness. By the 2nd century AD, latifundia had in fact displaced small farms as the agricultural foundation of the Roman Empire. This effect contributed to the destabilizing of Roman society as well. As the small farms of the Roman peasantry were bought up by the wealthy and their vast supply of slaves, the landless peasantry were forced to idle and squat around the city of Rome, relying greatly on handouts….

Pliny the Elder argued that the latifundia had ruined Italy and would ruin the Roman provinces as well. He reported that at one point just six owners possessed half of the province of Africa….” [wiki-p]
